HDMI is better than component. HDMI offers digital quality, whereas component doesn't. On certain items you can see a difference. HDMI cables can be found cheap online. DVI is also superior, but those do not offer digital sound like HDMI.
HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. However, if your source is not in high definition, you will just get standard definition on your monitor and standard stereo on audio.
Again, depending on the source, you can see a difference.
Actually I imagine in a double blind test exactly 50% of the people could tell the difference. In other words, no one can tell the difference between an HDMi cable connection and a component cable connection if the both inputs are properly calibrated for the incoming HD data.
I agree that if the TV is properly calibrated you don't see any difference, although perception is a bigger part of the problem. What happens is a person, who knows little to nothing about what they are buying, goes in to buy a HDTV. The sales people sell them the $150 HDMI monster cable because "it will give them the best possible picture". So when the average Joe cable guy comes in and tries connecting the component cables the fight begins. Bottom line is I've seen the exact same brand and model of TV side by side with picture settings optimized and honestly couldn't tell the difference between the HDMI and component wired sets. side note to D. Weed~ HDMI does pass digital audio as well as the video, the "MI" in HDMI stands for multi-media interface. Multi being more then one = both audio and video, and it does have everything to do with the connection. DVI only passes video, component only passes video and both rely on the PCM left/right audio jumpers be connected in order to hear audio when viewing those inputs
Attach your DVD player to you HDTV via HDMI and run the tests....
Then remove the HDMI and attach component cables and run the tests again.
Let your eyes tell you... then tell us. Your answer could and probably will be different than mine... as your source DVD and destination HDTV will probably be different than mine.
The source (DVD) and destination (HDTV) should be left in the same setup as much as possible for each test.
You may find that many AVR receives "like" either a coax or optical audio input so that today, although the HDMI can carry both audio and video, the question is if the AVR should be the hub for video as well as audio.
Are you really performing a valid test with a 480p dvd vs. 1080i? There are too many times I hear about people saying "well I plugged my dvd into the input and everything worked just fine". You can't compare 480 to 1080 and expect similar results. Now if you've got a 1080i DVD player with a true 1080i formatted disc, be my guest and do a true comparisson, otherwise the test is invalid. don't compare apples to oranges, compare apples to apples.
