*1 The “i” appearing after the resolution indicates an interlaced signal.
*2 The following symbols are used to indicate picture quality.
AA Maximum picture quality can be obtained.
A Signals are converted by the image processing circuit before picture
is projected
B Some loss of data occurs to make projection easier.
*3 Signals with “OK” in the Resizing column can be set using the RESIZING
command in the POSITION menu. (Refer to page 40.)
*4 Signals that are compatible with the FRAME LOCK function. (page 40.)

List of compatible signals
For 16:9 aspect ratios, the following formula can be used to calculate the projection distance.
Projection dimensions calculation methods
If the screen size (diagonal) is SD (m), then the following formula is used to
calculate the projection distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).
