I just got the samsung tantus hdtv direct view tv and while the overall picture is very impressive the screen geometry is not quite perfect. Any horizontal line through the bottom half of the screen is slighly bend upwards in the middle. This defect is probably within factory tolerance but still annoying to me and I was wondering if there is a way to fix this. I did some searches on this forum and it sounds like isf calibraters will not fix geomtry problems on a direct view tv. So is there nothing i can do other than go through another set and potentially end up with the same issue?
