Notes

•Automatic adjustment may not be performed properly for signals other than those computers’ signals with which the projector is compatible.

•The horizontal position, vertical position, sampling phase and sampling frequency can also be adjusted from the menu screen 46.

*Sampling frequency

Analog RGB signals input from the computer are converted into digital signals inside the projector. The sampling frequency is the number of times per second the analog signals are converted into digital signals. In order to capture (sample) each individual dot of the computer’s signals, the sampling frequency must be adjusted to match the computer’s dot clock frequency. If this adjustment is off, details of the image details may be blurred, a striped pattern may appear if images with many vertical lines are displayed, or the image’s width may change. For computer signals with which are projector-compatible, the sampling frequency is adjusted automatically even when the AUTO SET button is not pressed.

*Sampling phase

The sampling phase is the timing at which the computer’s analog RGB signals are sampled. If the sampling phase is off, the individual dots cannot be sampled at the proper timing, resulting in blurred or flickering images.
