You probably get this question alot, but I cannot find any solid information after several hours of research so I thought I'd post my experience/questions and get opinions on my setup. Basically I want to know what RGB color space I should be using at each point in my HTPC chain.
1. GTX680 (310.90 beta drivers) -> Denon AVR-2809CI via HDMI
2. Denon AVR-2809CI -> Pioneer KRP-500M via HDMI
3. Media player is PotPlayer using LAVFilters + LAV Video + MadVR
Here's how I've had it set up for as long as I can remember: RGB Full is being output by the graphic card thanks to the RGB registry fix. The TV is set to RGB Full. And finally, MadVR is also set to RGB Full. So RGB Full at all points in my chain results in the correct black level.
However, setting both the TV and MadVR to RGB Limited results in almost the exact same black level. I say almost because Limited results in an extremely slight increase in black level. But for all intents and purposes it's exactly the same. Finally, setting the graphic card's output to RGB Limited, the TV to Limited, and MadVR to Full also results in the correct black level.
Does this sound correct? If it is, could someone explain how and why all of these settings work? I'd really like to wrap my head around this and understand it. If it's not correct, then I'm guessing there's something else in the chain affecting things. I tried messing with my receivers HDMI settings, but it resulted in no change. Same for LAVFilters/LAV Video settings.
