How to get 1080p 144hz from second monitor connected to laptop

[rupert413]

Hello all,

So here is my situation. I have a Gigabyte Aero 15x (new one with 1070 Max-Q and 8750H) and two monitors: Asus PG278QR (1440p, 165hz) and Asus VG248Q. I have the PG278QR plugged into the mini displayport on the laptop. I was wondering how to get the VG248Q to run at 1080p 144hz. Would a displayport splitter of some sort work? Some sort of hub? Any suggestion would be great, thank you!

1440p 165 Hz uses the full bandwidth of the DisplayPort link. a hub will not work in this case. If you don't have a second DisplayPort output on your computer, there is no way to get 144 Hz on the second monitor.

Would this cable work?

Technically yes, but Thunderbolt 3 ports are typically driven by the CPU's integrated graphics, so you won't get the power of the graphics card from it.
