HDMI KVM Switch 4 Computers 1 Monitor - Seamless 4K@60Hz Switching

In this review of the HDMI KVM Switch 4 Computers 1 Monitor from ATLAHET, the bottom line is simple: it is a practical, budget-friendly solution for anyone who needs to control multiple PCs from a single display and set of USB peripherals. The unit's biggest asset is straightforward one-touch switching between four computers while sharing four USB 3.0 devices, making it ideal for small offices, multi-OS workstations, or content creators who juggle several machines. Setup is plug-and-play and the included remote and IR cable add convenient switching without reaching behind desks.

Key Features

• 4-port HDMI switching: Lets four computers share a single HDMI monitor so the user can control multiple systems without extra displays.
• USB 3.0 peripheral sharing: Four USB 3.0 ports allow sharing of keyboard, mouse, printers or scanners with up to 5 Gbps transfer speeds for fast file access.
• High-resolution video: Supports up to 4K@60Hz and 2K@120Hz over HDMI 2.0 for clear, high-refresh visuals when the connected GPU and display support those modes.
• Two switching modes: Front panel buttons and an infrared remote provide quick, one-touch switching for different desk setups and user preferences.
• Stable powered operation: An included 12V 1A external power supply ensures reliable performance when multiple USB devices draw power.
• Broad compatibility: Plug-and-play support across Windows, macOS, Linux and Unix reduces driver hassles and works with many HDMI sources like laptops and set-top boxes.

Who It's For

This KVM is best for small office users, developers, IT technicians, and content creators who regularly operate more than one desktop or laptop and want to reduce desk clutter. It fits well where a single high-resolution monitor is used for multiple systems and where sharing USB accessories is important.

Users who require cutting-edge 8K video, multi-monitor KVM switching, or built-in KVM over network features should look elsewhere; this unit focuses on practical 4K switching and local USB sharing rather than advanced enterprise capabilities.

Pros & Cons

Pros

• Simple plug-and-play setup makes multi-computer control easy without driver installation.
• USB 3.0 ports provide fast peripheral throughput and backward compatibility with older devices.
• Includes remote control and IR cable for convenient switching and an external power supply for stability.
• Supports 4K@60Hz and 2K@120Hz for smooth, high-resolution output when hardware allows.

Cons

• 4K@60Hz depends on both the computer GPU and display supporting that resolution and a good HDMI 2.0 cable; not a 8K solution.
• Designed for single-monitor setups only, so users needing multi-monitor KVM functionality will need a different model.

Frequently Asked Questions

Does it support 4K@60Hz?
Yes, the switch supports 4K@60Hz via HDMI 2.0 but both the computer GPU and display must also support that resolution and a quality HDMI 2.0 cable is recommended.

Can I use high-power USB devices?
The unit includes a 12V 1A external power supply to maintain stable operation with multiple USB devices, but extremely high-draw devices may still need their own power.

Is driver installation required?
No, the KVM switch is plug-and-play across major operating systems and does not require additional drivers for basic switching and USB peripheral sharing.
