Can't do fresh install of W10, no UI after booting into installer

The slightly longer version:

I've tried both the in-Windows path and a USB key with Windows 10, and both times I boot into the installer application, but there's just a black screen. The monitor is on, actively displaying black (no power-save mode), but there's nothing happening.

I've tried alternately unplugging the monitors I have on the iGPU and the 1080Ti, set the EFI to boot to the iGPU or the PCI-E video devices, but nothing works.

I'm out of ideas, and REALLY need this PC clean...

Hi there. Is there an OS on it now? If so, does it boot up and the monitor work? If so, does it have the latest driver?

Edit:

Is there a cursor with the black screen?

There was Windows 10 on it already, everything worked fine, just not in the installer.

I managed to solve it by installing an older GPU and running the installer, getting the latest GPU drivers in, then removing the olg GPU again. Hopefully the next Cumulative Update will add better hardware support in the installer.

Ok. Yes, it's usually the graphics driver that's not supporting that.

Rather tedious, but great work-around.
