I have a Samsung TSL2793HF, a 4:3 ratio 27" CRT HDTV. I noticed that with widescreen movies, the black bars on top and bottom were not straight - they curved up at the sides of the screen along the top of the picture, and down along the bottom. I went into the service menu to try to make some changes and nothing seemed to help. I ended up just doing a Reset thinking the initial settings would be better, but boy that was a mistake. The geometry is going to be trial and error I suppose, and I'll be smarter about it this time. I was just wondering if anyone had any idea what settings I should test to try to fix the screen curving towards the corners. The reset also brought up another problem. There's a very noticeable white shimmer on the screen if the contrast is too high. The default setting for the TV is 100% on contrast. I can make the shimmer go away by lowering the contrast to around 70% - but the fact that the default is 100 and that produces a very odd shimmer troubles me. Is this normal?
