Ok, we can answer the question#2

But, what about #1 and #3


#47

The below code can answer the question

Hi, terry & kenny.
I was on vacation.

I’ll test it…


#53

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


#54

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?


#55

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.


#56

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.



#57

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



#58

Thank you for your feedback on the test.
could you tell me which resolution is on your monitor? @TomasFilip @davemf


#59

this resolution of 2560x1080 is not add yet, that will be add while the method I set is correct. and it looks like not work a right way. :sweat:

you can also have a try, flow this pdf:

You can refer to my changes:


#60

I tested all resolution on my displays 1280800 and 1360768.


#61

Hello Kenny,

resolutions what you see is 576p, the any of the 720p, 480p, 1080p works,
none of the others (what aren’t xxxp ) not working. What I can try is get a settings on second monitors (see strange pattern), when I’m probably can run the info about resolutions directly from monitors, maybe will give me a feedback about what is really set

The one monitors supports resolutions up-to 1920x1080 (23"5, HDMI/DVI/VGA), second 19" supports up-to 1280x1024 (DVI/VGA)

update: today I’m not able anymore used second monitor, looks that anytime when I’m connected them, is change res to 1080p, what is too high for them, so I cannot repoduced. I’m try Sony TV and that TV showes always correct resolutions, what was selected, but screen was never good. When I’m see screen it’s getting on my mind something what happend to me on kind of ARM device like last year…

I have right resolutions, but framebuffer is writing instead 32bits only 24bits. What causing very similar pictures. So pictures needs to be adjust acordingly to support RGBA instead RGB mode… Can be somehow that, for res. like 1024x768 incorrect depth of framebuffer is used?


#62

I’m testing Nougat rom (it’s crashing all the time) on Acer AL1717 , it’s 4:3 and max resolution 1280x1024. None of 4:3 resolutions working, I got same result as davems on screenshot DSC_9673.JPG, only blurry lines…
