Hey wise redditors, I've been struggling to find a solution for my KVM setup so I'm gonna ask for help here:

I’m looking for a KVM that supports a dual-monitor desk shared between a MacBook Air M4 for work and a gaming PC. The monitors are an ASUS PG27UCDM and an ASUS XG27ACDNG, and I need the solution to support 4K at 120Hz ( 1 display is 4k, and the other is QHD, but both are 120hz). On the PC side, I’m currently passing the GPU signal through the motherboard and using Thunderbolt, so I can have a single cable carrying display + data into the KVM. Ideally, I’d love the whole setup to be as close to “one USB-C cable per machine” as possible, but from what I understand that may not be realistic on the Mac side without using something like DisplayLink, which I’d rather avoid.

The main things I care about are:

• One cable from each computer into the switching setup, if realistically possible
• Dual-monitor switching between the MacBook Air M4 and the gaming PC
• 4K 120Hz support
• Keyboard, mouse, and ideally audio switching too
• Price wise I'm flexible but I don't wanna pay over 1k for a KVM...

I’ve heard good things about Level1Techs KVMs, but I’m not sure I can achieve exactly want I need/want...

What I need exist or I'm just dreaming?
