NUC8i3BEK HDMI output "Out of Range", works during boot and with graphics driver uninstalled

Jump to solution

We have almost 2 dozen NUCs that we've set up in our workplace. Recently, I had one NUC8i3BEK whose HDMI stopped working. Tried many things (the 1.77.01 HDMI firmware update, rolling back drivers, etc.). I even wiped the machine and started from scratch, and the problem was still occurring. I replaced that machine and moved on.

 

We just got another 5 NUC8i3BEK NUCs, and the two I've set up have both had this same issue (HDMI works during boot and also with no drivers). More info at the bottom.

 

Has anyone had anything like this happen to them? What else can I try to get this fixed?

 

Thanks in advance for your help.

Here's the solution someone on Reddit helped me find:
Flashing the original 1.73 firmware and reinstalling drivers after using DDU seems to have worked (Link to firmware: https://downloadcenter.intel.com/download/29092/HDMI-Firmware-Update-Tool-for-NUC8i3BE-NUC8i5BE-NUC8... ).

I've also tried different cables and monitors with no change. I tried having two monitors of the same make and model, and would switch outputs (from USB-C to HDMI and vice-versa), and the HDMI would show "Out of Range" or no signal, and the USB-C would work like normal. Checked resolution and Hz, they were both correct.
