What is the DMD?

DMD stands for Digital Micromirror Device. It is Texas Instrument’s name for their patented chip that produces the pictures in a DLP™ (Digital Light Pro- cessing) system.

The DMD chip is about the size of a postal stamp and contains, in the case of Margay, 1280 by 720 pix- els.

What is Viewport?

The Viewport menu adjust the number of pixels actually used on the DMD. You can’t increase this number, naturally, but you can reduce it.

•DMD Resolution shows the resolution of the DMD chip. This has nothing to do with the reso- lution of the source picture.

•Viewport shows the number of DMD pixels being used.
