I recently bought 2 monitors with integrated KVM switches. I plan on using it with a PC I built myself, and a Microsoft Surface Studio 2 I bought for school purposes. I have left monitor with a DP cable to the PC and my right monitor with both DP and USB to the PC. My mouse and keyboard are connected to the right monitor.
The problem is, when I connect my Surface to the monitor using a USB-C cable I had in my house and press the KVM button, the screen switches to like the "searching for input" mode, the mouse and keyboard restart and are usable on the Surface, but after a few seconds the monitor reverts back to the PC input, not having shown any video and the keyboard and mouse only worked for those few seconds. I tried both USB-C ports on my Surface.
Am I missing something? Or is my USB-C cable not "powerful" enough to transport all three K, V and M? Hopefully someone can help me out!
