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).
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.
