Review on 💻 DisplayPort DP KVM Switch 2 Port 4K@60Hz - Button Switch, USB 2.0, DP1.2 - No Power Adapter + Cables by Joe Martin

After configuring the device, video switching works fine, no flickering. I've had video issues with several other devices, but this works great. Mouse movement is jerky at times, but that's not a problem for me. I use a Logitec wireless mouse and keyboard. The original module that was sent to me had very erratic mouse movements. After contacting the seller I was quickly sent a new unit and it works much better. Update: Mouse movement became so erratic that I had to use a separate USB switch. Also, when connected to my main laptop monitor, the screen flickers quite a lot until I switch to another laptop and then switch back. In general, I now only use the device for video and not for USB connections. Update: After re-pairing the Logitech Unifying receiver with the mouse, it works fine. Update: August 24, 2021 The mouse worked all day without any problems. But the next day the mouse started to freeze again. Ugggg.Update 8/25/2021 While I can still use the switch for video, I had to use a separate USB switch for the mouse. I increased the star rating because the seller was very helpful and eventually offered a full refund.
