[QUOTE="kiwijunglist, post: 421885, member: 76888"] Be prepared to do a lot of reading it's all there if you click on some of the links that come of the avsforum post above. I would recommend you do the following test first Run Catalyst with default settings Adjust the TV brightness up really high. Run an HD movie and SD movie, see if the black of the movie is the black of the bars. If the black of the movie is the same as black bars in all content then everything is already setup. If the black of the movie is a different colour to the black bar then your PC is sending 0-255 but your renderer is rendering 16-235. Adjust the brightness of TV down until black of movie = black of the bar. Then load an SD movie, hopefully the black of the movie is the same as the black of the bar. Now adjust the brightness back up one or two notches - you should now notice a subtle difference between the black movie and black bars, adjust it back down so they are the same. Your black level is now sweet as =) ... with this setting you actually miss out on 0-16, but that doesn't matter as the video is never rendered below 16 so there is no point being able to view below 16.
