Product Description
G812: Two-Channel Curved-Screen Edge Blending Processor
The G812 is a two-channel curved-screen edge blending processor for image warping, stacking, and projection mapping. It accepts up to 4096×2160@60Hz input with 4:4:4 color and drives two projectors from a single unit, with a built-in 3D demultiplexer that decodes side-by-side and top/bottom 3D into separate left/right eye frames for passive 3D display.
