GREATHTEK Usb3.0 Kvm Hdmi Switch 4K@60Hz for 4 Computers Share 1 Monitor, Kvm Switch 4 Ports with 3 Usb 3.0 Ports Share Keyboard and Mouse, Support Button Switch, Power and U

Setup: Literally a breeze. Plug everything in and it just works. No drivers or anything. Worked for me on Windows 10, 11 and several flavors of Linux servers. Performance: The switch handles video in an expedient manner. Meaning the switching between machines is almost instantaneous. I had no rendering issues such as screen resolution changes or color funkiness. There is no distortion when inseting this KVM into the chain. I have had other KVM’s where the mouse would lag a bit. That is not the case here. In fact, I was using a wireless mouse and had no lag. To switch machines it is a simple press of a button. Switching is quick and simple. Build: The KVM is made of metal! Nice as compared to a plastic alternative. Cables: The cables that come with the unit are functional, but you may find them a tad short for some applications. Fortunately 6 foot USB and HDMI cables are not expensive. However, in terms of quality the cables are good and present no issues. Conclusion: If you regularly juggle two or more computers at one desk, or have multiple servers in a closet this is the ticket to cleaning it up. Sharing a monitor between 4 systems is a worthy benefit. This unit is priced well and I feel it is a good value in terms of performance.

Funciona bien por unos minutos, y luego deja de detectar los periféricos, y los reconoce de nuevos después de unos segundos. Es muy molesto y parece que le pasa lo mismo a otros compradores de este producto.

I am a technical support person and requiring monitoring of several live client facing platforms. This KVM switch made my job so much easier, now with only one large monitor, single keyboard, and mouse I am able to do my job with one large computer monitor vs four screens! A real game changer for me because I can now switch between 4 different computers effortlessly with the push of a button and don’t have to slide back and forth to each computer. The push button switches quickly, smooth, and responsive. The real hidden benefit is set up with the plug-and-play which requires no effort installing extra software drivers or complications interfering with different levels of operating system. The USB3.0 KVM Switch HDMI 4K@60Hz (4 Port) provides 4K video with crispness and no frequency flickering response issues. In addition, the 3 USB 3.0 ports is beneficial for connecting peripherals like external hard drives, webcam, and printers – once connected all the devices can be shared. Overall, the price is competitive and construction of the KVM switch in rock solid and only requires a small footprint on your desk – not to mention it looks pretty cool – I highly recommend this for technical people trying to simplify their usage of multiple devices.

For the price, you simply can't beat this KVM! It has a nice compact footprint, is super-quiet (no cooling fans, etc.), transitions from session to session smoothly with little lag and uses standard USB and HDMI cables (no proprietary KVM cables needed). My main complaint is when switching from host to host the USB devices are connected/disconnected - this causes the sound for "USB Device Disconnected" to be played on the machine you are transitioning from, and "USB Device Reconnected" to be played on the machine you are transitioning to. Of course this is SUPER annoying, but you can turn off these sounds in the Themes on each of the machines connected to the KVM (unfortunately this will apply to ALL USB Connect/Disconnect actions not just those on the KVM). The sounds can be dealt with, but because of the way the KVM manages these devices you're going to see a LOT of USB Device Disconnect/Reconnect messages in your hardware audit log, and of course this introduces a slight lag when transitioning from session to session. My prior KVM (a Belkin F1DP116G) kept signal to the keyboard and mouse on each host machine active (whether USB or PS/2) so this was not a problem - if this KVM could do something similar it would be a HUGE improvement! Gripe #2 is the location of the 3 USB ports, they are all in the front of the unit. Meanwhile all OTHER cables connect in the back. I think it's great to have USB ports in the front for things you might want to plug in and take out (like a thumbdrive), but could you put at least two or three in the BACK so we can connect the keyboard and mouse (and maybe one other permanent device) in the back and not have their cables visible on the front of the unit? Lastly, the unit is powered by a USB-C cable to an AC power adapter. I have this plugged into a power distribution switch on the same circuit as my monitors. At the end of the day I flip the switch to turn off this circuit to power down my monitors and KVM switch - but the KVM still has power! It must be drawing power from the USB cable to one of the hosts (that is up and running 24/7)! It would be helpful if the KVM would power down when the power supply to it via the USB-C cable is terminated. Bottom line: Great value for the price, seems efficient and reliable - but with room for improvement.

The KVM switch works like it should I have hooked 4 computers to it and able to switch between them effortlessly. The problem I faced was that my gaming mouse and keyboard would "freeze up" for anywhere from 1 second to 12 (the longest one I counted). I realized that the switch did not provide enough power to keep these devices stable. I purchased a USB 3 switch, plugged my mouse and keyboard connectors into that, and that into the KVM. Everything now works perfectly. I subtracted one star for this shortcoming. It cost another $17 to fix an issue that should not exist in the first place. I hope this helps anyone that has the same symptoms.
