If the image does not fill the full width of the DMD, this effectively increases the
throw ratio of the lens. This can be corrected for by applying a Throw ratio factor.
Method one: using the lens charts
For the screen sizes listed below, use the charts on the following pages, to choose
the most suitable lens.
Full width images, including:
2.35:1 (Scope)
1920 x 817 pixels
16:9 = 1.78:1
1920 x 1080 pixels (native resolution)
4:3 images
A Throw ratio factor (TRF) has been applied to the following chart:
4:3 = 1.33:1
1440 x 1080 pixels
TRF = 1.33
Method two: by calculation
See the calculations, on the page immediately following the lens charts.
