Hi all,
Today I was try to adding secondary screen (hdmi) and couldnt figure out why hdmi was visible in terminal but not on "Preferences>Monitor Settings". However I figured out and in case if you going to use secondary screen on TB use following steps;
# list all the available output resolution
$ xrandr
most probably you will have DSI-1 as primary and HDMI-1 is disconnected.
# activate hdmi over dsi
$ xrandr --output HDMI-1 --auto --right-of DSI-1 (make sure the device name is the same as listed in "xrandr" command)
# Change resolution of HDMI
$ xrandr --output HDMI-1 --mode 1920x1080
After this commands, the same settings will be visible on "Preferences>Monitor Settings"
Some other useful commands can be helpful on wiki but they havent mentioned for secondary screen.
Hope this helps
