(both 4:3 and 16:10 screens)
•
Roll down screens and other screens that are not perfectly flat tend to substantially distort the projection surface
and cannot be used. Use board screens or other flat screens.
Bead-type screens with a high screen gain are not suitable for this projector. Use of a matte screen with a wide
viewing angle and a gain of about 1.0 is recommended.
Interaction between the screen pattern and LCD pixels may result in interference fringes (moiré). This is not a
malfunction. Use a screen that suppresses this phenomenon.
•
The size of the image at the top of the screen changes with focus adjustment. Fine-tune screen position and
angle after adjusting focus the first time.
•
Reset corner fit before starting adjustments.
•
Make sure that the digital zoom value is set to the maximum value (full screen) before starting adjustments.
•
Make sure that the keystone control is set to 0 (no correction) before starting adjustments.
•
It takes about 30 minutes for lamp performance to stabilize and a change in environment may cause subtle
changes in projection location and focus. Make proper adjustments to compensate for changes in focus.
Note:
•
Changes in temperature, humidity and other ambient environmental factors may result in changes in screen
size and location.
•
The minute vibrations and other phenomena that the wall mount unit and the mirror are exposed to will start
to cause changes in projection location a week or so after installation.
1. • Set a screen size that is smaller relative to actual screen size to allow for changes after installation.
• Use the values in the table below to set a vertical and lateral margin.
• Set a margin for each corner to allow for screen distortion.
