Yeah and thats the sickest part about it (with most TV's), especially for HTPC user.You can't watch blurays or PAL sources (50hz) @60hz without stutter ...RGB 4:4:4 support => 60hz24/50/50hz support => no 4:4:4 RGB
i have tested my Samsung D8090 Plasma and it works fine on the PC-Mode (naming input to "PC" oder "DVI-PC") and 60hz output!
Any chance to get Full RGB support with 50hz or 24hz on Samsung TV's? Here it only works @60hz which is pretty much useless for PAL-Sources or Blurays.
First test (PC output 0-255):
On my Samsung TV you have to choose between hdmi blacklevel normal (16-235) and low (0-255).
Samsung hdmi blacklevel "low" => clipping
Samsung hdmi blacklevel "normal" => no clipping
Second test (Samsung hdmi blacklevel "normal"):
PC output 0-255 and 16-235 makes no difference at all.
So I guess the Yamaha does something.
