I've only had this for a few days, but it's working out great so far so long as you know the limitations. I'm running 1440 @ 170hz with HDR and AMD FreeSync, which is the maximum spec of the monitor. It handles it like a champ. I'm also running an old windows 98 computer through it via vga to DP active converter 1024x768 @60hz and that comes through just fine as well. Windows 98 does NOT recognize the usb device (good luck finding drivers), so I had to put a known working usb hub in between, and now I have my corsair mouse and keyboard playing starcraft 1 from the orignal disks. The audio does pass through the displayport to the monitor. It sounds fine. The 1/8" speaker/headphone connectors are a separate audio path, so you could plug an aux cable into your sound card and use that exclusively for a communications headset plugged into the front of the kvm while you use the monitor's speakers for general computer and/or game sounds. The body is solid and is only as big as it needs to be for all the connectors on the back. Mounting ears I used to screw it down directly to the surface of my desk so it doesn't move when I push the buttons. The remote also works surprisingly well, and unlike some other options out there the remote comes with a battery. The front buttons are a soft rubber feel, and the click and beep are kind of satisfying. I like having all the status lights on the front, though some might find that annoying. The power cable screws into the back so it can't be accidentally removed. The unit comes with 4 USB 3.0 A to B cables, but no displayport cables. There are other brands who sell this same device under a different label that do not include the usb cables. I ended up using mostly usb 2.0 cables anyway though because I needed more length and I don't need the performance for the mouse and keyboard. Overall I'm very satisfied with what it does especially considering the cost, and I accept the limitations that i'm going to mention below. The keyboard and mouse ports on the back - these are only useful if you have basic keyboard and mouse. If you have a fancy keyboard with lighting, macro keys, volume controlls, etc, it may not even work at all. Same with the mouse. The reason is because the KVM has to intercept the signal to watch for the keyboard hotkeys and the mouse traversal switching. This basically breaks non standard keyboards. Since I am not using a standard keyboard, that makes this port useless. I also do not want the mouse traversal switching (who thought that was a good idea?), so that port is useless also. This device would have been perfect if they would have just saved some money and made the back two ports part of the USB hub that connects the front two usb ports. It works perfectly fine plugging the keyboard and mouse into the front, but it would have been nice to have them plug into the back instead of the front and maintain two spare ports for any other devices I might want to connect. The second con is the KVM does not maintain a phantom monitor when you switch away from a computer. I knew this going in, and devices that do have this feature cost four times as much or more, so I can't really complain, but you should be aware of this. When you switch away from a computer, the computer will remove the monitor/display from your desktop configuration. If you have multiple monitors, your windows will get moved to the remaining screens, and depending on your operating system they may not move back when you switch back. You can buy a displayport EDID emulator to keep that display active, but they are not cheap. ... show more

TL;DR: Exceeds my expectations at this price point. 1440p at 166Hz with variable refresh (GSync compatible) working without issue. I'm not using the audio connections and can't comment on their quality. The biggest negative is the dedicated mouse port on the back with mouse-based switching that can't be disabled, resolved/worked around by connecting the mouse to a front port. Details: Device does not send EDID info to connected computers on its own, info is passed directly from the display. This is potentially beneficial in that you aren't limited by the available resolutions/refresh rates offered by the KVM; My 1440p 166Hz display works flawlessly through this KVM. This is potentially detrimental, because when you switch computers, the computer you don't have selected will act as though the display has been unplugged. If you have more than one display connected, items on the KVM-connected display will shuffle over to the non-KVM display on switch. This isn't an issue for my use case, but may be an issue for yours. There's no way to disable the mouse-based display switching function when using a mouse connected to the rear mouse port. This can cause issues in fullscreen applications without a visible pointer, particularly first person games, as the switch can still be triggered while the application is running. In addition, I use Synergy to share my keyboard and mouse with another computer, with the display located to the left of my primary. Mouse-based switching is supposed to trigger on the right edge, but using the mouse port still prevented Synergy from functioning properly. Moving my mouse to one of the front ports resolved the issue, but it isn't ideal, so -1 star. I saw other reviews note that only basic mouse functions were available when using the mouse port, but I didn't experience that. I use a Logitech G502 in 'on board' mode so that I don't have to keep the G Hub software running all the time, and the additional functions I configured (volume control, etc.) still work as expected through the mouse port. Your mileage may vary, and if your mouse requires constant communication with its control software to achieve customization, you'll certainly have issues if that software isn't running on both connected computers, and might have issues even if it is. The included USB 3.0 B to USB type A cables are pretty short, less than one meter. I only had one longer 3.0 B > A cable, but was able to use a 2.0 B > A cable for the secondary computer without issue. The included power adapter is similarly short. Front LEDs are of reasonable brightness. I'll still probably put dimming stickers on them at some point, but I'd only consider it necessary if the unit was located at eye level. The LEDs are slightly recessed in the housing, so when viewing from above or below, brightness is reduced to a level that I don't find distracting. ... show more
