Has anyone found the trick to get Intel HD Graphics 3000 (on a SandyBridge 2500K) to output full range RGB to a full range capable digital television?
With my TV, it is impossible to get the iGPU to output Full range RGB. Both "Full" and "Limited" settings look the same, flat washed out. I tried connecting both directly to the TV and via the my Onkyo TX-SR605.
Then I went back to my ATI card, changed it from Full to Limited RGB, and the colors there now looked just as flat and washed out as the iGPU always outputs. My TV is a Samsung DLP 50A650.
I have also tried the various tricks found in this thread on avsforum, incl. downgrading to driver version 2509, but nothing works.
It is strange Intel can't fix such a serious quality problem, which ATI, NVIDIA, Sony(PS3) and Microsoft(Xbox360) all nailed down years ago (by providing a working Full range option). I have had to use a discrete ATI card to get decent colors, while the otherwise high quality Intel GPU should be perfectly capable of providing this.
