VigilLink GeoBox M802ex Two-channel Edge Blending And Projection-mapping Processor
The M802ex extends VigilLink's GeoBox mapping line to two channels, pairing edge blending with true projection mapping - warping a 4K/2K input onto irregular or non-planar surfaces such as columns, domes, and building facades rather than just correcting for a flat screen. Each of its two processing modules takes two HDMI, one DisplayPort, and one VGA input and outputs up to 2048x1080/60Hz, so a single chassis can drive and align two projectors from one rack position.
A 10-bit engine holds geometry alignment to up to 120x68 warp control points per channel while keeping system latency to a single 33ms frame pair, and independent R/G/B gamma correction on the blend zones keeps color consistent where projector images overlap. Control is available from the front keypad, an IR remote, RS-232, USB, or Ethernet/web page, and multiple M800EX units cascade together for installs that need more than two channels.
