I brought a Radeon 7770 recently. According to its description, it should be able to output deep color to HDMI. However I can not figure it out. I read AMD's document about 10-bit color (probably out-dated) and it says only FirePro is able to output 10-bit color with such setting turned on in Catalyst Control Center. I did not find such setting in Catalyst Control Center. Could I ask if anyone was able to get deep color working on a Radeon card?
