HDMI KVM Switch 2 Monitors 4 Computers - Dual 4K60Hz Switching

Our review of this HDMI KVM Switch 2 Monitors 4 Computers finds it most useful for small offices, multimedia classrooms, and power users who need to share two displays and multiple USB devices across four PCs. The single biggest reason to buy is the reliable dual-monitor sharing with 4K@60Hz support and EDID lock, which preserves each computer's resolution and window arrangement when switching. Setup is plug-and-play and switching is straightforward via the included remote or front-panel buttons, making it a practical choice where multiple systems must be accessed without rearranging displays.

Key Features

• Dual monitor KVM: Allows four computers to share two HDMI displays so users can view the same or different content on each screen for increased productivity.
• EDID lock screen: Emulates and stores monitor EDID so resolutions and refresh rates remain consistent and windows do not move when switching between computers.
• 4K@60Hz support: Delivers ultra-high definition output when source, cables, and displays support 4K@60Hz, with backward compatibility to lower resolutions.
• Two switching modes: Offers remote control switching for convenience or direct front-panel button switching for quick local access without hotkey setup.
• Four USB 3.0 ports: Provides high-speed device sharing at up to 5 Gbps for keyboards, mice, printers, and other peripherals while remaining backward compatible with USB 2.0 devices.

Who It's For

This KVM is aimed at professionals and educators who need to manage four computers from a single dual-monitor workstation, especially where maintaining each machine's display settings matters. IT managers running demos, control rooms, and mixed OS environments will appreciate the plug-and-play compatibility across Windows, Mac OS, Linux, and Unix.

It is less suitable for users with single-monitor setups, or those who rely on hotkey switching since hotkeys are not supported. Also, each computer must provide two HDMI outputs to use both displays, so laptops or systems with only one HDMI port may require adapters or alternative arrangements.

Pros & Cons

Pros

• Supports dual-monitor operation for four computers, saving desk space and simplifying workstation workflows.
• EDID emulation keeps display resolutions and window layouts intact across switches, reducing interruptions.
• High-speed USB 3.0 ports let you share fast peripherals and storage between systems.
• Remote and button switching provide flexible control options without drivers.

Cons

• Does not support hotkey switching, which may slow workflow for users who prefer keyboard shortcuts.
• Each computer requires two HDMI outputs to use dual monitors, which could require extra adapters for some laptops.
