HDMI Resolutions testing

Will there be a solution?

I’m too waiting for a 800x480 output in Nougat and mmallow…

Any ETA for a solution?

Best

Hello. Any news? I’m waiting for 1024x600 too.

We are applying the documentation from Amlogic, will share here and keep researching on this.

And Where is it?
How long to wait custom resolutions?

Hi, terry & kenny.
I was on vacation.

I’ll test it…

I have a Philips 298X4QJAB 29 X-Line Monitor
Resolution 2560x1080
On give me the modified file with that resolution i can test it
I am willing to test ubuntu

Hi Kenny,

when I’m saw pop-up that thread, I’m quickly make some test with ROM

The “native” HDMI resolutions like 1080p, 720p (finally :slight_smile: ) either 480p is working. So I’m see progress here, because 720p, 480p not well working either previous advices was applied.

unfortunatelly non of the 640x480, 800x480, 800x600, 1024x600 is working for me. Try either native HDMI cable or HDMI-DVI cable. Others resolutions isn’t avalaible in my monitors, it’s system finally use EDID info?

I can not test HDMI resolution, because Nougat work is very bad.

The Nougat constantly hangs and errors out (see video http://www.mediafire.com/file/fx8m6u6umhd4dy4/MOV_9670.mp4).
List of HDMI resolution does not has new values.

I was tested it.
New resolutions can select with keyboard only, mouse can not select it.
New resolutions does not work on all my monitors.


I can confim davemf findings, my screen looks quite similar like on the screenshot, one monitor say, 'input not supported = acer 24", Fujitsu Siemnes shows similar paterns we see" when I would like try differents settings than 1080p, 720p, 576p, 480p like 800x600, 1024*768 etc
