Overview: This 4K video wall controller (3x3) accepts 1 HDMI input, 1 DVI input and provides 9 HDMI outputs. Its primary function is to split a single HDMI high-definition image into 9 segments and send each segment to one of nine displays (rear projection units, LCD TVs, etc.) to form a single large dynamic screen comprised of 9 HDMI displays. Supported resolutions & compatibility: Each HDMI output supports 1920*1080, 1280x800, 1280x700, 1024x768, 1366x768, 1280x1024. The input is compliant with HDCP 1.4 and HDMI 1.4.

(Note: DVI not support 4k; some input of TV box, Fire sticker may reach 4K/6Ohz, may can't be read.) Flexible splicing modes: The controller offers 13 display configurations — 3x3, 1x2, 1x3, 1x4, 2x2, 2x3, 2x4, 2x1, 3x1, 4x1, 3x2, 4x2 and a 1x1 HDMI splitter mode. Each preset has a dedicated hotkey on the remote and can also be selected via front-panel buttons for fast switching. Vertical (portrait) setup: When using a PC as the input and setting the desktop to portrait orientation you can achieve portrait layouts 1x2, 1x3, 1x4 — note that to enable these portrait arrangements you should select modes 2X1, 3X1 or 4X1 respectively. Control & memory: Control is available through the included IR remote, front panel button control and RS232. Commonly used layouts are accessible directly from the remote. The unit also remembers the last configuration and restores it when powered on again. 180° rotation & edge correction: The 180 degree rotation feature lets you flip the first-row displays 180 degrees to align screens so the thinnest bezels face inward and help reduce a thick center border. The edge mask function fine-tunes bezel compensation and aligns image edges for a smoother multi-screen appearance.
