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!*

Works great! Used to connect my work laptop on one side and personal desktop on the other side. Switches over seamlessly re-connecting my keyboard, headset and wireless mouse.

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 have a 3440x1440, 144Hz widescreen. The KVM works well.I do recommend connecting a power brick to the USB-C power input to avoid problems (if you turn off one PC, and switch the box to it, it won't have power to switch back).For those of you using this in a setup with dual monitors on one of your two PCs, BE AWARE that this KVM does not emulate a connected monitor on the PC that is not currently selected, so all your windows and icons will move to the 2nd monitor. The only KVMs that do emulation are far more expensive than this switch, and a lot more than I'm willing to pay for.If you need longer DisplayPort cables (as I did) you need good quality, well shielded cables, to avoid problems. The ones I used I bought here on Amazon: The "VESA Certified DisplayPort Cable 1.4, Maxonar 8K 5ft" cables. I also bought a 1.6 ft version of the same cable for the short jumper between the monitor and the KVM, since the KVM sits right under my monitor.Only reason I took off one star was for the lack of monitor emulation, and not including a power brick and cable for the power input.
