16.04kubuntumultiple-monitors
Using Kubuntu 16.04, I haven't found a way to get to the "Display and Monitor" settings without first going to "System Settings" and then click the display and monitor icon. This annoys be, because I would rather like to have an icon or tray setting (like the old krandrtray) to easily switch monitor configurations.
Is there a way to get to the "Display and Monitor" dialog directly — via the command line, or some widget?
Try installing arandr ,in your system as it gives you gui , which is easy to mange
.
In the outputs tab you can easily turnoff your laptop's display (LVDS) and keep your monitor's one (VGA or in your scenario it might be HDMI1) as your primary display and save the layout. Add the following layout script into your startup menu, so when next time you login to your desktop it works without any extra inconvenience.
In case anyone else runs into this, this is what I did (though I imagine there must be a better way): I got a spare monitor and connected it to the computer (after turning it off), along with the original monitor. (Fortunately my video card had multiple plugs.) On rebooting, I used nvidia-settings to move the new monitor's position to below the other one. That gave enough room for all (or at least enough) of the System Settings window to be visible, so I could get to the Scale Display bit and reset it back to 1. Then I shutdown the computer and removed the extra monitor. On restart, the GUI was back to normal size and I could see all of the System Settings window.

I think the what you are looking for is the command
kcmshell5 kcm_kscreenOn a sidenote, to find out which modules you can start with kcmshell5, use
kcmshell5 --listPersonally, I think the easiest way is, to activate krunner (Alt+Space or Alt+F2), enter Display and what you are looking for should be one of the suggestions (the first one on my system).
