2. Floating mechanism
The floating mechanism corrects image distortion between 40" and 50". At time of shipment, it is optimized for
a diagonal of 40" (including 2.0% underscan), but the floating mechanism should be adjusted if the projection
size is different and image distortion becomes prominent. Recommended values for different projection sizes
are given below, but adjustments should be made such that image distortion is minimized.
