For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 16:9
minimum
L (m) = (diagonal screen size in inches) × 0.0330 – 0.0233
maximum
L (m) = (diagonal screen size in inches) × 0.0397 – 0.0237
Aspect ratio 4:3
minimum
L (m) = (diagonal screen size in inches) × 0.0303 – 0.0233
maximum
L (m) = (diagonal screen size in inches) × 0.0364 – 0.0237
NOTE:
Distances calculated with the above equations will include a slight error.
Installable angle
Install the projector at an angle within the range shown below.
• Horizontal direction
The projector may be installed at a horizontal
angle of 15°.

List of compatible signals
The signals that can be input to this projector are shown in the table below. Horizontal scanning frequencies of 15 kHz to 91 kHz, vertical scanning frequencies of 24 Hz to 85 Hz, and a dot clock of
162 MHz maximum can be input.
NOTE:
The native resolution of this projector is 1,024 × 768 pixels. If the display resolution of the input signal is different from the
native resolution, image compression or expansion will be used to convert the input signal to a level within the native resolution.
