Select Auto Config to perform an automatic input configuration on the selected
source.
Note In this mode, for the selected image, the system finds the first
and last pixel on each edge, and ensures (to the best
possible extent) that the entire image is visible. In addition, if
the input is analog, the system automatically phases the input
to determine the correct sampling phase.
Tip Ensure that there are non-black pixels around the extreme
edges of your active video, in order for the image to be
properly sized by the Auto Config function. For example, if
you use a Windows desktop with a high luminance
background, the Auto Config function will be accurate. If, on
the other hand, you use a desktop image with a black border,
the image will not be properly sized.
Sampling — select this function to change the sampling for the selected input.
Available values are: Oversample and 1:1 (default). Please note:
~
When 1:1 Sampling is selected, the system provides pixel-for-pixel
sampling, and generally better image quality.
~
When Oversample is selected, the system performs multiple samples
for every pixel, with a resulting "softer" image.
~
Oversample is only available for RGB and YP
~
All other input types have defined sample clocks that are inherently 1:1.
If the input is set to one of the other types, the value is [1:1].
Sample Phase — This selection is only available when Sample Mode is 1:1 and
the input is analog RGB or YP
The sample phase value is initially filled in by the Auto Config command, or set to
the default value. You can further fine-tune the image by adjusting the sample
clock phase directly.
~
Adjustment range: -16 to 15
~
Default: 0
H Total — adjusts the total pixel count per line. This value cannot be adjusted if
the input type is DVI / SDI.
H Position — adjusts the offset of start of active area from H sync.
H Active — sets the size of the active area.
V Total — indicates the total line count per frame. This value is measured, and
can never be adjusted. Its value will always be shown in brackets.
V Position — sets the offset of start of active area from V sync.
V Active — sets the size of the active area.
