I just set up a second Unraid server. I am running it headless. Need to access the Bios though to enable IOMMU groups (V-T setting?).

 

Unfortunately, I have no clue how to attach an external screen to my Unraid server, which I'd assume I need to access the bios (cannot do headless)?

 

I connected an HDMI cable to my TV, but don't get any screen. Tried both the iGPU as well as the Nvidia-GPU connection. Not sure, which one is the right one? Any practical advice how to connect my TV via HDMI to my Unraid server.

 

I am sure I am missing something *very* basic here

Have you tried with the TV plugged in but not the Unraid flash drive.   That would stop you getting past the BIOS level.   If that does not work then the issue is compatibility with the HDMI on the TV and your motherboard.

Thanks for your help. Unfortunately, I still cannot get it to output any signal to the screen. I tried with and witout the Unraid flash disk. But without luck 😞

 

To avoid that the issue is with my TV, I instead used a Dell monitor, which I'd assume should be safe and works with several other devices. But yet again, no luck. No matter what I do, there is no output to the monitor.

 

Any other ideas? I'd assume I may miss something very trivial?

Maybe you can try removing the GPU and connecting direct to mobo, see if that gets you to the BIOS...

 

This is all before unraid even starts loading, so not much it can do to help.

Did you ever figure this out? I'm in the same boat now
