2560*1440 HDMI resolution on Android: how to?

Hi all,

I have a great 2560*1440 panel and would like to get the most of it with the Khadas VIM2 (MAX) on Android (7.1.2, current version).

Currently, it only gets up to 1080p@60 Hz and there is no Android option to get higher than this (only lower). It’s supposed to support up to 4K though, so is there any way?


I’m sorry to reply for you so late. The VIM2 don’t support for resolution 2560*1440 output.

Thanks. Is this a video controller limitation, or a software one?

It need to modify many clocks and register of CPU. You can refer to HDMI_CLOCK.pdf
and try to add support for it, Thanks.

Hello! Can you tell if there is a way to run at 2560x1080 (ultrawide)? I am not a Linux expert, just an enthusiast, I do not understand deep kernet patch applications and so on. I have seen in an Armbian forum that in fbdev mode in the latest kernels it is possible to enable newer resolutions, can you tell if this applies to khadas? What do I need to do to run Khadas in fbdev on Armbian with kernel 4.17 or later?
