Introduction

Display a single 4K HDMI signal to four separate TVs/monitors with the AC7831 4K HDMI Splitter. Ideal for use of digital signage in a store, waiting room, bar or office. The maximum resolution is 3840x2160 (4K) @30Hz and 1080p@120Hz. The AC7831 supports EDID, Chroma sampling 4:4:4, HDCP 1.4 and comes with an external power adapter.

Split one 4K video source to multiple TVs
The AC7831 HDMI splitter is the perfect solution for displaying digital signage on four separate TVs or monitors with HDMI. The AC7831 is equipped with one HDMI input and four HDMI outputs. The splitter divides the video source up to 4 target screens with a maximum distance of 5 meters without compromising video quality. The AC7831 is equipped with status LEDs that show which screens are connected.

EDID support
The EDID copy function, also known as Extended Display Identification, ensures the resolution communication between the source and output devices. The AC7831 will copy by default the resolution of the TV/monitor connected to HDMI output 1. If this is a 4K monitor, the output will be 4K for all monitors. If a monitor doesn’t support 4K, there won’t be any image on this particular monitor. If the monitor connected to HDMI output 1 is a 1080p monitor, and 4K TVs/monitors are connected, these will display images with a resolution of 1080p.
