PC Connected to HDTV, appears blocky and pixelated when running a game fullscreen

[JibbaJabba]

Yesterday my old monitor finally died, so I temporarily have my 32' Sony Bravia connected to it. I re-calibrated the Win 7 color settings and the TV using http://www.lagom.nl/lcd-test/ and everything looks great until I start a game, at which point everything becomes pixelated. The games still look ok, if a bit jaggy, but small text is unreadable. For instance, the Steam overlay is a pixelated mess, I can't read what I type into Google, and I cant read the Steam FPS counter when a game is running.

I've tried messing with settings in the TV, re-doing the WIN 7 settings and looked through the Nvidia control panel but I can't figure out whats causing it. So far all I've discovered is that the screen only shifts when I play a game fullscreen. If I switch to borderless windowed fullscreen (if a game supports it) everything looks fine again.

My TV does not have any PC specific settings unless I use an old VGA cable...yeah right. They are greyed out when connected via HDMI as I am.

Anyone ever see something like this?

Make sure the game is set to the proper resolution.

All games are set to the native resolution, 1920x1080.

SOLUTION FOUND!

In the Nvidia Control Panel, Display > Adjust Desktop Color Settings, at the bottom of the window there is a dropdown labeled "Content type reported to the display". Change the value from "Auto-select" to "desktop programs" and fullscreen games will look crisp and text is readable.

Awesome! Glad you found that!
