Cable Matters 3-Port USB-C to MST Multi-Monitor Hub
I'm on Windows 10 Pro.
I am able to connect my 2 PD2700 to the laptop through the docking station and have the laptop screen up. So I am able to get 3 screens working. I don't need the cable matters hub to make that work. I believe my monitors support Displayport 1.4 but I'm not sure that I can make MST work with them because they don't have a Displayport out.
Today I tried to connect one of the older 24" Benq monitors but when I connected the third monitor I lost the laptop screen. Even if I reduced the resolution on all monitors to 1280 x 768.
Is it possible to get the 4 monitors and the laptop screen connected with this equipment? If not but it is possible with different equipment, what equipment do I need?
