Opening a terminal and typing xrandr yields: Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 345mm x 194mm 1920x1080 60.02*+ 48.03 1400x1050 59.98 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1368x768 60.00 1280x720 60.00 1024x768 60.00 1024x576 60.00 960x540 60.00 800x600 60.32 56.25 864x486 60.00 640x480 59.94 720x405 60.00 640x360 60.00 HDMI1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) Issuing xrandr -r 48 and the screen is steady and not blanking.
