I bought the Samsung DLP 50" when they first came out. When watching DVD's I noticed that movies are somewhat dark. There is very little room for adjustment in the contrast which goes from 0 to 100. If i go below 85 the picture is really to dark to enjoy. Is this somewhat due to the first generation chip? Also, Does the PC mode in the menu have to be set to any specific numbers. I find that even with no PC hooked up, they are still adjustable. COuld this cause the problem to the contrast? The TV owners manual is no HELP.
