4.3.2 Colour Distortions on Monitors with Flat Screens (TFT Monitors)
If the display content on a TFT monitor has remained unchanged for a long period of time and is then
replaced by a different display, an effect can occur which is known as "ion spotting" in the case of
cathode ray tubes: the previous display is still faintly visible in the form of discoloration. In the case of
TFT monitors, in contrast to monitors with cathode ray tubes, this effect is reversible and therefore
cannot be regarded as a defect. If the monitor is operated for a long time (several hours or days) with
a different display, the discoloration disappears.
