Review on 🔀 Yeemie HDMI KVM Switch: 2 Port USB Switch 4K@60Hz HDMI Switcher for Computer Keyboard and Mouse Sharing (Black) by Bobby Posner

I was a bit skeptical because of the low price, but this switch will pass 4k signals at 60Hz. Both HDMI and USB seamlessly switch between two computers. However, this switch seems a bit picky about cables when running at 4k60. One HDMI cable I tried caused the display to intermittently lose sync and go blank. Switching to something else fixed that issue, although the screen was still a bit glaring at times. Also, I don't like that the HDMI output is on the front of the box - a bit odd that the monitor cable comes out the front, then they have to be routed back to the monitor again. There would be less cable clutter if the socket was on the back of the box. Although this device has some features, it works and is very reasonably priced for its purpose.
