One of the most prominent features of a computer is its monitor. Monitors are the basic requirement for any PC. The sizes of computer monitors vary, of course, according to choice and requirements. The standard size of all monitors is between 14 to 17 inches. It is a peripheral device that is used for viewing video output.
When initially introduced, computer monitors were much like cathode ray television screens ? big, bulky and ugly. Now however, as times have changed, monitors have evolved into sleek LCD screens. They are also no longer black and white, but show images in thousands of bright, vivid colors. Essentially, a monitor only uses combinations of 4 to 16 colors, including red, green, cyan and yellow. Modern monitors also support LVDS and TMDS protocols. Another advantage with LCD screens is that an image looks the same from all angles, while in a cathode ray monitor one can view an image only when one's facing the screen.
The working of a computer monitor is quite fascinating. Computers control a video card that is used to format the output to make it appropriately compatible for a computer monitor. This, in turn, displays alphanumeric text characters and symbols such as icons, graphics such as images and video that are comprehensible to the human eye.
LCD monitors are the preferred choice among best computer monitors today. This is because they are able to give a brighter, clearer picture and are not as harmful to the eyes as a rounded screen. They have an inherent misregistration of color planes that leads to subpixeling. A lot of renowned computer manufacturers are incorporation this technology including Apple, Microsoft and XFree86. LCD monitors are digital, which means better and clearer picture quality, so your images will be clearer and your work flow will be smoother and faster.
When you buy a PC, you get a as part of the package. But if you're looking to assemble your computer, you can include any monitor of your choice. There are plenty of options available, from , to Hewlett Packard to Compaq ? all better than each other.
The good news is that the best computer monitors can now be bought online as well. Many popular online shopping portals offer low price computer monitors from different companies, in every size. You can compare prices and buy computer monitors from a good store and make your PC worthwhile and comfortable to work with.
Contrast, clarity and overall image quality are the key things to consider. This article will introduce you to these concepts in more detail, and discuss some of the ideal specs.
Computer Monitors ? Basic Considerations
At one time, this discussion would have included an overview of the merits of cathode ray tube (CRT) monitors versus LCD. LCD monitors are now the norm so that argument has fallen by the wayside. In addition to the hard numbers about computer monitors, there are some other basic factors for businesspeople to consider.
? Your Office Environment. Do you have a large window that causes a lot of glare on your screen? Is your office dark? Both of these questions will affect your decision on a monitor. To combat glare, you may need to angle your monitor, so you should find one that is adjustable. For dim lighting, be sure the monitor you choose has an adequate brightness rating.
? How You Work. Do you frequently work with several applications at a time? If so, you may want a larger screen so you don't have to constantly flip between active applications.
Just the Facts ? Computer Monitor Specifications
Here are some of the monitor specs you need to know about.
First, there is the response rate. Some tech experts call this number a marketing gimmick. In theory, lower response rates mean less distortion in a moving image. The rate itself is a measure of how long it takes a pixel to go from black to white and back again. While it is probably more important for users who watch a lot of video, this rating can indicate the quality of the image you will see. The ?marketing gimmick? aspect is important here. Most manufacturers list the lowest response rate, which is not necessarily the average response rate. Chances are the rate will be higher than the one listed. Response time is measured in milliseconds (ms). If the monitor has specs of 8 to 12 ms or lower, it is usually fine.
Second, is the native resolution. Computer monitors can be adjusted for different resolutions, but the native resolution is the optimal one. Higher resolutions generally mean better image quality.
Third, is the brightness. Brightness ratings indicate how much light the monitor can generate. Brightness is also referred to as luminance. It is measured in candelas per square meter. Most experts will tell you that a rating of about 200-250 cd/m2 is best for work. Higher brightness ratings are okay too, but probably not necessary for a work environment.
Lastly, there is the contrast ratio. This number tells you how bright the whites are and how dark the blacks are. The higher the number, the better the contrast. It used to be that a contrast ratio of 800:1 or 1,000:1 was considered adequate ? and it still is - but now even low-priced computer monitors have specs of 5,000:1 or greater.
When shopping, keep in mind that many companies regularly upgrade their computer monitors when something new hits the market. As a result, there are great deals to be had on the secondary market.
