How to Get the Best Quality of LCD Screen
Make sure that a display is adjusted to perform optimally, based on the manufacturer-recommended or default settings when possible. Ensure that your video card is set to the LCD Monitor's optimal resolution. Evidently, the most important tool (diagnostic equipment) to evaluate the quality of LCD screen is the human eye. Adjust the display settings on your computer so the brightness of the screen is about the same as your work environment. Also, adjust the screen settings to make sure the contrast between the screen background and the on-screen characters is high. And make sure that the text size is optimized for the most comfort. Use Control Panel > Display Settings > Advanced > Monitor and set up "Screen refresh rate" (frequency) to a maximum possible. According to the eye experts refresh rate should be 70 Hz or higher.
LCD screens often have trouble reproducing all of the levels of the grayscale (the range of grays between true black and true white). When producing a bright white image, many LCD screens oversaturate the grayscale: the lightest grays of the scale are lost in the white background. Oversaturation can also lead to loss of color range – a poor color reproduction of a LCD screen at the brightest end of the scale, closest to white. A color-tracking error occurs when the intensity of red, green, and blue (RGB) do not adjust identically with signal-level changes for LCD screen. This lack of balance between the RGB channels affects color as well as grayscale, but it is most easily identified as a shift in color within shades of gray.
Perfectly uniform backlighting across an LCD's entire display surface is difficult to achieve. It is not uncommon for an LCD to have bright or dim patches or subtler variations in color intensity, which give the appearance of shading across the screen, or variable color intensity on the LCD display. Additionally, using a dark screen is the easiest way to spot glare and reflection problems, both of which can have distracting effects when you are viewing an LCD screen.
LCD screens are vulnerable. Dead pixels can occur when the screen is damaged or pressure is put upon the screen. Unfortunately, few manufacturers replace screens with dead pixels under warranty. A cracked or broken LCD display is not repairable and requires a new LCD screen to be replaced. Luckily, it is easy to replace even if you are not a technical person. Since most computer's manufacturers charge too much, you may try to find third-party companies on the market that are selling LCD screens. Some places carry a large inventory of brand new LCD screens. If you are unable to find a particular model listed on the websites, you can call or email them.
