Mirror-Mode HDMI 2.1 Splitter

The llano H402 duplicates a single HDMI source to two displays in mirror mode only. It does not support extended desktop or independent content on each screen. The unit is aimed at users who need identical output on two monitors, TVs or projectors from one console, media player or laptop.

8K@60Hz and 4K@240Hz Headroom

The splitter passes 8K at 60 Hz and 4K at 240 Hz with HDR10, Dolby Vision and HDCP 2.3. Bandwidth runs out above those rates, so higher refresh at 8K or 10K resolutions are not possible. Advanced features such as VRR require support from both connected displays simultaneously.

Aluminium Case with External Power

The aluminium enclosure measures 5.0 in x 8.0 in x 2.5 in and weighs .17 kg. A 5 V 2 A power adapter is required for stable signal amplification. ARC and eARC are not supported, so audio return to a soundbar or receiver must be handled separately.

Questions about this item

Will the H402 work with my older 4K 60 Hz display alongside a new 8K screen?

The splitter mirrors the same signal to both outputs, so both displays receive identical timing; the 8K panel can run at 8K 60 Hz while the 4K panel shows a down-scaled 4K 60 Hz image, provided each screen accepts that resolution.

How can I verify the H402 is passing 8K 60 Hz or 4K 240 Hz correctly after I connect it?

Check the on-screen information menu on each display — it should report 8K at 60 Hz or 4K at 240 Hz with HDR10 or Dolby Vision active, and motion should appear smooth without flicker or frame drops.

What comes in the box with the H402 and what must I supply myself?

The package includes the splitter unit and a 5 V 2 A power adapter; you must provide three HDMI 2.1 cables — one from the source to the input and one from each output to the two displays.
