3x1 HDMI 2.1 Switch 4K 120Hz - 8K HDMI Selector for Consoles

Our review of the 3x1 HDMI 2.1 Switch sums it up simply: this compact aluminum alloy switch is for anyone who needs to connect multiple HDMI sources to a single display without swapping cables. It earns that recommendation because it supports up-to-date HDMI 2.1 bandwidth and modern resolutions, making it especially useful for gamers and media streamers who want 4K@120Hz or 8K@60Hz performance. Setup is plug-and-play, and the metal housing feels sturdy, so the unit works well as a practical, space-saving device for a living room or small home office.

Key Features

• Three inputs, one output: Lets users connect three HDMI sources and switch between them to reduce cable clutter and simplify device management.
• HDMI 2.1 bandwidth: Supports up to 48Gbps so it can handle 8K@60Hz, 4K@120Hz and 1080P@240Hz signals for smooth, high-frame-rate video.
• Aluminum alloy build: The metal chassis improves durability and feels more robust than plastic alternatives in everyday use.
• Plug and play: No external power required when input sources provide power through the HDMI ports, simplifying installation.
• Simple switching: A front push button allows manual selection of the active input without menus or remotes.

Who It's For

This switch is aimed at gamers running current-generation consoles who want to preserve high refresh rates and resolutions when switching between a console, streaming stick and a media player. It also suits home theater users who need a tidy way to manage multiple HDMI devices into a single TV or projector.

Users who rely on very long HDMI runs beyond about 3m/9.8ft for 8K signals, or those who need advanced routed audio features and remote control integration, should consider alternatives that include powered extenders or matrix switching. Casual users with only one or two devices may not need the extra HDMI port or the 2.1 bandwidth benefits.
