Default Why do my regular channels look terrible on my HDTV?

I just purchased my first HDTV. It is a 40" sceptre. The regular channels look terrible, 1-60, but the digital channels which I believe are in HD look great.
I understand why the HD ones would look better, but the regular channels look terrible. Worse than my old tube tv. Movies look great also.

Is there a way to fix this?

Same reason why a Ferrari would run like sh#t on 87 octane fuel.

It's looking for a HD signal (1080 or 720) and is receiving 480. Since an HDTV will always display it's native resolution of 1080(or 768, or 720, depending on the model), it has to fill in the missing resolution through processing. The better the processor, the better job it does upconverting the 480 signal.

It depends on the tv. Some do a much better job at upscaling the standard tv signal than others. It sounds like your doesn't do a very good job at that.

Movies look great also.
When you say movies look great, I'm assuming that you mean DVD movies.
They are also at 480, but obviously either your DVD player or your new TV is doing a fine job of upscaling them.
I'll also assume that you have cable service; since SD DVD looks great but SD TV looks terrible I'd guess that your cable service is compressing the hell out of the SD channels resulting in severe artifacts when you upscale to higher resolutions.

IF it's a result of heavy compression, there'll be no way to fix it.
BUT since just about all of your standard channels are probably replicated in HD the question is why would you want to "fix" it?

BTW there are about 50 threads on this topic already - no need to continue yet another one. Could a mod lock this perhaps?

Only 4 of our standard channels are replicated in HD. So that leaves 66 others that are not.

I have never heard of any cable company that does not provide more than 4 HD channels with even the most BASIC service . . .
could be though.

If that's the case, you may wish to consider upgrading your service to expanded basic in order to fix the problem.
