I've done a little more research based on what you (?) told me about WDDM, and found out that (in theory at least) it should be possible to make the WDDM 1.2 driver work on Windows 10. dxdiag recognizes it as a 1.2 driver so I'm puzzled as to why it's being awkward.
This is literally the only way in which Windows 10 hasn't worked on here. Most of everything is great, and even the display works OK except for the odd UWP app (like Edge and Feedback Hub) whose interfaces completely mangle themselves up.
So I'm going to assume that there's a way to make it work. Logically, there should be - I just need to work out/find out what I need to do.

I have been checking the specifications of your tablet device and I have confirmed that the graphics controller included on this processor is part of Smartphone or tablet device.
I regret to inform you that any graphics driver is only available through your device manufacturer.
This is because Intel provides just the hardware to your tablet maker and according to their system designs;
they can release drivers for their devices.
Only your tablet manufacturer can tell you how to change driver settings.
