While not specific to DisplayPort, I've been really impressed with the AV Access 8K KVM Switch [1]. 4K at 120Hz without chroma subsampling was a hard requirement. I use it with macOS Ventura and a Windows 11 desktop. It works nicely in conjunction with a Dell Thunderbolt 3 dock to power an LG OLED and support additional accessories. And it has EDID emulation, which is crucial for maintaining consistent display arrangement. I've tried other DisplayPort KVM switches with mixed success. This is the first one that's worked out of the box.
