Since the info is pretty scarce about exactly what KVMs support G-Sync and Freesync, hopefully this thread will help a bit.

My guess is that any KVM that supports 4k60 will work with G-Sync and Freesync but that is not confirmed.

Level1techs.com has a couple:

4-port single monitor
https://store.level1techs.com/products/kvm-switch-single-monitor-model - $345

4-port dual monitor
https://store.level1techs.com/products/kvm-switch-dual-monitor-model - $565

Blackbox has at least 1:

2-port dual monitor - Though the specs don't specify it, I sent them an email and was told that per the engineers it will do 144Hz at 1080p and 1440p and is compatible with G-Sync and Freesync

Startech:
2-port single monitor - per the nVidia forums here: https://forums.geforce.com/default/topic/1060207/pc-components/kvm-switch-displayport-g-sync/
https://www.startech.com/Server-Man...rt-displayport-kvm-switch-4k-60hz~SV231DPU34K

2-port dual monitor - waiting to receive this one to verify although a response from Startech on Amazon says it will support up to 165Hz at 1440p and below:
Edit: Just got it hooked up and it works fine with G-Sync.

One thing to note:
AMD can do Freesync over HDMI or Displayport.
Nvidia can only do G-Sync over Displayport.

Is anybody on top of this?

It's it reasonable to expect in 2022 that all 4k60 kvms support freesync?
