Here is the output of xrandr : ### Initial xrandr result, when no problem is present (except that the hdmi monitor refresh rate should be 144Hz but is detected at 120, maybe this is related) ### Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767 HDMI-0 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 531mm x 299mm 1920x1080 60.00 + 120.00* 119.88 100.00 59.94 50.00 23.98 1680x1050 59.95 1600x1200 60.00 1600x900 60.00 1440x900 74.98 59.89 1280x1024 75.02 60.02 1280x960 60.00 1280x720 59.94 50.00 1152x864 75.00 1024x768 75.03 70.07 60.00 800x600 75.00 72.19 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 59.93 DP-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 544mm x 303mm 1920x1080 60.00 + 143.98* 119.98 99.93 59.94 50.00 1680x1050 59.95 1600x1200 60.00 1440x900 74.98 59.89 1280x1024 75.02 60.02 1280x960 60.00 1280x720 59.94 50.00 1152x720 59.97 1024x768 75.03 60.00 800x600 75.00 60.32 720x576 50.00 720x480 59.94 640x480 75.00 59.94 59.93 DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) DP-4 disconnected (normal left inverted right x axis y axis) DP-5 disconnected (normal left inverted right x axis y axis) ### After incorrect waking-up : HDMI monitor is back to 60hz and mirror mode ### Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 HDMI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm 1920x1080 60.00*+ 120.00 119.88 100.00 59.94 50.00 23.98 1680x1050 59.95 1600x1200 60.00 1600x900 60.00 1440x900 74.98 59.89 1280x1024 75.02 60.02 1280x960 60.00 1280x720 59.94 50.00 1152x864 75.00 1024x768 75.03 70.07 60.00 800x600 75.00 72.19 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 59.93 DP-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 544mm x 303mm 1920x1080 60.00 + 143.98* 119.98 99.93 59.94 50.00 1680x1050 59.95 1600x1200 60.00 1440x900 74.98 59.89 1280x1024 75.02 60.02 1280x960 60.00 1280x720 59.94 50.00 1152x720 59.97 1024x768 75.03 60.00 800x600 75.00 60.32 720x576 50.00 720x480 59.94 640x480 75.00 59.94 59.93 DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) DP-4 disconnected (normal left inverted right x axis y axis) DP-5 disconnected (normal left inverted right x axis y axis)
