I'm not sure, but I think this comes down to how the TV itself scales the signal. Is there a menu option on your set to choose whether the TV is using 'Progressive" display? Or, is there a setting to choose whether your set of DVD player does the scaling? Or, a setting for "Video" or "Film" mode? Try changing all to see if anything changes. A friend of a friend just bought a 60" DLP set and he has the same problem. Regular standard-def signals are unwatchable, but HD signals look brilliant. I have an older rear projection Toshiba TV, and it's rated as 540p, not the typical 720p or 1080i. Someone told me that Toshiba did that specifically to make it an even multiple of HD resolution upscaling while making it an even multiple of SD downscaling. I don't know all the details, but my old set (50") makes regular cable look great, and HD looks terriffic too. I've seen some new TV resolutions stated at being something like 1024X768. To me, that's a resolution for a VGA computer monitor, but I've seen this resolution listed on 40", 50" and 60" TV's. On some rare sets listed as being 1920X1080 (true HD resolution), they cost $10 grand and up.
I just purchased a new LCD TV 32", and the normal Charter digital cable doesn't look all that hot. Is the TV just pointing out the flaws now that I'm not watching it on my old fish bowl TV anymore? Is there anything I can do to improve the picture? Thanks.
