Fixed-pixel displays are display technologies such as LCD and plasma that use an unfluctuating matrix of pixels with a set number of pixels in each row and column.[1][2] With such displays, adjusting (scaling) to different aspect ratios because of different input signals requires complex processing.[2][better source needed]

In contrast, CRT-based displays "paint" the screen with the required number of pixels horizontally and vertically. CRTs can be designed to more easily accommodate a wide range of inputs (VGA, XVGA, NTSC, HDTV, etc.).[citation needed]
