I have a Nec 1040 projector and its supposed to be progresive scan, but when i bought my new sony dvd player with progressive scan the picture is great but the upper part of the screen seems to be a little curvy, not really noticeble only when lines are going up there but still can see them, anyone had a problem with this? Its just the upper of the screen the rest is great. when off mode for progresive it works fine. Any help would be appreciated it.
