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.

There do not seem to be that many DisplayPort KVM’s on offer. I was particularly attracted to this one because unlike numerous other KVM solutions this product supplies two DP leads in addition to 2 USB leads. The DP leads are very chunky – (note : quite short – 1 metre) and seem like high quality. The price at review time was £47.99 (owing to a 20% offer – previously £59.99). Even the cheapest DP-DP cables would add considerably to the cost if not included, so I think this is very good value.This unit doesn’t come with a power supply, but for me this was a plus. The power is suppled via a USB port and I am more than happy to run a USB cable supply from an existing USB port rather than sacrifice a mains socket for another charger.The unit is made of metal and is very compact. I was not sure from the description if it came with a remote control. I decided I wanted to try this one regardless because of the other features, but as it turns out it does indeed have a remote switch which plugs into a micro USB socket on the front. One minor criticism: the labelling of the different ports is very hard to read. In use though they are fairly obvious so the labelling is not really that important.To reduce cabling even more, I opted to use a wireless keyboard/mouse combination rather than using my usual wired keyboard. The small wireless dongle sits in one of the front USB slots and that’s it. This all works very well. One thing to note though, if the un-selected PC goes to sleep when sharing the monitor using the mouse/keyboard does not wake it. I have to lightly press the power button to wake the machine. This is slightly annoying but not too bad when you are aware of it. I removed the remote button – again to remove unnecessary cabling. The button on top of the unit is no less convenient than using the remote, so again an opportunity for less wiring clutter. Obviously useful to have though if you are siting the KVM somewhere less accessible / out of sight somewhere.The device is not only “plug-and-play” but also “fit-and-forget” if you are not using the monitoring sharing; you forget it is there since the principal PC in use starts up as normal. For me, this is exactly how it should be.Summary – a stylish little unit at a good price. It absolutely helps with my project of running two PC’s side by side as I migrate a lot of legacy software from an old Windows 10 PC to a new Windows 11 machine.
