Tonights( 20191002) nightly build will have support for 1366x768p60hz on the amlogic builds for the s912/s905 variants.
To use create a /storage/.kodi/userdata/disp_add file and add 1366x768p60hz to it.

Hi @cdu13a,
I have just tested this on the latest nightly (20191019) and it works like a charm.
Does this mean that the resolution support will get into the next stable release? That would be fantastic.
Many thanks
Mike
@myso glad that worked for you.
Yes the extra resolution support will be in the next stable release once that happens. I can’t say when that will be since there is still a few things that need to be fixed up before the next stable release happens.
Can you please reffer commit(s) for that? Out of curiousity… Is it just this? (refer.)
Wondering, if modeline "1366x768p60hz" within bootargs did the same job without any modification or is there somthing under hood…
I tried to add 2560x1440p60Hz to here on my VIM3 Pro: /storage/.kodi/userdata/disp_add
but it freezed my monitor.
Then I tried to add 2560x1440p50Hz and got this:
Is there any chance to use this resolution?
@cdu13a Thanks, you made my day!
I was able to add 1280x1024 for S905x:
Also thank you @boot2k3 for pointing me out.
Is that disp_add documented somewhere?
LE has disp_cap, does it work here? What is the difference?
@bam disp_add does just what it says. It adds any modes listed in it to kodi’s known list of video modes. disp_cap overwrites kodi’s list of known video modes.
Use of disp_add is preffered over the use of disp_cap, since it doesn’t block use of modes advertised by the display. Which tends to drastically cut down the support questions that seem to oddly pop up 4 months after a user sets disp_cap, and has forgotten they set it and are now trying to figure out why they can’t set X resolution on their shinny new display they just bought.

Thank you!
@cdu13a thanks for the explanation.
Then I still can’t understand why in Kodi I don’t see 1280x1024 mode native for the display?
It seems advertised by the display:

Basically the same result as posted above by Pelican. But I remember that this trick used to work just couple of versions back and must have regressed somehow.
@cdu13a can you please have a look at this?
I think it stopped working around the time we had a major kernel change a few versions back.
Can you log in via ssh and run dispinfo and post it’s output here.
I unfortunately don’t have a display that can do that resolution, or a way of emulating it. But I may be able to sort something out. I’m however getting ready to move so I’m not sure how quickly I can do this.
Thanks. Let me know if you need more info.
Update: here’s a result of running get-edid -b 6 | parse-edid while this monitor is connected to PC.
This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
Only trying 6 as per your request.

Looks like i2c was successful. Have a good day.

EndSectionI just bought a new s905x3 based box to replace our aging s905x box so I can migrate to ng. On our old box 1366x768 output works fine. On this new one when I change to 1366x768 my TV says not support. Did something change with the new kernel to make this no longer work? Is there some way I could possibly troubleshoot this?
edit: my dispinfo http://ix.io/2QCa
Experiencing the same issue as @quickfast
Tyring to use 1366x768 resolution on the Panasonic TV, screen stays black.
Device: Orbsmart S97pro (S905x4)
Running Coreelec amlogic-ne 20
dispinfo here
Did this only work in earlier releases?
@quickfast @Orbsmartie I get something on Vertex when I limit display colour depth to 8bit.
But I am not sure if this is correct. With 12 or 10 bits I get only a black screen.

Hi @Portisch ,
thank you for the recommendation, tried it, unfortunately same result, screen stays black and then defaults back to 1280 * 720.
Any other idea, any kind of log i could provide?
Just use 1080p?
It’s even higher than 1366*768
Would love to, however the TV (Panasonic TX-32FSW504) only supports HD Ready (1366 x 768 Pixel). 
Your disp_cap tells something else
