Default Does Blu-ray even matter on a 720 tv

I have an Aquos 42" 720 and im wondering if blu-ray will look any better than a dvd on that tv?

I've got a 720p 42 inch and yes indeed, it makes a difference.

Not the 1st time this question has been asked....

Are you one of those people who buy an HDTV but just have SD programming?

If so, maybe I can understand the question (but not your reasoning).

Otherwise you should already have an idea of how much better it is going to look (and Blu Ray will look even better than HD broadcast/subscription programming in many cases).

considering DVD is 480i, which at any given instant is only 240 lines of resolution, BD offers three times the resolution when viewed on a 720 set. In fact, depending on how far you sit from the screen, 720 and 1080 might not look any different. The bigger difference is going from standard def to high def.

its not just resolution. BDs tend to have less edge enhancement and other crappy dvd artifacts. less filtering as well which in turns gives a nice detailed image.
Even with a 720p set your still just upscaling dvd. better to downscale 1080p than upscale 480i/576i imho

well thats just incorrect. Unless you mean the first DVD's from way back in 96/97 that were actually encoded as interlaced MPEG-2 Streams.

All DVD's are encoded at the NTSC standard frame size 720x480 [progressive]. And technically you are still getting a 'progressive' picture even via 480i composite cables, only spread across a 60i signal.

Only difference is you are not seeing the full image at the same time.. but your eyes and brain take care of that. Persistent image comes to mind.

Not really. It's actually the player (assuming it outputs 480p or higher) or display (the OP has a Sharp LCD) that's converting interlaced back to progressive. Persistence of vision inly comes to play when you feed an interlaced signal to an interlaced TV (e.g., 1080/60i OTA broadcast into a CRT HDTV).

But your point is valid, DVDs is 720x480 and Blu-ray is 1920x1080. The OP's TV is either 1366x768 or 1280x720, which means there is at least twice as many pixels than DVD can offer.

And of course Blu-ray has much less compression artifacts due to the higher bandwidth.

Don't let a 720p set hold you back. It is still 3x over 480p. CK to be sure that the Blu ray payer does a good job at down-converting 1080p to 720p, otherwise send it as 1080i.

Newer 720p sets can handshake with 1080p.

Screen Size/Distance/Resolution. You should sit at the proper distance from your set.

Composite video reduces DVD to NTSC which must pass through the comb or Y/C filter decoder in your set. I believe the best case is 240 lines per picture height.

With 480i, vertical resolution can go down to 240 lines when there is motion in the image because the fields may not line up. DVD's 480p on a progressive set can be 2x over 480i. Just look at the scrolling end credits of a movie to see the difference between 480i and 480p.

NTSC Encoding/Decoding.

Me too. I have Sharp Aquos 32" 720P and currently watching "Lost"
and the beach scenes was just breath taking. I can't imagine what it will look like on 1080P.
