3x3 HDMI Video Wall Controller

The KEHIPI 3x3 HDMI Video Wall Controller splits one HDMI or DVI source across nine 1080P@60Hz outputs for digital signage or multi-screen installations. It accepts a single 4K@30Hz input and drives a 3x3 grid of displays without additional software. The unit is aimed at installers and operators who need a plug-and-play splicing processor.

Input limited to HDMI 1.4 and HDCP 1.4 at 30 Hz

The processor handles one 3840x2160P@30Hz signal and converts it to nine 1920x1080P@60Hz streams with RGB 4:4:4 24-bit colour. Total output resolution remains 4K across the wall. Audio is restricted to PCM 2-channel stereo via auxiliary or optical ports and may be absent when the source runs at 4K@30Hz. Qualified 19-pin shielded HDMI cables are required for reliable sync.

Metal chassis with RS232 control and 180-degree

A rugged enclosure provides nine HDMI outputs, one HDMI input, one DVI input, an optical audio jack and an RS232 port for automation. The 180-degree rotation function lets each screen be flipped without repositioning the panel. Thirteen preset display modes cover common splicing layouts. The 5.1-channel optical output supports external amplifiers for lossless digital sound.

Questions about this item

Which display layout should I pick among the 13 supported modes?

Choose a mode that matches your 3x3 screen grid; each of the 13 presets arranges the nine 1920x1080P@60Hz outputs differently for various aspect ratios and bezel compensation.

What does the 4K input rating mean for my actual 1080P video wall?

The 3840x2160@30Hz input is down-scaled across the nine 1080P@60Hz outputs, giving a combined 4K canvas while each monitor shows a 1080P slice.

How does the HDMI 1.4 interface limit the 3x3 wall in practice?

HDMI 1.4 caps the single input at 3840x2160@30Hz and each of the nine outputs at 1920x1080@60Hz, so 4K@60Hz sources cannot be used.
