Resolution and Interpolation
As opposed to CRT monitors, LC displays consist of a fixed pixel structure, which can not be altered and corresponds to the so called native resolution of an LCD.
The native resolution of 17 and 19 inch displays is 1280 x 1024, and that of 20 and 21 inch displays is 1600 x 1200. Displays that are even bigger at sizes of 23 or 24 inches are mostly widescreen LCDs in 16:9 format whose native resolution is 1920 x 1200 pixels. LCD monitors are incapable of depicting resolutions higher than their respective native resolution!
Only if the device is set to use its native resolution, the picture’s quality can live up to its potential. In case of the graphics card being too weak for this high resolution or if a specific game title doesn’t support the native resolution, the display needs to recalculate the smaller resolution to the larger screen area using a designated chip in order to show the content full-screen. This process is called interpolation, and the smaller of a resolution is chosen compared to the native resolution, the more it results in the picture loosing focus. For this reason, we recommend to always use a display’s native resolution.
In order to avoid interpolation, with some displays you are given the possibility to select an aspect true mode for lower resolutions via the On Screen Display (OSD, menu). The chosen resolution is then displayed pixel by pixel in its original format with black bars at the sides and/or at the top/bottom of the picture.
With displays that don’t offer aspect true or 1:1 display modes, one can still mostly set it by software, namely using the driver menu of the graphics card. In this case, the display needs to have a DVI input.
