HDMI Stopped working after BIOS Update

EliteDesk 800 L1W21AV
Microsoft Windows 10 (64-bit)

After updating the BIOS to the latest June version, the HDMI output just stopped working.

 

I tried connecting the cable to the display via DisplayPort to HDMI adapter, and it works, so that problem is not in my cable and not in my display.

 

Trying to connect the HDMI to the display and using Picture in Picture I can see that the display doesn't detect any HDMI displays. 

 

Resetting the CMOS doesn't help.

 

Any ideas?
