[Q] Is there a way to limit (up)scaling on HDMI out of a Nexus 10? - Nexus 10 Q&A, Help & Troubleshooting

Is there a way to limit the (up)scaling on the HDMI out of my (rooted) Nexus 10? To be more precise: If I connect the Nexus 10 via HDMI to a TV set, can I tell the tablet to limit the signal on the HDMI out to e.g. 720p even if the TV set accepts signals up to 1080p?
The reason I ask this is that I'd like to play low resolution content on the tablet (having lowered its virtual screen size to match the content's resolution) and let the TV set do the upscaling.
Just to be clear: This question is NOT about how to set the (virtual) screen size (which can be done using the "wm size" command)! It's about imposing a user defined limit on the scaling the Nexus 10 does on the HDMI output.

[Q] HDMI Output Resolution

Hey All, I looked for my answer elsewhere on this board but couldn't find the answer.
I am trying to set my Xoom up at work with a Bluetooth Keyboard/Mouse and output the screen to my monitor. To simulate my current work environment. The monitor I have only has VGA or DVI inputs. The cable I have is Micro HDMI - HDMI. So I bought an HDMI - DVI converter. When I output to the monitor, the monitor resolution will not match the Xoom so I don't get the entire screen. I have to scroll up or down to get the entire screen. I verified that the monitor supports 1280 x 800 but for some reason when I plug the Xoom in it goes to 1280 x 720 (720P?). I am guessing somehow I need the monitor to be 1280x800 so it matches the Xoom? I don't see a manual configuration on the monitor to change that. It seems to auto-ajust depending on what is plugged in. So I guess my question is; Is the issue with the HDMI-DVI converter or is the issue the monitor? This is very problematic because I need to Remote Desktop into servers and/or workstations as a proof of concept.
The Xoom will chop off the bottom 80 pixels to get 1280x720 (native 720p resolution)

Yeah, I understand that (I assume the bottom 80 pixels are the task bar and such for android). That isn't quiet the issue. I think it is something to do with Pocketcloud application that I am using to RDP. When I set my PC resolution to 1280 x 720 and VNC into my machine the resolution is just fine (setting Pocketcloud to "Automatic Resolution". Doing the same for RDP it defaults to 1280x756 for some reason).
i want to say that 1280*800 and 1280*720 is similar with our eyes. so i think u don't need to care about such a litte gap.

My experience is that it will default to whatever the maximum resolution it detects when you turn it on with the HDMI connected.
Are you getting a cropped 1080p desktop on your 720p TV? One of my HDMI ports is busted on my TV and that cropping happened to me when I tried to connect my Q to the TV via an HDMI -> Component converter. Plugging it in direct to HDMI with the TV already on when I booted it fixed it for me
i am having a similar issue, all boxes are checked and it is situation normal, but it cuts off all edges, may swap HDMI ports later

[Q] MHL 2.0 limit to 1920x1080 30p ?

Check your tv manual. Some tv have limitation on inputs and/or modes. For example: mine requires to be switched to pc mode to accept higher refresh rate.

[Q] Can't display 1080p?

Hi Everyone,
I just got a Nexus Player and connect to my TV.
Everything is good except the resolution stays on 720P.
My TV does support 1080P, since all other devices use 1080P resolution.
And Nexus Player should also support 1080P.
Does any one know if there is a way to manually setup the resolution on Nexus Player?
Thanks a lot.

The TV screen resolution will still stay at 720p, but the Nexus TV screen resolution should be 1080p ! Their is a way to verify this via the app Screen Specs found at the Google Play Store https://play.google.com/store/apps/details?id=com.MTMDevelopers.ScreenSpecs ! If you cannot get this app let me know. Another way to verify this is via the AnTuTu BenchMark app!

Hi, Thanks a lot for your reply.
However, if the TV screen shows the signal is 720p, that means nexus player sends 720 picture to the TV via HDMI, as a result, you will see a 720 picture, which I expect to see a 1080P picture.
I have no idea why these app shows 1080p in the system, but as long as it doesn't send 1080p to the TV via HDMI, we can't get 1080 quality, right?
If the TV is 1080, but received a 720 signal, that means it is not pixel to pixel picture, the picture is not clear.
Is there a way to force the player to send 1080P signal via HDMI? Will Root support this?
Thanks a lot.

Everything you are saying is correct, but the Nexus TV Player will not override the built in 720p TV Screen resolution ... Yes, the Nexus TV Player is sending a 1080p signal to your 720p TV, the 1080p signal is being down graded to 720p ... In order for you to get full 1080p screen resolution from your Nexus TV Player, your TV will have to support 1080p screen resolution.
Now if your TV supports 1080i/1080p and you have a cable service, their is a way to go into the cable box to change the screen resolution. Any other way, it would have to be changed via the TV settings.

Unless I'm mistaken you appear to be misunderstanding the original issue, his TV can support and other inputs work at 1080p with it, but for some reason he suspects that his Nexus is only outputting 720p, at least that is what his TV thinks its getting.
This appears to happen to other people also, without a decent resolution, hoping that M preview 3 will contain something positive.

I get the same issues. I purchased two Nexus players today, primarily for running Kodi.
The first of these is connected via a Home Theatre receiver to a 1080p TV and is displaying the Nexus Player content at 1080p.
I have a second home Theatre Receiver connected to a 1080p projector and is using the following resolutions:
[li]720p : Nexus Player running Android 5.1.1
[li]1080p : Apple TV 3
[li]1080p : Sony Bluray Player
I also tried swapping the inputs to the Home Theatre receiver to see if the output resolution changes from the Nexus Player. The Nexus Player is refusing to show the content at 1080p. There is also no way to force the output resolution. It certainly makes the viewing experience terrible for HD content on the Play store or via Kodi.
The Nexus Player and Android TV really needs work to improve settings available for manually configuring the output resolution.
Hi Guys - I'm also stuck at 720p output from my nexus player. Have there been any developments on unlocking 1080p?
Does anybody know if there is a fix to this? I just bought a nexus player and it is outputting 720p to my TV. I've searched at various websites and I couldn't find any solutions to this. Any input is appreciated. Thanks!!
I'm having the opposite issue.. hooked up to a cheap 720p TV and it outputs 1080, which the TV fails to convert properly, so I loose an inch or so of viewable screen on many apps (launcher seems OK?)
..found some posts that suggest "overscan calibrator" can fix this problem:
http://forum.xda-developers.com/attachment.php?attachmentid=3234854&d=1427641822
..It worked for my particular issue.
if someone cant answer this problem. I'm taken it back because the picture is horrible
same issue here ... running N preview
tried many hdmi cables
I can't even SEE a picture, because I cannot reset resolution from 1080 to 720 . And the many many many responses on xda have been deafening on this issue.
Is there ANY way to manually set resolution??????
Does any alternative ROM do this? Does the new developer preview? Can it be done with any 3rd party apps like overscan calibrator? Any sort of editor?

Connecting Moverio BT-200 to Windows 8 directly with Miracast

Hi all,
Did anyone succeed already to make the Moverio BT-200 be monitor for a Windows 8 PC using Miracast?
This is what I tried already. Apologies for not adding the weblinks, but the forum rules won't allow.
1) The problem is that the BT-200 has a qHD resolution of 960 x 540 which is not supported by Windows 8. Therefore, I set the DownScaling bit to 1 in the registry. (Start Regedit, find all occurrences of Display1_DownScalingSupported and set the value(s) to 1).
2) I then started Miracast on Windows 8: go to right bottom corner, in the menu select "Devices" / select "Project" / click the dimmed "Add a wireless display".
3) On the BT-200 start a "Moverio mirror" session. It takes some synchronization effort to get the two devices see each other and get connected (have some patience while trying).
In the end I got the two connected, but I only get a black screen on the BT-200. When I try to configure the modes (right click on the desktop / choose "Screen Resolution / click "Advanced settings" / "Adapter" tab / "List all modes" button), the only mode shown is 1280 by 720 at 60 Hz.
Any way how I can fool the modes into a 960 x 540 configuration? Even better: how can I set up the Miracast connection as primary screen at startup?
Oh, and yes, I do have an Epson Wireless Mirroring Adapter, but it's not showing me the proper graphics either. for that reason I tried making the direct Miracast connection built-in into Windows 8.
Any pointer greatly appreciated.
Kind regards.
Hi,
I don't have any of these devices yet. But I am considering purchasing them. Just for screencasting what the user is seeing. I understand that it probably cant show the "augmented view". But, does the mirroring adapter sink function work ? Can I atleast see whatever is being cast to the user on a big screen using this adapter ?
Thanks.

Hi aaaku,
Yes, the mirroring adapter that is sold with the BT-200 works pretty well, but it's a clumsy device that very much limits the useability of the BT-200. While the BT-200 is battery operated, the Wireless Mirroring Adapter needs an adapter. Connecting it to a power bank works, but it uses quite some energy. Moreover the double interface (device to Mirroring Adapter, and then the Miracast connection between the Adapter and the BT-200) takes quite some time to set up properly. If you lose connection on the go, it's a guessing work where you lost the image or where a cable got disconnected. All-in-all it's not that smooth as you would like it (for me it turned out a showstopper even), and that's the reason why I wanted to Miracast from a Raspberry Pi directly to the BT-200.
As stated higher another issue is the not-quite-standard 960 x 540 resolution of the BT-200. Yes, it's possible to connect a Windows PC to the Wireless Mirroring Adapter, and then display the image on the BT-200. The BT-200 will even show a very clear image even. Since 960 x 540 is not recognized by Windows (or Linux, tried that too) it will display at a higher resolution, and the Mirroring Adapter will do the 960 x 540 translation. Read: some resolution is lost. It e.g. makes selecting menus and doing configurations under Windows 8 rather difficult as it's pretty hard to read the menus. For image viewing it works well, though. The image is bright and clear, and the display does what it promises.
