Greetings! My mother purchased us an HDTV for our anniversary. It is a SANSUI 26" 16:9 8ms 720p LCD HDTV HDLCD2600. She has the same model and it looks good hooked up to her digital, non-HD cable. So, while it doesn't look as good as HDTV, it's way better than a regular tube TV, and way, way better than our TV at home, so I was pretty excited. I got mine home Saturday night and hooked it up to our digital, non-HD cable and my XBOX. Because I wasn't expecting to get the TV, I only had coaxial cable to hookup my cable to the TV. I used the component connector to get the XBOX hooked up to the TV. When I turn the TV on, it is in 480i rather than 720p. Our cable in some ways looks worse than it did before, and my XBOX, while it looks better than it did, still doesn't look as sharp as others I have seen. I've gone thru the manual to see if there is a setting I need to change to get 720p and the only reference I see to 720p relates to using HDMI to connect your cable to the TV. It's important to understand, too, that I know next to nothing about HDTV and HDTV service. From what little I do know, 720p should be find for me because I don't own a PS3, Blue-Ray or HD-DVD player. And, when the time does come to get HDTV service, most channels are broadcast in 720p anyways. That is pretty much the extent of what I know. So, now for the questions! 1. Should I be able to set my TV to 720p to correct some of the issues I am having? I understand because I don't have HDTV service that I won't get thru HD while watching TV, but it doesn't look as good as my mom's does. 2. How much does my choice of cabling affect my picture quality? Should I look at S-Video or Component to connect my cable-TV? And what about the XBOX? A friend of mine uses an HDMI connection from his XBOX to his TV and it looks great. I don't want to spend the money on that, however, until I can either get my TV to run in 720p or I know that my lack of such a cable is why my XOBX isn't as sharp as it could be. 3. Is there anything else I should know that I don't? Thanks!
