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.).[citation needed]

A fixed pixel display is characterised by the number of rows and columns that can be addressed. This can be referred to as the 'native resolution' of the panel. When the native resolution of the panel matches the resolution of the signal it can be used directly. When the signal does not match this resolution some other measures must be taken to display the information. The most popular technique is resizing the signal electronically to match the resolution of the panel.
