failed to set mode: Invalid argument on ls1028

Hi: I am testing OpenGL according to the software manual(OPEN-LINUX-IND-UM-1-10.pdf), but there will be errors. Can you give some suggestions?

I cant' reproduce this issue on ls1028ardb board with DP interface + 1080x1920 display (DELL).

I just confirmed with the testing team.

kmscube can work fine on DELL display with 1920*1080 resolution.

On LS1028ARDB, 'kmscube' can work on certain display monitor while can't work on certain other display monitor.

Hi：

Thank you for your reply. I just confirmed that this is a 4K monitor.I found the information in the manual：

For eDP interface, 4K resolution is not supported due to firmware limitation.So how do I test GPU on 4K monitor.
