Difference Between LED and LCD

This post is to update our previous post on What should we consider when buying LCD monitor .Due to the new computer hardware technology has been introduced by display monitor industry,the new technology that coming in is LED backlight display.It eventually will replace the current trend LCD monitor.

LED is very light and thick

If you planing to upgrade your PC and getting a biggest display monitor ,you might consider LED instead of LCD.You might still consider LCD since the price is droping and some model is really will worth to buy.,below are some points to consider when buying LED monitor .

What is the difference between LED and LCD

*LED Backlight vs CCFL backlight:LED monitor refers to a monitor that uses LED as a backlight instead of CCFL Backlight,it provide thinner and power efficiency and greater image quality.

* Hardware Signal Input divide: video inputs like VGA, DVI and HDMI are important, as is the stand, which should be height-adjustable if possible.

* Viewing angles should be wide. The generic name 'LCD screen' covers three different panel technologies, with TN being the cheapest and most common but with the least open viewing angles.Stand from difference viewing angles and check it yourself.

* The panel should be responsive to the input signal. If it isn't, then fast-moving objects will look blurry.

* Colours can be anywhere from completely wrong to absolutely perfect. It's something you need to examinate yourself instead of knowing from review of others user.

* Energy consumption on the monitors ,ranging from 22 to 80 W in comparable situations.Basically larger screen consume more power that smaller screen.Think carefully do you really really need such big screen for your computer desktop?

PC Monitor New Features LED backlight

What to consider when buying PC display monitor?
Display monitor is part of the computer hardware and it involve almost 30% of the cost of computer,Display technology currently moving faster that we though ,the industry are facing major challenges with pressure of over-supply and prices decreasing quicker than expected.

New features introduced recently is LED,as you might already know , LCD is overtaking CTR monitor several years ago for it siez,,optional to built-in digital tuner,which you can use your monitor to watch TV, display and convert the movie in 3D using special glasses,etc.And now the innovative new display technology moving in is LED with use LED backlight..For your information ,previously we are using CCFL backlight display technology aka LCD.LED will have wider viewing angles and slimmer than LCD.


Innovative New Features is LED
The continuing transition to LED backlights is motivating LCD TV panel manufacturers to develop their supply chains in order to reduce the cost of LED-backlit panels.
According to the latest Quarterly LED Backlight Panel Shipment and Forecast Report, 9.5 million, or 18.5%, of the LCD TV panels that shipped in Q2’10 had LED backlights, which was 110% growth Q/Q. LCD TV panel makers are targeting aggressive growth for LED panel shipments, with plans to reach 40% LED penetration in Q4’10, and to exceed 50% in Q2’11.

Penetration is highest among leading LCD TV panel makers, including Samsung, LG Display, AUO, Sharp, and Chimei Innolux. Notably, Samsung and Sharp aim to ship more LED LCD TVs than CCFL panels in Q4’10 (Table 1). Among these players, Sharp is the only one focusing on direct-type LED backlights, as opposed to the more common edge-lit structure.

Table 1. Panel Makers’ Plans for Q4’10 - LCD TV Panel Shipments by Backlight

Backlight Type	AUO	Chimei Innolux	CPT	IPS Alpha	LG Display	Samsung	Sharp
LED	26.9%	26.9%	18.0%	6.5%	38.1%	58.3%	65.5%
CCFL/Others	73.1%	73.1%	82.0%	93.5%	61.9%	41.7%	34.5%

Source[2]: Quarterly LED Backlight Panel Shipment and Forecast Report

“LCD TV panel prices fell quickly in Q3’10 due to oversupply and inventory adjustments downstream. However, LED panel prices are falling even faster than CCFL.” noted David Hsieh, Large-Area LCD Research Team Leader and Vice President of the Greater China Market for DisplaySearch. Hsieh added, “Panel makers are expecting to grow their shipments through the end of the year as LED panel prices and end-market retailer prices of LED LCD TVs fall rapidly.”

After the tight supply in Q2’10, the LED backlight supply chain ramped up to meet panel makers’ production schedules. Furthermore, panel makers are investing vast resources to develop lower cost LED backlights with enhanced performance. Some of the technology development efforts include “single-sided two light bars”
edge-lit LED backlights, the use of alternative optical films for higher brightness and lower cost, as well as enlargement of LED chip packages for better luminous efficiency. These technologies will pave the way for another wave of LED penetration.

In Q2’10, the leading size of LED TV panel shipments was 40”, with a 23% share among all LED LCD TV panels shipped. This was followed by 32” with 21% share, 46” with 15%, and 42” with 11%. Shipments of 37” LED panels grew the fastest—642% from Q1’10 to Q2’10. In terms of LED panel manufacturing, Samsung and Sharp each shipped 2.8 million LED LCD TV panels in Q2’10, with 29% market share each. LG Display followed slightly behind with 2.4 million units and a 25% share, while AUO shipped 1.2 million units with 13% share. As a result, the leading four companies accounted for 96% of the total shipment of LCD TV panels with LED backlights.

Display Search also found that many system integrators or brands that have their own LCD module assemblies are also buying LCD cells from panel makers such as Chimei Innolux and AUO, and then assembling the LED backlight with their own design. The backlight, module, and system integration business models of leading manufacturers are helping to drive rapid LED penetration.

The Quarterly LED Backlight Panel Shipment and Forecast Report also examined LED panel shipment and penetration in desktop monitor and notebook PC panels. LED penetration for desktop monitor panels shipped in Q2’10 was 13.1%, and panel makers have set targets to exceed 30% by the end of the year. LG Display, AUO, and Chimei Innolux are leading in LED monitor panel shipments. In terms of notebook PCs, LED penetration soared to 92% in Q2’10.

Which And What HDTV You Should Buy.Honest Preview

Everyone talks about "HD" nowadays,What You Know About HDTV - High definition television ?

You might use your computer or LCD to watch movie ,but the screen resolution might not a HD capable.Do you know what is missing?

The HDTV,(also known as high definition Television) has become more and more popular nowadays. There are many well-known brands that have come out many new models of the HD style TV.

There are in different sizes, styles and colors that can be attributed to a HD television.And, there are selling in different price level depends on the features and brand.

Before making your decisions on which HDTV you should buy,let study and knowing what HDTV all about,and do a bit reserve on the background for HDTV.

Your might not know,HDTV has been created since the mid 1960s. In Japan, the first model of the HDTV was created. The innovative electronic geniuses of the United States were quick to follow and the race to perfecting the high definition technology was off to the races around the mid 1990s.

Basically, the term HD (High-definition) refers to the quality of the broadcast signal that is sent through the television set. The high definition signal represents images that are as crystal clear and life like as possible.

The Resolution of HD
Resolution is the corn factor why HDTV looks so much better than standard television. When a high-definition TV showing or broadcasting a high-definition source, a million or more pixels combine to create images that appear sharper and more realistic than TV ever has before.That the reason why when you are watching a program via the HDTV, you will amazed on the crystal clear image that show on the screen and you will quickly understand why it is becoming the favorite method of watching TV!Simply because it damn clear.

You might seem those numbers...1080i , 1080p etc.So what it is all about?

• 480p = 338,000 pixels / frame
• 720p = 922,000 pixels / frame
• 1080i = 1,037,000 pixels / frame
• 1080p = 2,074,000 pixels / frame

Well ,it simply mean the more pixers it has the better it performed. Note that 1080p represents about twice the amount of the resolution information as standard HD and contains six times the information in DVD resolution. 

Whats Wide Screen
The HD signal is digital in nature and provides viewers a 16:9 wide screen format, the same as used in movie theaters. The incredible, lifelike images displayed through HD televisions are unbelievable! You can literally feel like you at the racetrack or on the football field! If you are watching a concert, you will have a front row seat to the magical madness, too!

Many of the leading television manufacturers make at least one model of the HD television set,some made several hi end HDTV that equip with state of the art features,with slim and elegant design. There are multiple sizes of the HDTV available, from as small as 13 inches to as large as 85 inches! Top manufactures  including: Sony, Panasonic, Samsung, Sharp, Toshiba, Hitachi, RCA, JVC, Mitsubishi, Pioneer ,ETC.

 Check out these Ultimate HDTV Series By BRAND and Modal:

• Sony BRAVIA
• Toshiba Regza
• Sharp Aquos G series 
• Panasonic TX series
• Samsung LE series
• JVC LT series
• Hitachi UltraVision

Don't be confused,LCD TV doesn't the only media we can use to watch HD movie.(I know LCD TV is very popular and good price nowadays).For your infomation,there are three different formats that offer the HD technology, including:

3 types of HDTV to choose from


1.CRT (paints the image onto the screen. This style is perfect in any lighting condition and from every angle.).but the sigz made it take over by the LCD and Palsama TV.

Rear-projection CRT televisions are older technology. CRT TV's use three separate cathode ray tubes to create red, green, and blue and the TV combines the three beams before magnifying and projecting the image. The screen quality isn't as good as Plasma or LCD technology.

2.LCD (uses 2 different polarized, transparent panels to house a liquid in the middle.) Flat-Panel LCD TVs (liquid crystal display) technology are designed to create sharp, bright images in any lighting condition. LCD flat screen TV models work by shining light through pixel cells, with each cell containing a red, green, and blue component.

3.Plasma (digital images at a high resolution are created.). Be sure to do a little research to find the format that you will prefer.Plasma TVs are the thinnest of all types of high definition televisions. You can find a huge range of widths, from 36, right up to 72" inches that offer amazing color accuracy and saturation.

 On top of that we also need to know there are two types of HD system that found on the HD TV.i.e.HDTV-ready and the one that already build in.

#1.HDTV-ready
HDTV-ready is the definition for a television that is capable high definition programming with the installation of a receiver or tuner.

#2.Internal HDTV Receiver
An integrated system is a television with a built in HDTV receiver.It enabling you to watch programming right out of the box. If you are not sure as to which brand, size or format you prefer, there are many resources that you can access to make the decisionbefore buying HDTV that suit your need.

 To summarize ,a Digital TV that is able to "DISPLAY" TV signals in HDTV-Resolution - 720p - 1080i or 1080p - is "HDTV-Capable." A Digital TV that is HDTV-Capable - AND - has an 'Internal' HDTV Receiver is called an "Integrated" HDTV. A Digital TV that can display HDTV-Resolution Pictures, but requires an 'External' HDTV Receiver is commonly referred to as an HDTV-Capable 'Monitor'.

Those who had have made a purchase of an HDTV, probably posted a HDTV reviews online.These reviews can be found by searching from the internet ,just search for the keyword: The HDTV brand + review . One thing you should be aware of is that there might have fade review or testimonial if the review is from the seller site.


 No one likes to spend their hard earned money on a product that they would have never given a second glance, had they been forewarned.

When you are in the middle of don't know which HDTV to buy, the LCD TV is a perfect choice! There are many sizes, styles nowadays and most importantly the prices has drop to the acceptable level.

Buy one for your home or business. If you demand High-definition motion imaging,the HDTV will fit your choice.

What's DIY custom built pc

Lee Stewart. The owner of Custo Comp an independent online computer builder selling cheap gaming pcs and the very best equipment in the custom built pc market, Custo comp also sell cheap laptops and cheap desktop pcs.

Know what is DIY custom built pc

What is custom built pc? What is the directory between standard factory line PC to DIY (do it yourself)PC?How to you getting started to build your very own DIY pc?

"There is no difference between buying a standard factory line PC from Dell and buying a custom built PC from an independent online computer builder, provided you do a bit of research and make sure you are buying from a reputable and trustworthy online computer builder"

The phrase "custom built pc" is usually assumed to mean "Do it yourself "PC (aka "DIY")While for other products the term "custom built" might mean expensive for personal computers the opposite is usually the truth.

When purchasing a brand name computer you typically only have a few options, which means you have to pay for the features and components some corporate executive thinks you need. That can add up, especially since those corporate executives have a vested interest in selling you the more expensive of their features and hardware components.

The cost of brand name

On top of that, you also pay for the brand. A computer emblazoned with "Hp" or "Dell" is going to cost more than the same exact computer that carries no brand label. It used to be that buying a brand name was worth the extra cost for the guaranteed quality. But nowadays there are a lot of totally competent and even outstanding computer makers that operate under their own label or no label at all.

The diffrence between brander PC and custom built PC

There is no difference between buying a standard factory line PC from Dell and buying a custom built PC from an independent online computer builder, provided you do a bit of research and make sure you are buying from a reputable and trustworthy online computer builder.

Consider that many big computer makers get most of the individual components to build their branded computers from independent suppliers. An independent online computer builder can get the same components from the same suppliers and build the same computer, and then charge less for it.

And this doesn't go only for cheap desktops (which via an independent custom built pc supplier can be REALLY cheap). Cheap laptops can also be had by going the custom built pc route.

In recent years a number of small independent online computer builders have actually done such a reat work of custom building laptops that they have today become successful large businesses and now produce factory line models themselves.

The Quality of custom built PC

As quality goes, you need not lose anything by going with an independent online computer builder over a large brand. Large brands generally try to avoid cheating their customers in terms of quality, as doing so would sully their brand and kill their ability to make sales. But independent online computer builders also assume their customers will come back to them time and time again, so naturally they are keen to give their customers the best products at the best prices too.

So just as with anything else you plan to purchase online (even brand name products) doing a bit of research into who is the most reliable provider of a custom built PC in your area is a prudent first step. The small amount of time you will need to invest into doing so will find more than adequate return in the hundreds of dollor you could save on your new computer. Just searching for the term 'custom built pc' on Google for example, doing so will return a wealth of interesting results for you to pick your way through.

Tips on choosing computer mouse

Written By: Rebecca Beckett.Rebecca Beckett is a freelance writer for Innuity.For more information about ergonomic mouse or finger mouse, go to Cirque.

"we spend a lot of time at our desks. It is essential that we create the perfect ergonomic workspace"

How to choose the computer mouse

Choosing the right ergonomic equipment for your office space can make a world of difference. It might mean coming home feeling less physically tired or stressed because your body will feel so much better.

There are many different types of computer mouse in the world today. Several examples include the finger mouse, the wireless mouse or the mouse pen. Here are a couple tips that you should follow when looking for that perfect ergonomic mouse for you.

Hand Position
Consider the position your hand is in when it is on the mouse. Make sure it feels comfortable and allows your hand to remain in a natural position. When standing, your hand should fall at an angle. Many ergonomic mice may have an angled surface to imitate a natural position.
Rest your Wrist
If you don’t have one already, make sure your mouse has a wrist rest. It should be connected to the mouse pad so that it remains stationary and allows you to completely rest your wrist. Generally you will find these rests made out of a gel or flexible type of material to provide ultimate comfort. And actually, it should be your palm resting on the rest and not your actual wrist.

While these two ideas may seem common and simple, they need to be used more in the workplace. Employers need to provide their employees with the necessary equipment. Let’s face it – we use our mouse so frequently – it is an obviously essential piece of office equipment. This is why it is one of the hottest selling items in the computer market today.

One of the main ways that the mouse has changed over the years is that developers have created the infrared movement sensor.

This has allowed the mouse to become more ergonomic and has eliminated the need for the roller ball. Next, they made it wireless. No more wrists jerking to loosen up those tangled cords. And, you must admit, it’s nice not having to clean out that roller ball when it gets clogged.Okay, so you’ve shopped around and have chosen your new ergonomic mouse. You’ve positioned it on your desk just right with the wrist rest. Even with the top of the line ergonomic mouse, ergonomic experts still say that using keyboard shortcuts whenever possible is still much better for you and probably faster in the long run too.

Even though you may now have the best ergonomic mouse – don’t forget about the other things too. Make sure you have a good chair and that you are sitting up straight in it. Consider a footrest.

Why not try out an ergonomic keyboard. Think about a glare filter on your computer screen to help with those headaches. And above all else – take a break! Rest your wrists, your eyes, your back and your head. Take a deep breath and stretch.

One thing is certain: we spend a lot of time at our desks. It is essential that we create the perfect ergonomic workspace.

From the office chair we sit in all day to the keyboard we type each e-mail on – it’s all essential. However, don’t forget that small piece of office equipment it is so easy to overlook: The ergonomic mouse.

What to consider when puchase a CPU

What is CPU?What terms to consider when buying a CPU?

The CPU (central processing uni) It's the brains of the computer. Sometimes referred to simply as the central processor,but more commonly called processor, the CPU is where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.

Multi-Core Processors.
Multi-core refers to a CPU that includes more then one complete execution cores per physical processor. It combines multi (Minimum two) processors and their caches and cache controllers onto a single integrated circuit (silicon chip). It is basically two /more than two separate processors in one box.

The trend is expanding very fast .Currently,The dual core are what most popular choice .
Dual-core processors are well-suited for multitasking environments because there are two complete execution cores instead of one.

Judging from the current trend, it is with the mainboard, memory and other computer accessories of the rapid upgrade to support the Multi core Processors platform .The trend will gradually enter the mainstream application areas, the decline in prices of four core processors will also pave the way for the popularity.


FSB
The FSB is a short form for Front Side Bus.It's the connection between the CPU and system memory.The Front Side Bus operates at a speed which is a percentage of the CPU clock speed.The faster the speed,the better the performance of the CPU.


The Cache
The purpose of a cache is to enable the CPU to access recently used information very quickly.
A cache will significantly affect CPU performance..A cache operates at a certain speed in (kb) A typical L1 cache is 256Kb and a typical L2 cache is 1MB.The larger the cache,The larger the cache, the better the system performance boost.But it also depends on the CPU. Some caches operate at the full speed of the CPU, while others operate at half that speed or less.

The Battle is between AMD vs. Intel.

As the CPU database currently stands, there is a wide array of processors that you can compare although the list of applications you can compare may leave something to be desired.

Update!!

Laptop versus a desktop pc.How to choose?

You might find yourself asking that question many times while shopping for a computer. This guide offers you the pros and cons of owning a laptop versus a desktop pc.

Processing speed
Comparing processing speeds, laptops usually lag behind their desktop counterparts. With the rapid advance in microchip technology, the gap between them will become smaller.
Wireless
Most laptops especially those with Intel mobile chips come with wireless capability out of the box. This means you can get online from any location at home easily without ugly wires if you have a wireless network setup at home. Desktop pcs do not typically provide this capability out of the box although that may change in the near future.

Memory
Memory chip tends to be more expensive in Laptop than desktop pcs. If you buy a laptop with less than 512MB ram, be prepare to pay more for memory upgrades than you have to with a desktop pc.
Graphics Display
Because of the size of a laptop, most business or entry level laptop use integrated graphics with limited ram. This means most laptops even some expensive ones cannot run graphics intensive applications or 3d games as well as a desktop pc. With a desktop pc, you can buy a dedicated graphics card just to serve a graphics intensive application.
Portability
Portability is why everyone wants a laptop these days. Because of their size and weight, it is easier to carry a laptop around as opposed to a desktop pc.
Screen Display
Everyone buy laptop for their portability so laptops usually do not come with screens as big as their desktop counterparts. The screen technology used is usually not as good as those used by desktop pc. Furthermore with a desktop pc, you can always upgrade to a bigger and better screen whereas for laptop you are stuck with the same screen display for the whole lifespan of the laptop.
Upgradeability
Laptops do not offer many upgrade options. You can only upgrade memory and hard disk. With a desktop you can upgrade almost anything and only limited by the motherboard. This means a cheap desktop pc offers a longer lifespan than a laptop.
So whether you should buy a cheap laptop or a cheap desktop, ask yourself what are your needs? If you want to be able to use a computer wherever you go, then you are looking at a laptop to fulfill your needs. However if you do not require the portability of a laptop, play a lot of 3D games, graphic intensive applications, if you care about upgradeability to prolong the lifespan of your investment, then desktop pc is a smarter choice for you.

How to Buy a Flash-Based MP3 Player part 2

Continue From previous title:How to Buy a Flash-Based MP3 Player part
The most important consideration for many is price. If you're looking for something for $100 or less, you've got plenty of options; you can expect few extras and a capacity of 1GB or less. For around $150, you can get a player with lots of extra features, and at $200 you start moving into the higher capacities like 2GB and up. The highest-capacity flash-based players cost $250 to $299, and I'm not expecting those prices to drop very much before the end of this year.


Your best bet for getting the biggest bang for your buck, of course, is to read PC Magazine 's MP3 player reviews and use our online comparison tool to see the differences among players side-by-side. And nothing beats going to your local electronics shop and checking out your potential purchase in person before plunking down your hard-earned cash.

Below are three of the best flash-based MP3 players I've seen so far. The iPod nano (up to 4GB) is still the winner in terms of style, ease of use, software/hardware integration, and sound quality. The Samsung Yepp YP-Z5 (up to 4GB) is very similar to the iPod nano in design and pricing. Its controls aren't quite perfect, but it does offer PlaysForSure support—as well as impressive 30-hour battery life. While not offered in the large capacities of the other two, the Cowon iAudio U3 (up to 2GB) blows them away on extra features. (And it is now PlaysForSure-compatible via a recent firmware upgrade.) The iPod nano has a constellation of optional accessories available for it to add in other functions like FM radio, and accessories for the Z5 are starting to appear as well. Find out what else distinguishes these flash-based MP3 players from one another in our comparison table.

If you're looking for a little flash in your life, one of these MP3 players could be right up your alley. Read on to find one that fits your listening needs.

How to Buy a Flash-Based MP3 Player- by Michael Kobrin

The flash-based MP3 player market has gotten fairly complex, thanks to an ever-changing cast of characters and an explosion of new features. But there is a path through the maze, and it begins with understanding what you need, and what you're willing to spend.

Let's start with what you need: something that works with whatever computer you have. If you have a Windows-based PC, all players are compatible, including Apple iPods. If you have a Mac, you've got two options: an iPod, or a device that is USB Mass Storage Class–compliant (USB MC), meaning it can be plugged into a computer without software installation and be managed via drag-and-drop. Many popular players work only with Windows Media Player (WMP) on machines running Windows, and some USB MC players can work with WMP as well.

You should also consider how tech-savvy you (or the person you're buying for) are. There are no-fuss-no-muss players that you simply take out of the box, plug in to your computer, and drag music onto; then there are players that require a little bit of fiddling around with software like iTunes or Windows Media Player—and in some cases, with additional proprietary software. USB MC players are best for nontechies who don't have huge music collections. Of course, iPods are also very easy to use, thanks to their excellent integration with iTunes. Devices that work only with Windows Media Player tend to be somewhat more challenging to manage because the hardware/software integration isn't as polished.

Advertisement
If you plan on using online download or subscription services like Napster and Yahoo! Music Unlimited, you need a player that is compatible with Microsoft's PlaysForSure (aka Windows Media DRM 10). Note, too, that tracks purchased from Apple's iTunes Music Store will work only on iPods.

Right Hear, Right Now It's best to figure out in advance how much listening you plan to do per day and how long you're likely to have to go in between charges. Some MP3 players use alkaline batteries, which may be the best solution for those who are away from computers or outlets for extended periods of time. Also, many players don't come with an AC adapter, so you have to charge them via a PC's USB port. The average player gets between 12 and 16 hours of battery life, though a few can go for several days before running out of juice.

Next, figure out what you want in terms of physical size, capacity, and features. (If you don't care about how big or what shape the player is, skip directly to capacity.) Style mavens will want something thin and sleek like the iPod nano or Samsung Yepp YP-Z5 that can slip into any pocket without ruining the lines of your clothes.

Flash players' capacity currently tops out at 4GB with the lone exception of SanDisk's 6GB player. Unless you use your MP3 player only at, say, the gym, you'll probably want at least 1GB of storage space. The general belief is that you can fit 250 songs per gigabyte, but this depends entirely on the quality of your music files. In real-world usage, you can expect from 200 to 225 songs per gigabyte.

The iPod nano and iPod shuffle aren't the most feature-rich players out there, but they do what they do very well in terms of sound quality and ease of use. That said, the sound quality of most MP3 players is more than adequate, though I do run across some that just don't cut it. Ease of use is another matter: Apple's click wheel is still king, though manufacturers like iriver are looking to change that with some interesting new designs. I dislike the little joysticks and touchpads on many players because they're just not very precise; I prefer buttons, with very few exceptions.

Aside from music playback, the three most important extra features for many users are photo/video playback, recording, and FM radio. Handy features like photo playback, FM radio, and voice recording are quickly becoming standard on MP3 players, as are less-useful features such as line-in recording. If you like to watch movie trailers or other short video clips, there are a host of video-capable flash players, though none of them have impressed me with the quality and smoothness of video (not to mention that the screens tend towards the eye-squintingly tiny). Language learners and aspiring musicians may want to look for other niche features like A-B repeat, which lets you loop a section of a song or audiobook.

Right on Tracks All digital music players can play MP3 files, which is sufficient for most users. Be aware, however, that iPods won't play WMAs, and very few non-Apple players play AAC files (and none but iPods play protected AAC tracks). If you're concerned with getting the best sound quality possible, and you're planning to upgrade the player's headphones for something better, you may want your player to support a lossless compression format like Apple Lossless (iPods only), FLAC (supported by a few non-Apple players), or WMA Lossless (supported only by a small handful of Windows Mobile-based players).

Buying Guide to Graphics Cards

What should we consider when buying a Graphics Cards?What the factors that influenced the performance of the Graphics Cards? Below provide some tips on how to we buy a value to money Graphics Cards .Let's get started.

Buying Guide to Graphics Cards.

The graphics card is a vital performance component of your computer, particularly if you play 3D games, or work with graphics and video content. The graphics card sits in an expansion card slot in your PC and it is specifically designed to process image data and output it to your monitor, enabling you to see it. A graphics card works by calculating how images appear, particularly 3D images, and renders them to the screen. 3D images and video images take a lot of processing capacity, and many graphics processors are complex, require fans to cool them and need direct power supply. The graphics card consists of a graphics processor, a memory chip for graphics operations, and a RAMDAC for display output. It may also include video capture, TV output and SLI and other functions. You can find the graphics card that suits you by comparing specification between brands and vendors online.



Graphics Cards

What are your needs?

The first decision you need to make is whether you need a graphics card for handling 3D images or whether you are simply requiring 2D image rendering. For 2D requirements, you need only a low-cost solution. In many cases, an integrated graphics solution will suffice for 2D applications.

However with 3D graphics, the performance of the graphics card will impact directly on the frame rate and image quality of 3D programs and games. The differences between the low and high-end cards can be substantial, both in cost and performance.

Rendering 3D graphics is like lighting a stage, both the geometry of the shapes in question and the lighting of it need to be taken into account. The geometry of an image calculates the parts of an object that can and can't be seen, the position of the eye and its perspective. The lighting is a calculation of the direction of the light sources, their intensities and the respective shadows that occur. The second part to presenting a 3D image is the rendering of colours and textures to the surfaces of the objects, and modifying them according to light and other factors.

Most modern graphics cards include a small microchip called the Graphics Processing Unit (GPU), which are provide the algorithms and memory to process complex images. They reduce the workload of the main CPU, and provide faster processing. Different graphics cards have different capabilities in terms of processing power. They can render and refresh images up to 60 or more times per second, calculate shadows quickly, create image depth by rendering distant objects at low resolution, modify surface textures fluidly and eliminate pixelation.

What Specifications to Consider

Processor clock speed

This impacts on the rendering capability of the GRU. The clock speed itself is not the critical factor. Rather it is the per-clock performance of the graphics processor, which is indicated by the number of pixels it can process per clock cycle.

Memory size

This is the memory capacity that is used exclusively for graphics operations, and can be as much as 512MB. The more demanding your graphics applications are, the better you will be served with more memory on your graphics card.

16-32M
64M
128M
256M
512M
640M and more

Memory bandwidth

One thing that can slow down 3D graphics performance is the speed at which the computer delivers information to the graphics processor. A higher bandwidth means a faster data transfer, resulting in faster rendering speeds.

Shader model

DirectX Shader Models allows developers control over the appearance of an image as it is rendered on screen, introducing visual effects like multi-layered shadows, reflection and fog.

Fill rate

This is the speed at an image can be rendered or "painted". This rate is specified in texels per second, the number of 3D pixels that can be painted per second. A texel is a pixel with depth (3D). The fill rate comes from the combined performance of the clock speed of the processor and the number of pixels it can process per clock cycle, and will tell you how quickly an image can be fully rendered on screen.

Vertices/triangles

Graphics chips don't work on curves, rather they process flat surfaces. A curve is created by multiple flat planes arranged to look like a curve. 3D objects are created with multiple triangular surfaces, sometimes hundreds or even thousands, tessellated to represent the curves and angles of the real world. 3D artists are concerned with the number of polygons required to form a shape. There are two different types of specification: vertices per second (I.e., angles the triangles), and triangles per second. To compare one measure with the other, you have to take into account the fact that adjacent triangles share vertices.

Anti-aliasing

A technique used to smooth images by reducing the jagged stepping effect caused by diagonal lines and square pixels. Different levels of anti-aliasing have different effects on performance.

RAMDAC

The Random Access Memory Digital to Analogue Converter takes the image data and converts it to a format that your screen can use. A faster RAMDAC means that the graphics card can support higher output resolutions. Some cards have multiple RAMDACs allowing that card to support multiple displays.

TV-out

Some graphics cards provide the option to connect a television via either a composite (RCA) or S-Video connector. TV Out

S-video Out
S-video In and S-video Out (VIVO)
YPbPr Connection for HDTV

DVI

Some graphics cards include a connector for DVI monitors, handy because a lot of LCD screens support DVI. DVI offers better image quality than the standard VGA connector.

Dual-head

Dual-head is a term used when two monitors are used side by side, stretching your desktop across both.

SLI (Scalable Link Interface.)

With SLI you can couple two graphics cards in your computer, enabling each card to take half the rendering thereby doubling the performance.

When considering your graphics card, it pays to think about how much you need your computer to process your graphics output. Using a high end graphics card with a high pixels per clock rating, large memory, fast processor and other features means that you can run the latest games efficiently, or work in intensive graphics development.

Different Models

While there are many vendors of graphics cards, there are actually only two major manufacturers of chips for graphics cards. Nearly every graphics card on the market features a chip manufactured by either ATI or Nvidia. Cards using the same graphics chip will perform roughly the same as each other. However, even though they use the same chip, some feature slightly higher clock speeds, as well as manufacturer guaranteed overclocking-an even higher clock speed than that specified. Other factors that will influence your decision should include the amount of memory a card has (128MB, 256MB, 512MB) and its additional features, such as TV-Out and dual-screen support.

How to Choose Between External Storage And Internal Storage Drives

The decision on whether to use an external storage drive versus an internal storage drive with your PC or device can be difficult. It is not just an aesthetic decision, but rather one that should be based on your needs versus the pros and cons of each type of drive.

The first thing you should consider when you begin looking for a new storage device is, no matter what kind will be whether you need an internal or external device. They each have their own sets of pros and cons, so it is important to be educated on each.

The first, and most obvious, benefit of an external hard drive is that it is easier to set up and get started with, especially if you are a computer novice. In most cases, it is a matter of simply plugging in the proper power source and USB cables, installing the proper drivers (which your computer will often lead you through), and you are ready to start using your external storage drive. This is really the best way to go if you are not confident or at all interested in messing around with the wires and cables inside your desktop or laptop.

A second, and perhaps less obvious benefit of the external memory drive, is that they are much easier to share between different users. Most of the USB/FireWire hard drives available today are "plug and play." This set up makes it simple to move the drive from one machine to another, since you simply unplug the drive from one machine and plug it into another. You can, then, more easily transfer files from home, to work, to school, or to a friend. The value of the convenience alone may be worth it to you, depending on your individual situation.

On the other hand, the downside of an external storage drive is that they are certainly slower than internal ones. Internal drives usually are connected to the computer through IDE/ATA busses, which are what support higher data transfer seeds than USB busses, which is how most external storage drives are connected. Also, in a simple manner of cost, since external drives generally have their own casings, they are often more expensive than internal drives.


As a general rule, internal drives are both faster and less expensive than their external counterparts. The biggest, perhaps most obvious, drawback of the internal storage devices is installing them. So, if you decide to go the internal route, look for a package that includes with it all of the cables and hardware required for installation. You will also want something that has a manual that is illustrated and easy for you to understand. In addition, good installation software can make or break it. If the package is a good one, even the most novice PC user will be able to install in internal drive.

Another advantage of internal storage drives is the price. As a rule, the greater the capacity of the media involved with the storage device, the cheaper the price per megabyte, but obviously the price is higher per device. Either way, since internal storage devices do not require their own casing, they run cheaper than their external counterparts.

The disadvantages to internal storage drives are more on par with their convenience. With most internal storage drives you lose the ease of user changing. You will have a much more difficult time removing an internal drive and transferring it to another person’s computer. Of course, if you are using a laptop, such convenience is a little less necessary.

There are obviously a number of factors to take into account when making the decision between internal or external storage solutions. You must figure out what kind of access speed you need, how much backup storage you will need, overall storage needs both now and in the future, how much security and privacy you need, and a number of other memory factors. The thing is that in the end, you will do fine whether you select an internal storage drive or an external storage drive. Storage devices are more affordable than ever with more space available than ever. So make an educated guess at what is best for you and go for it, you really can’t go wrong either way.
