Color
Limiting RGB Range adjusts the color output range
to accommodate those displays which do not
handle 24-bit RGB natively. Many LCDs found on
TVs do not show a full range of RGB for each of the
three primaries, red, green and blue. Each primary
color is represented by an 8-bit value, giving 256
levels of color for each primary. Full RGB displays
accept values of 0-255 for each color primary.
Limited RGB displays only accept values of 16-235,
with values below 15 being designated as black and
values above 235 being designated as white.
The identical RGB value will not produce the same
color in limited RGB versus full RGB because limited
RGB tries to cover the same color space as full RGB
but has fewer values to cover the range.
You should use Full RGB if your display supports
it. If you turn on the Limited RGB Option and see
black turn to dark gray, then you should not use
this option. If the black stays black, then keep this
option on.
The Lock Gamma Sliders Together option disables
your ability to set the gamma for Red, Green and
Blue independently.
Red, Green & Blue sliders can be set from 1.00 to
1.99 in .01 increments. You may come close to the
gamma of a CRT with the sliders at 1.20 without
scanlines and 1.40 with scanlines.
Advanced Mode
Enabling this option adds the Buffer Mode, Extra
Features and Color options to the Video Submenu
and turns the simplified Screen Size options into
the Width & Height options.
