Zoom menu entries:
• Image Resolution is the resolution of the source picture.
• This Unit is the number of pixels this unit is using of all the incoming pixels.
Viewport Window Top & Left/Viewport Window Bottom & Right: The controls in the
Viewport menus adjust the number of pixels actually used on the DMD™. Use them to
mask the edges of the display area (to eliminate “snow” or edge noise, for example). You
cannot increase these values beyond 1920 pixels horizontal or 1080 pixels vertical (817
pixels vertical on the CineWall CW-95HD), but you can decrease them.
What is the DMD? DMD stands for Digital Micromirror Device. It is a Texas Instruments
trademark for their patented chip that produces the pictures in a Digital Light Processing
(DLP™) system. The DMD chip is about the size of a postage stamp and contains, in the
case of the VW-100HD, 1920 by 1080 pixels.
