Keystone Correction at Zoomed Lens Position
You can zoom in or out, while keeping an image that was corrected
using Keystone, without again having to make those adjustments.
Improvements in 3D Reform performance allows the projector's adjust-
ment range (horizontal and vertical combinations) to be wider by ap-
proximately 25% in the maximum telephoto position when compared to
initial units shipped.
NOTE: There are some cases when adjusting the zoom position from Tele to
Wide (after performing Keystone correction in Tele) can result in a message
“Range Over ! 3D Reform data has been cleared.”. In this case correction values
for Keystone will return to the factory default setting.
