I’m using a Dell XPS13 (3200x1800 resolution) with a UD-ULTCDL and 1920x1080 Samsung LCD. I use the monitor to mirror the screen.
When I connect the monitor to the XPS13 the icons and text etc look right i.e. adjust to 100% scaling, but if I then disconnect the monitor the scaling stays at 100% so everything is TINY on the XPS13. The correct scaling for the XPS13 is 250%. I have to reboot to make it usable.
I have the latest drivers for the UD-ULTCDL, XPS13 chipset. I don’t want to extend the monitor since this will be very confusing for my wife, who is technophobic and having trouble getting used to Windows 10, never mind using the screen differently!
Can you help?
