I tried downgrading to FY0015.BIO and FY0021.BIO but that didn't fix the resolution problem.
So I upgraded back to FY0025.BIO and tried running in UEFI mode which was the default configuration for the original BIOS and suddenly I can see 1080p resolution again.
The thing is I don't want to run UEFI mode. I am not particularly interested in having a rootkit with reverse ssh installed directly on my computer so that the NSA can monitor me if they feel like it.
Is there any way to get 1080p resolution while using the Legacy BIOS? There shouldn't be a hardware limitation for the video card just because of the choice of BIOS. I have other devices that can run 1080p perfectly well with a so called legacy BIOS. It's not a limitation of any operating system that I know of so why has intel decided to cripple 1080p in this way?
I'm sure there is no ulterior motive on behalf of Microsoft /NSA to force people to use UEFI on these devices so perhaps there is a simple BIOS flag that I am missing?
Bh1, it looks like there were some changes on the BIOS settings and the VBIOS, therefore this could be a hardware issue.
Since the resolution appears after enabling UEFI, this is for sure a BIOS situation. My recommendation will be to replace the NUC and if the replacement works OK using the original BIOS, please do not upgrade it.
