I just buy a 4k screen. Now my most usual setup is 27" 4k left, full HD (laptop)
center and full hd right.
The new screen should be used only for video editing, not always.
But my usual setup is completely changed by the new screen: even the cursor size is
changed (much bigger).
I use the "supplementary action" from kde to open my main applications on the
desktop I want (I have 10 of them), but fail to find a way to have all my applications
open in the "main" screen (as setup in the kde
panel), because the x coordinate changes
NB: I still use 15.1, for some reason I can't make my system works as expected in
maybe a workaround:
i have a old software who is not able to scale to 4k screens.
i have made a small batch file to switch one of my 3 4k screens down
to a lower resolution only when i start this software.
so maybe you could start kde with all your screens in a lower resolution
(then your cursor should be ok)
and switch only one screen to a higher when you use your software.
as example (parts) of my script
xrandr --output DisplayPort-2 --mode 1920x1080
start your application
laeuft=$(ps fax |grep "your-application! |grep -v /bin/bash |grep -v grep)
if [ "$laeuft" == '' ]
xrandr --output DisplayPort-2 --mode 3840x2160
of course you have to change "DisplayPort-2" to your screen-connection-port
