Installation for a 4:3 ratio screen
SX920
The screen aspect ratio is 4:3 and the projected picture is 4:3
If you have a 4:3-aspect-ratio screen and your measured projection distance was 3.0 m (300 cm), the
closest match in the "Average" column is 298 cm. Looking across this row shows that an 80-inch screen
is required.
Checking the min and max projection distance values in the columns of "Projection distance <D> [cm]"
indicates that the 3.0 m measured projection distance will also fit the 70, 90, and 100-inch screens. The
projector can be adjusted (using the zoom control) to display on these different screen sizes at the
projection distance.
The above numbers are approximate and may be slightly different from the actual measurements. Only the
recommended screen sizes are listed. If your screen size is not in the table above, please contact your dealer
for assistance.
