8K HDMI Switch 4 in 1 Out - 4K@120Hz HDMI 2.1 Switcher

In this review of the 8K HDMI Switch 4 in 1 Out, the bottom line is simple: this unit is for gamers and media enthusiasts who need to connect up to four HDMI sources to a single display while preserving the highest available resolutions and frame rates. The single biggest reason to buy is its support for 8K@60Hz and 4K@120Hz along with HDMI 2.1 features like VRR and ALLM, which keeps gameplay smooth without swapping cables or juggling TV inputs.

Key Features

• 4 In 1 Out: Lets the user connect up to four HDMI devices to one display so switching between consoles and streamers is fast and cable-free.
• High-resolution support: Handles up to 8K@60Hz and 4K@120Hz to preserve detail and high refresh rates for next-gen gaming and 8K media playback.
• HDMI 2.1 technologies: Supports HDR10+, Dolby Vision, Dolby Atmos, VRR and ALLM to maintain advanced picture and audio features across devices.
• Multiple switching modes: Offers remote control, manual button, and automatic last-active input switching for flexible day-to-day use.
• Stable powered operation: Includes a power cord to reduce flicker and keep high-bandwidth signals stable under demanding formats.

Who It's For

This switch is best for console owners using PS5 or Xbox, PC gamers with high refresh displays, and anyone with a mix of 4K/8K sources who wants the convenience of a single display input. It particularly fits setups that require low latency and features like ALLM and VRR for responsive gaming.

People who need simultaneous outputs to multiple displays or very long HDMI cable runs should look elsewhere; optimal use requires HDMI 2.1-certified cables and cable lengths under about 3 meters for top-end 8K or 4K@120Hz performance.

Pros & Cons

Pros

Cons

• Does not output to multiple displays at once, so it is not suitable for multi-screen setups.
• Top performance depends on using HDMI 2.1-certified cables under 3 m, which may require cable upgrades.
