Lambda Workstation no display from GPU

We recently lost the network connectivity to the workstation with 4 RTX 2080 Ti. I tried to recycle the power, but the network activities stopped a couple of minutes after the workstation rebooted.

I tried to hook up a monitor to the GPUs but I am not getting display from any of the four GPUs, and there is no onboard VGA port.

How can I get the display to work in order to start troubleshooting the issue?

Thanks,

Hey not sure if you figured this out, but I was running into a somewhat similar issue where the BIOS would show but then it would seemingly switch over to VGA (and I also had no port). I ended up being able to flip a switch on the motherboard to disable the onboard VGA

Once I flipped that, the display stayed on the HDMI
