Better for watching DVD--iPad 2 or iPad 3?

Does a dvd look better on a standard def tv or on an HDTV? Same concept.

The dvd will have to spread the picture over more pixels to fit the screen, so it will look more pixellated than if it was an HD video.

For a 10" screen, the results might not be as drastic as it is with a full sized TV, but I'm sure it would still be pretty noticeable.

I don't have videos encoded from dvds on my ipad but I do have some standard def tv shows from the itunes store @ 640x480 resolution and it looks pixellated on the ipad.

I have ipad1 btw same res as ipad2.

Right now, the iPad 2 is infinitely better because the iPad 3 does not exist.

Until it is at least announced, let alone released, nobody can tell you what it will be better or worse for because nobody knows exactly what it will have.

iPad 4.

Agreed.

Well we don't even know if the iPad 3 will have a retina display, but if it did, the answer is no.

480p video on a 480p screen will look exactly the same as on a 1080p display. Why? Because the pixels are still there, the 1080p screen just has to fake them. If anything, the 480p video will look better on the 480p screen because the pixels will match and it will look crisper.

If you watch a HD video on a HD screen, then of course it would look better than SD on an HD screen.

Either I'm missing the point or your question was incredibly basic and you are lacking a thing called logic.

But you didn't present a speculative question, you asked a question of a factual nature. At least that's how it was presented.

Given that 480p video needs to be scaled either way, it's unlikely you would perceive any difference in sharpness between 1024x768 and higher resolution screens when playing back DVDs. You may notice the reduced screen door effect, though.

You asked as though you were actually looking for information to base a buying decision off of. Any info you get from this thread IS pure speculation and should NOT be used to make actual decisions.

And there is already a thread for speculating about video problems on the iPad 3/retina display:

https://forums.macrumors.com/threads/1304441/

Which was easily found by searching the forum for DVD.

Assuming that iPad 3 has the rumored hi-res display, the DVDs will look exactly the same or little better, for the simple fact that doubling both horizontal AND vertical pixel count EXACTLY two times on a SAME size display will mean that a single old pixel will be EXACTLY the same size as 4 new pixels. So a simple way to ensure same quality would be to do just that. A more sophisticated algorithm can use the fact that the pixel can now be divided into 4, and can truly upscale the picture.

Don't know why everyone downvotes this, since it's a perfectly legitimate question. IF the iPad 3 has a retina display, will SD content look fuzzier on it than on the lower-res iPad 1/2? This is a perfectly reasonable question, since we all know that SD content looks better on old TVs than on new HDTVs. Wouldn't the same be true here? If not, please explain why without being obnoxious or insulting (otherwise just refrain from commenting).

SD picture on an HD looks worse than on an old TV for two reasons - the count of pixels isn't an exact multiple in any direction, and everything is much larger.

This means that an HDTV must display a picture that has 720x480 pixels on 1920x1080 resolution screen. That's 2.66 HD pixels horizontally and 2.25 HD pixels vertically for each SD pixel. This mean that the upconverter has to take each SD pixel and somehow paint it over that 2.66 x 2.25 area. Obviously that doesn't translate evenly and hence the reason for the image quality, and the importance of good upconverter.

As if this wasn't bad enough, modern TVs are much larger than the old counterparts, so not only do we have the issue above, but we now magnify it physically by having you stare at the imperfect translation of the SD pixel in a physically larger area than that SD pixel was before.

I hope this explanation makes sense, and shows why, with iPad 3 having an exact multiple of pixels in each directions and same screen size should look the same at the very worst, and better with any decent upconverter logic.

...and in both cases it depends on the scaling used. Not all methods are equal despite your broad, sweeping generalization. My Bluray player does an excellent job of upscaling SD DVD's. They're certainly not comparable to Bluray by any means but your assertion is false. You're assuming that what you've experienced is all there is out there.

Again, you're confusing "know" with "assume". Not all SD content looks better on SDTV's than it does on HDTV's. Again, it depends on the specific source and upscaling used and not all upscaling is equal.


All that said, I wouldn't expect the iPad 3 to have the same quality of upscaling as my Bluray player but we'll just have to see. Anything posted until someone has first hand experience is just pointless speculation.

I don't know what else I can do besides drawing pictures, and I don't have the time, but please re-read my post above. This is not an opinion, or a subjective take on something. This is a mathematical truth - when you take a 1x1 area (single pixel) and change it into a 2x2 area (4 pixels) in the SAME physical size, there is NO degradation in quality by default. If that SD pixel was red, and you make the 4 HD pixels red, there is NO difference in the picture. The SAME PHYSICAL area on the screen is red.

iPads don't play HD video, do they?

Surprised that no one's mentioned viewing distance as a factor yet (at least I didn't see it) but look up viewing distance in relation to resolution you'll likely get a lot of results comparing 720 to 1080 TVs but the same concept applies. Basically as distance increases our human eyes are only able to resolve so much detail despite what it might be output at.

You'd probably notice a difference at Arms length, but if you are setting it up on a table 5-6 feet in front of you then maybe not.

the problem some people seem to be having is that the question was iPad 2 or 3, yes the image may look better on a SD TV than on either iPad, but because the iPad 3's (supposed) retina display will be exactly double the resolution of the iPad 2, there will be no difference between the two when viewing lower resolution videos, because as others have said, what would use 1 pixel on the iPad 2, just uses 4 on the iPad 3 which takes up the same space.

Better for watching DVD--iPad 2 or iPad 3?

As apple said, the iPad 3 stands for the higher-resolution Retina display, which would have double the linear resolution of the current iPad 2 screen. Watching DVD on the new iPad will give you a more colorful effects.
