* All measurements above are approximate and may differ slightly from the actual measurements.

● Calculation methods for screen dimensions

You can calculate more detailed screen dimension from the screen diagonal.

● ● Screen width (SW) and screen height (SH)

$$ \mathrm{SW} (\mathrm{m}) = \mathrm{SD} \left(^ {\prime \prime}\right) \times 0. 0 2 0 3 \mathrm{SH} (\mathrm{m}) = \mathrm{SD} \left(^ {\prime \prime}\right) \times 0. 0 1 5 2 $$

● ● Minimum distance (LW) and maximum distance (LT)

$$ \text { PT - LB80NTU: LW (m) } = 0. 0 2 9 6 \times \text { SD ("') } - 0. 0 3 9 \text { LT (m) } = 0. 0 3 5 8 \times \text { SD ("') } - 0. 0 4 7 $$

$$ \text { PT - LB75NTU: LW (m) } = 0. 0 2 9 2 \times \text { SD ("") } - 0. 0 3 6 \text { LT (m) } = 0. 0 3 5 1 \times \text { SD ("") } - 0. 0 4 4 $$

* The results above are approximate and may differ slightly from the actual measurements.

NOTE:

• See "Screen size and throw distance for 16:9 aspect ratio" on page 47.
• Do not use the projector at a raised or a horizontally tilted position as it may cause malfunction of the projector.
• You can tilt the projector body approximately ± 30^ vertically. Overtilting may result in shortening the component's life.
• For the best quality of the projection image, install a screen where sun light or room light does not shine directly onto the screen. Close window shades or curtains to block the lights.

* All measurements above are approximate and may differ slightly from the actual measurements.

● Calculation methods for screen dimensions

You can calculate more detailed screen dimension from the screen diagonal.

● ● Screen width (SW) and screen height (SH)

$$ \mathrm{SW} (\mathrm{m}) = \mathrm{SD} \left(^ {\prime \prime}\right) \times 0. 0 2 2 1 \mathrm{SH} (\mathrm{m}) = \mathrm{SD} \left(^ {\prime \prime}\right) \times 0. 0 1 2 5 $$

● ● Minimum distance (LW) and maximum distance (LT)

$$ \text { PT - LB80NTU: LW (m) } = 0. 0 3 2 1 \times \text { SD ("") } - 0. 0 4 \text { LT (m) } = 0. 0 3 8 8 \times \text { SD ("") } - 0. 0 6 $$

$$ \text { PT - LB75NTU: LW (m) } = 0. 0 3 1 8 \times \text { SD ("') } - 0. 0 2 2 \text { LT (m) } = 0. 0 3 8 3 \times \text { SD ("') } - 0. 0 4 6 $$

* The results above are approximate and may differ slightly from the actual measurements.
