Computer 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 Resolution

Similar to their predecessors, LCD computer monitors are measured diagonally to get the panel size. The ratio of the horizontal over the vertical dimensions is known as the screen aspect ratio. Ratios for standard monitors are 4:3 while widescreen monitors are 16:9 or 16:10. The 16:9 usually has the same viewing size as a 4:3 while screens with a 16:10 ration has black tabs on the top and bottom, which are obvious when viewing videos. Besides watching DVDs and blu-ray discs, having a larger screen is advantageous in opening several documents alongside one another as well as editing images. For the more casual Internet surfer, smaller screens will suffice.

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

When purchasing LCD computer monitors, there are a few factors to be considered. First, consider the intended function of the monitor to be purchased. When doing detailed work or watching high-resolution videos, widescreen monitors are better. For other purposes, smaller LCD monitors will suffice.

For a greater chance of compatibility between the users, the monitor and its use, try to test the monitor before buying. Try to see if the monitor feels comfortable and works well for the purpose intended. Do the necessary research before deciding to purchase. A monitor is a vital part of a computer and is a lasting investment for the user. - 31403
