<< Don't get the Samsung 955DF! I got it and the first thing I noticed was the graininess on the left and right sides. The dot pitch is .21 (or .20?) in the middle but it gets noticeably grainy on the sides. I've replaced it once already thinking it was defective. Same problem with the replacement. I even went to Best Buy and their display monitor had the same graininess. Most people don't notice it right away, although I found it especially noticeable on white backgrounds. >>
I have the exact same problem with my Hitachi 721F. The sides just look horrible compared to the center. I believe the Samsung 955DF and Hitachi 721F are based on the same tube. I could be wrong though. Maybe I should just shrink the image to the size of a 17" monitor. I want to exchange it, but I am afraid they will al be like this.
