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.

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.

Quick review:The product itself is great. Well built, sleek as a KVM can be and good quality cables. The only negative I can say about it is that the remote doesn’t have any way of showing which input device you’ve switched to. This is genuinely the only change I think it needs.Considerations:- this is not a thunderbolt KVM and you need to use both a display cable and a data cable for each device- you cannot use a HDMI output from a MacBook Pro/Mac mini/ Mac Studio unless you use an active HDMI to display port cable (I wouldn’t recommend this option but have shared a better alternative right below). A normal DP to HDMI cable will not work.- If you connect a MacBook Pro I’d highly recommend that you use a USB-c thunderbolt cable to display port cable (1m)- if you have two displays or want thunderbolt you’ll have to buy a more expensive device- this thing isn’t pretty. You’re going to want to jam is somewhere out of sight, hence why the remote would benefit from visual feedback indicating which device was active.Over all great product, and sharing these considerations as so many others kindly have in the reviews.

Really good KVM, only returned due to weird screen flickering when connected to a 4K screen. It could have been a faulty unit… in any case I really liked everything else about it, decent quality build, full metal enclosure, quality display port and usb-c leads where supplied, to top it all off, the price was less than £50 for a 4K KVM, which is a no brainer for a home office setup. If you have two computers and one decent screen, then look no further. Easy to install, good quality, plug and play, no additional power source required for a great price.

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.

I use this to switch between my work laptop and home PC to connect with my two daisy chained monitors. The USB is also fed to my monitors where I connect my peripherals. Quite a neat setup.It does require sufficient power through the USB-C connectors to work correctly, so either connect a dedicated USB power supply or ensure that the source USB provide the require power.

I have had many other small kvm switches, but so far this one seems to do exactly as I hoped.My key demand was to enable 2 devices with one set of controllers, I have 2 screens, chained using mst, all no problem.Very happy with this device.
