Notes
• Automatic adjustment may not be performed properly for signals other than the computer’s
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

.
* 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 may be blurred, a striped pattern
may appear when images with many vertical lines are displayed, or the image’s width may
change. For computer’s signals with which the projector is compatible, the sampling frequency
is adjusted automatically even without pressing the AUTO SET button.
* 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.
