Do you get any 4K modes listed when you run > 'xrandr' ? The problem is, I'd like 4k output but it seems I'm not getting it even though the card and monitor are both capable of it. Problem also is my lack of expertise in this area. xrandr output: Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384 DisplayPort-0 disconnected primary (normal left inverted right x axis y axis) DisplayPort-1 disconnected (normal left inverted right x axis y axis) DisplayPort-2 disconnected (normal left inverted right x axis y axis) HDMI-A-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1872mm x 1053mm 1920x1080 60.00* 1680x1050 59.88 1600x900 60.00 1280x1024 75.02 60.02 1440x900 59.90 1280x800 59.91 1152x864 75.00 1280x720 60.00 1024x768 75.03 70.07 60.00 832x624 74.55 800x600 72.19 75.00 60.32 640x480 75.00 72.81 66.67 59.94 720x400 70.08 DVI-D-0 disconnected (normal left inverted right x axis y axis) $ > I've been running 4K@60FPS on an external display for a long time on my > Intel laptops.

Would that work at 30 fps given that Xorg.0.log shows the following: [ 3474.097] (II) AMDGPU(0): Printing DDC gathered Modelines: [ 3474.098] (II) AMDGPU(0): Modeline "3840x2160"x0.0 297.00 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync (67.5 kHz eP) [ 3474.211] (II) AMDGPU(0): Printing DDC gathered Modelines: [ 3474.211] (II) AMDGPU(0): Modeline "3840x2160"x0.0 297.00 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync (67.5 kHz eP) ie, 4k @67.5kHz card output if I'm understanding correctly. thanks, -- J.
