I’m currently going from 2 screens (DVI to DVI) to 4 screens and brought a CSV-5200 to take advantage of the display port I have. Probably me but I can not get the CSV-5200 working with my setup. When I plug directly from a monitor to the display port it works fine. If I use the CSV-5200 my monitor says “input not supported” and I get the display but squashed (1/5th of the screen is not displaying), plug the monitor in directly again and works fine. This happens on both screens plugged into the display port. I have used the scan button.
The card and catalyst drivers sees the display port being used and both monitors. Even shows the correct resolution and refresh rate, but still not working.
I have tried:
just using the display port with just the 2 screens.
one monitor and one port in the mst hub
classic reboot (with just 1 screen and then 2 screens…)
one arm in the air
two arms in the air
Any ideas what else I could do? I would like to use 4 screens but it isn’t even working with just 2 screens?
