LCD monitors

important to consider when shopping for LCD monitors include contrast ratio, brightness (or "nits"), perspective, and response time. Contrast ratio is related to differences in the comparison between the bright white appearance and values of the darkest black. A higher contrast ratio will from have truer colors with less "wash out." A higher contrast ratio will have more real colors with the "wash out" lower. Offering a lower standard for models generally 350:1. Many experts recommend a contrast ratio of 500:1 or better. Brightness, LCD monitor brighter than CRTs, giving consumers little reason to hunt for models, especially models brighter. Brightness is measured in nits, or one candela per square meter. Wherever the value of 250-300 nits are standard. If nits are much higher you may want to choose a way to adjust the brightness low. Angle of view is an important consideration especially if you plan to have some people see the LCD monitor at any given time. There are vertical and horizontal angle of vision specification, which refers to the degree you can deviate from the middle of the picture before it started to wash out. High contrast level is usually more on select because the point of view became more widespread. Many are recommending a minimum of 140 degree angle of view horizontally and 120 degrees vertical. More and wider angle, it's getting better. Response time, response is measured in milliseconds (ms) and refers to how long it takes pixels to turn from completely white to black and back again. Smaller value is the response time is faster and more desirable, especially for playing games or viewing videos. If the slow response time, "ghosting" or "trailing" can occur with fast-moving images, as Repaints the screen overlap. A maximum response time must be no more than 25ms for general use, and 17ms is better. Many gamers do not no reports ghosting in using the LCD monitor with a response time of 16ms or less.
  LCDs use electric power only one-third to one half the power istrik from CRT monitors. It is also much better on the eyes, using 90% less space, and only a few kilograms of weight. LCD monitors also emit much less radiation than a CRT monitor. This makes the LCD great choice for almost everyone, and ideal for people who work all day in front of the screen. Colors can be changed or moved to the outer boundary from the point of view, especially on the screen with a narrow angle of view and low contrast ratio. For this reason graphics professionals who require color consistency demands without seeing angle generally use CRT, LCD although it has dingkatkan in this case. 

By manipulating the orientation of the crystal through the proper electrical charge of varying degrees and voltage, the crystal acts like a small window, opening or closing in response to stimuli, allowing the degree of light that has passed through a specific pixel color to illuminate the screen, creating images.
  As LCD technology develops, different techniques to produce colors emerge. Active-matrix or TFT (thin film transistor) technology to produce colors and images as sharp as any CRT and is usually considered more superior than passive matrix technology.
