I have a surface dock 1 that i use with my Surface Laptop 3. The dock is connected to a Kogan 34" 3440 x 1440p monitor and another Dell 27" 2560x1440p monitor via 2x display port to mini display port cable. They are both running at 60hz but the screen keeps going on/off every couple of mintues and i have no idea what's causing this? Is the surface dock the issue and not supporting 2x screens at 2560 and 3440 resolutions?
Any idea if there is another dock that can support 2x 4k displays at 75hz or more?
