1×8 HDMI Splitter with Independent 4K to 1080p Downscaling
Drive Eight Mixed-Resolution Displays From One 4K60 Source Without Collapsing to the Weakest Screen - 18Gbps 4:4:4, HDCP 2.2, EDID COPY/AUTO
Drives eight mixed-resolution HDMI displays from a single 4K60 source without collapsing the whole array to the weakest screen. The SP-HDMI1X8-18G is a 1×8 HDMI 2.0 distribution splitter that passes the full 18Gbps 4:4:4 signal to all eight outputs and independently downscales 4K to 1080p on any port that needs it, so new 4K panels and legacy 1080p screens run natively off one feed. It ships in a black metal enclosure with an external 12V locking power supply and draws just 6.4W, making it the right choice for signage, hospitality, and corporate distribution where reliable mixed-resolution delivery and install-grade build matter more than 8K bandwidth or matrix switching.
A COPY/AUTO EDID dial resolves the mixed-wall problem at the source: COPY reads the display on HDMI OUT 1 and lets each output serve its connected screen, while AUTO reports the best common EDID so every display accepts the signal. Full HDR10, HDR10+, Dolby Vision, and HLG pass-through keeps signage color and small type clean, and CEC on HDMI OUT 1 lets the anchor display power-sequence with the source. Its strongest differentiator is genuine per-output 4K-to-1080p downscaling with full-chroma 18Gbps HDR pass-through in a metal chassis with a locking multinational supply — the pro-install combination that commodity USB-powered splitters skip and premium distribution amplifiers charge several times more to match.
