I have waited a couple of years now to buy an HDTV compatible RPTV. (Used to have Tosh 50" 4:3 RPTV) I always thought the greatest advantage of going to an HDTV compatible TV was that I could use progressive scanning from my DVD. Now I'm not so sure. With my new TV I still see scan lines at times (with an outdoor type scene showing sky or light blue) and the only difference between p and i is that the p lines are wider. i.e. there are fewer lines than interlaced. I am using a Pioneer 563a dvd player set to progressive scan output. The TV is set to "film" and I swich between 540p and 1080i for comparison. Although not calibrated I have set my brightness and contrast to low to mid 40's with sharpness the same. All processing features (SVM, ALS, flesh tone, etc are off), colour temp set to medium for now until I can get the set calibrated. ($430 here from the only place in town that is supposedly certified. Advance audio. ) Should I forget progessive output on the DVD player and set to interlaced and let the Tosh do the progressive at 540p or 1080i? Sorry if this is a dumb question and thanks in advance for any responses. J.
