Adjusting the projected image

Adjusting the projection angle

The projector is equipped 4 adjuster feet. These adjusters change the image height and projection angle. To adjust the projector:

Screw the rear adjuster feet to fine-tune the horizontal angle.

To retract the feet, screw the adjuster feet in a reverse direction.

If the projector is not placed on a flat surface or the screen and the projector are not perpendicular to each other, the projected image becomes trapezoidal. To correct this situation, see "Correcting keystone" on page 23 for details.

Auto-adjusting the image

Do not look into the lens while the lamp is on. The strong light from the lamp may cause damage to your eyes.

Be careful when you press the quick-release button as it is close to the exhaust vent where hot air comes from.

In some cases, you may need to optimize the picture quality. To do this, press AUTO on the projector or remote control. Within 3 seconds, the built-in Intelligent Auto Adjustment function will re-adjust the values of Frequency and Clock to provide the best picture quality.

The current source information will be displayed in the corner of the screen for 3 seconds.

This function is only available when PC signal (analog RGB) is selected.

Fine-tuning the image size and clarity

1.Adjust the projected image to the size that you need using the zoom ring.

2.Sharpen the image by rotating the focus ring.
