Quality Of An LCD Screen

The quality of an LCD screen depends primarily on:

Resolution
The native resolution is measured by the number of horizontal and vertical pixels that make up the LCD matrix of the display.

Response time
Response time is the amount of time in milliseconds (ms) it takes for a pixel to turn on and off. A high response time can cause motion blur in PC games and full motion video.

Brightness
The measure of how much light an LCD panel can produce is measured in candelas per meter squared

Dot Pitch
The distance between pixels, usually measured in millimeters. The smaller the pixel pitch, the sharper the image.

Contrast ratio
This is the measure of difference in light intensity between the brightest white and the darkest black. With a high contrast ratio should have better color representation than one with a lower contrast ratio.
