1x4 HDMI Splitter for 4K 30Hz Sources

This powered HDMI splitter takes a single source and sends an identical signal to four displays at the same time. It handles 4K resolution at 30 Hz as well as 1080p and lower formats. The unit includes a 5 V DC power supply for stable operation across all four outputs. Audio passes through with support for multi-channel formats such as DTS-HD and Dolby TrueHD.

Installers needing one source on four screens

The device suits installers who need the same picture on four monitors, projectors or TVs from a single player, console or PC. It does not allow different content on each output, so buyers who want independent images per screen should look elsewhere. It also does not extend a desktop across multiple monitors, only duplicates the input signal. Users requiring 4K at 60 Hz will need a different solution.

4K 30Hz maximum resolution

The highest supported video mode is 3840 x 2160 at 30 Hz with TMDS clock up to 340 MHz and deep colour up to 12 bit. This single specification determines whether the splitter matches the source and display capabilities. If the source outputs 4K at higher refresh rates, the signal will not pass through at its native timing.

Questions about this item

Does the 5 V DC power supply ever need replacing?

The splitter ships with a 5 V DC power supply; if that adapter fails it can be swapped for any 5 V unit with the same barrel connector.

What resolution limit appears first when running four 4K displays continuously?

The chipset caps each output at 3840 x 2160 at 30 Hz, so sustained 4K 30 Hz is the maximum stable signal across all four ports.

How much heat does the unit produce when powered all day?

The aluminium enclosure runs warm but stays within safe limits; no fan is fitted and the 3.2 oz chassis dissipates heat passively.
