8K HDMI KVM Switch 4 Computers Sharing 1 Monitor - 8K@60Hz 4K@144Hz

Our review of this 8K HDMI KVM Switch finds it best suited for users who need to control multiple computers from a single workstation without compromising display fidelity. The standout reason to buy is the upgraded video support: it handles up to 8K@60Hz and 4K@144Hz while also switching four USB devices at USB 3.0 speeds, which is rare in one compact box. Setup is plug-and-play for modern systems, and the on-demand EDID function helps preserve desktop layouts when switching, making it a practical choice for mixed workflows.

Key Features

• 4-port HDMI and USB 3.0: Lets one monitor and four USB devices be shared among four computers, saving desk space and cabling.
• High-resolution support: Handles up to 8K@60Hz and 4K@144Hz to keep high-refresh and high-resolution monitors usable across machines.
• EDID on demand: Toggle the EDID function to maintain PC display settings and avoid desktop rearrangement after switching.
• USB 3.0 data transfer: Offers up to 5Gbps for peripherals like cameras and external drives while remaining backward compatible with USB 2.0.
• Dual switching methods: Switch either via the front-panel buttons or the included 1.5 m wired remote for flexible control.
• Cross-platform compatibility: Simple plug-and-play support for Windows, Mac OS, Chrome OS and Linux systems.

Who It's For

This KVM switch is ideal for creative professionals, developers, and small office users who run multiple PCs and need a single high-performance monitor with minimal fuss. If you use high-refresh gaming monitors or work with high-resolution content, the 8K/4K support is the main draw.

It is less suitable for users who expect automatic perfect compatibility in every hardware combination; successful high-resolution switching depends on compatible graphics cards, cables, and monitors, and some customers have reported occasional screen flicker with specific setups. Those who need purely wireless switching or no wired remote should consider alternatives.

Pros & Cons

Pros

• Supports high resolutions up to 8K@60Hz and 4K@144Hz for crisp multi-machine workflows.
• Integrated USB 3.0 hub provides up to 5Gbps for fast peripheral transfers.
• EDID toggle preserves desktop layout when switching between PCs.
• Two switching methods make it flexible for different desk arrangements.

Cons

• Some users report mixed functionality and occasional screen flickering depending on specific hardware and cables.
• High-resolution performance depends on the entire chain (GPU, monitor, cable), which can require troubleshooting.

Specifications

Our Verdict

The 8K HDMI KVM Switch is a solid value for anyone needing to share a high-resolution monitor and multiple USB devices across four systems. Its combination of 8K/4K support, USB 3.0 throughput, and a user-controllable EDID makes it practical for content creators and multi-machine workstations, though buyers should ensure their cables and GPUs support the target resolutions to avoid compatibility hiccups.
