HDMI

Can you output 1080p (or even 720p) video out through the HDMI port to a nice big TV?
I was reading somewhere that this may not be possible...

I was told you could and I can't imagine why you wouldn't be able to but I haven't tried it yet. Need to find a cable

Thanks for the reply. Anyone actually have a cable and been able to do this?

I think it's micro hdmi so I have a cable but no xoom yet. One of the first things I plan on testing when it shows up next week.

Some reviews I read said u actually need the HD dock to use hdmi out I don't even have the cable so I myself am wondering the samething

http://forum.xda-developers.com/showthread.php?t=967922
No need for the dock. The thread of someone having used it was pushed down to page 4.

That show's mirroring though. I want to see true Video output in 1080p.

I used my dx hdmi cable too hook up to me 65 in dlp and got 720p.
It basically just mirrors screen. I couldn't get xoom screen to turn off though. Didn't wait that long.
Watched some of a AVI movie via rock player and worked very well. Not 1080 though

Xoom Hdmi to dvi output not working. Blank screen.

I have a micro hdmi to full hdmi that i use for my xoom and evo to connect ot my 65inch tv. It works great and I love it but in my bed room i have a 30 inch tv and it only has dvi input. So i bought a hdmi to dvi adaptor and was so happy to get it and my luck it doesnt work. The tv doesnt detect the input and says its not active. I got the tv to display the xoom a few times but the tv pops up a box saying Signal test...which is what it does when there is no signal/input. I tried to plug it into my monitor with the dvi adaptor and the screen is blank. Really makes me sad i was so exited. I pluged my evo into the cable with the dvi adaptor and it does work so im not sure why the Xoom is having issues. I also plugged in my laptop into the tv with a full hdmi cable and used the dvi adaptor and it worked perfectly. Not sure if anyone else has the same issues. Any help would be appreciated.
Thanks

Does that TV display 1080p? The Xoom will mirror itself in 1080P - If that TV cant handle it, it wont display it. Most old school 30 inchers are 720p max

To be honest, if its working fine with the cable on another TV;
then its either the adapter or the TV input - but the most logical explanation, is that the TV cannot display 1080p.
Currently there is no way to scale down the mirroring - maybe in the future tho!

its strange because I can get the tv to show the xoom sometimes but i get that test box floating around even tho i can see the image. so it works kindof. little zoomed in and no way to disable the test feature. Really sucks because that was one of the main reasons I liked the xoom so much. wanted to play my N64 emulator on my tv from my bed lol. Tv was free so cant complain i guess. Just need to save for a newer one.

Pretty sure the output is 720p. It doesn't upscale.. it chops off the bottom to fit 1280x720.

Just spent all my money on a HD projector and the xoom so might have to wait for the bedroom TV...wall to small for projector in bedroom so it goes it the media room. Just need a nice media server for it. Haven't found one I like yet

Ive been trying to do this too and have discovered why its not working. Basically the Xoom does not output the required 5 volts needed to project the signal through the DVI adapter and onto the monitor. The only way around this is to add the 5 volts the best way I can see to do this is to purchase this (or something similar, I'm pretty sure there is a US made equivalent):

[Q] Can you change the HDMI Output on the Acer a500

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.

[Q] HDMI Out video issues

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.

No it does not. HDMI resolution is the same like display resolution.

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?

[Q] Note 3 HDMI Resolution

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.
