Review on TESmart 4K@60Hz Ultra HD HDMI KVM Switch, 2x1, 3840x2160@60Hz 4:4:4, with 2 Pcs 5ft KVM Cables, Supports USB 2.0 Devices, Control up to 2 Computers/Servers/DVR (Black) by John Larsen

I recently replaced a basic VGA switch with this KVM when it eventually broke and bought a new monitor. So far I'm very happy with the performance and have only a few small issues. SETUP: I am using a VGA to HDMI adapter from my desktop PC as my main display and HDMI from my laptop to extend that display to a new monitor. . I use a Logitech wireless keyboard and mouse combo that works no matter which USB port I plug it into. I also have a printer connected to the optional USB port. PRO: The keyboard shortcut works great. The switch makes a pretty loud beep when toggled with a key combo or a button on the switch, but I've read that this can be turned off. There is almost no latency when switching displays, and the ability to use a wireless keyboard/mouse and printer for two PCs is great! CONS: When I switch from my laptop's extended display to the primary display for my desktop, the laptop still behaves as if the second monitor is active. Some people might find this professional, but if I need to use both, I have to switch to screen mirroring on my laptop. Another problem I have is that I get glitches from time to time when using a wireless mouse, and I've read that using an extra USB port can fix this, but I need the printer dedicate to a PC. in this case. The only other minor complaint I have is that the included power cord is very short. I could use another 6-12 inches. I've heard some people say the light is too bright, and that's true, but I ended up setting my switch on the back of my desk and using keyboard shortcuts, so it doesn't bother me at all. Overall a great switch with a simple plug and play setup. The display didn't work at first so I turned off both PCs, turned on the switch and turned everything back on and the problem was resolved.
