MK808B changing default resolution - Android Stick & Console RockChip based Computers

I purchased the MK808B but my 1080i HDTV (samsung HP-T5064) does not show any image ("Not Supported Mode") probably being incompatible with the default 1080p output from MK808B. At the moment I do not have access to another TV or monitor with 1080p to be able to change the output to 720p. I am looking to purchase a HDMI to DVI-D adapter to hook up the MK808B to one of the monitors I have but not sure if that will work. Any suggestions ?
Thanks !

Go to freaktab.com and find one of the Finless ROMs for it. Flash that using the readme instructions, and it will explain how to choose the right kernel for the setting you want. I think 720p is default.

Thanks for the suggestion. I flashed the Finless ROM 2.1 with the default 720p setting. My TV still does not show any image ("Not Supported Mode"). Maybe the problem is with Samsung TV being 5 years old. I, off course, cannot check the actual output from the device to ensure that ROM was flashed correctly.The HDMI to DVI-D adapter should arrive sometime next week and I will then try connecting the device to my computer monitor.

MK808B changing default resolution-SOLVED
I managed to get the TV to recognize the MK808B by flashing Finless ROM 1.7. I had previously tried 2.1 with default 720p resolution but the it did not work. Not sure why, but for the time being I will stay with 1.7.
Thanks for all the help

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

DVI and USB Audio?

Well, since I don't have a TV with HDMI, I was really hoping I could run my OUYA on my computer monitor with an HDMI to DVI cable. I do get picture, but the resolution is horrible. I've contacted support about this, but have not received a reply in over a month. Apparently I am not the only one with this issue as it can be found all over the support forums. Not sure if it's a resolution issue or HDCP issue or something else, but I'm hoping some enterprising dev can figure it out.
On the same note, since my monitor doesn't have speakers and an HDMI audio extractor is about the same price as the OUYA, it'd be nice to be able to use a USB DAC to output audio to my desktop speakers. Apparently the SGS3 has it enabled, it just isn't in the stock android kernel yet: See Android Issue 24614
Anybody working on this or heard directly from OUYA support?

The resolution isn't an OUYA specific problem, it's the same on many devices. I believe it does have to do with HDCP. I know there are some people out there with similar situations as you that have a converter cable that works, but it's not very common. IMO this is something I believe they never thought would come up was a problem that seems to be more common than not.
And yes, any type of converter box or audio splitter is going to cost you. the HDMI to Component box that I was looking at that I heard works costs 150, so it's not really worth it.
As for the sound over USB, I haven't heard of that yet for OUYA, but I know it was actually part of android starting with 4.1. That does not mean it works with the OUYA, however, as it seems only a few phones/tablets actually have the ability. If you have a micro USB to USB adapter, you might try it through that, but other than that not sure if there's any options.
I was really hoping this thing would have a AUX port, but it doesn't. I know there's some devs working on pushing sound and video from android over a network, but it's still in early stages and as far as I know no one has it working yet.
Really hope someone finds a good workaround. I don't particularly want to buy a TV just for this little box.
Well this is interesting...I just installed CWM, and while in recovery it shows full screen and looks rather nice. This must mean that it's not an inherent problem with my screen or connection, but is something do do with the software. This makes a work-around seem feasible, no?
Just found a reply in the StockPlus thread in the Dev section, but thought I'd repost here since I don't have 10 posts yet and can't reply there:

This one, from what I understand it's Android compliant, so it just needs the standard USB Audio modules. I know the Nexus 7 got it working with certain kernels that had the necessary modules loaded. Jellybean was supposed to make this easy, but it's been hit or miss on which ROMs have the files.

I have the same USB audio adapter and it's not working for me either. Really hoping someone cracks this nut.

The issue with this is that the Ouya looks for screenmodes of 1920x1080p and 1280x720p in the monitor EDID.
Failing this, it reverts back to a letterboxed 640x480 screenmode.
There's a thread here with more info.
I have an old monitor that runs 1600x900 I use it on next to my computer just to root. If I could make it use 1280x720 and my logitech usb sound card I'd get more use from the ouya as it's now hooked to a shaerd TV. I can run my PS3 and xbox on the monitor at 1280x720 and get sound from the av outputs.

Good info on that thread, too bad nobody has seemed to make much progress though. My monitor is capable of up to 1920x1200 and supports 1280p and 720p resolutions. Sounds like the solution is either to get the EDID talking correctly, or hack in a way to override the OUYA settings and change the resolution manually.
I am running a HDMI Audio Switch (Ligawo HDMI Audio Switch ~35€) using a hdmi-cable between ouya and switch and a hdmi-dvi cable to connect the switch with my computer monitor. The switch comes with a cinch-output that is connected with my 2.0 Amplifier.
Funnily enough the switch also solves the resolution problem, I still have when connecting the ouya with my monitor via hdmi-dvi cable. Now my monitor runs brilliant on 720p.

I bet the switch provides some EDID spoofing. Most do in order to keep display sources from freaking out when the display is disconnected and reconnected.
Glad to hear it works...hopefully that means it's less of an issue with HDCP and more to do with EDID. I'd rather not have to buy a switch that is almost as expensive as the console itself when DVI and USB audio (in my opinion) should work out of the box. Hopefully the OUYA devs get around to adding support, but I have more hope for the XDA chefs.

I just bought such a Ligawo device, and whenever I plug in the HDMI-DVI cable, the OUYA seems to turn off sound via HDMI, seemingly because al that digital stuff is so "clever" it knows that DVI doesn't do sound. At least that's what I think, and one of the customer reviews on the device on Amazon (the link I cannot -yet- post here, grmbl) confirms it, kind of.
You don't have that problem?

[Q] Video output doesn't work with my TV

Hello, I've installed the cm-10.1.2-steelhead.zip on my Q and there is a problem with the video output for my TV. The interesting is that ClockworkMod works fine on that TV, only the CM itself has no video output.
I've tested on a different Tv and CM is working fine. How do I change the default video output of the CM to the same as the ClockworkMod?
Do I need to change the kernel image or just change some option would be ok?
Thanks
Hi! I have the same issue. My Q is working with the factory image, but CM productes an "invalid data" error on my TV. I know that the factory image uses 720p, and CM outputs 1080p, but my TV should be able to handle it.
Could be that there is no audio feed from clockwork, and you are getting too much loss with the cable you are using. Had that issue in the beginning. Try using the shortest possible cable arrangement and see if you get success there. You are sure you're making it all the way into cm right?

Hi! Thanks for your answer
I'm not sure about the cable. I have been using the one came with the device. It's possible that it's not working properly, I have to buy a replacement to find it out.
Until that I got cuirous. You said that "Could be that there is no audio feed from clockwork". Are you suggesting that the recovery only works for me because it sends less data (since there is no audio output)? I quickly downloaded a different CM11 image that uses analog audio output instead of HDMI to see if it works. Unfortunately it wasn't successful. It still doesn't work
I have a theory. What if CMAs far as I know the factory rom uses 720p output. I'm guessing then that it's a fixed resolution, there is no autodetection involved. However CM tries to figure out which resolution to use. What if this fails for some reason, and tries to switch to a resolution not supported by my TV? I guess it could be tested by making CM use a specific resolution. I just don't know how.
Does anyone know how to set a fixed resolution instead of letting CM to figure it out? I have access to the device via ADB (through recovery) and I can modify the kernel parameters in the boot image, but I'm just not sure what to modify exactly.
Hello
Here's a bump
So, my Nexus Q is not working with my HDTV, but it works well if I plug it in a HDMI display. My TV says "Invalid Format". I brought another hdmi cable to test, no luck.
It's only a problem if I'm using CM (every version I could find fails), the stock rom works fine with my TV (but the stock rom is not really useful)
Any ideas? I have a completely capable device to be my media center, and I don't know how to make it work.

I was able to enable root shell using another HDMI display and connected on my TV, but the wm tool (adb shell wm) that changes the resolution does not modify anything, it actually keep the output on "not supported" even on small resolution (640x480) and low pixel density.

[Q] Only getting 480p when connected to Optoma GT720 HD projector

I could use some help.
I tried resetting back to factory settings. I originally had it connected through my yamaha receiver. I thought that was the problem but then I connected it directly to the projector. Still the same result. stuck at 480p. I've tried it on my 720p plasma and it works fine. There are no video output settings I can change apart from optimize for resolution or framerate in developers options.
Tried switching HDMI cables also.
There is no options on the projector to force resolution, since it auto detects resolution.
After more troubleshooting, seems this is an HDCP/EDID issue with the nexus player and projector combination.
Google Play Movies will only play a blank screen with sound.
Tried switching to a 1080p monitor with a movie playing and it shows up fine on the monitor. Auto switches to the correct resolution and keeps on playing while hot swapping the cables.
I tried chromecast on the projector and it works fine at 720p resolution.
At this point dont know what else I can do.
I've had problems with my Acer H5360 projector, which apparently displays the wrong black levels. It's also had EDID problems before (the chip was not read-only, and got corrupted) and different devices handled the default fallback differently. Is it possible your EDID is corrupted?
I dont belive the projectors edid is corrupted because my receiver lists all the capable resolutions it supports. Chromecast works fine, ps3 auto detects all the resolutions including 3d. Only having the issue with the nexus player. It defaults to 720*480 60hz. I coonected the nexus player to my monitor and it automatically showed 1080p. Flashed the latest update that was released. Still no luck when i reconnected it.
If you take a look at the other thread, the EDID for that guy's system showed that it supported 1080p, but the first timing it declared happened to be a lower resolution, and the Nexus Player just picked that one and went with it, not checking for a higher supported resolution.
That should be something they can fix with a software update, so hopefully they're aware of it and maybe we'll get an update sooner than later.
Got the same problem, same projector, my workaround was to use my old google tv (sony nsz-gs7) and use it as a bypass so my projector would detect it's a 720p projector -_- until they find a workaround....
Did anyone find a solution for this problem? Having the same issue on my Optoma.
Thnx

4k tv problems

Hi all,
Recently bought a shield to go with my panasonic cx802 4k TV..
I plugged it all in booted the nvidia logo popped up then black screen... Nothing I tried swapping ports restarting etc nothing.., so I hooked it up to monitor and went though new install changed the HDMI res setting to 720p un plugged and went back to my pana which now did display a picture... Problem is I cannot select a res higher that 720p which I'm finding really annoying.. Can any one help?
Guys I know it's my first post I'm not a total noob.. Just started a new name..
Would a fix for this be to install a custom ROM where I can more control??
Any advice welcome
You shouldn't need that! Btw have you got other sources hooked to your tv, BR player, AND have you tried the sat channel in 4k?
Edit: Saw a reply from @Koying regarding you must not uncheck SURFACE rendering but that was regarding Kodi, to have 4k working. You didn't mention Kodi, though!
Edit2: Have you tried disabling Cec control, if you had it enabled before?

I tried a brand new cable 2.0, same problem.
I reinstall my TV and my shield TV, same problem.
On a french forum i found someone talking about an Edid corruption, but i don't know what that's thing.
I couldn't test on another screen because i don't have one. I can read 4k movie with my popcorn hour on the same HDMI port, with the same hdmi cable as the shield TV.
Do you have a lead about a solution ?

EDID is the signature the TV send to connected device so the device know what the TV can do.
So if the EDID is corrupted or unknown to the device it will default to 720p or 1080p. IMO
Maybe you can perform a firmware upgrade on your TV and see if their will reset the TV itself . Check their support site.
Good luck.
Extended display identification data (EDID) is a data structure provided by a digital display to describe its capabilities to a video source (e.g. graphics card or set-top box). It is what enables a modern personal computer to know what kinds of monitors are connected to it.
Thank you, i did perform a firmware update just before the problem happen on my TV.
Maybe a downgrade could be a solution, i have no idea on how i can do that on philips TV
I tried to do a full install with nvidia img, but i never pass the "please wait .." steps
i could perform a hard reset of my tv, reflashing the first version of the firmware.
Still the same problem.
I will ask Nvidia for a RMA

Filty21 on another forum found a solution here's the solution, i'm trying :
I had the same problem: you have to factory reset your shield on other device like xbox one pass-through. I explain:
First let the Shield connected to your tv and try to factory then at popup confirmation click ok.
Second disconnect hdmi cable to connect it at an other device (xbox or receiver...). Let the shield in this state during 10 min.
Finally reconnect the shoeld to your tv. You will have choices resolution...
Hello.
I do not understand what you are talking about. Could you be clear? I have that same problem

I'm 99% certain the problem lies with your HDMI cable. Get a HDMI 2.0 or higher cable. A 1.4b cable by design doesn't support higher resolutions with a high refresh rate. It could do 4k but at 30hz only. 2.0 will support 4k , 2.0a will support 4k with HDR.
