Review on 🔁 CKLau 4Kx2K@60Hz 4:4:4 DP Displayport KVM Switch 4 Port - Includes Cables, Audio, and Microphone by Jessie Zdunich

I have a 3440 x 1440 monitor that I was planning to use this KVM with. Unfortunately, some videos just don't work properly. Even with the monitor set to 50Hz (DP 1.2 should easily support this monitor at 90Hz), it sometimes works at best. Most of the time it just flickers a lot before fully shutting down - often times the time misbehaves so badly with feedback from the graphics card on my desktop that it shuts down another monitor as well, not even connected to that KVM. The same goes for the video input from my MacBook: flickering and erratic blackouts. On the downside, the USB switching part works well, but if that's all you need, you can also get a USB switch for half the price. I believe there is a reason for this - the cheapest KVM "DP 1.2" on Revain. However, I strongly suspect that DP 1.1 is actually under the hood here.
