Phase; Clock; Display Control - Advantech PDC-190S User Manual

A.10

Phase*

Selecting this control allows you to adjust the frequency / sampling rate of horizontal
pixels, to equal the video source's value, thus minimizing the screen artifacts of shim-
mering vertical lines.
Note! This setting is only available on D-sub (VGA).
A.11

Clock*

Selecting this control allows you to adjust the ADC (analog/ digital conversion) sam-
pling clock phase so that the screen image appears crisp and focused. Normally,
Auto Tune is sufficient to complete this task in automatically without user intervention;
the Phase control allows you to adjust it manually in more precise manner.
The Phase and Clock adjustments allow you to more closely adjust your monitor to
your preference. If satisfactory results are not obtained using the Phase adjustment,
use the Clock adjustment and then use Phase again.
Note! This setting is only available on D-sub (VGA).
A.12

Display Control

Selecting this control allows you to adjust the horizontal and vertical size of the
image.
