I connect an external screen (Toshiba TV) via HDMI but Linux doesn't recognize it.What can I do? Can it be a hardware problem?xrandr:Screen 0: minimum 8 x 8, current 1600 x 900, maximum 32767 x 32767eDP1 connected primary 1600x900+0+0 (normal left inverted right x axis y axis) 309mm x 174mm   1600x900      60.01*+   1440x900      59.89     1368x768      60.00     1360x768      59.80    59.96     1152x864      60.00     1280x720      60.00     1024x768      60.00     1024x576      60.00     960x540       60.00     800x600       60.32    56.25     864x486       60.00     800x450       60.00     640x480       59.94     720x405       60.00     640x360       60.00  DP1 disconnected (normal left inverted right x axis y axis)HDMI1 disconnected (normal left inverted right x axis y axis)HDMI2 disconnected (normal left inverted right x axis y axis)VIRTUAL1 disconnected (normal left inverted right x axis y axis)The TV supports 1360x768, so I tried adding the mode via xrandr --addmode HDMI1 1360x768.Activating the mode with xrandr --output HDMI1 --mode 1360x768 --right-of eDP1 fails:xrandr: Configure crtc 1 failedsudo get-edid:This is read-edid version 3.0.2.
