1x8 HDMI Splitter 3840x2160

The LUOM HW-HD4K takes a single HDMI source and duplicates it across eight displays simultaneously. It supports video resolutions up to 3840 x 2160 and handles 3D content alongside standard formats such as 1080p and 1440p. An included power adapter drives the internal amplification for longer cable runs. The unit is suited for installers who need identical mirrored output on multiple screens.

Installers needing eight identical displays

This splitter suits control rooms, digital signage, classrooms and home-theatre matrices where every screen must show the same image. It does not suit users who want independent content on each output or who require switching between different sources. Buyers needing only two or four outputs should consider a smaller unit to avoid unused ports.

Check source resolution and cable lengths

Verify that your source device can output at the desired resolution up to 3840 x 2160 and that it complies with HDCP requirements. Confirm that the total HDMI cable distances from the splitter to each display fall within the amplifier's reach for a stable signal. Ensure the included power adapter matches your local mains voltage before connecting the unit.

Questions about this item

What HDMI source do I need to feed the HW-HD4K splitter's single input?

Any device with a standard HDMI output — PC, cable box, PS3, PS4, Xbox 360, Xbox One, Wii U, Blu-ray player, DVR, Chromecast or Fire TV — will drive the 1x HDMI female input.

Will my 1080p monitors work with the eight HDMI outputs that support up to 3840 x 2160?

Yes, the splitter duplicates the input signal to all eight outputs, so 1080p, 720p, 480p and other listed resolutions display identically on each connected screen.

How can I verify the HW-HD4K is passing both 4K video and 7.1 audio correctly after setup?

Play a 4K test pattern with multi-channel audio from the source; all eight displays should show the same image and each audio system should decode LPCM, Dolby TrueHD or DTS-HD Master Audio.
