Armbian version 22.05.3 Focal
Nanopi M4V2
There seem to be only default modes available with the nanopiM4V2. Manual adding a resolution does not work (it is added, but has no effect when selected)

The monitor is a Philips 498P (5120 x 1440). On my Pine64 with Armbian (22.05.3 Jammy) it does support additional resolutions up to 4K. I would like the 2560 x 1440 resolution to work. It looks like the nanopi is not able to read the edid data from the monitor. I have also mentioned this to NicoD and he did confirm this finding.

I have read that in the past this or a similar problem existed which was solved by removing the edid reading from u-boot. I have unsuccessfully tried that by building a new u-boot.
Does anyone have a solution?
