WRIARICH 2 Port HDMI KVM Switch Dual Monitor 4K 60Hz USB 3.0

Dual-Monitor KVM Switch for Two Computers

This HDMI KVM switch lets one keyboard, one mouse and two monitors control two separate computers. It supports extended or mirrored desktop modes so each system can drive both displays independently. The unit is aimed at users who need to share a dual-screen workstation between a pair of PCs or laptops. Both computers must already be able to output two video signals for the dual-monitor function to work.

HDMI 2.0b Bandwidth and Peripheral Limits

Video passes through an HDMI 2.0b interface with HDCP 2.2 compliance, capping 4K output at 60 Hz while 1080p can reach 144 Hz. The integrated USB 3.0 hub shares two downstream ports between the connected PCs at up to 5 Gbps, and a 3.5 mm audio jack routes sound to headphones or speakers. No external power adapter is required; the switch draws power from the attached systems via the included USB power cable.

Computer Must Support Dual Video Outputs

The decisive requirement is that each connected computer or laptop natively supports two or more simultaneous display outputs. If a system only drives a single screen, the second monitor will remain dark regardless of the switch’s capabilities. Hotkey, push-button and infrared remote switching are all available, and the hotkey function can be disabled if it conflicts with existing shortcuts.
