[QUOTE="djphatic, post: 474179, member: 74406"] Out of interested what TV is your PC connected upto and are you going via a receiver? I have a Samsung Series 7 TV connected to an Onkyo 875 and then my PC. I find that when using drivers where pixel formatting is working I am able to select between Normal and Low HDMI Black Level on my TV when I choose Full RGB but with the other options this is disabled (probably because the TV has realised it is receiving a 16-235 signal). I find that when Full RGB is selected and hdmi black level is set at normal then I get a duller picture (grey blacks, not just limited to EVR) but when selecting low hdmi black level blacks appear black again. I have recently just built a new PC for my friend and it had an onboard nvidia 9400. When I selected 16-235 in the nvidia control panel and left it outputting RGB i found that blacks were grey but if I choose HDMI black level as low blacks would as black. If set the graphics card to output YBrCr 4:4:4 with 16-235 everything was fine with HDMI black level set at normal. Its all very strange and difficult to get my head around... [/QUOTE]
