can tegra 3 output [email protected] via hdmi? - Asus Eee Pad Transformer Prime

Hello!
I'm asking the same question in all forums for tegra 3 devices cause I can't find any information using google.
Has anyone when connecting the prime via hdmi gotten 1080 with 24hz on your tv/display/projector/whatnot, not only 60 or 50hz?
I want to know if the Tegra 3 chip can output that kind of signal so you can get true 24p when watching movies.

I have not tested it myself, but my understanding is that the Prime will output 1080P video via the HDMI connection, as long as the video is on the Prime or SD card. I would assume that you'd be able to get higher frame rates if your video file and player supported it, but I would also have to think that a 240hz, (I assume you mean 240hz, as 24hz is way low) 1080P video file would be absolutely massive once it's stretched out to a full movie length. I remember the early demo videos for the Tegra 3 showed it playing (I believe) a 4K video loop via HDMI.

Thanks for answering! I mean 24hz not 240. 24hz is the standard for movies (24fps) and modern tv's and projectors must be able to receive a 24hz (or anything dividable with 24) signal for perfect playback. I guess you're not that familiar with video standards, but anyhow, if you watch a movie with 24fps (actually movies mostly are 23.976) with 60hz you get whats called judder as it has to do a pulldown and skip a frame every 48 seconds (I'm not sure it is 48) and then you get judder. Most people don't notice it but I have an eye for details and always see when video doesn't play smooth.

Hz are not FPS. not by a long shot.
Just don't get those two mixed up.
I'm not going to argue with your statements... but your must be running crappy software if you have issues like this.

I am right, there's really nothing to argue about here, read this if you want to understand how it works http://en.wikipedia.org/wiki/24p
i know what I'm talking about. Sure some tv's have a good pulldown system, but you always want to prefer 24hz when watching movies (or as said before anything dividable with 24)
i don't have any issues at all, I think you completely misunderstand everything. I run xbmc and vlc for video playback, it works awesome on my pc connected to my projector with [email protected]
and WHY I want to know if the tegra 3 can do this is because I might want to book an Ouya and it's the last week for pre-orders and I can't find any info anywhere about wether it will support 24p. XBMC will soon be released for android and if I can't use the Ouya as both a gaming console and a media player I can't motivate getting one.

why do you keep saying 24 hz?
its 60 hz, 120 hz and 240hz these are the hz frequency that modern displays use interchangeably and out of those 3, they all display 24 FPS natively unless the file source that's being broadcast (or played from disc) is streamed in a higher FPS such as 30 or 60. most shows and DVDs are in 24 FPS simply because it provides a more cinematic experience but that's it.
there is no 24 hz... you are using some terms incorrectly from reading too much online and not understanding everything.
that link you referenced us using the term 24p in reference to 24 FPS which has to do with how many frames per second display on your tv which is NOT the same as HZ.
really stinks seeing people argue like they know what they are talking about when they don't because they read on wikipedia and misinterpreted the information.

Unless you live somewhere not in North America, or anywhere that uses NTSC guidelines, no electronic equipment runs at 24Hz.
The stutter you claim to be able to notice just happens, and that's about all there is to it.
For someone that claims to know what they're talking about, your lack of knowledge of very basic power terms is saddening.
However... one thing that may work is 240Hz. It is both a multiple of 24 and 60, therefore A couple TVs can run at it, I don't know if the tegra3 can output it.
However, since very few TVs can run at 240Hz, I'm doubting yours can, and then since your TV can't decode 240Hz, there is no point in this discussion.

120 is also a multiple of 24 . Just about all so-called 100Hz TVs sold in Europe are also 120Hz sets and will therefore handle material fed at 24fps with no issues - at least none that are related to frame rate/refresh rate issues.

Lol and to think, I'm in second year engineering. Guess that's what happens when you don't have a calculator. Lol.
The idea though is that at 60Hz, TVs display frames for 2-3-2-3....4 cycles, and this is what he's referring to. He wants to get rid of the extra frames and such.
Since its all dependent on the power fed into the TV, at 100Hz there is no way to eliminate the 3:2 cadence.

Fundamentally, you can get one frame per cycle. However, if the frame rate is low, the display will show the same frame for multiple cycles.

Edit - sorry. Displays show one frame per cycle. If the frame rate of the driving thing, movie or game or whatever is lower, the display will show the same frame for multiple cycles.
Edit 2 - the op mentions his PC driving his projector at 24Hz, but does not mention if its over HDMI, VGA or any derivative there of (DVI)
Afaik, HDMI does not allow one to modify the frequency.

Thread ressurection "rise from the dead".
of course 24hz IS 24fps ON the screen you are viewing. but that doesnt mean that the video was filmed in 24fps (almost all movies are though...although Hobitt is 48fps).
To be clear. If I take my Blu-ray and play it through my PC output at 24hz to my Vizio TV which can indeed display 24Hz, then bingo! I get a 24fps movie playing at a matched 24hz TV image (which flashes 24 times second). This synchonisity creates a very "movie like" experience.
Now, can a Nexus output at 24hz and do you have a cut that runs from a player at 24fps? I'm not sure. But Blu-rays will tell you is they work at 24hz (like Blad Runner does) and if you blu ray player outputs 24hz and your tv accepts 24hz, then your 24fps movie will look like it does in the theatre.
My samsung galaxt note 2 has a power saving move which cuts down the screen hz from 60 to 30 (or something like that) to save battery...so I know hz adjust,ent is possible ON the phones screen...but I imagine that its the video player itself and the hdmi out that handles sending a signal out at a specific hz.
I'm gonna dig arouund and look for a hack.

[Q] Highter resolution Webtop ???

hi when i enter in "weptop" mode i cant set highter resolution, actually its 720 and my TV supports 1080p.
the other issue i have its my tv supports @120hz and the problem its some colors sometimes looks weird :S i cant set up to @120 hz the max its @60hz 720p
anyway to change this??? my tv its vizio
Thanks a lot.
1080p is quite a lot for a phone like this, so performance would be bad.
I haven't seen an answer to your question on this forum, however. sorry, cant type fast cause on injury otherwise i'd give a more detailed response

Ok so as far as the 1080p thats too much for our phone to handle and it will not make it any more sharper... and for part 120hz, that's only the output not the input... Every thing out there form dvd's to vhs and xbox's and blu rays spits out a 60Hz signal and what your tv does is it doubles that 60hz and makes it a 120Hz signal which is what you then see... but most likely you dont even have it turned on... Check your settings that would be your best bet...

I doubt the atrix could render and pipe it over hdmi at that speed. Can't you just use the laptop? I don't notice much between 720 and 1080 videos except for horrendous load times.

Hi there!
So thats kind of a problem. If you plug in your Atrix to an DVI computer-screen, as mine has got 24" 1920x1200 pixel, you cant really get that native resolution?
About performance: as long as you dont watch 1080p youtube-files, it would be alright, I guess...
As the hardware (though the tegra 250 developer board does) is able to output 1080p, is a solution possible?

(edit: I even consider using a kindof HDfury hdmi to vga converter for a beamer in full resolution...)

120 vs 60 hz would make no difference on color

if you have the modded webtop, with sudo permissions and lxterminal or something similar, just write xrandr -s 1920x1080 in the terminal and you should get a 1080p res.
the frequency (120 hz vs 60 hz) has NO effect on the colors of your output. it's either an issue with the connector (HDMI cable) you're using, or the TV itself. my guess is something on your TV settings is off, if you're getting the same problem with both the Atrix and a separate laptop.
by the way, a 120Hz capable TV still runs 60Hz images at 60 Hz. There is no "doubling" going on, it's just capable of displaying images with refresh rates up to 120 Hz (higher is more refreshes per second).
i think, that Nvidia Tegra 2 Cant render out 1080p resolution, because this "advantage" will be in Tegra3 (as the part of its specifications).

Changing Display Refresh Rate?

Is it possible to change the Refresh Rate of the screen? The reason being that when I play 25fps movies or 24fps I want them to play judder free, just like my TV which changes to 24p.
The refresh rate and the frame rate are not related:
http://en.wikipedia.org/wiki/Refresh_rate#Liquid_crystal_displays
http://en.wikipedia.org/wiki/Frame_rate
If you are seeing judder, the cause is not the refresh rate (which is 60 Hz). A typical DVI / HDMI desktop LCD screen also has 60 Hz. Have you seen judder when watching a movie on the desktop display?
Yes on a 60hz display you get judder on a 24p source, which is why tvs render at a multiple of 24.

I'm looking at the first episode from Game of Thrones, 720p, 23.976 fps. I see no difference between watching it on SGS2 and on a display with HDMI at 60 HZ (other than being ultracrisp on SGS2). I also see no "judder difference" between this and seeing a movie at the cinema. Could it be that I got so used to it? Could it be that the software players do such a good job? I can see some judder occasionally, if I sit really close to the display.
The comments from here are very interesting.
It's because you are used to it. Please do not read anymore of my post if you are used to it because once you see it, you will see it everywhere!
Basically when you play a 23.976fps film on a 60hz display it doesn't divide into a whole number, so some of the frames are repeated which causes less smooth motion. You notice it mostly on panning shots. A good example of it is in opening sequence of the film Shooter (2007).
You'll always have judder from the nature of 24fps video, as it's low frame rate in comparison to what the human eye can perceive which is probably around 50fps. To notice it, take a look at any talk show or sports broadcast on TV they are broadcast at 50 and 60fps. If you slowed that down to 24fps you'd notice straight away.
Btw started watching games of thrones last night, great show!

Best Buy is selling a 720P Dynex TV for 249.99. I have had my fair share of HD TVs and I must say anything over 32'', 1080P is preferred. 32'' and below, you won't notice the difference between 720P and 1080P. Again, my own opinion.

it depends on a few variables. How far away will you be sitting? How big is the screen?
I have a 62" 1080p in my bedroom. It is a large bedroom and my bed is about 14 foot from the screen. I like the extra resolution at that distance.
I have a 50" 720p in my living room. my couch is only 10 foot from the screen. It is fine at that distance. If I push my Couch back to where it would be closer 12 foot away though, not as good.
I say a 720 is fine on 50 our less as long as you aren't sitting too far away.
But it also depends on how much difference in cost you are talking. A few years ago there was several hundred difference between the two. Now I think the gap has closed.
I would opt for the 1080, but the 720 wouldn't be out of the question.

yea i got a 720 p 32 inch and it looks just ass sharp as the 50 inch 1080 p in the other room i say if its a small tv 720 p is fine but if its over 32 i would get 1080p
I bought a 42 inch insignia brand 720p plasama for 185 on black Friday
I only use it for my xbox 360 ... It really all depends on what it will be used for... And most things upscale to HD.but that is a whole other topic/debate
Personally i dont see a difference in a tv thats 32" or smaller.
Everyone has hit it right on. 32 inches and less no user discernable difference between 720p and 1080p. Larger than 32 inches I would not get a 720p, however there are not many available anymore.
Also to consider is the source.
Blue Ray is 1080p
HDTV depends on the service (satellite, cable, etc.) but most TV is either 1080i or 720p and from what I've been told the way 1080i scales on a 1080p tv it is no better than 720p.
Also, different carriers compress their signal more or less. My experience has been that Time Warner really compresses theirs and so HD on Time Warner Cable looks like crap. I have Dish Network and it is great. Some Prefer Direct TV, but I have always thought my Dish Network service is the sharpest.

Get the 1080p tv and stop looking at those 720p ones less your looking for a tiny thing.
end of story.
Just as everyone has said, it really depends on what you are connecting to it. I know what you are talking about, and right now, you can get a steal of a deal for a 50" plasma 720p for like 6ooish. Who is your cable provider? Do you have HD setup? Do you have a blu-ray player? Are you connecting a ps3/xbox to it? Personally, I would rather have 1080. It's not that much more price wise. You can get a 51" samsung 1080p for 899.

Even the 3d TV's are dropping in price too. Look around at Brandsmart, Hhgregg, tigerdirect.com, newegg.com, and microcenter.com. Some of the best prices I've found. I'm in the market for a 50" 3d tv, but haven't found the one just yet.
1080p or higher.... Nothing less.
If you have the money go for 4k x 2k
I use my 32" as a computer monitor so 1080p is Needed otherwise everything would be huge..its got 3D too so I'm all set. $500
Nothing fancy,just a Vizio.

Unless you are using a CRT 1080i is not as sharpas 720p FYi. 1080i is interpolated from 2 560p images. CRTs are designed for interpolation and LCD's/Plasmas are designed for progressive "i" vs "p". So on an LCD/Plasma you are going to lose quality. So in the case of HD screens bigger #'s don't always mean better. Also refresh rates and contrast ratio are other factors you need to look into. The bigger the Hz the better, the smaller the Ms the better and the bigger the contrast ratio the better.
If you never saw a movie 1080p and ony ever saw moveis in 720p you wouldn't know you were missing anything. If you aren't bothered by the fact that you will know there is better out there and the movie you are watching can look better, then 720p will be the better choice. If that will eat away at you whenever you watch a movie then get a 1080p because you will end up with one anyway.

Can this phone play 720p?

Just wondering...else I have to convert to 480p
Yes it supports 720p (and 1080p) movies.
you guys have to always remember that what it supports and what it can do flawlessly are two separate things....
720p videos films are playable but not the smoothest.
actually,For me,720p and 1080p vids played quite smoothly (maybe a tad slower than my iphone4 but nothing notable really)
Interesting, I didn't even try 720p. Good to know it works, but really it generally would be worth your time to convert. Huge waste of space if you don't plan on deleting it right after viewing.

Yup I had to convert a 2.5 gb vid from avi to mp4 and it was about 3.7gb

I assume you used Zune to convert it, if the end file ended up being bigger than the original.
A properly transcoded video would be significantly smaller: a 720p video has 921600 pixels per frame, as opposed to the resolution of our Titans; 480x800. A wvga video only needs 384000 pixels per frame. Therefore a 720p video is roughly 2.4x larger than it needs to be as our screens cannot display pixels it doesn't have (and that's not even taking bit rate into account). The quality will actually be slightly worse on a 720p video because it will have to be scaled down to play on the screen, whereas a properly transcoded video would be 1:1 with the pixels on the screen.
I mentioned bit rate; I don't really know what a good marker for bit rate is, but when transcoding to a smaller resolution, you don't want to keep the original bit rate: that has to go down too. Bit rate plays into file size significantly, so in reality any 720p video is much more than 2.4x bigger than it needs to be.
I guess one of these days I'll play around with a transcoder and make a thread about how to properly convert a video for WP7.

1440p virtual reality demos

So I just bought a Homido to use with the nexus 6p. It's fun but the resulting image isnt too sharp. I think this is because demo movies are 1080p generally and since our phone is quite big, the resulting image isnt too sharp. I wonder if someone knows a source for 1440p or 4k SBS movies to demo ? I couldnt find any myself. Not youtube but real movies for download, shot in QHD or UHD. Please share if you've found something in this thread, thanks !
Actually I'm starting to think there's currently just *no* SBS content higher than 1080p, even on the torrents I can't find anything higher than 1080p, that's quite a bummer ... Still, if someone knows a demo or something >1080p, please do share !
Actually so it seems the SBS format only goes up to 1080p24 ... Just starting to look into this, but wondering now if there's a format that supports higher resolutions ?
*EDIT* also just found this article, the makers of the Oculus rift say that 8k resolution per eye is needed to truely get rid of pixelation: http://arstechnica.com/gaming/2013/...esolution-per-eye-isnt-enough-for-perfect-vr/ and the article makes a point that you need even a multiple of that to get rid of aliasing.
Oh and 500 fps, hehe.
That seems still quite a few years away, lol.
Currently virtual reality is interesting but I understand now we're still quite a few (probably 10) years away from hardware that can generate a really good VR experience. 1080p24 just isn't it....
To answer my own question:
Full SBS = 3840 x 1080 which exists but requires specialist playback equipment
Half SBS = 1920 x 1080 which is very widespread and also of course broadcast-able.
So Full SBS is actually 1080p *per eye*, so our display cant yield true full SBS unfortunately.
