UGREEN 8K Displayport KVM Switch 2 in 1 Out DP1.4 with 4 USB 3.0 Ports(3 USB-A + 1 USB-C) Support 8K@60Hz 4K@240Hz Share 1 Monitor Keyboard Mouse U-Disk Printer, with 2 DP Cables, 2 USB A to C Cables

First Day of Use: This little guy is so far perfect for my setup! Extremely easy install for connecting my iMac and MacBook Pro to a LG Ultragear 38" monitor, along with an apple keyboard (wired via USB-C), a G502 gaming mouse, and a Wacom Intuos Pro tablet. Now I can use all my best/fav peripherals seamlessly between both computers.As a bonus, the LG monitor has a built-in USB hub, so I was able to plug that into the KVM switch via USB-A and have my desktop speakers plugged into the back of the monitor, and now I can play music from either computer thru the speakers via the switch/monitor hookup.I did go ahead and get a USB-C cable and wall plug to power the switch as it does not come with its own power cable, and some reviews mentioned that it didn't get enough juice from just the two computers to power it properly. I also had to get an extra USB-C to Displayport cable because the MacBook doesn't have a standard Displayport plug. In total I spent $90 for the switch and 2 extra cables, totally worth it and way less than a lot of KVM switches out there.I'm able to get full resolution at 144Hz on both machines with no issues (so far). As long as the switch continues to work as well as it has out of the box, this thing is a huge time and headache saver. No more multiple keyboards or mice, and no more unplugging/plugging cables!*

The installation process was flawless, seamlessly connecting a Windows desktop to an Apple MacBook within a mere ten minutes. Previously, I had encountered difficulties with a different brand’s product, which had not functioned as expected. Despite the frequent returns associated with this particular item, my positive experience with the UGREEN brand prompted me to give it a try. Despite some negative reviews, I am delighted with the product and would highly recommend it.

I "thought" that I was going to have to return this KVM, but once I used the provided cables (instead of my crappy old cables that were already in place) it works great! It turns out that the quality and length of your cables make a HUGE difference when you are trying to squeeze top performance out of a KVM. I have a single 4k monitor that I share between a work laptop and a personal desktop for gaming. I wanted to run the display for my desktop at 120Hz or faster. When I first connected everything up, I just used the existing Display Port cables I already had running from both the laptop and desktop, but I got this weird glitch where the monitor would periodically (at least once every 2-3 min) go completely black for 2-3 second, then recover. That's totally unacceptable for any sort of gaming. I tried all the refresh rates (all the way down to 60Hz) and the problem happened for both my work laptop and gaming desktop. I was just about ready to write a terrible review and return it, when I noticed the nice new DP cables peeking out of the packaging, with the little 4k/8k logos on them. So, I shut everything down and swapped my old dusty (and apparently low-end) cables with the ones that came with the KVM and Shazam! It works perfectly. I highly recommend it, but you really need to use the cables they provide if you want good performance. I would absolutely buy it again. It's been flawless for about 2 months for me.

I had high hopes for the UGREEN 8K Displayport KVM Switch, but it has been one of the most frustrating gadgets I’ve ever purchased. This device is marketed as a cutting-edge solution for those seeking to switch between multiple computers while using a single monitor, keyboard, and mouse, but in reality, it falls tragically short of its promises.First and foremost, the installation was an absolute nightmare. The cables provided were poorly labeled, and the instructions were next to useless. After wasting hours trying to set everything up, I was greeted with a complete lack of functionality. The switch would arbitrarily fail to recognize my devices, and when it did, the outputs were consistently glitchy and unstable.As for the promised support for 8K@60Hz and 4K@240Hz, it was a complete letdown. I connected everything according to specifications, only to find that my monitor displayed an error message, and the expected resolution never materialized. Instead, I was stuck with lower resolutions that were not only disappointing but also rendered my high-definition investments pointless.The USB ports were another disaster. The KVM switch boasted four USB 3.0 ports, which I assumed would allow me to connect all of my peripherals seamlessly. Instead, I experienced constant connectivity drops and lag when attempting to use my keyboard or hard drive. I could hardly make it through typing a simple document without the keyboard freezing or the printer failing to respond.Additionally, the overall build quality felt cheap and flimsy. I expected a product at this price point to be durable; instead, it felt like I was handling a toy. After only a few uses, I noticed that the HDMI and USB ports were already showing signs of wear.Customer service was no help, either. My emails went unanswered for days, and when I finally received a response, it was generic and lacked any real solutions. It seems they are more interested in making sales than supporting customers with defective products.In conclusion, the UGREEN 8K Displayport KVM Switch is a dismal failure. If you value your time, money, and sanity, look for an alternative that actually works. Save yourself the headache and avoid this product at all costs. One star, and that’s being generous!

Dropping 1 start because this is not new. The packaging has obvious been previously opened.This device however is working so I will keep for a few days to insure it works as expected.So far, the setup was easy and it is working as I hoped it would allowing me to switch using my keyboard and mouse between my desktop PC and my Mac laptop while sharing a second monitor between the two.
