[Q] [ROM] CM11 and HDMI - Nexus 10 Q&A, Help & Troubleshooting

I am trying to use my HDMI output on a VGA projector and only get a black screen, the projector responds to locking / unlocking the tablet's screen by switching from neutral to black screen, though.
Is HDMI implemented in the latest update (11-20140624-NIGHTLY-manta) or is it my setup causing the problems?
I'd appreciate any answers!
Best,
dersami

I use HDMI port on CM 11 nightly without any problem on my Samsung TV.
I just use Screen Standby (found on play store) to block locking but to just switch off tablet screen. I mainly use this for spotify whitch don't block locking and stop playing by hdmi when N10 is locked.

Hi,
I don't know if it'd work on a VGA projector, could you try it with another device? Or plugging your Nexus on a HDMI TV? Because it's very likely it's the projector adaptor that isn't really working.

I don't have the means to test this on a true HDMI device :/ Does anyone have a recommendation for a working HDMI to VGA adaptor? I am currently using the Cable Matters Active Mini HDMI to VGA Male to Female Adapter.

I did some more testing and tried to change the resolution using
su
wm change size 1024x768
in the terminal.
Although this changed the resolution on my device, the projector still only shows a black screen, even after reconnecting said adapter. Could it be that I need to change the density or refresh rate? If so, what value for density might work and how do I alter the refresh rate?

[Q] Acer HDMI - special settings?

I have an A500 with the Acer stock rom on it (3.2), and I'm having problems getting the HDMI out to work. Is there a special setting somewhere that sends the screen output to HDMI? Or should it automatically appear?
I got a micro HDMI to HDMI adapter off of eBay, so I don't know if that's the cause of the problem. I know the HDMI on the TV works because my XBox works fine on it.
I would appreciate anyone's insight into this problem.

Have you tried turning off your tab, plugging in the HDMI cable to both your tab, and TV, then booting up tab?
It should just work as soon as it's plugged in. You'll see a notification that an HDMI display was detected or somesuch. My A500 had a loose HDMI port so it would flake out with the slightest touch. Cables are cheap, so it may be worthwhile to get another cable from a place like monoprice.com and see if that makes a difference. If not, it's either the device or TV. Maybe a friend has an Android phone with micro-HDMI you can test with?
I found plugging into tv first then connecting to tab worked best, before that I only had a blank tv screen... Seems the A500/501 needs the tv connected first, at least mine does...
mine to just works..
WELL it does on my SAMSUNG SMART TV..
ON MY LAME BUT Huge screen SANYO.. (DONT LAUGH IT WAS ON SALE) tv in the living room i have to sometimes plug the cable into the tv.. set the tv to hdmi 4.. IT WILL ONLY WORK ON PORT 4 .. then when i have black screen saying no input found or something like that i plug in the tablet.and all is well..
ALSO PAY GOOD MONEY FOR THE CABLE.. THE CHEAP TINY Connector is not equal on all cables my iconia only works on the gold plated high end cable
i use the same one as i do for my cell phone...
ACER WAS LAME BY PUTTING SUCH A SMALL PORT. there is room in that spot of this tablet for atleast a mini port if not full size I hate micro ports...
I bought a micro to standard HDMI cable (by PNY) last night at Staples and it works fine. I got 10ft for $29.00, compared to the Monster micro 4ft for $39. It worked fine at the hotel I was at on the flat panel in my room. No complaints from me.
I'm surprised at the diameter of the cable, as it is very thin. But, it works! Hellooooo Netflix!
I'm about to try it at home on my old Sony XBR...
Cheers!
I bet he's using a Westinghouse TV if I'm right for some reason the Westinghouse brand doesn't like any android hdmi out this goes for my a500 and my evo. Mine doesn't work and I have had it working with my Sanyo as everyone mentioned just by plugging it in

I also had a problem of not getting my Westinghouse TV, that is only a few years old, to recognize the HDMI input from my A500. Tried everything and it didn't work, but the A500 works on my other three tvs.
I plugged my A500 into an older Sony 52", using the side-mounted HDMI input, and it 'just worked'. Mind you it freaked out momentarily when I flipped the tablet around and the screen auto-rotate kicked in, but once I oriented the tablet in it's normal "upright" (volume buttons on top) position, everything looked great.
On this same topic, I noticed that standard/full-sized HDMI to HDMI Micro cables are hard to find in the retail chain, so I bought mine (dirt cheap prices/shipping and excellent quality) from monoprice dot com.
Really? Huh. Rotation is disabled for me when i plug it into my 25" hanspree
And it 'just works' for me too

[Q] No HDMI output to LG 42LD420 tv!

Hello!
Just got my Nexus 10 and I tried to connect the Mirco-HDMI out to my LG 42LD420 tv.
However, screen is all black and nothing happens. When I connect to my new PC screen HDMI port the image is mirrored instantly and it just works...
So I guess theres some new standards in Micro-HDMI that my TV doesn't support?
Just wanna clear this problem by making sure its my tv. And btw, other devices works just fine on the tv HDMI port...
Thanks for any info.
Simon
Whenever HDMI has problems it's usually HDCP that is the culprit.
Thanks! Googled some about it and I realize the problem New TV then I guess or try with some adapters to analog input...
I just ran into this the other day myself with a Samsung TV. I thought maybe it was the TV was only capable of 720p or something...
I'd get sound through from the N10, no picture though.
Also tried an MHL cable with my GNex and nothing as well.
Both devices work no problem on either of my PC monitors, and the PS3 has no problem with that cable/port on the TV.
Are there any workarounds?
My quick search indicates that it's possible that it can be cable specific? ie. Will work for some devices but not others? Does that even make sense?

[Q] TV adaptor for nexus 10

What kind of an adaptor do I need to connect my nexus 10 to my TV (it's an older TV, not flat screen, not HD. I don't care about losing the HD, just the size.)
Thanks!
Micro HDMI to HDMI, DVI, or maybe even Component (not 100% sure on that). If the TV doesn't have any of that, then you'll likely need an Analog converter to go from HDMI to VGA, Composite, or RCA.

Check your TV. If it has HDMI, you want micro-HDMI to HDMI. If it doesn't have HDMI, but does have DVI, you'll want that.
If it has neither HDMI nor DVI, you'll need a new TV Or an HDMI to analog converter.
Nexus 10 to CRT TV connection
I have a nexus 10 tablet running stock 4.4.2. I bought an hdmi to rca converter from amazon.com and a micro hdmi to hdmi cable so that I could hook up the tablet to my old sharp crt tv. When I plug in the connections I am seeing a stripe coloured screen that says 'no signal ntsc'. when i turn the switch on the converter to pal it says 'no signal pal'. Could you tell me why this is happening and if anything could be done so that I can see the content from my tablet on my tv? Do I need any software/app installed to make this work? The only ports on the tv are the composite rca ones. I know the tv is old but its its 55 inches and in perfect working condition so I really don't want to purchase another so please if there is anything you know that would help I would be more than greatful.
My setup: the microhdmi to hdmi cable plugged into the micro hdmi port on the tablet, then the rca cable connects to the back of the tv and the rca ports on the converter. Should work?? Help me please. Thanks in advance.

HTC ONE OTG not supported/MHL playing up

Any info on this would be well appreciated.
Don't know if this is already covered somewhere but I can't find it. I'm well gutted about this, Just tried watching a film on HTC ONE with OTG cable and it doesn't work. I get a warning notification saying " unable to charge device, please use supported charger " Gutted. I thought this would of been covered since the one-x supported OTG when it got 4.1 update. Also, don't know if it's related but the MHL (an official HTC 1) isn't working properly either as it did on my one-x. It wil be playing fine for 20/30 seconds and then cuts off for 10 seconds then comes back on. It's does this repeatedly which makes what ever your trying to watch - unwatchable.

It supports OTG
Haven't tried mhl, but otg works fine here.
Tried it with my memory sticks and fiio dac.

Seem to be working now. Must of been the memory card adapter I tried, tried another one and ok now but still getting error notification " unable to charge device, please use the supported charger " Don't know what that's all about. Keyboard and mouse work fine with OTG, never tried them before.

Isn't the one purportedly MHL 2.0? Maybe the adapter needs to be different...

I just tried MHL on my One using the official HTC M490 adapter (NOT the M500 which I think won't work). I have no problems at all with MHL. It is stable. I don't know what difference MHL 2.0 makes, but I did notice that the phone seems to be capable of outputting something different to MHL out, vs what is on the phone screen.
For example, and I have no idea why, I seem to have a free copy of Thor on the phone under the HTC Watch application (freebie?). I found that when I choose Thor as the film, the phone screen is showing a synopsis, while the TV is showing a still frame from the movie. However, when actually playing the film, both are showing the same thing. Nevertheless it is a good indication that dual screen gaming applications may be possible for example.
Also tried the OTG using a Samsung usb adapter. No problems functionally but I can confirm the misleading error message about not being able to charge the phone. No problems accessing the USB storage though and Gallery automatically will find pictures on an externally mounted SD card.
HTC M500 adapter has 12 pins and was the adapter for HTC tablets (Flyer and Jetstream). The majority of connectors use 5 pins, except Samsung (SIII and Note 2) that uses 11 pin, which allows for MHL and USB OTG simultaneously.
Regarding MHL 2.0, it has the ability to pass 1080p video at 60Hz (up from 30Hz of MHL 1st generation) and charge up to twice as fast. Samsung SIV has it, but I haven't find anything official that shows HTC One also has it, or for the need of a different adapter.
All the MHL adaptors i've seen (mine included- Cablesson) have a micro USB slot so you plug in your charger* to that, then the device to your phone, and it charges as it outputs.
Are you all doing that, or trying to output with no charger attached.

I have no problems but to confirm the adapter won't even start-up if you don't connect the charger...it is totally ignored. I am assuming the original poster either has a bad USB/MHL port on the phone, or the adapter is slightly out of tolerance with its connections hence working on some phones and not others.
I've bought an adapter on ebay for my One X. Besides ths usb charging port having issues, it messed my One X usb port - it only worked with the adapter pluged in. I had to reset One X. So, mhl adapters can be really a mess.

First day with phone today so briefly trying lots of things, I had pre-bought cheap ebay MHL adaptor and tried it with a few youtube videos seems to work OK (confirm you must have a charger micro-usb MHL).
It did give about 20 secs of white snow interference at start almost as though it was tuning in channel but steady after that.
More investigations to follow I think.

How did you get on after more tests?
can you link me to the one you purchased if all worked fine please
if anyone else has a 100% working MHL to HDMI can you post which one and where to purchase.

Sucks that I don't have mine yet. I have two different MHL adapters I could try.
I just experienced the original "HTC AC M490" MHL-Adpater with my HTC One (Stock ROM).
It was working straightaway, but the device display as well as the TV screen where a little bit slow and choppy.
Is it possible to change some settings (like resolution or frame rate) to improve the performance?
THX
Edit: Is it MHL 2.0 ? (Regarding to this thread it seems to be only MHL 1.0)?

No, it isn't.
The S4 will be the first MHL 2.0 spec device.
Is there any way to set the output resolution manually to 720p?

With a custom kernel you can do this. Flar2 did this for the one XL, I see he's starting to migrate over here.

Yes obviously plugged the charger in aswell with the MHL. The picture is perfect. It just play's for 20/30 seconds then cuts out for a couple and just keeps doing that. Even though the OTG works I still get the error triangle in the notification bar, which I don't on my ONE-X, but I can put up with that.

Trying to use an MHL lead

These phones apparently support MHL, but I can't get it to work. I've got a mini USB to HDMI lead, but don't get any output at all. How do I make it work, is it supposed to just show my screen as soon as I plug it in, or do I have to use an app? Does it have to be powered or something?

What kind of MHL cable is it? It needs to be an 11-pin one (made for S3/Note 2/S4).

What device are you trying to use it with? Does it itself support MHL?
I just thought any tv would display it through HDMI as an input, didn't realise the device I connected my phone to mattered. Coincidentally though it is a Samsung. And aren't mhl cables all the same then? Samsung made their own to be arkward?
Think you need mhl 2 for the s4 and for it to display 60hz
