Review on 🔁 CKL DisplayPort KVM Switch 2 Port with Cables 4K@60Hz 4:4:4 321DP" - Optimized DisplayPort KVM Switch 2 Port with Cables | 4K@60Hz & 4:4:4 | CKL 321DP by Hayden Hart

I think the best thing that can be said about this product is that it works and it's good value, but it has so many problems. The biggest problem is that very often when switching between computers, it's as if those computers see your mouse or keyboard for the first time and each time you switch there and back, they reinstall all of the software for each of those items. I read that some other people also had this problem before I bought this and I thought maybe it's just a bad device, but that seems to be the problem. It's surprisingly difficult to find a good KVM switch that does the job.
