3.4.3 Viewport Adjustment
The Viewport menus adjust the image on the DMD™.
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.
