Repairing “pressure marks” on an lcd in software

Locked

I just put a nasty pressure mark on my laptop’s screen, and am acutely depressed at the moment…. After searching around, it seems to be generaly accepted that they cannot be repaired in any way so I will have to replace my screen.

But, I was thinking, the pixels are *brighter* than their surrounding pixels, so it must be possible to at least reduce the symptoms by just dimming those pixels down, dividing their brightness by a certain factor. Maybe by modifying the video card driver somehow. Has anyone done this ? How can I try it? How can I modify a video card driver to do something like that?

1. Turn off your computer.
2. Get yourself a damp cloth, so that you don’t scratch your screen.
3. Apply pressure to the area where the dead pixel is. Do not put pressure anywhere else, as this may make more dead pixels.
4. While applying pressure, turn on your computer and screen.
5. Remove pressure and the dead pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through which give off different colours.

I’m talking about pressure marks, not dead pixels

Pressure marks are different from dead pixels. They are the result of something pressing on the back of the screen, thus damaging the extraction filter and making the affected pixels brighter. So nobody can even fathom what I’m talking about here??

Yes – I understand

but most have other things to worry about than one LCD screen. The filter is damaged (hence brighter) so this is a hardware fault and requires a hardware fix.
