I gave it a try tonight, and unfortunately it appears to currently always attempt to use 1920x1080p60 as the mode regardless of the monitor. For example, on an old 720p monitor I had laying around: [ 225.732342] rockchip-drm display-subsystem: [drm] Update mode to 1920x1080p60, type: 11 for vp0, output 0x00000800 HDMI0 This results in a broken picture (all white with occasional glitches). Somebody else observed the same behaviour on a 1440p monitor. Thanks, Nicolas Frattaroli
