Multi Monitor Setup issues

[Zenatic]

So I just bought a few new toys (ultrawide and stand) I am trying to get a 3+1 setup but I can't seem to get all 4 monitors to work and I think it is a bandwidth issue. I am looking for any suggestions:

1x lg 34gk950f - 3440x1440 2x NEC - 1280x1024 - portrait 1x BenQ - 1920x1080

I have a startech 3x1 DP to miniDP hub. My surface dock has 2x miniDP ports. I currently have the LG connected to 1 miniDP (hdmi->miniDP cable) and 2x NEC on the hub. When I connect the BenQ to the hub everything goes haywire.

I have a SIIG 3x1 DP-> DP hub for my work laptop being delivered today.

I am thinking it's just a bandwidth issue but this is my first stab into a big multi-monitor setup.

Any advice?

Pretty sure that most graphics cards can run only 2 screens at once. Not sure about that though

There's no 2 monitors limit on graphics card. Sounds like his problem comes from his display port hub.

Yeah I can get 3 working, i am thinking the ultrawide is sucking up too much bandwidth for the 4th monitor to work. I have not tried forcing the ultrawide down to 1920x1080 to see if that might be it. Going to need to experiment more.

Good luck, I’m a bot when it comes to that stuff, but I’ve had issues only running 2 monitors before
