I bought the CSV-6400 with hopes of it driving six monitors off of my AMD Radeon XFX R9 290X.
I’m following guidance from:
The card has the following ports: 1x DisplayPort, 1x HDMI, 2x DVI.
Currently I have the first two monitors connected to the DVI ports on the card.
The MST hub is plugged into the DisplayPort on the card, and the remaining four monitors connected to the MST hub using 4 of each of these:
DisplayPort to HDMI adapter
which are each plugged into:
HDMI to DVI adapter
The monitors are connected using DVI cables.
When the PC boots, I see the windows splash screen on the first monitor (first DVI port on the card) and all four of the monitors connected to the MSI hub. Only the second monitor (second DVI port on the card) doesn’t show the Windows 10 splash screen (which is expected, as this is normal). Once Windows is fully booted only the first and second monitors (connected to the DVI ports directly on the card) will display anything, and the four monitors connected to the MSI hub are black. The AMD Radeon driver only detects two monitors and Eyefinity will only span between the two monitors.
Is there a driver I need to install to get the MSI hub to work? Should it appear in device manager? Can all four of the adapters between the MSI hub and the monitor cables be passive, or do at least some of them need to be active adapters? How do I query the MSI hub to see its firmware version?
Since I do see the four monitors that are connected to the MSI hub work for a couple of seconds when Windows is booting up (they display the Windows splash screen before going black). I’m thinking this must be a software issue. What steps can I do to troubleshoot? I’m running Windows 10 version 1803, and Radeon driver 18.12.1.
