Display darkens/lightens based on window color

[kmcoded]

I just put together my new computer last night and everything is working except for one issue with the display. When I view a dark window/background, my display darkens. When I view a light window/background the display brightens. My monitor is a 32 inch Vizio 1080p HDTV.

Parts installed:
I5-2500k
EVGA GeForce 460 1GB
G.Skill 4GB 1600
GIGABYTE GA-Z68A-D3H-B3
Antec 300 Illusion
Antec Earthwatts 500W
Windows 7 64bit

If anyone has any suggestions on what to try that would be great!

Thanks

Just a guess :

Have a look at the onscreen display of the tv . Look for a setting for dynamic contrast or brightness and turn it to OFF

Thank you so much. I ended up having to turn off about 4 advanced video settings. It works great now.
