HDMI Extender Splitter 4K 60Hz 1 in 4 Out - Mirror to Four Displays

Our review of the HDMI Extender Splitter 4K 60Hz 1 in 4 Out finds it ideal for small installations that need to mirror a single source across multiple screens. The unit's single-Cat5e/6 distribution up to 196ft per receiver and built-in power over cable make it a simple way to extend a high-resolution HDMI feed without running long HDMI runs, and the local HDMI loop-out plus 4K to 1080P downscale option is the single biggest reason installers and AV hobbyists will choose it.

Key Features

• 1 to 4 mirroring: Sends a single 4K@60Hz HDMI signal to four displays so multiple rooms or zones can show identical content simultaneously.
• Extended range: Each receiver can be placed up to 196ft away using a single Cat5e/6 cable, reducing the need for long HDMI cables.
• Local HDMI loop-out: Lets you monitor the source at the transmitter location while the same signal is distributed to remote displays.
• 4K downscale to 1080P: Receivers can downscale 4K to 1080P so mixed-resolution displays can be used in the same setup without image compatibility issues.
• Audio extraction: Optical and 3.5mm analog outputs allow connection of external speakers or audio systems for each receiver or the transmitter.
• PoC and EDID DIP switches: Power over Cable simplifies wiring by powering receivers from the transmitter and EDID switches improve format compatibility with different source and display combinations.

Who It's For

This product is best for installers, small businesses, houses of worship, and home theater enthusiasts who need to mirror one HDMI source to several displays without complex network equipment. It suits setups where identical content is required across multiple screens and where runs of Cat5e/6 are already practical to install.

Those who need independent content per display, HDMI matrix switching, or longer-term heavy-duty continuous operation in mission-critical environments should consider a matrix switcher or industrial-grade distribution system, since this splitter is designed specifically for mirrored output and consumer-to-light-pro AV use.

Pros & Cons

Pros

• Distributes a clean 4K@60Hz signal to four mirrored outputs over single Cat5e/6 runs, simplifying multi-screen setups.
• Local HDMI loop-out and downscaling provide flexibility for mixed-resolution displays and local monitoring.
• Audio extraction via optical and 3.5mm lets you route sound to external devices without extra converters.
• PoC reduces the number of power adapters needed and EDID DIP switches help resolve handshake issues.

Cons

• Mirrored output only, so it cannot deliver independent sources to each display.
• Some users report mixed long-term durability, so continuous heavy use may require monitoring or redundancy planning.

Our Verdict

The HDMI Extender Splitter 4K 60Hz 1 in 4 Out is a practical, cost-effective choice for anyone needing to mirror one high-resolution source to multiple screens with minimal cabling. Its downscale and audio extraction features add useful flexibility, and PoC simplifies installation. For mirrored-display applications it offers solid value, though users expecting independent feeds or heavy 24/7 industrial duty should evaluate higher-end alternatives.

Frequently Asked Questions

Can the unit power the receivers over the Cat cable?
Yes, the transmitter supports PoC so receivers receive power via the connected Cat5e/6 cable and only the transmitter needs a power adapter.

Will it work with mixed 4K and 1080P displays?
Yes, receivers can downscale 4K to 1080P so mixed-resolution monitors can be used together in the same installation.

Does it send different content to each display?
No, this splitter mirrors the same HDMI source to all four outputs and does not provide independent matrix switching.
