Alxum 2 Port HDMI KVM Switch with Audio and Mic - Dual 4K@60Hz

In this review the Alxum 2 Port HDMI KVM Switch is evaluated as a solution for users who need to control two desktop PCs with two monitors while sharing peripherals. The single biggest reason to consider it is its ability to run two displays at up to 4K@60Hz per monitor while providing fast USB 3.0 peripheral access, which makes it especially useful for video editors, streamers, and multitasking professionals who need a neat dual-computer workstation.

Key Features

• Dual-monitor switching: Two HDMI inputs and two HDMI outputs let a user switch control between two desktop PCs without reconnecting displays, saving time and desk clutter.
• High-resolution support: Native support for 4K@60Hz output ensures sharp video and smooth motion when using HDMI 2.0 or higher cables up to the recommended length.
• USB 3.0 peripheral hub: Three USB Type-A ports with up to 5Gbps transfer speed allow shared mice, keyboards and external storage with fast data throughput.
• Audio and microphone support: A 3.5mm combo jack delivers audio and microphone connectivity for conferencing, streaming, or content creation without extra adapters.
• Dual switching modes: Hardware buttons and the included desktop controller/remote provide instant, flexible switching between the two connected computers.
• Compact design: Small footprint and tuck-away form factor keep workspaces organized while maintaining full connectivity.

Who It's For

The Alxum KVM switch is aimed at creators and professionals who run two desktop PCs and need to share two monitors and USB peripherals with minimal hassle. It suits video editors, streamers and educators who benefit most from the dual-monitor 4K capability and the integrated audio/mic port for live sessions.

It is not recommended for laptop users who want to drive both displays simultaneously or anyone relying on DisplayPort-only systems, since the product does not support DP interfaces or DP-to-HDMI passive conversion. Buyers who need long-distance 4K runs beyond the specified cable length should look elsewhere.
