1x4 HDMI Splitter 4K@60Hz 4:4:4 - Mirror One Source to Four Displays

In this review the 1x4 HDMI Splitter is evaluated for home theater and gaming use, and the bottom line is simple: it is a practical, no-nonsense solution for duplicating a single HDMI source to multiple displays with reliable 4K@60Hz output. Our review finds the unit especially useful for gamers and small AV setups that need the same signal shown on several screens simultaneously, because it supports 4K@60Hz resolution with stable power and handy EDID controls to resolve compatibility issues.

Key Features

• 4K@60Hz UHD: Supports HDMI 2.0 level video output so compatible sources can deliver crisp 4K@60Hz visuals to connected displays.
• 1 in 4 out distribution: Duplicates one HDMI input to four outputs simultaneously, allowing the same video and audio to play on multiple screens without signal loss.
• EDID management: Built-in EDID switching helps negotiate compatible resolutions and formats between diverse displays and the source device.
• Plug and play setup: Simple physical connections mean most users can install and start using the splitter without driver or software configuration.
• Stable powered operation: The included 5V power adapter ensures continuous operation even with several displays connected.

Who It's For

This splitter is aimed at gamers, small office or retail displays, and home theater enthusiasts who need to mirror one source across multiple screens. It is particularly well suited for users who want to run consoles such as Xbox, PS5, PS4 or a Blu-Ray player to several TVs or monitors at once while preserving high-resolution output.

Those who need independent displays showing different content, a long-distance professional matrix switch, or advanced features like HDCP rewrapping for complex commercial installations should look at multi-input matrix switchers or distribution amplifiers designed for pro AV use.
