• Leave the projector on for 10 to 15 minutes before adjusting the panel alignment.
• The projected image size should be at least 60 inches (152 cm) during panel alignment.
• If the image contains too much magenta, adjust the red and blue panels.
• If the pattern lines look fuzzy or out of focus, adjust the focus before performing the panel alignment.
