LCD Monitors

By Miles Stoppard

LCD computer monitors are the modern development in display monitors. These have succeeded the cathode ray tube (CRT) monitors, which were identifiable by their bulky size. With their flat design, LCD computer monitors are lighter and consume less electricity. The technology in these more recent models provide better picture quality, greater detail with fewer distortions. Going for the widescreen models enables the PC to function as well as a home entertainment system.

Screen Size and Resolutions

In order to obtain the size of a monitor, the ratio between the crosswise and lengthwise measurements of the monitor is taken. This is the similar method for all types of computer monitors. For monitors' inches and under, the ratio is 4:3 while 22-inch widescreen monitors are 16:9 or 16:10. Viewing movies with LCD computer monitors having 4:3 or 16:9 ratios will be similar while in 16:10 widescreen monitors, black strips will be evident at the top and bottom parts of the video. Widescreen LCD computer monitors are beneficial for those who like to multitask and require seeing and working with greater image detail.

Depending on the size, computer monitors can come in a variety of resolutions from the smallest 1024x768, 1280x1040,-66x768,--40x900, 1600x900, 1680x1050,'20x1080, to the largest'20x1200. LCD computer monitors have screens that are comprised of millions of pixels. Known as dead pixels, these are pixels that emit black or a single color. Depending on the brand, dead pixels are usually less than or around ten pixels for every million. The number of dead pixels allowed for each manufacturer is given a rating ranging from Class I to Class IV, the highest being Class I.

Style and settings

LCD computer monitors have programmable options that allow the user to alter the settings. Similar to the old CRT monitors, there are buttons around the edge of the screen on the front, back or side of the screen. Depending on the brand and manufacturer, LCD monitors can come in a wide variety of colors from the simple, black or silver to more colorful designs consisting of stripes. Screen finishes can be matte or reflective. The finish can affect the amount of glare reflected as well as how the images appear.

Choosing the right monitor

In selecting the right LCD monitor, it is essential to consider the needs of the user. Its function must be determined, whether for work or leisure, for editing or watching videos. For the standard user, smaller screens will be sufficient for everyday uses. When performing work that requires image accuracy or when viewing movies in DVDs or Bluray discs, widescreen LCD computer monitors are a requisite. Image quality is also essential. How the monitor accurately presents the image should be carefully noted. When necessary, adjustments may be needed. As such, the buttons must be within reach of the user and easily identifiable.

As LCD computer monitors are more advanced than its CRT predecessor, picture quality is better but is still an important factor to be considered. The monitor should be user-friendly as well. More important when watching DVDs or editing images, the monitor should also have quick response times, as well as the ability to produce and reproduce more accurate colors and images. Buttons should be easily accessible for the necessary adjustments. When given the chance, test the monitor before purchasing. This increases the chance of compatibility between the user, the monitor and the intended function. - 30432
