Best KVM Switches for Dual Monitors (2026)
The DMT audience’s dream hardware: one hotkey switches your entire dual-monitor desk between two computers.
What to look for
- Dual video outputs: two HDMI or DisplayPort outs — non-negotiable for a dual-monitor desk.
- Resolution/refresh support: match your monitors (4K@60, 1440p@144, etc.). Cheap KVMs cap out at 4K@30.
- USB switching: enough ports for keyboard, mouse, and extras; USB 3.0 if you switch external drives.
- EDID emulation: keeps the “ghost” of your monitors connected so windows don’t rearrange on every switch.
- Switching method: hotkey, front button, or remote — hotkey people will feel at home.

DMT + KVM is a power combo
Pro tips
- DMT runs per-computer, so install it on both machines — your hotkeys follow you across the switch.
- Use DMT’s Swap Screen hotkeys for window layout and the KVM hotkey for machine switching: two layers of keyboard control, zero reaching.
Frequently Asked Questions
What does a KVM switch do?
It lets one set of keyboard, video (monitors), and mouse control two or more computers. Press a hotkey or button and your whole dual-monitor desk switches from work laptop to gaming PC instantly.
Do I need a dual-monitor KVM or single?
If both monitors should switch computers together, you need a KVM with two video outputs (dual-monitor KVM). Single-monitor KVMs leave the second screen on one machine.
Will a KVM add input lag for gaming?
A good KVM adds negligible latency. Look for models with USB passthrough for gaming peripherals and EDID emulation so monitors don’t resync on every switch.
