The projector includes a 1.2x zoom lens to support a wide range of projection throw-distances. This is useful when presenting in different installation environments.
Note: Above throw-distance is for PT-LW375/LW335 in 16:10 aspect ratio producing a 100-inch image. PT-LB425/LB385/LB355/LB305 requires 3.0 m–3.6 m throw-distance and 4:3 aspect ratio for a 100-inch image.
If on-site conditions call for off-axis projection, simply designate four screen corners and Horizontal & Vertical Corner Keystone Correction performs necessary adjustments for distortion-free image presentation.
* PT-LB305 features vertical keystone correction only.
Barrel and pincushion distortions are easily corrected when projecting onto a curved screen surface such as black- or whiteboards.
* Excluding PT-LB305.
To reduce hassle, the filter can be replaced via the side and the lamp from the top of the projector. There’s no need to remove the unit from its ceiling mount for periodic maintenance.
