Fixed-pixel display

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]}

Fixed vs. CRT pixels

Closeup of a fixed pixel display: pixels consist of 3 colored subpixels, and are arranged in a matrix, aligned both horizontally and vertically.

A CRT monitor that has no clear distinction of individual pixels; the image is formed based on the resolution set by the electron gun.

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.).^{[citation needed]}
