CKLauKVM Switch HDMI 4 Port with USB Hub, Audio and 4 KVM Cables, 4 Port HDMI KVM Switch Support 4K@60Hz 4:4:4, EDID Support Wireless Keyboard Mouse

I bought this because I had an old 2-way KVM but want to add a third laptop to be controlled. Saw this, seemed decent value...So far, seems excellent. I have a PC and 2 laptops connected. Using the HDMI (obv) for video and the USB connections on the cables for the mouse and audio, not using the audio and mic jacks on the leads. Mouse and keyboard (both wireless with USB dongles) work fine. Also have a Jabra cordless headset plugged into the USB hub port on the KVM, and that works fine on all devices. I also plugged a small USB hub into that port, and it worked fine.Switching seems good, reliable and pretty quick using the wired remote - 2-3 seconds for the monitor to switch, quicker for the mouse. I'm not using the hotkeys, just using the wired remote for the switching. Good wired remote control, tactile buttons and an LED by each one so you can see which is active.By default, very annoying beep when switching - just make sure you have the button to allow keyboard shortcuts on on the KVM, then you can disable the beep with keyboard commands (and I then pressed the button on the KVM to turn off keyboard shortcuts, I just want to use the remote button).Interestingly, the item seems (to me) to suggest you need to power the thing up with a separate 5V (USB) supply. Mine is working without that, so obviously it can take power from the plugged in devices in some cases. I like that, I prefer the unit to be off when all of my devices are off.Obviously, make sure all of your devices have HDMI video outputs, or get the relevant adapters to convert to HDMI and make sure you have an HDMI cable for your monitor (this comes with cable sets for the inputs but not the outputs).So far, works perfectly, though only been using it a day, so will update this if things change.

Working for a few companies as a freelancer the need to work with multiple devices this is a lifesaver. The ability to use 4 laptops with 1 keyboard , mouse and camera is great. The audio is a bit hit and miss at times as it comes with jacks for headphones and mic. Most laptops nowadays use USB ports so another connection to USB would be ideal.Other than the audio jack issue this is a great assistant to my daily work.

I had this dock installed for a year on under-spec monitors. I then later installed a 60hz monitor and the dock wouldn't cope with it. It would blink black every 10-20 seconds. Very disappointing.Also, clicking the central mouse button three times would swap inputs. This is incredibly annoying when playing FPS games!

Since installation: So far has worked flawlessly. Nice solid construction too. I like the fact it is powered by its included powerpack. The previous KVM I tried would not work with just one computer on and also would drop out occasionally. Very annoying. That KVM was by another company. I was pleasantly surprised at the reasonable price too. Only con is the leads could be a bit longer. But I like the fact that all the connections are via one HDMI lead into the back of the KVM and then video, USB audio. Microphone are all behind the computer. Using with a Logitech wireless keyboard and trackball combinations and installed with no problem.I've just ordered a second one for my setup in my upstairs computer room So here's hoping the KVM remains reliable. Would like to know if longer leads are available.

It is a tidy sturdy switch, made of metal, works well and delivers great picture quality. One point of note, on first setting up, the displayed image over filled the screen - at first I thought this was a switch fault. I later found an image display size adjustment option on the display device, after which all was well. Easy to set up, just plug-in and use. Note that a USB power point / adapter is needed to supply the power.Plugging in a webcam to one of the USB2 ports (mouse) caused the switch to malfunction, but using a USB3 port was fine. This might be down to not fully understanding the mouse switch / hotkey settings ... which might be confused when using a combined keyboard / mouse wireless dongle.The reason for just a 3 star rating is that the product illustrations appear to show that the HDMI and USB cables are conjoined, a key characteristic for choosing this product. They are not, further the USB cable is significantly longer than the HDMI cable leading to a total rat's nest of messy cables (eight in total), requiring further expense for cable management solutions. Provision of conjoined HDMI and USB cables would give this product an unqualified 5* rating.NB: If using with closed laptops, remember to change the laptop power settings to not go to sleep when the lid is closed!!
