Hello Everyone,
I have a Dell XPS 9350 laptop that I use a USB-C adapter to connect to an external display (Dell U2717D) with my setup. The monitor is detected and everything works correctly, my issue is as follows:
Problem:
When connecting the USB-C cable to my external Dell monitor, the resolution on my laptop’s screen changes. Everything becomes super small in terms of fonts and resolution and I am no longer able to use the laptop screen as a secondary display. I have the scaling set to 200% on my laptop’s internal display, and 100% set on the External Dell Monitor.
When I unplug the USB-C, everything resets correctly on my laptop screen and I am able to use it without any issues.
I am attaching my system information below:

If anyone could offer any assistance on how to manage an external display + internal laptop display correctly, it would be greatly appreciated.
Thanks,
