KVM compatibility checker

Find a KVM that actually works with your setup.

Match your monitors, connections, refresh rate, laptop charging and Mac-specific requirements before you buy. KVMChecker explains what fits, what does not, and where you need to be careful.

Your setup

Start with the requirements that matter most.

Number of monitors

Primary video connection

Target 4K refresh rate

Laptop charging

One host is a Mac using USB-C or Thunderbolt Need USB 3.x peripheral bandwidth Require VRR / adaptive sync Require HDR support Require EDID emulation

KVMChecker uses public manufacturer specifications and deliberately flags uncertain combinations rather than guessing.

Compatibility is more than resolution.

A KVM can advertise “4K” and still be wrong for your desk. KVMChecker looks across the parts of the signal chain that commonly cause failed purchases.

Display capability

Monitor count, connector type and stated refresh-rate limits.

Mac-specific behaviour

USB-C, Thunderbolt and MST limitations can change whether dual displays extend or mirror.

Peripheral requirements

USB bandwidth, EDID, VRR, HDR and laptop power delivery can all eliminate an otherwise plausible match.
