Just doesn't work, I added another display to my setup, both displays are Acer Predator 4k 60hz. Both run smoothly at 60Hz when connected directly to my GTX 1070. I have good quality DP cables, everything is plugged in but the displays flicker on and off for a few seconds then one stays off until I plug it back in. It also appears to be running at 30Hz, but it flashes on and off. I'm coming from Level 1 Techs 2x1 DP (they made a video on why it's hard to make a KVM that does this, it's no real surprise). didn't work, I didn't have high hopes) which worked great and was one of the few KVMs that ran at 4k60. They were sold by KVM 4x2 which is why I went with them. I'm returning now
