that source will thus be improved, not just the one you used for the
adjustment. When finished press the knob again. The brackets will stop
flashing and the value will be stored in temporary memory. Hold the knob in
until the unit ‘Beeps’ to record the value in permanent memory.
12.5 RGB Input Type
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. Move the Menu Select knob from the Input Pixel Phase screen
and bring up the screen shown above.
(Again, we are assuming you
performed a factory reset as suggested. If you did not, you won’t necessarily
see the same screen when you rotate the Menu Select knob. It may be
another type of signal [not RGB] or it could be parked on a button other than
Input Button number one as it is in our example).
Assuming you are seeing the same LCD screen as displayed above, press
the knob once and the flashing brackets are your notification that you can
change the type of RGB signal present on the input button. The device begins
its offerings on the default signal type of
RGBHV . This abbreviation means
Red, Green, Blue imagery plus Horizontal and Vertical Sync. If you rotate the
knob one detent to the right, you’ll see
RGBS. This means Red, Green and
Blue plus a single Sync signal. A further rotation to the right and you will see
RGsB displayed between the flashing brackets. This means that you have a
Red, a Green and a Blue image plus a sync signal superimposed on the
Green channel. Finally you have the choice of the
YUV family of signals
(RGB) and also the “tl” variant of YUV with Tri-Level Sync signals for 1080i,
720p HDTV type signals.
Make your choice and then press the knob once to lock in your choice for the
input you selected. Press and hold until you hear the beep to permanently
store the selection. Manually select any other Input Button that has an RGB
signal present and perform the same selection as before until you have all the
RGB signals properly defined.
12.6 RGB Contrast
One desirable feature of an RGB signal is the ability to adjust the individual
signal components with minimal effect on the other components. With a CV
(Composite Video) or YC (Component Video) signal it’s not easy to make an
adjustment to one color without causing a knock on effect on another portion
of the image. With RGB images you can (for instance) have an image of
green grass and blue sky and make the grass bright green without having any
