Unable to receive display from USB C or Display Ports on Vector Quad
post by vms on Nov 9, 2023
Hi,
I have tried connecting both USB C and Display Ports (there seem to be 4 per GPU and so total of 16 in my case). I have also tried swapping the SW switch for VGA. The display does not connect.

There is not a USB-C on these GPUs, so you are likely just connecting to motherboard USB-C used for normal USB data.
Do you see the BIOS on the screen while it boots? Or does it only go blank after the OS gets started?
General Issues:
- Cable Issues (try a known working cable)
- Wrong setting/interface on Monitor
- Monitor may not be supported (try a different monitor)
- Cable converters and extenders add extra points of failure.
- Try a different GPU
Recently there have been issues with BAR memory where the OS cannot allocate.
So on Desktops enabling the ‘SR-IOV’ and booting with a kernel parameter of ‘pci=realloc=off’ can affect GPUs or other devices.
Power down, remove power and make sure the VGA switch is off, and IPMI/BMC switches are on (not half way on/off). The manual does state to remove the power plug. ( Documentation Link )
Then power up.
And resetting the CMOS, there is a button at the top of the back I/O ports, above the WIFI connectors to clear the CMOS.
This is a WRX80E from the picture.
