BenQ cp270 Projector User Manual


 
Operation 27
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 28 for details.
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 adjuster button as it is close to the exhaust vent where hot
air comes from.
Auto-adjusting the image
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 upper left corner of the screen for 3 seconds.
The screen will be blank while AUTO is
functioning.
This function is only available when a 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. Then sharpen the image by rotating the focus
ring.
