One input to four outputs

This HDMI splitter takes a single source and duplicates it across four displays while preserving signal integrity and resolution. It handles 4K at 30 Hz and remains backward compatible with 1080p and 720p devices. The unit is HDCP compliant and passes CEC signals through to connected screens.

Installations needing identical images on multiple

Suitable for digital signage, conference rooms or classrooms where the same content must appear on several displays simultaneously. Not suited for setups that require independent images on each output or for sources that demand 4K at 60 Hz.

HDMI 1.4 bandwidth of 2.97 Gbps

This bandwidth ceiling limits the maximum resolution to 4K at 30 Hz and prevents higher refresh rates at that resolution. If the source or displays need 4K at 50 Hz or 60 Hz, a splitter with greater bandwidth is required.

Questions about this item

Does the splitter come with the power supply or do I need to buy a 5V 1A adapter separately?

The package includes the 1x4 HDMI splitter and a 5V DC 1A power supply, so no separate adapter is required.

Should I choose this 4K@30Hz model or look for a 60Hz version for my 4K display?

This unit supports 4K x 2K at 30 Hz; if your display needs 4K at 50 or 60 Hz you will need a splitter rated for HDMI 2.0 bandwidth.

What does the 2.97 Gbps bandwidth mean for the picture I actually see on four screens?

The 2.97 Gbps limit carries 4K@30Hz, 1080p at 60 Hz, 720p, 480p, 576p and interlaced formats to all four outputs simultaneously.
