Screen Orientation during install

[Bound_By_Physics]

I have a standards Windows ISO that I have customised for use on a tablet, the only issue, is that when it installs, it is in portrait mode rather than landscape. My question is, is there any setting that I can adjust that would switch it to landscape when running the installation?

There's no Windows feature for changing the default screen orientation during WinPE. Setup takes your BIOS's display layout and uses it. Not until your Windows restarts in specialize mode, can it install the tablet's hardware sensors so it knows how to flip orientations.

Some users have suggested using a 3rd-party monitor tool which can rotate displays. They probably don't work in WinPE, but it may be possible to script running it from autounattend.xml in the specialize pass.
