Hi, I have a LG LM6200, on my PS3 i set RGB to limited (16-235) also on the TV the black levels are set to low, but I can still see 0-255.. what does this mean? 0-16 it's supposed to look black right? so I turned down the brightness on the TV ...am I clipping black? is this ok? also watch movies on my PS3 so I'm not sure if change it to RGB to full.. or does this option only affect games? Thanks in avanced......
