I have ThinkPad T510 with nVidia nvs 3100M video card. several months ago, when I reinstalled windows and installed video card driver from lenovo update, I got strange problem: the system recognized video card model, identified and supported correctly max resolution, but the quality was poor, as soon as there was gradient color on the monitor, it looked distorted & like video card was working in 16 bit color mode, not 32 (you know all that "pixelized" squares when you work on 16 bit color mode) but it was working in 32 bit color mode. It also plays videos in very bad quality, with huge, "pixelized" squares.
Then I uninstalled driver, used windows update, which downloaded the driver & problem was gone. Yesterday I had to reinstall windows agan, but now the problem is that Lenovo update service, windows update service & nvidia site gives me the same driver (I guess it's newer version then I was using before that) and all three versions works with this terrible distorted image, pixelized image.
I tried to update bios, installed lenovo power manager, set all power settings to max productivity, tried older drivers from lenovo site & nvidia site but without any luck. I believe it's driver problem, not device, because BEFORE I install driver, in 800x600 mode, with generic driver, the image is crystal clear, without any distortions and squares on gradient areas of images, but as soon as I install driver the problems are here.
Does anyone had problem like this & does anyone has any idea?

What version of the nvidia gpu driver have you installed? The knowledge base states exactly your problem with version 220.127.116.1121
Perhaps it helps.

Thanks a lot! You saved my life! I had the exectly that bugy version of driver. It's strange that all sources (windows update, lenovo system update & nvidia site) had this version for download & not upgraded version.
Anyway thanks, 2 days of horror are over

You're very welcome.
Well, I've got that same driver version, but I did not recognize any distortions or something like that. I guess this error comes up by chance.
