Setting Up; Screen Size And Throw Distance - Panasonic PT-LB75VU Operating Instructions Manual

Setting up

Screen size and throw distance

You can adjust the projection size with 1.2× zoom lens. Calculate and define the throw distance as follows.

You can calculate more detailed screen dimensions from the screen diagonal.
The results below are approximate and may differ slightly from the actual measurements.

Minimum distance (LW)
Maximum distance (LT)
Note
For the best quality of the projection image, install a screen where sunlight or room light does not shine directly
z
onto the screen. Close window shades or curtains to block the light and turn off the lamps.
Do not use the projector at a raised or a horizontally tilted position. Doing so may cause malfunction of the
z
projector.
You can tilt the projector body approximately ±30 ° vertically and ±10 °
horizontally.
Overtilting may result in shortening the component's life.
Do not cover the air outlet port and air intake ports or place anything within
z
50 cm (20") of them as this may cause damage or injury.
