HDMI Splitter 1 in 4 Out 60Hz - 4K 60Hz Split & Audio Passthrough

In this review the HDMI Splitter 1 in 4 Out 60Hz is evaluated for home theatre and gaming setups that need to mirror one source to multiple displays while preserving high-quality video and surround audio. The standout reason to buy is its reliable 4K@60Hz (4:4:4) support with HDMI 2.0 bandwidth and audio passthrough, which makes it useful for a single console or streaming box feeding a TV and a soundbar simultaneously. It is a straightforward mirroring device rather than a multi-input switch or extender, and works best where identical output on each display is acceptable.

Key Features

• 4K@60Hz support: Delivers up to 4K@60Hz with 4:4:4 chroma for sharp HDR-capable images when paired with HDMI 2.0 cables and compatible displays.
• HDCP 2.3 and bypass: Handles modern content protection so streaming devices and current consoles can display copy-protected content without handshake issues.
• Audio passthrough to soundbars: Each HDMI output can pass Dolby Atmos, DTS 5.1/7.1 and high-resolution digital audio to a connected soundbar or AV receiver.
• Auto downscaling and EDID mode: Automatically adjusts outputs when connected to mixed-resolution displays so a 4K TV can receive 4K while a 1080p set receives 1080p.
• Reasonable cable reach: Supports up to about 15 ft input and 30 ft output for 4K signals, and longer runs for 1080p, making setup flexible in small to medium rooms.

Who It's For

This splitter is aimed at gamers and home theatre users who want to mirror one HDMI source - for example a PS5, PS4, Apple TV 4K, or Elgato capture device - to multiple displays and optionally a soundbar. It is a practical choice for a living room where one console feeds a 4K TV and a second display for a secondary zone.

It is not suitable for users who need extended desktops, different content on each screen, or those wanting to split signals from smartphones, tablets, laptops or MacBooks, since those device classes are not supported. Also avoid it if your soundbar only has ARC/eARC-only ports, as those are not compatible.

Pros & Cons

Pros

• Robust 4K@60Hz 4:4:4 support with HDMI 2.0 18 Gbps bandwidth for clean video output.
• Passes advanced audio formats like Dolby Atmos and DTS 7.1 to connected soundbars or receivers.
• Auto downscaling and EDID management handle mixed 4K and 1080p displays without manual intervention.

Cons

• Mirrors the same content to all outputs and does not support extended or independent displays.
• Incompatible with devices that rely solely on ARC/eARC soundbar ports and with smartphones or tablets.
