My T60 runs well for years and suddenly this afternoon after one restart, the display had problem. The whole screen display shifted up and became flat. also, the resolution beame like 800X600. my screen is 1400X1050. and the whole screen display like in front of a green fog. This issue remains after reboot.
I tried to connect my laptop to an external monitor, it works fine. So, my display card is good.
I tried to update the driver, change the display settings in bios and in windows, but it does not work.
This is a picture of the screen. Hope the image works.

Any ideas what is going on? Thank you very much.
