21:9 display (lg ultrawide)
#1
Can rock64 / rockchip display 2560x1080 resolutions?
I have tested feeding a few different modelines to xrandr with a LG 25UM58 monitor without success...
I have attempted 10 different lines generated with both cvt and gtf, 5 with each, varying the refresh rate (20, 30, 40, 50, 60).

My base image is ayufan bionic minimal 0.6.31

Here is part of a dmesg output:

On a different computer (Mac OS) I had to tweak the resolutions config in order to make the resolution work, using a software called switchresX that has a functionality of exporting the EDID, so I think I can copy useful information from there if needed, such as pixel clock, front porch, sync width, back porch, blanking... or the hex of that working setup.

I wonder where is the proper place to file an issue... https://github.com/rockchip-linux/kernel/issues maybe?

Anyways, here is more info:

Have anyone succeeded in setting a 2560x1080 resolution using custom edid binaries? Not sure if that would work, but one idea would be to use  https://wiki.archlinux.org/index.php/Ker...de_setting and https://github.com/akatrevorjay/edid-generator does the mali/rockchip support this?
