Yes, but from what I saw in the instructions for installing Windows 11 on the Raspberry Pi 4, you can actually switch screen resolutions in the UEFI BIOS there but this menu option is not present in the Pi 5 BIOS. I was wondering if there was a secret way which just hadn't been added to the BIOS.I don't think it's possible, because it's a hard limitation of Microsoft's basic display driver, which would seem to use EFI faciliites for screen access.
And I don't think you'll like it anyway, because that driver is also a fully CPU driven implementation without any type of acceleration, not 2d, not 3d, no video etc. much like an extended VGA: it's really no fun.
Without a device native Windows diplay driver from the SoC vendor, Windows on ARM just cannot fly and I wouldn't bet on RockChip ever doing one and they'd probably want ARM to do most of the work for Mali. And the open source guys sweating to extend Microsoft's overreach into the Raspberry PI universe? Not very likely, either.
Thanks, yes, I am using RDP to connect already, the performance is pretty good and it is entirely workable. Of course I always need a second PC for this set up.What might be worth trying is to see if using RDP actually improves the performance, because there is a bit of a chance that RDP might actually pass higher leven primitives over the wire to be rendered at the client side.
But I am not complaining. This is a great inexpensive test rig for my software development and it is amazing that people got it to work at all. I am only constantly looking for improvements...
