2 MBPs one Apple Studio Display.. Is there a confirmed KVM that works?

I've been trying to find a solution to this problem for years at this point. Tried a couple of switches from amazon but kept having to return them because they were under powered. Was so annoyed that I gave up, but now i'm back on the hunt.

Has anyone with the same setup solved this problem? If so please tell me what you used.

Thank you lots.
