Display of static images
The permanent display of a bright picture can lead to a burn in effect in the case
of a TFT LCD. Shadows of the previous image could remain on the screen even
changing the image. This is known as Temporary Image Retention (TIR) or Image
sticking.
TIR doesn’t affect LCD’s life or reliability.
The best way to avoid TIR is to limit the amount of static content on the display.
When this is not an option, you can use a screensaver to display moving images
(e.g. flying stars).
Display modes
The LCD has a fixed number of pixels so some video modes are supported in
expansion mode.
Expansion mode is a function to expand the screen size in different resolutions
(e.g. 800x600 on an 1024x768 LCD) so the image can be displayed almost fully
on the screen.
In Expansion mode the display quality can look not very good in some cases.
Faulty pixels in LCD
A minimum number of faulty pixels are permissible.
The production process for TFT LCD does not currently guarantee that all pixels in
the screen are error free. As long as it is not a case of an accumulation of locally
faulty pixels, there are not relevant functional restrictions.
LCD panel selection by Bios Setup
LCD panel selection is by Bios Setup on the “Advanced – Video Function
Configuration” menu.
