On request from a user on IRC, I wrote a tool that might help with stuck LCD (sub)pixels. It uses a similar approach to JScreenFix
, randomly alternating between full RGB on/off colors for each pixel. But as none of my units have a stuck pixel, I don't know if this tool is actually effective.
If you have a unit with a non-working subpixel, please run this application
for about 10 minutes and report here whether that fixed the issue or not.
