Cautions on 3D irregular color correction adjustment
The following measurement and adjustment must be carried out:
• In a dark room (take care for stray light)
• Using diffuse reflection type (mat type) screen in the uniform conditions.
Settings of the projector must be carried out in the following conditions:
• Do not save power (to keep the lamp to the stable condition during measurement)
• Automatic search cancel (to fix INPUT1)
• INPUT1 RGB mode (cancel the component mode of INPUT 1, just in case)
(1) System setting (“setting” - “system setting”)
