3.3.1 Automatically Adjusting the Lamp Position Using LampLOC
™
Performing Automatic LampLOC
™
activates a set of motors and sensors in the projector to precisely position
the lamp for optimized performance and brightness. Once aligned, this LampLOC
™
setting can be considered
fairly stable for the life of the lamp.
1. Navigate to the
Advanced Setup: LampLOC Setup
2. Touch the
Do Auto
button.
3.
Let a few minutes pass to allow the LampLOC
™
mechanism to establish the best lamp position and
optimize the light output. You will see 100% displayed on the screen when the operation is complete.
You can improve on-screen uniformity after running LampLOC
™
by manually adjusting the z-axis motor.
However, brightness efficiency will be decreased by a very small amount when this is done.
