9.11.3 RGB Source Menu Items
Once the Autoset sense setting has been made, this menu item is accessed
and activated. The Autoset sense utility will then correct the pixel phase and
then position the Top Left portion of the image and the Bottom Right portion of
the image. Once complete it then resume inactive status.
Since an image pixel is a very small element of the total image, it’s possible
for your unit’s Analog to Digital converters to wrongly sample the picture on
the edge of each pixel thereby losing image resolution and creating image
noise. The Input pixel phase adjustment allows you to change the position
(from 0 to 31) where the pixels are sampled, relative to the horizontal sync
signal.
To make this adjustment, select an RGB source and then provide an image
from that source with fine detail, preferably with very sharp vertical lines.
Adjust this value until you see the sharpest image. Alternately, adjust this
value to give the worst (noisiest/softest) image, and then add or subtract 16 to
get the optimum value.
Note that the AUTOSET function (for RGB inputs only) will attempt to
automatically work out the best value for this setting.
There are several types of signals that are called RGB signals as a generic
term. Each has slightly different characteristics that set it apart from similar
RGB signals – such as how the synchronization signal is sent. This menu
item lets you set the input type to use.
Available options let you select whether the input is standard RGB or YUV
(including YPbPr signals with a tri-level sync). For some units, it also allows
selection of break-out BNC connectors to be used instead of the normal
connector (signified by B- in front of the signal type).
This menu item lets you adjust the individual RGB or YUV/YPbPr signals, in
case one component is at a different contrast to other, or if they all need to be
boosted or lowered.
