Yinker 4K 60Hz KVM Switch HDMI 2 Port, USB HDMI KVM Switch 2 computer 1 Monitor Keyboard Mouse+Cables+ 4 USB 2.0

needed a KVM for switching 5 PC to a monitor in the system rack. Worked perfectly very slight slow on the switch over but at the price its acceptable compromise. The unit comes with a power supply but you don't need the PSU, the KVM takes its power from the USB connections to the PC.

This was the 2nd KVM switch I bought from Amazon. The first is being returned as it didn’t do what it was supposed to do. This one does: switches all 3 of the KVM elements from 1 PC to another in the rack (only 3 in my rack, room to add 1 more to the stack with this KVM switch if needed) with 1 button press. I only needed 1 monitor for the configuration so the fact that this switch can only output to 1 isn’t a problem for me. Where I’ve dropped half a star is because the last thing I added to the configuration was its stand alone power supply. That made everything cut out and refuse to work. But since each PC is connected to the switch with both a DP cable & a ‘printer style’ to USB cable to power the switch, I’m assuming that the 3 auxiliary power supplies are enough and maybe I’d only need the independent power supply (provided) if I had fewer PCs in the configuration? All 3 PCs need to be on 24-7 so the switch always had the auxiliary power supply. The other half star is deducted because the switch couldn’t cope with a Smart Keyboard. I resolved this by using a ‘normal’ keyboard and plugging in a smart card reader into one of the front available USB 2.0 slots. This KVM switch was cheaper than the original & has growth room for one more PC if needed (which the original didn’t) so I’m glad the original switch was not fit for purpose & is being returned because apart from only 1 monitor out, this one worked out a much better purchase all around.

Easy to install, works just as described. Wish I had bought 1 years ago to replace my old PS/2 keyboard and mouse connections.

5 Days after the Switcher arrived one of the channels failed. Now returning item

A great KVM. Used to connect to 4 proxmox nodes. I also have a usb receiver for an mx keyboard on the back usb for input which works well. The front usb can also be used as a pass through port so I can pass physical usb drives through to the proxmox VMs when needing to boot VMs from usb bootable drives. The remote also works well and allows me to switch between the nodes quickly.

Failed quite soon after purchase

It's nice to have one switch handling up to 4 USB devices an HDMI. As instruction suggests the external power is advised. Not so nice: the external switch button has no indication of currently selected input. While it may seem to be a minor issue, it defeats the purpose a little as the whole idea is to tuck all the mess with cables away.

Poor, constant issues with clicking mouse, or not clicking altogether, extremely frustrating!!!
