HDMI 2.1 4-Port Switch - 4K 120Hz / 8K 60Hz for Gaming and Home

In this review of the Cable Matters 48Gbps 4-Port HDMI 2.1 Switch, the bottom line is practical: this is for anyone who needs to connect multiple HDMI sources to a single TV, monitor, or projector and wants HDMI 2.1 bandwidth for high refresh-rate gaming or future-proofing. The reviewer found the combination of 8K@60Hz and 4K@120Hz support, simple installation, and auto-switching useful for small living-room setups and gaming desks where the display has a lone HDMI input. It is especially valuable when you want reliable video bandwidth without running new cables or swapping devices manually.

Key Features

• HDMI 2.1 bandwidth: Supports up to 48Gbps to enable 8K@60Hz and 4K@120Hz signals for compatible consoles and media players.
• Four-input convenience: Lets you connect up to four HDMI sources to a single display, eliminating the need to unplug devices when switching between a console, streaming box, or Blu-ray player.
• Auto-switching and remote: Automatically detects the active input and also provides a lightweight IR remote for manual selection when needed.
• Audio format support: Passes common surround formats such as Dolby Digital and DTS as well as 5.1 and 7.1 streams for home theater compatibility.
• Included high-speed cables: Ships with two HDMI cables rated for 4K@120Hz and 8K@60Hz to preserve signal integrity out of the box.

Who It's For

This switch is aimed at gamers using a PS5 or Xbox Series X/S, media streamers, and anyone with a 4K or 8K display that only has a single HDMI input. The 4-in, 1-out layout and HDMI 2.1 support make it a sensible choice for a compact living room or a monitor setup where high frame rates matter.

It may be less compelling for users who already have multiple HDMI inputs on their display or those who need advanced features not listed here, such as built-in upscaling, Ethernet passthrough, or full HDR metadata management. For professional AV racks, a more feature-rich matrix or hardware with dedicated EDID control might be preferable.

Pros & Cons

Pros

• Supports 8K@60Hz and 4K@120Hz to handle current-generation gaming and high-resolution media.
• Auto-switching plus an IR remote makes everyday use quick and easy without reaching behind the display.
• Includes two high-speed HDMI cables to help ensure proper signal delivery from the start.

Cons

• Limited to a 4-in, 1-out form factor so it does not replace a larger matrix or a switch with advanced EDID options.
