Review: Four years of service, cut short by my wolf hybrid - 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.
Review: Nice KVM switch, cables a bit long. - 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.

## Questions & Answers

**Q: Does this support uhd 4k, ie: 3840x2160/30p ?  another kvm i bought that claimed 4k support only supports 1080p/1080p 3d ...**
A: Keep in mind that the video card and the monitor has to support 3840 x 2160 4K resolution 
I have mine connected and I get 2560 x 1440 which is the max resolution that my monitor supports. Check your video display settings in your computer to find out what is the recommended setting that windows found for your display.

**Q: Does the switch “proxy” edid information when the host isn’t selected to talk directly to the monitor?**
A: Its supposed to, but I have not found this magical 1080p/auto edid button that the manual keeps mentioning.  So my lg ultrawide is stuck on 1080p for all 4 of my pc.

**Q: Will this work with a microsoft surface pro? does it come with the cables i will need?**
A: NO - you would have to purchase more.  All Surface Pro's only have 1x USB port and 1x mini-Display Port (not HDMI).  You would have to purchase a mini-DP to HDMI video adapter (less than $10) to use it with this switch.
Microsoft does sell a port replicator (~$150), but it also only has mini-DP video ports (so it does NOT help you to buy that).  "Orion" said "Micro Surface Dock" could plug into this KVM,  but only "later" said that you still need a video adapter.
If you need this HDMI KVM switch, the easiest/best/cheapest thing to do would be to buy a simple "mini-DP to HDMI" video adapter and plug the (now HDMI) and USB into this KVM switch.

**Q: Is there a published instruction manual? I cannot seem to switch from windows 10, raspberian, or ubuntu. What are the keyboard and mouse commands?**
A: A user manual should have come with the unit which gives keyboard hot-key switching codes. Double clicking the mouse scroll wheel should step you through the ports. You can also use the manual button for switching toa port.

### ⭐⭐⭐⭐ Just installed it. Overall, it's working well and I'm very pleased.
*by D***D on January 25, 2024*

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.
