About this guide
DVI KVM shopping starts with the display connection: single-link DVI, dual-link DVI and dual-monitor DVI are different requirements. Check every computer’s output, whether an adapter is active or passive, the monitor resolution and the USB peripherals you need to share before choosing a two-port switch.

Buying tips
- Match the switch’s maximum resolution and link type to the monitor before ordering.
- Use direct DVI connections when possible; conversion adapters can complicate EDID detection.
- Count every required cable for dual-monitor hardware before setting the budget.
