CLOCK PHASE
For optimum image quality of analog RGB (or YUV/HDTV) inputs, it is
important that the sample clock in the Analog / Digital Converter (ADC)
has the same phase as the original sample phase of the input signal. If
the phase is not correctly set, the image may appear to have noisy or
indistinct edges.
Use the following procedure to set the ADC phase:
•
Be sure that the input signal has a lot of high frequency detail.
•
In the Input Timing section of the Input Properties page, click
on the UP button next to the ADC clock phase spin box and
view the output image. If the image quality deteriorates, click on
the
DOWN button and continue clicking on the button until the
image quality stops improving.
•
The optimum point has been reached when you can click on
either the
UP or the DOWN button and the image quality can be
seen to deteriorate.
This parameter is saved along with the other parameters in this window
when you save a new timing entry (see
Creating a New TIming Entry ,
page 47 for details).
