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, the CRTs electronics architecture "paints" 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.).
