Ye old projector resolution problem

[mash3d]

So I'm trying to get a B9 1.1 up and running using an Asus laptop with Windows 10.
I've gone into the display settings, advanced settings and set the second screen, the projector, to 1024 X 768.
No scaling or any other settings
The B9 Projector management software is seeing it as 1280 X 960. Which of course won't work.

Does anyone know of a way to fix this without using luck and duct tape?
Thanks,
Michael
