When you are testing the DisplayPort/HDMI on a laptop, and the Display option in Settings Manager is not allowing you to select the external monitor, try the following:

After plugging the laptop into the external monitor, open terminal and enter <code>xrandr<-code>. This will give a display like this:

<code>
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
1280x800 60.0*+
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
DP3 disconnected (normal left inverted right x axis y axis)
</code>

Depending on your system, LVDS will be either 0 or 1, and DisplayPort (DP) and HDMI could also be 0 or 1. If your system has multiple DisplayPort or HDMI options, the computer will note which one has the external monitor plugged in; that's the number you want. After than, copy/paste the following code into terminal:

<code>
#!/bin/bash
monitor_choice=$(zenity --list --radiolist --column ' ' --column 'Monitor Setting' True "Main Monitor Left" \
False "Main Monitor Right" \
False "Second Monitor Off")
echo $monitor_choice
if <nowiki>[[ $monitor_choice =~ "Left" ]]</nowiki>; then
xrandr --output DP-0 --auto --left-of LVDS-0 --rotate normal
xrandr --output DP-0 --auto --left-of LVDS-0 --rotate normal
elif <nowiki>[[ $monitor_choice =~ "Right" ]]</nowiki>; then
xrandr --output DP-0 --auto --right-of LVDS-0 --rotate normal
xrandr --output DP-0 --auto --right-of LVDS-0 --rotate normal
elif <nowiki>[[ $monitor_choice =~ "Off" ]]</nowiki>; then
xrandr --output DP-0 --off
xrandr --output DP-0 --off
fi
</code>

If you have an HDMI port, change DP to HDMI. Change the numbers next to DP and LVDS to the ones used with your system.
Hit enter, and an option will pop up, select the left monitor. Hit enter again. The external screen should now show the laptop screen.
