Splitter for one source to three displays

The Aomoproing HDMI 2.1 splitter takes a single HDMI input and mirrors it across three outputs. It suits users who need the same 8K or high-refresh 4K image on multiple monitors, projectors or a soundbar. The unit also regenerates the signal at the end of a long cable run.

48 Gbps bandwidth with HDCP 2.3

The chipset delivers 48 Gbps throughput and complies with HDCP 2.3, enabling 8K at 60 Hz, 4K at 120 Hz, 1440p at 144 Hz and 1080p at 240 Hz. RGB 4:4:4, HDR 10+ and Dolby Vision pass through when the display supports them. EDID management and 3D formats are also handled.

Passive operation with no fan noise

The splitter draws power from the HDMI source or an optional USB supply, so it adds no audible fan noise to the setup. Typical draw is low enough for standard HDMI ports. It runs cool in normal indoor use and requires no external cooling or bulky power brick.
