All of my TV's receive a nasty, grainy, 8bit crap, looking image! I hook my MacBook Pro via HDMI and every time it looks like the screenshot attached! I used to notice this issue as it would show for like 0.5second until something auto adjusted but its annoying now...Quick time has no problem like this...but I hate quick time and I can't use it for Mkv's. Any advise? Thanks in advance....
