Hi,
I can confirm the problem with version 0322 an 0323. It was exactly the same for me, as I changed the standard display adapter from Auto to Intel Integrated, no video would work any more. All ports, HDMI, Displayport and DVI have no signal but send DPMS-Standby to any attached display. This is not only true for the UEFI configuration and boot screens but for the booted OS as well.
Will Intels firmware engineers read this or will the forum moderators forward the most common problems to them? This one seems to be a no-brainer, as it is easily reproduced and hopefully fixed.
Hans, thank you for your fix blindly loading the defaults via F2 ... F9 Return, F10 Return. This worked for me on the fist attempt. My build is inspired by c't magazine, as well.
