Hi all, I have an HP Elitedesk 800 G5 SFF (9th gen Intel) at work. I have three monitors, two on DP and one on VGA. I want to add a 4th monitor, but I've run out of ports, so I figured I would add this old AMD Firepro v3900 GPU I have to give me an extra display port.
The GPU works just fine on our older HP desktops, but the second I plug it into the new machine, I get three long beeps and three short when I hit the power button.
I tried both PCIe slots, no joy.
All I want is an extra display port... help?
