If an image is displayed long enough on my TFT screen, a "shadow" of it is still visible like a semitransparent overlay for some time. The longer it is shown, and the brighter the image, the longer the "burned in" image stays. This is under Linux. What is the cause if this?
- Could it be that the monitor is running at a non-native frequency (Hz)?
- If not, any other theories as to what could be the cause?
- How do I check which frequency my monitor is running?
- How do I change the frequency?
If it matters, I'm using Ubuntu 9.04 but the relevant settings are probably in some settings file of the X server.
Also, bonus points to anyone that knows if this phenomena has a name, would make it easier to search for info.
