hdmi output to 720p TV [solved][howto]

Recommended Posts

Hi

Now that I've got my Vega dock setup I'm working on turning it into a mediacentre.

I've searched the forum and see people outputing by hdmi to 1080p TV's, but not seen anyone mention 720p. When connecting I get a message on the TV saying "out of range". Is there anyway to change the kernel to output 720p or is this a hardware only thing? Am I scuppered by my cheap TV?

Thanks,

Steven

ps. see post 4 for solution. http://android.modaco.com/index.php?s=&amp...t&p=1730003

What make and model TV is it? It works fine on my samsung which won't do 1080p and worked fine on a cheap LG when I was on holiday.

Not sure if there is anything useful for you in this thread but might be worth a quick read.

modaco enable vega hdmi thread

Hi,

Its a cheap Techmagic, hmm I can't remember if thats the name or not. I'll have to check name and type when I get back home.

edit: Actually its a Techwood 19884HDDVD

I've now tried it on a 1080p tv and it works, so I know output and cable are fine for that.

I've read that thread thanks, but didn't find anything specific to using 720p tvs.

edit: Reading the manual on TV, it has partial support for 1080p, accepting 50Hz and 60Hz, but not 24, 25 or 30Hz.

Thanks.

Solved the problem by finding a useful web page from Nvidia.

http://developer.nvidia.com/tegra/forum/se...roid-resolution

In a terminal on device or adb shell

setprop persist.tegra.dpy5.mode.width 1280

setprop persist.tegra.dpy5.mode.height 720

Then reboot your device.

You can experiment with various sizes to get the best output for your TV. For me 720 looks quite rough in the way the picture is scaled, setting 1024 by 600 displays fine with black borders.

Hope this helps others.

Do you happen to know what the original values where, just for reference or was there some sort of auto setting enabled

On my tablet it says:

getprop persist.tegra.dpy5.mode.width says 1920

getprop persist.tegra.dpy5.mode.height says 1080

You can always see the original values in the /default.prop file. They are 1920 x 1080.

Thanks, by any chance have you noticed wifi not being able to connect when at 1024 x 600?

It connects fine when changed to 1280 x 720 but didn't connect when at 1024 x 600 when I tried last night.

(Running VegaComb btw)

Ah yeah I did have a problem with wifi, thought it was just a hicup, I'll have to try again when I get home tonight.

Me too.

Has anyone noticed any performance improvements when lowering the output resolution?

I noticed displaying to my 1080p TV sometimes caused glitches and freezes, I wouldn't mind outputting at 720 if it meant it was smoother.

Look at post#4 in this thread: http://android.modaco.com/content/advent-v...ocking-station/

Would disabling the Vega screen and enabling HDMI only improve performance?

Yes it seems my wifi is broken ;) I wasn't sure if it was related to these changes but if your having some problems it could be.

Sorry.

No problem scarrie, just seems strange that wifi works fine when the output res is changed to one value and not the other.

I'll have a fiddle around later, only changed it to see if the image would be better, but would also like to see if I can slightly increase the res to in essence hide the bottom status bar on the vega.

I managed to fix wifi simply by deleting /data/misc/wifi_suplicant.conf and re-entering the details in the wifi settings.

Yes thats the way I id it. I think you need root so need to type "su" into terminal emulator first.

I just cannot get this to run full screen on my TV. Black borders on the right and bottom. Is there meant to be a confirmation in the emulator

don't forget to reboot after changing the settings.

You can also try getprop to see what the current settings are.

I think it must be my TV. Changing the numbers does not change it at all, it remains the same size.

It ran full screen with the stock ROM but very pixelated.

Very annoying as I bought the Vega mainly to output NFL gamepass to my Flatscreen :-(
