As with the asker of this question I have a monitor which suffers from terrible LCD Image Persistence problems. After a few hours, static elements on screen start to persist and in some areas of the screen (particularly at the top, where VMware Workstation positions tabs for switching VMs) I get brighter pixels bleeding up into darker areas.
The screen is a pretty old TFT screen which was very cheap when new, but is otherwise functioning fine, so I don't want to replace it quite yet.
Things I have tried so far:
- Leaving the screen on over night, with a blank screen screen saver.
- Leaving the screen on over night, with a screen saver that constantly rotates new patterns.
- Otherwise, I always turn the monitor off when not in use, but often the discolouration is visible first thing in the morning after having been switched off over night.
None of these things have helped with this monitor.
I do wonder, however, if anyone has come across a screen saver optimised for recovering badly image persisted screens. Perhaps by cycling through black/red/green/blue/white colour cycle patterns designed to free-up permanently imprinted crystals.
