How to determine the recommended screen size for a
given distance
given distance
This method can be used for situations where you have purchased this projector and would
like to know what screen size will fit in your room. The maximum screen size is limited by
the physical space available in your room.

1.
Measure the distance between the projector and where you want to position the
screen. This is the projection distance.

and find the closest match to your measurement in the
average distance from screen column labelled 'Average'. Check that your measured
distance is between the min and max distances listed on either side of the average
distance value.

Using this value, look across that row to the left to find the corresponding screen

On that same row, look across to the right column and make note of the vertical Offset
value. This will determine the final placement of the screen in relation to the
horizontal plane of the projector.
value. This will determine the final placement of the screen in relation to the
horizontal plane of the projector.
For example, if your measured projection distance was 4.5m (4500mm), the closest match
in the Average column is 4682mm. Looking across this row shows that a 3000mm (3m)
screen is required. If you can only obtain imperial sized screens, the listed screen sizes on
either side of the 3m screen are the 9' and 10' screens.

Checking the min and max projection distance values for the these (9' & 10') sizes, indicates
that the 4.5m measured projection distance will fit these screens too. The projector can be
adjusted (using the zoom control) to display on these different screen sizes at that projection
distance. Be aware that these different screens have different vertical offset values.
