I’ve had a CSV-5300H for a couple years now, but I rarely use it because I didn’t realize until after I ordered it that I needed DP v1.2 with HBR2 & MST. I now have a laptop with appropriate support (HP ZBook 15u G4) on the integrated graphics adapter, and I can’t seem to get it to work. I have a variety of Samsung monitors at my disposal with DVI-D in, and my laptop detects the hub and the displays, but I can never seem to get an image to appear. The monitors make it seem like they have something to display: one model has a solid LED like it has a connection on the DVI-D link, but doesn’t even kick on the backlight, and the other model switches between it’s VGA and DVI-D inputs like it doesn’t have signal, but it blacks out when it switches to the DVI-D link. Using an Extron DP v1.1 active DP->HDMI adapter, both models show a desktop. I have a sinking suspicion the CSV-5300H has had some sort of failure, but I’d like to try a firmware update if one is available, if nothing else. Thanks!
