Wondering if anyone has come across this problem before.
I have a brand-new X1 Extreme (bought in March) and a 4-year-old Dell 27" 4K monitor. In the last few days, I've had really low fps when using the monitor, while the built-in display works fine. This is all at the Windows desktop, ie not games or anything that should be super-demanding.
Some more details:
The monitor was mostly working fine before this. I say mostly, because it's had problems for years relating to waking up from sleep; I'll often have to unplug it from the wall and plug it back in again for Windows to see it. But once it was running, it was okay.
Solved! Go to Solution.

If I go into Settings -> System -> Display and change the layout to either "extend displays" or "duplicate displays" then the performance is fine. It's only if I set it to use only the monitor that it goes wack.
Edit: Also tried setting the monitor resolution to 1080p (**bleep**, it's ugly) to check that it wasn't a connection bandwidth issue. The problem persists.
