CKLau 4Kx2K@60Hz 2 Port Displayport KVM Switch with Audio and Cables, DP 1.2 Dual Port KVM Switch Displayport for 2 Computers Sharing Single Keyboard Mouse Monitor

Let’s say you have a work computer and a play computer and you wanted to use the same computer accessories with both systems simultaneously. How would you do it? Sure you can purchase a bluetooth mouse and keyboard that can pair and switch between different platforms, but what about the speaker systems or the monitor? I’ve come across these scenarios a few times over the years and a port switcher has always been the best solution. After reconfiguring some of my setup last month and consolidating two setups onto one desk I found what may very well be the best Displayport switch I’ve come across to date. This is the CKLau 2 Port KVM switch that basically does everything you need a switcher to do without breaking the bank.At only $69.99 at the time of purchase, this switcher was one of the only ones on Amazon that had audio and microphone support. This means that you could plug in your speakers and use them for both computers. This was a huge deciding factor for me as I wanted to use my JBL reference speakers with both my Mac Mini and my Cyberpower PC. Your accessories are all plugged in on the front side of the switcher. On the 2 port model I have, there are two USB-A ports for a keyboard and a mouse alongside microphone and speaker slots.The back of the device is where all the chaos comes from. I say chaos as it does seem a little daunting at first, but once you get a grasp for the purpose of each section, it basically sets up itself. Segmented into three sections, the KVM switch has an On/Off toggle next to the DC5V power plug. There’s also a slot for an optional wired remote to plug in here as well. The DP Out port is where this switcher connects to the monitor that both computers will be using to display on. CKLau supplies all the cables required to get the system hooked up, including these USB slots that plug into each respective computer. Once those are plugged into their computers, the KVM switch will be recognized as an accessory extension. This is how the mouse and keyboard are connected to each computer. The same applies to the DisplayPort plugs. Once there is a link between the KVM and their respective computers through the DisplayPort, the switcher can push up to a 4K resolution at 60 hz refresh to accompanying monitors. I actually don’t have a 4K monitor setup and I don’t use this switcher with a monitor. I’ll explain why next.As I said in the intro, my main purpose in purchasing the KVM was to allow for the ability to share a single speaker system on two computers. You’d be surprised how difficult it is to accomplish something like this even for someone with decent tech knowledge. I’ve used multiple USB switchers in the past and they always only supplied USB ports and HDMI ports to work with. The reason I’m not using the KVM with a monitor is because I want to view two monitors concurrently. Oftentimes I’ll have a video timeline or an audio timeline I’m editing with my Mac Mini. During rendering or exporting downtime, I wanted to direct my attention to my gaming PC without losing sight of my work. If I were to utilize only one monitor, the KVM would jump between the two computers, never showing both at the same time. This particular switcher also doesn’t have monitor daisy chaining capabilities.While the KVM does a surprisingly terrific job doing what it’s intended to do. Press the select button on the front and the switcher instantly does the job. A green and orange light indicates which computer you’re currently connected with. However, it unfortunately shares a common problem all USB switchers have. With all these mechanical cabling in such a cramped vicinity of one another, static interference causes a humming sound from the speakers. I’ve seen this before on my other switches and it’s usually caused by RGB keyboards. If the RGB is turned off, the humming goes away. That’s something that I have yet to find a better solution to other than turning the RGB off.Another surprising thing about the KVM is the build quality of this Chinese made product. It’s a metal body that feels sturdy and non-intruding. Unlike a lot of the cheap plastic switchers, I don’t have any doubts that the KVM will last a while. I’m quite satisfied with the speed of which the KVM operates at and other than the static interference humming, this is the exact product I was hoping to receive. It’s very rare that something does the job exactly as you wanted it. This is one of those products and well worth the money I paid to do it.

This box is very well made. That's the only positive.I have a triple WUXGA @ 60Hz setup. This is the setup I have on multiple machines including work and home. When I plug this device in, it fails to display anything, but knows something is there. I then tried to hook up just a single monitor and it wouldn't work. It is unable to handle a single monitor with 3 M pixels at 60Hz. If it can't handle this bandwidth - there is no way it can handle the advertised specs.Furthermore, it uses the very very very old mini-USB standard - which was replaced over a decade ago with micro-USB - which itself has already been deprecated in favor of USB-C.The presence of these ancient USB ports probably leads me to believe that this box is using decades old DP standards- which means it is unable to handle the modern DP standard and resolution it claims in its advertising.I can imagine that this box would work fine with the technology that was around when mini-USB was the dominant connector - plus the DP standard of that time. However, their advertising and description claim up to date standards with 4K @ 60Hz operation. It is unable to handle even a single 4K monitor at that refresh rate switched between 2 computers.It is unable to pass through a signal from the DP of any of my computers. For a KVM switch that is a basic fundamental function.Very disappointed.

Hey,I needed a KVM switch to switch between my work and personal computers.I have two displays daisy chained together with a single DP input.This KVM switch is built like a tank and it also supports MST (Multi-Stream Transport).It works like a champ!

This review is for the cklau 2 Port (2 Switching way unit)This unit does not! I repeat, It does not support DP1.2 as claimed here, the difference is that since it only supports DP1.0, you will only get 4K image @30Hz. That being the case, i don't see the point on paying a lot more for using the DP connection over HDMI. Any other KVM switch which only uses HDMI interface would give you the same image specs, 4K@30Hz, and it would cost you less than half of what this cklau unit costs. Sellers are not being honest on their description of their items! So please be aware, and save yourself a lot of troubleshooting, headaches and loosing money.

A nice metal box that houses a KVM incapable of 2k4k@60Hz. The signal is completely unreliable between devices that work perfectly without the KVM in the middle and with cables I know are compliant. Seems to work at 1080p... most of the time.

Was missing a cable with the package. Customer service quickly sent the missing cable.The product works great. Look forward to doing more business with them in the future.

Two computers, one monitor, wireless keyboard and mouse. One click of the little wired remote (I mounted this under my desk) and I can switch from my work laptop to my home computer. Excellent product, quality cables included!

Windows機とMacBookで使用しています。Windows側はHDMI→DisplayPortの変換アダプタを介して接続していますが、安定して表示されます。MacBook側はBelkinのドッキングステーションを介して接続していますが、不安定な状態が割とあります。主な症状としては、切り替え時に画面が表示されない、画面がズレる、時折横線がチラチラするようなノイズのようなものが入るといった具合です。もしかしたらドッキングステーションとの相性か、そもそも此方の機材以外に問題があるのかがあるのかもしれませんが検証しきれていません。ただ、機能は必要としていたものが全て含まれているので割と気に入ってます。
