Appendix
■Relationship between Projection Distances and Projection Screen Sizes
Notes |
Note: There is a 7% drop (for ceiling mount) using the anamorphic lens. Calculate 7% of the through distance.
•The relationship between the projection distances and projection screen sizes differs depending on the lens unit (optional) you are using.
•The projection distance and projection screen sizes listed here are only for a guide. Use them as reference when setting the projector.
