This Fjgear 8-in-1 Quad Multi-Viewer HDMI Splitter lets you connect up to four HDMI sources and view them simultaneously on a single 1080p or 4K display. It supports HDMI 2.0 with HDCP 2.2, handling 4K @ 30 Hz video and full‐range audio without lag. The built‐in scaling engine automatically adjusts each input to fit the screen layout, so you can switch between picture‐in‐picture, side‐by‐side, or full‐screen modes with the remote. Plug‐and‐play design means you just connect power and cables, no drivers required, making it easy to set up in conference rooms or home theaters.
