CKLau KVM Switch HDMI 4 Port wit Audio and 4 kit Cables, 4 Port HDMI KVM Switch Support 4K@60Hz 4:4:4, EDID, Hotkey Switching

This was a great KVM. The hotkeys worked, the remote was responsive, and the cables were pretty well managed.Unfortunately, the mini-usb connector is not wolf-proof. I'm sad to report that its demise came last week, when my 100lb wolf hybrid was sniffing around underneath my desk. She thought about trying to push through some wires, among which was the wire for the remote on the KVM. She decided against it, and then backed up... causing her tail to knock something off my desk. The noise startled her and she jumped forward, which yanked all the wires around and broke off the USB port where the remote connects to the KVM. Naturally, the destruction caused even MORE noise and she went into a full on freak-out, charging out of the room to hide downstairs. I do note that I couldn't stop laughing while this was going on - she kept making things worse every step along the way, like an old Charlie Chaplin film.She still visits my office, but eyes my desk with suspicion. Sadly, once the remote's jack was broken, the KVM stopped doing USB switching for the devices connected to it. So while it's still a decent HDMI switch, it is no longer a KVM.I mourn its loss - this really was a great KVM.

The switch comes with a little USB 120V adapter to supply the unit with 5V. The manufacturer claims that it draws 2 amps, but I have not found any evidence that it draws that much. It also comes with hybrid cables that combine HDMI with USB and analog speaker and microphone. This cable simplifies the wiring although the cables are a bit long. I can live with them. The analog speaker works. I did not test the microphone port. It would be nice if the analog output ports were on the back instead of the front.Switching takes about 5 seconds for everything to switch. The audio and keyboard switch almost instantly, but the video takes the longest to come around. My Raspberry Pi and my MX linux machine had no problem. Windows 7 had some issues but eventually came around.I have a wired keyboard and a wireless keyboard/mouse connected to it. Everything works fine.I do not use the wired remote because there is no need to. Just hit the right control key twice and then press the computer number on the numeric keypad and then press enter. That switches without the fuss.I would definitely recommend this to anyone that wants a KVM.

The price of the unit is more than reasonable, and I was quite impressed with its quality. It has a sturdy metal case that is built to last. Installation was okay. I have three computers on it. I had to do some trial and error to figure out that some of my USB devices wouldn't work on the USB 3.0 connections, which is alright with me. Getting the monitor set up was the biggest problem. I have a 43" UHD tv I use as a monitor. In my first attempt on my main Windows box, I didn't get any video at all. After some more trial and error, I brought up the Display Settings and found the refresh rate was too high. Originally, it was set to 30Hz but it had been changed to 60Hz. That fixed that problem. The biggest problem I had was with my other Windows box. No matter what I tried with refresh rates, nothing would be displayed on the screen. The problem turned out to be that the HDMI cable included with the switch was bad. I'm going to contact CKlau support and see how responsive they are.

I just bought and installed this KVM. Worked great in the beginning, but when I switched away from one PC to another, then returned to the original, the mouse and keyboard were dead. Within a few minutes the computer locked up and crashed. I thought it might be an anomaly, but then it continued this behavior time and again over the next few days. Finally I contacted the mfr. and received a stunningly lame reply. Their solution is to shut down all the computers & the KVM, unplug and re-plug the cables, and restart it all again. Here is their response:Thank you for choosing CKLau.The KVM switch need identify USB device again after switching back previous computer.Frankly, i suggest you reset the KVM switch, step as follows;step 1. turn off KVM switch and all of your computers/laptops, then unplug all the cables;step 2. plug the DC5V 2A power adapter into KVM switch and AC socket, turn on KVM switch(there is a o/f button on the back);step 3. plug keyboard into keyboard slot of KVM switch;step 4. click right [CTRL] on the keyboard 2 times, then click [ESC] 3 times, at last click [ENTER]. (whole operate time should not over 2s, after you hear a beep sound, that shows operate successfully);step 5. plug KVM cables into KVM switch and computers, plug HDMI cable into KVM switch and your monitor; plug mouse into mouse slot of KVM switch; plug other USB deivces into USB 2.0 Hub of KVM switch if needed;step 6. turn on your computers.Please try and share the result with us. Thank you....and my reply: Contrary to this suggestion, why don't you fix your KVM. It is outrageous that you think customers will go through this process almost every time we switch between computers. I will return the product.
