Recompile to add 2560x1440p resolution?

It seems that the resolution 2560x1440p is currently not supported to by any available images for VIM2 yet. Could you please point to some resource/quick guide on how to do it on my own? Any OS is ok for me, but i suppose Linux it is easier. I already tempered around with to set the mode when recompiling the image, but it did not help.

@Khadas staff, any timeline for new resolutions for VIM2? Could you please also confirm that 4k resolution is supported out of the box (with the official android and linux images)

Thanks a lot in advance - A.
