A friend just brought round his Xoom so we could run some tests on it for a video project involving HDMI. However, our HDMI conversion unit didn't recognise the tablet's output, even though 720p/50 is one of the formats it accepts.
So we plugged it into our TV to check that the HDMI out was working, and it flashed up 720i. Our conversion unit doesn't recognise 720i, so that's consistent across both devices.
So are the specs (which say 720p) wrong? Or am I missing something?. Do other users get 720i when they plug the HDMI into the TVs?
https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/61611/~/xoom---hdmi
The xoom produces a mirrored output I think, it takes 1280x800, chops off the bottom 80 pixels and produces a 1280x720p output.
There is very little chance this device would send out an interlaced image.

So why is my TV showing the input as 720i?
My question is to people who actually have the Xoom. Are your TVs showing 720p or 720i when you plug in your HDMI?
C'mom there must be someone here with a Motorola Xoom besides me.
Proof that it's 720p.
Thanks - that's very kind of you. Now I have to figure out why it's showing up as interlaced on my TV, or if it's just a weirdly misleading artifact of dodgy hdmi handshaking. My converter can allegedy handle 720p/60, so it's all very strange.

I bought an HDMI cable today so I can put Netflix onto my TV. I have an older HDTV, from 2004. It's a Panasonic model number pt-47x54j. When I plug my tablet into it, the little Android dude pops up onto the TV and and says 720p? I checked the owners manual and it says that the TV is only capable of 1080i, or 480p and 480i. I plugged my tablet into a more modern HDTV and it works just fine. Crystal Clear. Is there any way that I can get my a500 to work on my Panasonic TV? Attached is a screenshot of my TV's owner's manual on the page where it talks about HDMI inputs. Thanks in advance...
From the best of my knowledge you can't change this.Athens beat solution I could offer is Logitech Google TV.it rocks.and 70.00 amazon.
It can't be changed without hacking the drivers -- and even then micro HDMI is only capable of 720p output. All you can do is use a different TV or an adaptor (probably cheapest, but may lower video quality).

Thanks. At this point, I'm just using my tablet to watch the movies on. That's good enough for me. Once my TVs start breaking and/or if I get this dream job that I'm currently chasing after, I'm going to get a more modern TV and all of my HDMI cable worries will go away. I put the Netflix App on my phone too. My 3 year old freaking loves it!! He is always asking for my phone to watch cartoons on. It's hilarious. haha
Of course, I'm still going to try to figure this crap out with my current TV. That's the fun part.

micro HDMI itself is capable of 1080p, but the tablet will only output 1080p if there's a 1080p stream (such as a 1080p movie). Netflix will not do 1080p, though.
I demonstrate the HDMI output capabilities of the Amazon Kindle Fire HD 7" Tablet. I am very impressed with this feature.
PLEASE NOTE: This video does not do the output justice. Trust me, the color is very accurate and the contrast and saturation are very close to what you see on the tablet's screen. Unfortunately, this video shows the TV as being a little blown out. This is not the case in real life.
Stay tuned for even more videos soon!
I'm getting more and more convinced to buy one, keep the vids coming :]
If the video on the KFHD is only 720p is it outputting 720p or 1080p to the TV?
Do you know if Amazon instant video support 1080p output via KFHD?
Thank you. I'm wondering abouf upgrade from KF to KFHD and 720p v 1080p output would make the difference.
Hello?
If the KFHD renders at 720p how does it output at 1080p?
Does the processor process at 1080p and downsize to the 720p KFHD or are there two seperate renderings one for tablet and one for HDMI?

I'm not sure how to determine what the output is. It looks fantastic to me, but I can't give you specifics on whether it is 720p or 1080p. I'll do some further research.
>If the KFHD renders at 720p how does it output at 1080p?
HDMI output is [email protected] That's what the TV said about the input feed in OP's video.
UI display is undoubtedly upscaled from KFHD's 1280x800 (some top/bottom slice is likely cut off). Video render is likely native 1080p. It's easy to tell: Freeze-frame at a detailed frame and peruse the detail. Compare it to native 1080p playback on your PC. You should be able to see the diff if it's scaled-up 720p--and if you can't, then it's a moot point anyway.
Edit: On second thought, if the video is shown on both KF and TV displays, then it's probably scaled up 720p. To do native 1080p on TV, the KF would need to render two different res simultaneously, which may still be within the 4460's capability, but isn't the most expedient route.
Edit2: From looking at OP's vid again, it looks like KF preserves the entire UI display on HDMI out. So instead of lopping off the extra 80pix and losing part of the status/menu bars, it squishes the 16:10 AR down to TV's 16:9, which is preferable, as you can't normally tell the difference anyway.

Sounds about right. There is a TINY delay in the TV, so it's possible that is stemming from an independent render from the actual tablet's display. Either way, it sure looked good.
That is what I stated e.mote.
A video was played that was supposedly 1080p. Now the KFHD has to downscale the video to 720p since the resolution of 720p is 1280x720. The KFHD is 1280x800 so it will fit the screen with 80 extra vertical pixels.
1. Either the KFHD is sending the 1080p video output to HDMI before it downscales the resolution
2. The KFHD sends the downscaled resolution to HDMI
3. It has a seperate rendering for both outputs.
reverendkjr: If you could take two pictures of the KDHF playing a video in both 720p and 1080p and compare them we could more easily arrive at a solution.
Thank you.

I don't think that a picture is going to help here. I watched a 720p and a 1080p trailer on the device. They look identical. I could not see any difference at all. I also looked at the TV playing both. There was a definite difference. The 1080p was indeed a lot higher quality.
My conclusion:
On the device, it scales. So it can only play whatever resolution the device can handle. In this case, 1280x800.
The HDMI must have it's own render, because I believe it was definitely playing 1080p on the TV.
>If you could take two pictures of the KDHF playing a video in both 720p and 1080p
You can't take a snapshot of HDMI out. The reason content vendors selected HDMI is that it's a secure path which prevent signals from being captured (read: pirated). There are HDMI recorders, but AFAIK they do analog captures, which means a fidelity loss.
The only sure way to tell is from the eyeball test, which needs to be done firsthand. If you're that worried about it, go to a BestBuy and ask to have the demo model plugged into a TV display, then run a 1080p clip and do the eyeball test yourself.
I apologize if my request was not sufficiently clear. What I meant was a picture of the TV via HDMI out of the KFHD with a lens that captures images with a sufficiently high resolution.
For now, as it is apparent you have, by your testimony, tested via direct visual experience, I will grant that you are correct and that the output of 1080p video is of significantly higher quality compared to that of 720p.
Thank you reverendkjr.
Well I have a cheap router and only a small cable modem from Verizon and I can get Netflix to play what I'd call more than acceptable on the KFHD. However, going to the TV from there, the picture is not even close.
If it was bad on the KFHD I can understand. Does something have to be enabled or maybe it is the cheap cable I picked up from Best Buy that I use with my Acer A500? It works at least so I thought it would be compatible with the KFHD but maybe not good enough.

You have to check your bandwidth. Since you're on your KFHD it might be difficult.
Netflix 720p requires about 5mbps. You can Google bandwidth test from a PC to check your download speed. If it's less than 5mbps your video won't be 720p.
http://en.wikipedia.org/wiki/High-definition_video#World_Wide_Web_HD_resolutions
It looks like Amazon instant is only 720p. Netflix only supports 1080p on certain devices. So much for 1080p.
Cable modem and router to my KFHD I understand about bandwidth and the PQ is very good, BUT I I'm unaware of bandwidth being an issue from KFHD to TV unless I'm mistaken.
I need to read other experiences with this feature and how good or not it is. Something tells me it isn't the cable I'm using either from KFHD to TV.

:crying:
Well KFHD has less than half the pixels of a 1080p TV and the pixels are much more dense in terms of ppi(pixels per inch). When you view the video on your KFHD through netflix and the stream is less than 720p due to bandwidth constrictions, it is entirely likely that the picture will look fine on your KFHD but inadequate on a larger TV with a much lower pixel density.
If your bandwith is less than 5mbps you won't be viewing HD video through Netflix, it will be SD (standard definition) which won't look good on a HDTV.

Thanks for the clarification.
I have a Blu Ray player I stream movies from to the TV which is pretty good so not having a great picture from the KFHD to TV isn't the end of the world to me. I don't stream that much really, I just flip in a Blu Ray disc for PQ nirvana.
I picked up a cheap HDMI to HDMI micro cable at Best Buy to test the HDMI out on the Kindle Fire HD (Rockfish)
I tested the HDMI output playing a couple of HD movies from Amazon Prime (True Grit and Into the Wild). Both of these movies look fantastic on the Kindle Fire HD. However, when viewing on the my HDTV's, the quality of the video is not that good. For example: It's not nearly as sharp as an HD program via Direct TV for example. The picture is kind of washed out and not very clear. It looks a lot like SD instead of HD.
I also noticed that the audio is not being output as Dolby Digital 5.1. I was hoping that it was.Has anyone had any luck Dolby 5.1 sound output?
Note: I tried it on 2 TV's (One 50 inch Samsung 1080P Plasma and also on a 37 inch Panasonic 720P Plasma). Similar results on both. Maybe it's the cheap "Rockfish" cable I picked up at Best Buy to test with? Maybe I'm missing a setting somewhere? I was hoping for typical HD quality picture when using the HDMI out. But, I'm not seeing it on my TV's at least. btw....I have charter cable internet (50mbs download speed)....so plenty of speed.
I tried outputting to a smaller Sony HDTV display, 32" instead of my Samsung 40". While better, movies isn't something with my current router and cable modem I will be doing from the KFHD.
I have an Acer A500 which has HDMI interface as well. Maybe I'll try it again as I cannot recall if the pq was any better.
As far as the HDMI cable? I'm still unsure if a higher quality one would make any difference whatsoever given my router and cable modem bandwidth to begin with.
There's always games though. Riptide is lots of fun so a plus for that to my HDTV displays!

Thanks for the feedback on the HDTV test. I was really hoping for some better performance for Amazon Instant "HD" video when using HDMI to output to my 50 inch 1080P Plasma. However, based on my testing, the HDMI out on the Kindle Fire HD is something I would never use. At least not for watching Amazon instant "HD" video. I was hoping for something along the lines of what I see when I steam a movie using the Apple TV (really good "HD" picture quality). Still the Amazon instant "HD" video looks great on the Kindle Fire itself & at $199 it's quite the deal. Just wish I had an option to see "quality" Amazon content on my HDTV's (ie without purchasing another device like Roku).

I tried hooking up my Nexus 10 to my TV today via HDMI and found that the video out doesn't work properly. My TV gets a black screen but audio works fine. I know the device's HDMI out works fine because I can hook it up to my computer monitor and it works fine. I'm not trying to play any copy protected content, I'm just trying to get my display mirrored. As an additional note, I've gotten my Galaxy SIII to hook up to the TV fine.
Any idea what may be wrong?
Just came across this myself.....
Maybe it tries to display a resolution it doesnt support?
Does your computer monitor have 2560x1600 resolution support?

No, my monitor is a 1920x1080 resolution, and my TV can go up to 1080p as well. I tried on the TV to set the scale to "unscaled", "automatic", and "widescreen"
The Nexus 10 converts the hdmi output to 1080p automatically to be compatible with your HDMI tv. I just read that one, not sure if it is compatible with lower resolution televisions.
SeattleAndrew, by chance are you attaching to a Panasonic HDTV? I ask as there is another thread in the Nexus 10 forum on this same subject. In that thread a number of Panasonic owners had varying results.
I also have seen differences with HDMI connection between manufacturers. Samsung seemed to accept a wider array of HDMI/Device connections than Panasonic.
Just my 2 cents.

Well, been looking everywhere can't find any output specs on it specifically. Just general reference to standard converted output to 1080p. Learned way more than I ever wanted to about hdmi. Maybe most people think the hdmi output is 1080 because they are using a standard cable rated for 720p/1080i when a high speed hdmi cable is required for 1080p, 4k, 3d and high color. I guess you guys that have done it would know more. So someone not getting the connection/performance with higher resolutions might need a hs data micro-hdmi cable? (source = Wikipedia, subject = Micro-hdmi)
Hey, wondering if anyone else is getting varied resolutions when using a micro HDMI -> HDMI cable into a TV. We have a 37" plasma 1080 capable but I only get 480 out of, and our 42" LCD only gets 720.
Both are default numbers as I haven't been able to find anyway to adjust them. Have tried stock video player, MX player and YouTube through all to no avail.
If anyone has any ideas, I'd be most appreciative.
Cheers

You may want to check your hdmi cable. If you have a "standard hdmi cable" , and it supports up to 1080i/720p. The type 2 "high speed data hdmi cable" supports 1080p, 3d and high color. Your tv's and tablet may support it, but you may be using a standard hdmi cable.

Listed under specifications/cables
I haven't looked, does the n10 support 1080i?... I notice most devices and movies I look at only support "p" areas (480p, 720p and 1080p) relevant since I plan to buy a big screen LED tv with my tax return...
Cheers for the heads up, I've read in other forums that the n10 downscales to 1080, but haven't seen it first hand.
There's a few variables at play, I'll get some specs from the TV's, I haven't seen any different type of cables on eBay else I'd have got the better one (i spent $15 on this one).

I purchased a $10 off of Amazon. Supposedly a HS cable. Real thick and almost 6 feet long.. Nice, but the TV I had planned to use it on, it did not output sound! 2 other sets, and the sou d works fine. I read here that it is a cable/tv combination problem.. Plug in another hdmi and the sound will work fine. Haven't tried it since I hooked it into the stereo via blue tooth.
I am planning to buy a small converter attachment,(pigtail cable or plug) that way I can use the hs hdmi cables I already have on the tv. I am still not convinced that it isn't a problem with android, but we'll see.
Hi, all just thought I'd share a tip about how to upscale your movies to improve picture quality.
Purchase Seiki U-Vision upscaling HDMI cable
https://www.youtube.com/watch?v=NQkDG7ofjDo
http://www.amazon.co.uk/Seiki-SU4KC1-SEIKI-U-Vision-Cable/dp/B00IE5C6LO
Side Load your favourite video streaming app onto your FireTV.
Set your FireTV display output to be 720p
Stream movie.
The premise of this assumes that your movie stream is not being shown in 1080p, so instead of just stretching it, you instead direct the video output through the cables onboard upsclaer which fills in missing detail and outputs it again in 1080p.

Hi,
Will this work with any streaming app like Netflix or Amazon Prime Instant Video?
Thanks!
This sounds promising. But would you really have to set your max output to 720p? Couldn't you just leave it set to a max of 1080p? I would think the 720p stuff would look improved, but the 1080p wouldn't look any different.
Anybody else try one of these gizmos? I'd love to hear more feedback on 'em.
Normally those cheap upscalers do not improve the picture quality in fact it´s even getting worse due to the simple resizing than using the original output size and let the TV do the upscaling with their more advanced chipset upscalers. There might be also some HDCP problems since those cables are working as additional component in the HDCP handshake chain. I suggest to look for some user critics for e.g. on amazon. I personally wouldn´t buy one.
I actually have one of these cables, which does have its own dedicated upscaling hardware you can google lots of positive reviews about them...
As for improving quality the point of downsizing the resolution to 720p of the firetv is that it then matches the resolution of lower quality streams. This then will run all video being output through the upscaler no matter what you are playing.
Ofc there's no point trying to upscale a 1080p stream back to 1080p.
Running the Fire TV through at 1080p would upscale it to 4K
From my own testing the cable did convert the video back to 1080p with picture quality improvements (note I was not watching a 1080p video in the first Instance)
I think it's intriguing enough to give it a whirl, especially if you get it off Amazon and can return it easily enough if the performance is sub-par. But looks like Amazon's sold out of 'em this week (though you can buy it for a bit more $ from a third-party vendor).

Yeah I mean the general premise is that you take your crappy looking 720p online movie stream and then force it through the upscaler to improve the quality along the way to it being converted to 1080p...
The reason why you set the the FireTV also to 720p as it will then trigger the upscaling upto 1080p... otherwise all you're normally doing is watching a 720p movie but just stretched to a 1080p resolution which looks even worse
EDIT:
I'm yet to find a side by side comparison online to see if it really does improve the quality as all of the reviews are focused on the upscaling to 4K which do seem to look razer sharp...
I would have done one myself but I don't currently have a camera tripod to make sure im taking a picture from the exact same perspective each time... You would also need a hdmi switcher so you can easily change between hdmi cables.... but tbh its not alot of money and worth a punt
Just from a purely subjective standpoint, do you feel like you're seeing a definite improvement in picture quality?
We watched Rio 2 last night in 720p and it looked like dog doo.
Hey, death_entry, could you tell me how long the USB cable is? I'm assuming it attaches to the main HDMI cable at some point, and I need to know just how long it is. I don't have a USB port on my television, so I'd have to power the cable from somewhere else -- either the FireTV's USB port, my new TiVo OTA unit (which has two USB ports), or perhaps something like an iPhone USB charger, where I plug it into the wall and maybe run a USB extension cord to the U-Vision cable. Hopefully one of the above would provide adequate power for the U-Vision to do its thing.
