Review on GREATHTEK KVM Switch HDMI Dual Monitor Extended Display 4 Port: 🔁 Hotkey Switch, UHD 4K@60Hz Resolution and Downward Compatibility - Complete with Cables by Stephen Parkell

Stopped working after 2 days. Locked keyboard on a system, required reboot to work. On another system, the screen disappeared completely at the same time. Garbage. I wanted to use wireless keyboard and mouse buttons in the keyboard and mouse ports but that doesn't work. Works until you switch screens. Then fails unless you check again for hardware changes in Windows. However, this is not possible if you do not have a keyboard and mouse. I had to connect a wired keyboard and mouse. blah. And when I switch from laptop to desktop and back to laptop, the windows on my monitor go back to being small as if they were on my laptop screen and not my 34 inch monitor. So I have to resize the window every time I switch back to my laptop. Stupid. Return.
