PICTURE
The Picture menu provides video adjustments for each source. Do not make adjustments in this menu if your
display has not been calibrated – see the Test Patterns section and return after calibrating your display.
Input Color Space
For YCbCr input, the default is Auto, which switches between HD and SD color space according to whether
input has HD or SD resolution. In case the source contains the wrong color space for its resolution, for
example, a cable box that converts 480i channels to 1080i output without converting SD color space to HD
causing some unnatural hues, the color space can be corrected by forcing the setting to SD or HD.
If the source is in RGB format instead of YCbCr, choose between Studio and Extended – detail in dark scenes
can be used to find the correct setting. The default is Studio.
Brightness / Contrast / Color / Tint
If a source needs Brightness (black level), Contrast (white level), Color (saturation), or Tint (hue) adjustment,
you can do it here. The default for each of these is 50. If the source component puts out RGB and output in
menu1 is set to RGB, Color and Tint are not adjustable so that unnecessary color space conversion is
avoided. If you need to adjust the image in such a case, set the source component to YCbCr output.
Film Mode
Did the source originate from film or from video? If from a video camera, which type? If it’s a film source on
TV, was a regular pattern of fields deleted to change the playing speed? Is it animation, and if so, according
to which animation spec? Is it a mix of sources edited together? Are video characters being scrolled across
a film source?
For a video processor to provide best image quality, it must detect the source’s cadence, or pattern of field
sequence, and deconstruct it accordingly. The Sigma Designs VXP processor can not only do that, it can do
so even when the input is high-definition. Film Mode can be overridden by changing the setting from Auto to
Off, but don’t do it unless you need to.
