projector has a fixed
resolution
, which affects the
aspect ratio
of the projected image.
A Digital Micromirror Device™ (DMD™) consists of moving microscopic mirrors. Each mirror, which acts as a pixel, is suspended between
two posts by a thin torsion hinge. It can be tilted to produce either a bright or dark pixel.
EDID (Extended Display Identification Data)
Information stored in the projector that can be read by the source.
EDID is used on the HDMI, DVI and VGA inputs, allowing the source to automatically configure to the optimum display settings.
