Hello,
I am trying to determine how to enable the Nexus 7 (2013) to allow screen capture through my Black Magic Intensity Extreme. I have the slimport accessory and can output HDMI to several HD televisions, but not to my Mac. Through my research there are a couple of things that could be stopping me:
1) HDCP encryption
2) Nexus 7 (2013) HDMI output, is it 1080p 60fps?
HDCP cripples the Black Magic Intensity extreme for HDMI video capture and the BM Intensity Extreme only handles HDMI output or input of 1080p 30fps.
I have come to the conclusion I need to root my Nexus 7 (2013), but I don't know crap about this. I am considering rootandroid.com doing this for me. However, how do I manipulate or remove the HDCP encryption and reduce the HDMI output to say 720p 50fps.
Is this possible and or does anyone have any other suggestions?
Are there other Android tablets that allow screen capture better?
I am successfully screen capturing my Galaxy Nexus, but the processor is an issue when running games, lots of lag?
thank you and any help is much appreciated.

I am having a very hard time deciding to keep this phone. There are things it does so well and others are a clear miss.
The HD dock kit (with the keyboard/mouse) brings up a massive limitation on this phone when connected to a HDMI monitor. Out of 4 HDMI monitors and TVs I own, there is not one that is an exact native resolution mode that is supported by this phone. The 720p modes come close to my 720p monitors but there is no support at all for 1080 modes.
This makes the video out look like crap on these monitors, like using S-video in or something. Most of the video modes seem to be from the old VGA output connector days like 800x600 1024x768 1280x1024 etc. Why?
The output quality is no where even close to what you are used to on your PC because of this. If you were lucky enough to have a monitor with a supported native resolution then mabey it would look correct. As it is, the text is painfully blurry to look at in todays crisp digital era.
Now that the desktop mode is unusable because of crappy video out mode support, major functions of this Atrix are gone.
Anyone else notice this?
I thought I should post this to give others a heads up on these accessories.
Hi guys. My GNex only seems to output to 720p when I connect it to the TV or he monitor. Does anyone know if it is possible to get the phone to output in 1080p? Thanks.

No. Unless ICS can "detect displays", it'll only display 720x1280, that the phone resolution.

hmmm I see. So why is it that I keep hearing people touting 1080p output . Can the GS2 output 1080i though? I've heard of some people who have. Really bizzare. My Droid X ran at 858x400 and outputted to 720p so something is up.

So the GNEX and Rezound both record 1080 but both can't output it? I'm confused. I though my GNEX could record it and then play it? I just got two days ago so pardon my absent of knowledge.
I can confirm that when using MHL to my LCD monitor, all video output is 720p. I tried playing some 1080p H.264 video files but the monitor still says 720p.
I'm beginning to think the GN output is always 720p over MHL.
Can anyone confirm this?
Something is amiss here.
With my Droid X, I can also output to my screen using the micro HDMI cable. The droid x also outputs to 720p; however, the resulting output only takes up a portion of the screen; there are black borders on the sides and on the top and bottom .
My Nexus on the other hand takes up the entire screen, which leads me to believe that this is behaving normally and as intended.

in this video you can see the switch to 1080p when playing a video file in diceplayer (1:35)... maybe the player has to support it?
No change with Dice player
I tried Dice player with a couple 1080p H.264 videos from Youtube. They all play at 720p in the software player and hardware mode.
I saw in that video above it switches. But my Dell 2408WFP monitor still reports 1280x720 mode.
I know 1080p works fine with this monitor and my PS3 using HDMI.
Maybe when you use this:

it works then
I was able to play a 1080p 11gig file on my phone through mhl to my TV and it displayed as 1080p. I was using MX Player and the Samsung mhl adaptor.
I will try this on my non samsung mhl adapter (monoprice verison). I have outputted 720p on my tv but never 1080p.

Are you certain that it was 1080p...?
I shot a test clip with the built in 1080p/24 setting on the camera and it would replay it at 1080p over MHL via the built-in gallery app. I think people run into two type of problems with MHL:
1) Cheap eBay MHL dongles that max out at 720p and won't uprez ever.
2) Non stock playback apps that don't call out to the MHL to up the rez.
Hmmm... I forgot I just got a 1080p plasma. Will have to test tonight.
Sent from my Nexus in Texas.
as far as I'm aware there will only be 1080 p output when playing a 1080 p video file? The rest of the time the display mirrors the phone display at 720 p. Is this the case and are there any games that can take advantage of the larger resolution?

Trying to find an answer for this. How do I get 1080p using MHL?

I've recorded a video in 1080, but it still plays in 720. MX player and stock player. Google play movies also play in 720.
Can't figure out how to get this to work.
Also strange, the edges of the display are cut.

I believe you can configure the HDMI settings to cut the (bottom) menus off, my TF300T have it, but I never tried it on my GNEX. I have a (announced as) 1080p MHL=>HDMI cable, tried some 1080p clips but never got my TV to show it above 720p. I'm crazy about it also, I really want to take advantage of FullHD with my Galaxy Nexus.
I'm using MHL Samsung adapter and Samsung 40D7000 tv, and when i play 1080p video through MX Player, TV information shows 1920x1080 resolution.

As of my current understanding / testing when connected to a HDTV / monitor etc via MHL, currently the ONe x mirrors the screen, so you get 720p. It doesnt look all that good (I have tested on a few native 1080p Tv's, and some look better than others.
I would assume that the hardware is easily capable of outputting 1080p (rather than just mirroring the 720p screen of the phone ?)
Any Devs, or any opinions as to whether this is something that could ever be expected from HTC, or possible to add to a custom rom..
I understand that other lower spec'd HTC phones can output 1080p (even though their screen native resolution is lower.. - Sensation XL or Evo 3D - sorry not sure which one exactly..).
I have to be honest I was pretty bummed when I connected it to the TV .. I just sort of expected it would do 1080p out of the box....
Also I understand that Media link HD only currently offers 720p mirroring of the screen.. Does anyone know if this is likely to support 1080 (maybe wifi bandwith limitation ..)
the lower spec phones i.e. the evo 3d that i own will only output 1080p at 24hz making everything laggy. also it doesn`t seem to be 1080p at all but simply upscaled by the tv itself. the images are not sharp at all but look fine from a distance. if i set the phone to output a 720p it will display at 60hz and image quality will be similar if not the same. if you look at the specs you will see that the tegra 3 cannot output to 1080p howver the tegra 3 + can. maybe a good dev will be able to help you out since i intend to buy a tegra 3 device too.

Could not stand still here but if you check nvidia's site it says that HDMI: 1920x1080 so it is capable of 1080p

Here's some info regarding what I've tried and what the results have been w/ my HTC ONE. Hopefully, it can help you based on what you're trying to accomplish. Maybe with some feedback, I can see if there's any work around. Obviously, this probably wasn't entirely part of the design team's intentions for this phone, but it's fun to try.
Using a 5-PIN MHL to USB Adapter:
INTERFACE: When I plug this in to my phone, I immediately notice scrolling through the app drawer is laggy. Do you? My adapter is from Ebay, and is about a year old. It looks like any other $10 adapter I see out there, but I wasn't sure if the newer ones are better.
INPUT LAG: almost non-existent. Pressing controls take action immediately.
MIRROR: TV is a true mirror of the phone.
MOVIES: playback stutters due to the MHL1.0 24fps @ 1080 restriction
GAMES: are playable due to low input lag, but again the 24fps bites you for any game (this is MANY) that does not support changing its resolution.
Using HTC Media Link HD: Ran the update to latest (as of Jun 19th 2013)
INTERFACE: Noticed right away that my phone remained butter-smooth while also transmitting signal to the TV.
INPUT LAG: felt like about 300ms.
MIRROR: TV is not a true mirror of the phone. I immediately noticed my phone was taken over, put in landscape mode and my app drawer was different.
MOVIES: Playback seemed smoother overall, with occasional hitching (not frequent enough to deter from use).
GAMES: Games are unplayable due to input lag. Noticed a softening effect and when not lagging, probably was a touch smoother in FPS.
Other Considerations:
Hook up to a non-1080p TV: Nope. Most modern 720p TVs support 1080i, and thus tell the phone to send it 1080 signal.
Hook up a REALLY non-1080p TV: Ok, ok... so get a 8+ year old TV, or an older LCD Monitor. Yes. Whatever resolution it supports at max will make the HTC One step down from 1080 signal and tada... movies, games and interface all become butter smooth over MHL to USB.
Change the output resolution in the app: This will work if the game supports it, but many don't. Movies? Does anyone know of a good movie app that lets you change the output res?
Root your phone, it's time for ElementalX's 720p MHL HDMI output tweak since this phone doesn't support MHL 2.0: Sure, but I'm trying to find a non-rooting method first. It looks decent. Ultimately, if I have to, I will, but I'm trying not to tinker this go-round. The phone is totally acceptable to me otherwise. On Sprint, he's just begun support for us and I'm keeping an eye on the thread to see better results from the pioneers first.

New finding: If your MHL adapter causes your TV to blink in and out from time to time, I figured out what it is: Turn off Mobile Data on your phone.
For me, when I'm on 3G at least, whenever it gets a data hit, the HDMI functionality cuts out causing a static, noisy output to the TV.
Fortunately Wi-Fi is OK. Untested yet with 4G.
About to purchase a Bluetooth controller , a generic mhl adapter from amazon that has been confirmed to work with the one , and a flash of the ElementalX kernel . Really hope I'll be able to play my N64oid and PSXe titles smoothly . Will definitely report back with results

With that great option to set to 720p you should be butter-smooth. Good luck and let us know!
Hey.
I am running the latest nightly of CM 10.1 on my HTC one.
I can not seem to get my mhl cable working. Once I plug it in my HTC one often shuts down. The cable isn't faulty. It works like a charm with my galaxy nexus.
Sometimes I see a mirror of my screen but it is with a really bad resolution. Sometimes it flickers and shows a picture on and off. Mostly it freezes and then shuts down. It's really annoying.
USB OTG also doesn't work. The frequency of getting a bad resolution for a little while before it shuts down worked better after I disabled USB debugging in my developer settings.
Any thoughts? Workarounds?
Thanks in advance.
HTC one. CM 10.1
Turn off any form of motion control, as that'll cause quite a few issues as well.
Correct. Thanks a lot. I turned off auto rotate and then it worked. Didn't think of that. Now the mhl HDMI setup runs flawless without lag.
HTC one. CM 10.1
It's just me or image quality it's not that good? It's not the same as computer connected with HDMI? It seems it lower bitrate or diminish image quality. I am not talking about 24 fps limitation...
Does MHL adaptor quality might have an influence, or it's all the same?
Does this new Nexus support MHL ? or some protocol that allows us to view screen on HDTV? What cables would I need? Does it allow full mirroring?
What's the deal with wireless display? Does it work well? What are the best devices to use for onscreen? Can Chromecast do full mirroring of the device?
Sorry, I'm out of date on this subject. Thanks!
The 2013 Nexus 7 and Nexus 4 use Slimport instead of MHL. I don't know about wireless display options. Chromecast does not support it...for now.

I have the HDMI dongle below which uses Miracast. Miracast is built into the Nexus 7 FHD in the /settings/display/wireless display. Just turn on wireless display and it finds the dongle and mates via wifi direct. Everything on your tablet goes straight to your TV at HD including sound. The latency is slight but not too bad. The main thing is that it works right out of the box and works well. I use the dongle with my Nexus 7 and a VGA adapter to throw powerpoint presentations up on a projector using Presentations Mobile from the play store. It works great. Everyone marvels at my ability to walk around the lecture room with my nexus 7 and run the presentation, only needing to look at my nexus for the next bullet point. The dongle hooks up to the projector via a VGA to HDMI adapter and the projector found the device without a problem.
The only thing you will notice is that the 1920x1200 Nexus resolution when thrown up to a HDMI television screen will not fill the screen totally. I tried changing some display and density settings as in this post. It helped on the TV but made no difference in the VGA / projector image. So, if you want a fuller image on your HDTV you might want to use the Terminal Emulator and run the display and density commands in the post above. However, it isn't absolutely necessary as the HDTV image fills up about 90% of the screen if you can stand that. Hope this helps.

Netgear PTV-3000 (Push2TV) works using Miracast (tested) in both tablet portrait and landscape modes. You connect the PTV-3000 to your HDMI port on HDTV and use Settings, Display, Wireless display on Nexus 7 (2013) (only, not Nexus 7 1st gen). But the quality is lacking. Another similar Miracast device is Bestbuy Rocketfish - Miracast Video Receiver, Model: RF-WFD301. It works, but I have not yet tested. I got last week for $50 off on BB special, cost $29.
Otherwise use Slimport cables, but get a recommendation first. Quality of Slimport has been reported both good and bad. I did not test Slimport. MHL does not work.
Chromecast can only do full mirroring of PC, like Windows 7 & 8, Mac, Linux. You must run Chrome Beta and add Google Cast plugin. But, Chromecast does not work (yet) with phone nor tablet. Chromecast broadcast of PC full screen is experimental. I've tested on Windows 7 & Mac.
Good luck
