Yes I've read GPU-72, yes I've use search, yes I check all TV settings, yes I've update everything I can, and yes it doesn't help.
I have LG TV (37LF75) and SAPPHIRE ATI 5770 videocard connected throu HDMI cable. I use Windows 8 x64 (release, not CP).
After installing OS windows and latest dirvers (12.8) picture like in GPU-72 appeared, but this issue was easy solved by changing Pixel format from YCbCr to RBG. So in Windows picture is perfect.
But when I run games (like WOW 5.0.4 or WOT 0.8.0) that use DirectX 11 black borders appear again. Sometimes, when I switch between game and OS, screen is not re-initialize and black border appears in Windows again, at this time I should go to the CCC and change pixel format to another and back and all is OK, black border is disappear.
When I connect my TV through old-school VGA cable image is bad quality but no black borders appear.
Then I've downloaded Microsoft DirectX SDK and compile and run their example (MultithreadedRendering11) and I have the same problem.
So it looks like no Pixel format options is applied when FullScreen game is initialized and I have no idea what the parameter can( or should) be initialized during DX11 initialization to solve this problem.
Also scaling scroller does not enabled in my Windows.
