I researched a lot for KVMs before. The problem is the video output is hard to get right. What about 120hz+, multi-monitor, how stable the thing is long term. I also thought this is a long solved problem but it isn't. Looking at Ali there isn't a model with too many reviews that can do the above.

At the end of the day this is what I would recommend, it is pricey but everyone swears to it: https://www.store.level1techs.com/products/p/14-kvm-switch-d...
