This is why I'm using interlaced: $ *xrandr* Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 DisplayPort-0 disconnected (normal left inverted right x axis y axis) HDMI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 16mm x 9mm 1920x*1080i* 60.00*+ 50.00 59.94 1920x1080 *24.00* 23.98 1280x*720* 60.00 50.00 59.94 1024x768 75.03 70.07 60.00 832x624 74.55 800x600 72.19 75.00 60.32 56.25 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 75.00 72.81 66.67 60.00 59.94 720x400 70.08 DVI-0 disconnected (normal left inverted right x axis y axis)
I think the driver should only support resolutions that are *progressive*, but also at least of *50Hz*.
