Dual-monitor KVM for two PCs

This HDMI KVM switch lets you control two computers with one keyboard, one mouse and two shared monitors. Each system connects through two HDMI cables and a USB-B link so video and USB signals stay in sync. The unit supports extended desktop or mirrored output across both screens. No external power supply is needed for basic operation.

Driver-free switching with four USB 2.0 ports

Front-panel buttons and a wired remote give instant PC selection without software installation. Four USB 2.0 ports accept wired or wireless keyboards, mice, printers or storage drives. The switch works with Windows, Linux and macOS out of the box. Note that high-definition webcams and some MacBook Pro models are not recommended for use with this device.

Upgrades single-monitor or USB-only setups

If you currently swap cables or run a single-screen KVM, this unit adds a second display and a built-in four-port hub in one box. The jump is worth it when you need simultaneous dual-monitor workflows across two computers at up to 3840x2160 at 30 Hz or 1440p at 60 Hz. Buyers who need higher refresh rates at 4K or more than two computer ports should look elsewhere.
