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?

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.
Has anyone gotten the tablet to output using a Dvi to HDMI converter? Is there a way to controllvthe output settings on this device because it seems as if its outputting HD at a different resolution then what's my monitor supports. I get a signal with no video.

The Iconia Tab A500 currently supports output resolutions of up to 720P through the HDMI port. Support for 1080P resolution videos will be added in a future software update.
try setting your tv/monitor-graphics card to 720p for now, official 3.1 release should enable 1080p....hopefully. 720p still looks quite good on my sony.
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.
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.
I just connected my SM-N9005 via HDMI to my monitor (Dell ST2420L) and everything is fine, except the resolution. It looks a bit blurry to me.
When I checked in the monitor, it says:
Current: 1280x720 @ 60 Hz
Maximum: 1920x1080 @ 60 Hz
The native resolution is shown 1080 x 1920. But this is not the case with HDMI.
I've tried 3 different apps to change the HDMI resolution (with Root) without success.
Does anybody know how to change the resolution?

What kind of connection do you use? If it's MHL, then it must be due to the version of MHL adapter. AFAIK MHL below 2.0 does not support Full HD, that is 1920x1080 @ 60 Hz.

That thing doesn't look particularly trustworthy. Was there any reports about this cable being capable of Full HD output?

All HDMI cables are essentially the same. http://news.cnet.com/8301-17938_105-20056502-1/why-all-hdmi-cables-are-the-same/
The problem is related to the phone.
http://forum.xda-developers.com/showthread.php?t=2120779 Looking at this thread, I was able to locate where are the config system files.
In my case not all modes are listed and 1 file is missing (since this is newer phone than S3)
I hope someone can help here with the settings.
Edit: Just found another frustrated Note 3 user with the same problem: http://forum.xda-developers.com/showthread.php?p=48160265
after some cables getting 1080
I had one MHL and got a 720p output. Switched to another one (mhl2) and am now getting 1080p, according to the monitor. However, many apps still don't take advantage of the real estate. They still pick a display format that assumes the device is a phone and so for example, only show 3 or 4 items in the email list.
Android UI stuff isn't ready yet for the kind of adapting/switching we're used to on Windows/Mac/X.
So you are saying that it's probably because of the MHL cable?
MHL cables are same. MHL hardware is different. The MHL plug has 11 pins.
What brand did you get that works?

I believe there're some apps and/or ROMs that let your phone run apps in tablet mode, for example: http://highonandroid.com/android-ap...-mode-on-any-rooted-android-smartphonetablet/
Though this will be of little help if the app does not have a "tablet mode".
Install xposed installer, there's a tweak that allows you to use the resolution you want to on your TV. I dunno what is called but I'm sure it is in xposed installer!
This will help your problem 90%

Thanks! I forgot to check Xposed! Will report in a minute
Edit: Unfortunately I wasn't able to find any mod for HDMI except Fullscreen YouTube
Edit 2: Just used Galaxy S3 with the cable and works just fine on 1080i. So it's definitely not the cable. Sounds like firmware bug (MK2)
Have you tried changing the pixel density (PPI)? PimpMyROM and Xposed can both accomplish this task. Since screen mirroring simply takes whatever is on your device's screen and relays it onto the HDMI output, you can start by taking better advantage of your internal 1080p screen! I recommend 360ppi for this device, as that is the setting I am currently using. You can also go as small as 320ppi without losing sharpness, although text will be extremely small at this setting.
Im not inrerested in changing DPI, just the HDMI resolution
MHL 1 supports up to 720p (1280x720 @ 60Hz) or 1080i (1920x1080 @ 30Hz), MHL 2 also supports 1080p (1920x1080 @ 60Hz).
There is no way to change the resolution, the phone will output the highest mode it detects as being supported.
There are a huge number of fake MHL2 adapters on the market, if you think you got an OEM one for a good price, then it's probably a fake one.
Remember that the native resolution of the Note 3 is 1920x1080, so you can expect a 1080p TV to display the same as the phone does, it doesn't have a special "HDMI mode".
As computer monitors generally don't support 1080i, then the output will fallback to 720p mode and as LCD screens generally don't scale very well, the resulting picture will look fuzzy.
Your only real option is to probably going to be to buy a proper MHL2 adapter. The monitor will probably also not support MHL directly so you'll still need the external USB power supply, while most TVs will accept the HDMI input, they don't support MHL so won't supply power to the adapter over HDMI. It seems to be mostly higher-end models that support power-over-HDMI.

It's not the cable as it's working fine with S3 @ 1080i. And it's special 11 pin for new Samsung models so it's MHL2 compatible and doesn't work with other devices. It's not the monitor. Other people report same problem and nobody knows a fix yet. I'm sure it's the firmware.
In the system files it shows available modes:
1280x720-0 and 1920x1080-2 (I don't know why -2, but nothing can change it, I tried)

Having an 11 pin connector doesn't guarantee that it's an MHL2 device. I have 2 such units sitting in a drawer beside me which have a MHL 1 SIL9292 processor chip in them instead of the SIL9296 required for MHL2 & 1080p support. It works fine with my Note 3 but they do not support 1080p output.
MHL cables are not straight-through MicroUSB to HDMI adapters, they all have active processing circuitry in them. It's not like a regular HDMI cable, that's why the plug on that cable you bought is so huge, if you crack it open there will be a circuit board in there with a MHL to HDMI processing chip on it.
I know 2 other people with Note 3's who have genuine Samsung MHL 2 cables and they both get 1080p output on their TV's.
Computer monitors except for some rare exceptions will NOT support a 1080i input as they don't have deinterlacing circuitry so a lower support resolution will be negotiated. Having the issue on a TV that definitely supports 1080i is a different matter.
The Galaxy S3 is natively a 720p display so scaling will not be required meaning that you will get a much better picture from a Galaxy S3 @ 720p than a Note 3 @ 720p as it can display the image 1:1 without resampling.
ALSO - The Galaxy S3 itself doesn't support MHL2 so is not a good reference.
Read all about it: http://www.galaxymhl.com/
Thanks for the useful info. That explains a lot and I will buy genuine from Samsung. Cheers

You might have to go find an MHL1 adapter instead of an MHL2 adapter.
