CKLau Dual Port Triple Monitor KVM Switch Displayport with Audio Output, USB 2.0 Hub and Cables Support Extended Display Resolution Up to 4096x2160@60Hz 4:4:4

First, it's ridiculous that Amazon conflates the reviews for every product this company makes as different 'colors' of the same item, when they are vastly different!To the main point, this product, despite what it says on here and the instruction manual does NOT support EDID, therefore every time you switch, there is a long delay while your system re-detects all the screens and all of your windows get shunted off to the first screen. Further, because of this, each switch takes up to 30 seconds to take place, which is completely unacceptable, especially for a product that costs $200. The keyboard and mouse are also fully disconnected, so it's a tossup as to whether or not they'll work when you switch and there is again a full 30-40 second delay as the keyboard and mouse are again detected from scratch. I do NOT recommend this product. Unfortunately the market for displayport-based KVMs are very slim indeed.

I bought this to replace my IOGEAR Miniview 4-port VGA KVM (GCS1744), which I have had since 2006. It finally stopped working (2019). A problem that I had with it along the way was that at some point the powered USB ports on the back stopped providing enough power for my Logitech Performance MX wireless mouse and my Nitehawk X8 mechanical keyboard. It did work when I put both devices into a non-powered USB hub and plugged that into one port.At some point that ceased to work, and I got a powered USB 3.0 hub and that solved the issue.Ok. Sorry for the long setup.The CKLau 2 Port Dual Monitor KVM Switch is a compact unit. Feels very solid. Doesn't take up much space, but it is heavy enough that it isn't being dragged by the cables. The buttons have a crisp click to them and it does the job of switching between my monitors instantly.It is with the Mouse and Keyboard that I again am having a problem. The ports in the back are also unpowered. I do not recall seeing this in the product description. I even tried to use my powered USB 3.0 hub and it did not solve this issue.The user manual does make mention that if you have a mechanical keyboard that you may instead need to use the port on the front on the unit. I plugged in a non-powered USB hub to the front port and plugged my mouse transmitter/received into that and my mechanical keyboard, and it all works just fine -- except aesthetically I really wanted all of the cables coming out the back.I wrote to CKLau about this and there was no reply. Nothing.I don't think there is much excuse in 2019 for a KVM switch not to have powered USB ports in the right places, but I know there is no excuse in any year for a vendor to not respond to my concern about the product.I gave this 3 stars because despite the cable placement, it solved my need to share keyboard, video, mouse, and I can live with the cabling issue. I would have given it 4 stars if the company had at least responded to my issue.

I'm grateful that this product exists and it is precisely what I need for my current setup...sharing between my personal desktop system and my work laptop. However, everything is not perfect. Often, after switching back and forth between systems, I'll lose a monitor, or I'll lose keyboard/mouse, or a combination. It's very frustrating. The switch itself will not reset the connections properly...I end off shutting everything down, re-seating the connections manually, pulling power from the switch, resetting the switch, and bringing up the systems. Right now, for example, I'm using my personal desktop, but the 2nd monitor (DVI) is connected directly because it no longer works through the switch.Also, the price of this switch is high. I'm already looking for alternatives. When it works, it's great, but it doesn't seem to work for me for very long.--UPDATE--Amazon customer service is fantastic. They helped to arrange a return and I re-ordered this switch and re-installed everything. Unfortunately, the exact same thing started happening. The switch worked fine for about a week, and then suddenly I lost my mouse and keyboard, which caused much commotion. Now, the monitor plugged into the DVI port doesn't come up at all, for either system. When I manually plug that monitor into the system I'm working with, it's perfectly fine. I need to research another alternative because this switch has issues. It's not working right at all for me, and this is my second try. I did receive a response from the manufacturer, which was positive that they wanted to help, but their fix did absolutely nothing. Still searching for an alternative (and maybe one that isn't so expensive!).

I went through several cheaper quality switches that didn't quite work as advertised before buying this one. This switch is all metal, solid construction. Hooked up my newer laptop via usb-c to dvi cable and my desktop computer to the switch, with my gaming mouse and wired gaming keyboard. Mouse had to be hooked up with the 2.4GHz dongle rather than bluetooth as bluetooth didn't seem to switch between the two signals properly. Overall, extremely satisfied with my current setup using this switch. Solid buy.

Das Gerät wurde mit inkompatiblem Netzteilstecker geliefert – nicht wirklich schlimm, könnte man ja ersetzen – wäre da nicht die Fehlfunktion, die es zum No-Go macht: auf einem von zwei nahezu identischen MacPro Rechnern setzen Mouse- und Keyboardfunktion alle 10 bis 15 Sekunden für etwa 5 Sekunden aus. Viel Spaß ...

fonctionne super bien, je suis vraiment satisfait par ce produitsi vous utiliser un adapteur unifying de Logitech ne l'installer pas dans les prises clavier et souris officiel mais dans le port usb partagé, et utiliser les commutateurs sur le boitier pour changer d'un poste à l'autre

Everything works great. I can switch between two PCs with three monitors 3. Even sound over HDMI switches over (monitors have small speakers in them). I use the front usb port (the usb hub) for my Logitech camera and that switches too without issues.Switching between PCs is so easy and convenient - double clock of the middle button (scroll wheel), keyboard Ctrl-1-enter or Ctrl-2-enter or the button on the little remote (wired) that comes with the unitNote, that I only tried 1920x1080 modes so cannot comment about 2K/4K. Also I am not using the audio jack switcher but I it likely works tooEverything just works. Good product!

Works great, however the mouse & keyboard do not function occasionally until power is cycled. I like the double click mouse wheel to switch input!
