I have a trifire of 290 and 3 Asus VG 248QE 144Hz
I plug the hub in my display port and no DP signal detected on my screen. I plug a DP to DVI in the hub and it works.
To have my 3 screen work, I have 2 DVI and one DP to DVI. I tried the DP from my screen to another video card and the screen works.
I tried 5 different cable and it is always the same result. When I plug a DP in my card directly it doesn’t work but with a DP to DVI it works.
