4K60 1×2 HDMI Splitter with Auto Downscaling & EDID Control
No Blank Second Screen on Mixed-Resolution Displays - 18Gbps, HDCP 2.3, HDR10+/Dolby Vision Pass-Through
Sends one 4K60 HDR source to two displays at once and keeps the lower-resolution screen live instead of blanking it. The SP-HDMI1X2-18G is a passive 1×2 HDMI splitter in a black metal enclosure, powered by a single 5V/1A multinational supply and drawing 1.41W, sized to stack behind a display or tuck into a small credenza rack. It is the right choice for media rooms and huddle spaces where reliable HDCP, HDR pass-through and a second screen that never goes dark matter more than audio de-embedding or 8K headroom.
Full 18Gbps HDMI 2.0b bandwidth carries 4K60 4:4:4 with HDR, HDR10, HDR10+, Dolby Vision and HLG intact, while HDCP 2.3 and 1.4 compliance clears protected sources to both outputs. Per-output auto downscaling matches each display's capability independently, so a 4K panel and a 1080p projector run from the same source without a separate scaler, and front-panel EDID control adds STD (forced 1080p) and TV (copy OUT1) modes for stubborn sinks. The differentiator is the combination — full-bandwidth HDR pass-through with automatic per-output downscaling in a supported metal-body unit, not the feature-max audio-breakout tier.
