Did some googling. Seems like this isn’t just a problem with Surface Book? Threads on answers.microsoft.com (like this one: https://answers.microsoft.com/en-us/surface/forum/surfbook-surfperf/laggy-low-fps-performance-for-windows-10-ui-on/284760ee-3b16-4ece-9064-4b1428b5c4f7) have people with other models also complaining.
I don’t use any UWP apps. And I don’t have this issue when I plug an external monitor into my SB. This is my second SB, and I’ve never had this issue AFAICT. Lots of other issues that were gradually resolved over time (Standby etc. not working, blue screens etc.) but not this one.

What your suggesting below might work for a desktop – it doesn’t work for a laptop that isn’t always connected to an external monitor.

The way I resolve, is to only ever bootup/login to windows 10 with your external monitors plugged in. Then you can plug, unplug all you wish, as long as that first login is with the screens in But if you first login to the surface with no screens connected, then go and connect, it is crazy DPI problems. I have to then log off or reboot to make it look better. I have 3 Dell U2414H screens daisy chained into the mini display port - no dock needed.

It’s just raw rendering data pumped out over displayPort – and surely driver only cares about how many horizontal vs. vertical pixels to render. If anything this would be a Microsoft OS problem surely? FWIW, I haven’t experienced anything like David (I’ve got two different 4K monitors at home – 32” and 24”, plus 1080i monitors, and a whole bunch of different projectors, TV screens and monitors at work) – this is the first I’ve ever heard of this issue.

First impressions, screen is really bright. The Alcantara cover is very different to what I thought it would be (less material-like than I thought). Much lighter and smaller when closed to my original Surface Book (mind you this is the fastest Surface Book you can buy). Curves are really nice on the hands and must less sharp than its Surface Book cousin. I found my Surface Book lacking as dev-box (as I find with a lot of laptops), and UI performance really sucked if you connected an external monitor that wasn’t the same DPI – I suspect this thing would suffer from the same thing.
