    If your digital cable box has an active DVI connection, that's what I would (and do) use. I don't know of a cable box that uses HDMI connections yet....which doesn't mean that they're not out there somewhere.

    Correct...DVI is video only and HDMI is both audio and video. If your display has an HDMI interface and your cable box DVI, then you'll need a cable with one type at each end and it will pass video only. My cable company gave me the cable when I ordered the box but a decent quality 6' DVI/DVI or DVI/HDMI cable should be well under fifty bucks. Check out the forum sponser Ram Electronics. No need for the "high end" or high price spread IMO.

    I had the same basic questions when I purchased my new tv a few months ago. I would say the best thing to do is to try all of the connections and decide which one is best. It will vary from system to system. I used HDMI on my Directv box and I found the the comp output was just as good, at least on my set and to my eyes anyway. I think it depends on which unit has the best conversion section. In my case it was the tv so comp inputs were just fine.

    since you have a fixed pixel display, a digital connection should reap some kind of benefit. they say on analog display device, there is less of a benefit from a digital. however, i ran digital to my 65" crt rptv and noticed a slight improvement.

    overall, i agree with dan. try them out and see if you notice a difference. if not, go with the cheapest solution. [​IMG]

    Not so. Implementation varies, I've seen inputs on digital displays where the YPbPr was superior to DVI. I've reached the conclusion that there is no prediction you can make about what connection you can use. Devices, especially consumer devices, use crappy implementations of signal types all the time, so while in theory maintaining a digital signal may seem easier, in practice it's certainly not always the case. Further, if both are done fully well, they should be indistinguishible in most all cases.

    $25 is too much for a DVI or HDMI cable!
