I have an HP Pavilion dv6 too - I came across your post (and Viki's "help") because my contrast was all out of whack, too (way too bright). Adjusting the gamma did nothing - but then I unplugged the power cord from the laptop, waited a second, and plugged it back in, and voila! It's all good now. Not sure why...
There's also this thread on changing colour settings - I haven't tried what they said, but may come in handy...

I too had a annoying contrast issue that seems to have been affecting other users. I have an HP Pavilion DV6, 6Gb RAM, with AMD Radeon 6620G/3520M APU.
Essentially - the screen contrast & colors were OK when plugged, but on battery it looked all washed out and just wansn't right.
I solved it by finding a little setting in the AMD Vision Engine Control Center (AMD video) settings. So I right-clicked on the desktop in Win7, selected the AMD Vision thingy, then, in the Power section, clicked PowerPlay, then unchecked the box marked Enable Vari-Bright. This immediately solved the problem and the contrast is the same now on battery or power.

YOU are a savior!!! I couldn't even see the "cherry blossom" background of my gmail with that enabled. This is fantastic!
But honestly, what is the point of that option? Just makes things invisible.

This is definitely a fix most of the time . fixed my issue when i was playing a game and for some reason the dark areas would be extremely dark . I was always knew it was the varibright option but I didnt listen to my gut feeling. Thanks
