4K@60Hz HDMI KVM Switch 4 Computers to 1 Monitor - USB3.0 Share

In this review of the 4K@60Hz HDMI KVM Switch, the bottom line is simple: this unit targets professionals and power users who need to control up to four PCs with one keyboard, mouse and single 4K monitor while sharing high-speed USB 3.0 peripherals and multi-channel audio. The reviewer found the KVM delivers on video clarity and flexible audio routing, with useful switching options including a desktop button and an IR remote, making it a practical choice where 4K@60Hz and USB 3.0 device sharing are priorities.

Key Features

• 4K@60Hz HDMI support: Provides crisp 4K@60Hz RGB4:4:4 output so a single monitor can show high-resolution content without obvious color subsampling loss.
• USB 3.0 device sharing: Four USB 3.0 ports allow sharing wired or wireless keyboards, mice and high-speed storage with up to 5Gbps transfers for fast file access between hosts.
• Multi-format audio extractor: Built-in SPDIF optical, L/R stereo and mic ports let you route digital or analog sound to an amp or recording device without relying on the monitor.
• Flexible switching: Switch between machines via the front button, supplied IR remote or remote switch, which helps keep the unit out of sight while remaining accessible.
• Wide video compatibility: Accepts multiple refresh and resolution formats including 1080p@144Hz and 2K@144Hz, plus HDR and Dolby Vision passthrough for compatible sources.

Who It's For

This KVM is best for content creators, IT administrators and multitaskers who need to operate four desktop systems from one workstation while keeping fast external drives and USB devices available to all hosts. The combination of HDMI2.0 video support and USB 3.0 ports makes it suitable where both visual fidelity and high throughput are required.

It is less appropriate for users who need hotkey-only switching (the unit does not support hotkey switching) or for those with very long HDMI runs; the manufacturer recommends standard HDMI 2.0 cables under 3m for reliable 4K@60Hz performance.

Pros & Cons

Pros

• High-quality 4K@60Hz RGB4:4:4 support preserves color and detail for demanding displays.
• USB 3.0 ports provide up to 5Gbps speed for shared external drives and fast peripherals.
• Audio extraction with SPDIF, L/R and mic ports offers flexible routing to amps or recorders.
• Multiple switching methods including IR remote keep the device convenient and tidy on a desk.

Cons

• No hotkey switching option, so users must rely on the button, IR remote or remote switch for changing sources.
• Requires HDMI 2.0 cables under 3m for guaranteed 4K@60Hz performance, which may mean replacing older cables.

Frequently Asked Questions

Can the unit pass HDR and Dolby Vision?
Yes. The KVM supports 8bit HDR and Dolby Vision passthrough for compatible sources and displays.

Will my USB 2.0 devices work on the USB 3.0 ports?
Yes. The USB 3.0 ports are backward compatible with USB 2.0 and 1.1 devices but will operate at their native lower speeds.

Can audio be extracted independently from the HDMI output?
Yes. The SPDIF optical and L/R stereo outputs allow audio to be routed separately to speakers or an amplifier without using the monitor.
