IM thinking about getting the new Samsung DLP, 43 inch hln series soon to be released. Can anybody inform me how isf calibration will be done on dlp? 1. do you have to refocus dlp? like crt. 2. is there any new geometry problems or is that a thing of the past? 3. Does it still need color calibration? and do you have to adjust the grey scale on every input or just one? 4. can I line the tv with felt to stop reflections? Just a few questions there to keep you going. Carl.
