UGREEN 8K@60Hz Displayport KVM Switch, DP 1.4 KVM Switcher Support 4K@240Hz, 4 Port USB Switcher for 2 Computers Share Keyboard, Mouse, Hard Drive, Printer and 1 Monitor

I use an Apple MacBook Pro M! for music production and as my daily driver. I also have a Windows Rig I built myself for gaming. Running a 4080 super and AMD 7800X3d. My Monitor is an LG UltraGear 38 Ultrawide, running at 3840x1600. It has a refresh rate of 165Hz with overdrive. But I run it at 120Hz as it gives me 10 bit colour. It is GYSNC compatible and so provides variable refresh rates across the full spectrum. It is also HDR 600 Compliant.I am connecting wired Razer BlackWidow Pro V2, and a Razer Mouse. (Don't judge, I love the RGB!).I was looking for a device that could swap between both devices, making my life considerably easier then it was faffing around changing the input on the monitor, swapping over the keyboard, etc. I was dubious about this device, because I was asking for a lot.However, I can safely say, it all works.Working on the PC Side :* GYSNC passthrough works perfectly, I get variable refresh across the range* HDR passthrough works perfectly. I still get HDR compliancy via the switch* 165Hz at 8 bit colour, 120Hz at 10 bit colour, at 3480 x 1600 (native), works flawlessly.* Both Razer Keyboard and Mouse are detected and work flawlessly as though they are connected natively.* Previous Logitech Dongle (MX Keys and Mouse Master 2s) also works perfectly.Working on the Mac Side :* HDR passthrough works perfectly. I still get HDR compliancy via the switch* 75Hz VRR works perfectly. This is the maximum my dock provides via Displayport* Both Razer Keyboard and Mouse are detected and is recognised via openRGB (great software BTW), and colours can be changed.Additional Notes :I did think I would need to supply the device with additional 5v power due to the RGB keyboard and mouse being connected. To my surprise, this was not the case. This may be different if you're using Corsair Devices, or Logitech, or SteelSeries RGB devices. If so, I can't see why they wouldn't work if you provide them enough power given my Razer Devices work without it.You will need you're OWN power cable though if you do require additional power;Contents :2 x USB A to USB C cables.2 x Display Port 1.4 to Display Port 1.4 Cables (Backwards compatible) - And yes, they are DP 1.4 compliant!1 x USB remote control cableThe DP cables are very short at about 3 feet. Bizarrely the USB cables are another foot longer. Still, they are excellent quality cables.The unit itself has some weight to it. Is certainly DP 1.4 compliant and is very well made. The remote control is quite long, but isn't up to the standard of the rest of the device. Merely functional and acceptable. There is room for improvement. I may decide to make my own as a fun project.Additional Notes for Mac Users :I see there are quite a few negative complaints from Mac Users saying this device does not work with their device. That might be down to what dock you're using. Or you are using the wrong type of cable. Or you're confusing Display port with Thunderbolt as they are NOT the same. This is a basic DISPLAY PORT switch. A Thunderbolt switch WILL allow Video Passthrough via your USB-C connector. However, you can basically double the price of that device, if not more. You might be better off using the HDMI version of this dock if you're having problems. But if you're expecting to get video passthrough on a basic Display Port switch that isn't Thunderbolt, then you're not going to have much luck I'm afraid. Just an FYI. Blame the USB/Thunderbolt corporate overlords standards committee for not making this clearer.Conclusion :If you have TWO DP compliant devices, want HDR, VRR, Gysnc, and High Refresh rates at high resolutions, then this is a GREAT device for the price. I was very surprised it provided all of the above. I was expecting to pay a LOT more for a more compliant device. (You're looking in the hundreds of pounds to be honest!).I was very surprised at how good the build quality of the unit is, how good quality the cables were, and how competitive the price is. Very pleasantly surprised in every aspect. I recommend.

UGreen continues to knock it out of the park with their computing accessories.This device does exactly what it's described, is well built, compact, and easy to setup.I use this to switch between my gaming laptop and my Macbook Pro. It works flawlessly when switching inputs, and it's been perfectly capable of handling 3840x1600 at 175hz with HDR.Highly recommend!

Works fine at 4k 165hz, for some reason there are very few options on the market that actually delivery at 4k 165hz, this does it. Great product.

This is a nice little KVM, but it comes with a few limitations you should be aware of. Before I get into that, I was instantly impressed by the build quality. It's surprisingly small, looks sleek on your desk, and has some weight to it, so it won't slide around when you press the switch button.It comes with two USB-C to USB-C cables and two DP to DP cables and a wired remote switcher so you can hide the KVM itself if required. The DP cables are short (1m), but I assume this is because the DP specification states that 8K@60Hz requires 1m or shorter cables which is exactly what the KVM is advertised to support. Selling it with longer cables would probably have caused users to claim the KVM wasn't working as advertised. The USB-C cables, however, are longer—I think 2m—but I didn’t measure them.Now, on to the limitations. If you’re looking to buy one of these, you are most likely more of a power user and need to be aware of a few things. I run the KVM to control a Windows 11 PC and a Mac Mini M4 Pro, as I game on the PC and do everything else on the Mac. This means I generally leave one or the other alone for an extended period of time, and this is where the first problem comes in.You can't wake a hibernating or sleeping device (PC or Mac) when you switch over to it from the active computer. If, while gaming, the Mac goes to sleep, I have to press the physical power button on the Mac to wake it—mouse or keyboard input will not wake it as the input has been severed, so to speak. The same goes for the PC. This behavior is confirmed by Ugreen support and is not a defect but a limitation of this KVM. Some much more expensive KVMs will apparently keep the connection between the KVM and the computer 'alive' even when the computer which is not the active KVM target goes to sleep, but sadly not this KVM. You can, of course, set the sleep timer to be several hours long or even disable it, but that's far from ideal from a power consumption point of view if you’re like me and rely on sleep mode instead of powering off your devices.The second issue I’ve found, which may be linked to macOS software, is that switching from Win11 to the Mac doesn’t always trigger the display to activate, even when the Mac is not sleeping. Switching from Mac to Win11 always works however. I can’t tell if this is a Mac issue or some issue with the KVM and Ugreen support has not been able to confirm either or. So it’s something to keep an eye out for if you try this KVM and you use a mac or two.Another point for Mac users: as other reviewers have also pointed out, note that while your Mac has Thunderbolt (which also supports USB-C DisplayPort mode), the KVM does not support Thunderbolt. In other words, you’ll need one cable for the display to KVM and one cable for the keyboard/mouse to KVM—you can’t use a single cable from the KVM to your Mac for both display and peripherals.For PC gaming, there is no noticeable input lag, and G-Sync works flawlessly through the KVM switch. I have a wired Wooting keyboard and a wireless mouse with a dongle plugged into the KVM, and it all works flawlessly. It’s just a real shame that you can’t wake sleeping devices when switching over to them and that the Mac switching is a bit flaky. Do note that you can wake the active KVM device if it went to sleep just fine (as the USB hub connection is never severed), so it’s just switching over to a sleeping device that requires the power button to be pressed to wake it.Update: After replacing the UGREEN DisplayPort to USB-C cable that I also ordered with the KVM with a cable from another brand, the switching issue to the Mac Mini has gone away which is great. The wakeup issue still persist as its a hardare limitiation.

So, I was super excited to use this, but unfortunately I cannot.It looks and feels fantastic with decent build quality, however, plugged in to my PC only it works like a dream. HOwever, plug my laptop in and nothing happens for the laptop screen.I would assume that simply plug both USBs, both video outputs in and should simply just work. Switching to laptop, screen is just black and screen says "no input". Switching back to desktop, and screen comes back. I have tried with a few laptops to check if there is a issue with the laptop, but its not.Desktop is connected with cable that came with KVM.Laptop is connected with HDMI to Displayport cable (by UGREEN). I have tried different cables. I have also tried DP cable with a HDMI to Displayport convertor without luck. Laptops (3 of them) are all HDMI and none of them are able to get video on to the screen.
