After updating BIOS from 025 to 026 i got no video at boot with dual monitors attached.
Each separate monitor was ok to boot with, and in Windows I could connect the second monitor and everything was fine but the NUC wouldnt start with both monitors attached from the beginning.
I installed 025 - no difference
Uninstalled graphic drivers - dual monitors appear on boot with MS basic display adapter.
Installed latest drivers 10.18.10.3621 - still wouldnt work.
Uninstalled graphic drivers, installed drivers 10.18.10.3496. No difference
Uninstalled graphic drivers, installed drivers 10.18.10.3412. No difference
Installed latest drivers 10.18.10.3621 again, no difference.
Then i updated to 026, and suddenly it WORKS!!!
This is really strange, because I was already on the latest graphoc drivers when I updated to 026 in the first place.
An explanation would be nice!

I managed to reproduce the error, and it occures when I try to access the BIOS via F2 with dual monitors attached.
The screen goes black and I cant start the NUC if I dont disconnect one of the monitors.
After that I see an error message, "BIOS has detected unsuccessful POST attempt(s). Possible causes include recent changes to BIOS Performance Options or recent hardware change. Press 'Y' to enter Setup or 'N' to cancel and attempt to boot with previous setting.".
I press 'N' and everything works fine, and I can attach my second monitor and boot with them just fine.
Just have to remember to disconnect one of the monitors when I need to access BIOS settings then. This wastnt any issue in previous versions though...
