You have a set that has a native resolution that is 720P. Everything you pump into it will be scaled to 720p. So, if you want to get the full potential of your DVD player (only if you are playing a high def DVD) you will need a 1080p set (xxxx X 1080). Will you see a difference? Probably not much, ask Stewart. In any case, your high def DVDs will look better on either set than the standard DVDs.
I have a Samsung HP-S4253, a 42-inch Plasma HDTV. I believe its native resolution is 1024x768.
Its display capabilities include 480i/480p/720p/1080i.
I have hooked it up to a multi-directional HDTV antenna (DB4 from antennasdirect.com), to receive OTA HD broadcasts. NBC-HD (e.g. Deal or No Deal) and FOX-HD (e.g. Football) that are broadcast in 1080i just look awesome! So I know that my HDTV can display a 1080i source and one can really tell that from the picture quality.... Fox Football in fact looks like 3-D. There is that WOW factor!
Ok, now I recently bought the new HD-DVD player by Toshiba - HD-A2.
I have hooked it up to my HDTV via Monster M series HDMI cable. The player is set to output 1080i source. I have played quite a few HD-DVDs (recorded in 1080p), on this player and displayed on my HDTV. However, I do not see the WOW factor! The picture quality is good, but when compared to the OTA HD broadcasts, I really do not see the HD quality that I have seen in store demos.
I tried outputting 720p to the HDTV, still no difference.
What am I missing?
I did some research and found that a 1080p source's output resolution is 1920x1080, whereas a 720p source's output resolution is 1280x720. So if I output either of these 2 sources to my HDTV, whose resolution is 1024x768, I lose the Source's HD quality due to scaling - downward or upward - both horizontally & vertically.
So does that mean that in order to get true HD quality from my HD-DVD player, I need to change my HDTV display to something whose native resolution is either 1920x1080 OR 1280x720?
I hope you think this is not a trivial question, and I hope I get some meaningful answers.
