          PLUGE (1/3)

The #Ypicture line-up generation
equipment#Y (PLUGE) is a test
pattern used to adjust the black
level and contrast of a video
signal.

The pattern in this suite is
mainly designed to adjust the
black level. The control for
setting this on your TV is
usually named #YBrightness#Y.

This adjustment ensures that
anything intended to be black is
actually black, and allows all
detail to be seen on dark scenes.

There are three bars at each
side, you can highlight them
with the #GCL#G button.

                     #C(cont...)#C
          PLUGE (2/3)

The #GA#G button changes between
#GNTSC#G and #GRGB Full Range#G [0-255]
when in any NTSC mode.

The values of the bars depend on
your current video mode. Reduce
the #YBrightness#Y until the desired
bars are no longer visible, and
then slowly raise it until they
are #Gjust#G visible, and go back one
notch where they blend with the
background. 

For games always use #GRGB Full
Range#G. The 1 IRE bars are the ones
you should calibrate against. The
values of the bars are: 1, 2 and
3.5 IRE.



                     #C(cont...)#C
          PLUGE (3/3)

Values for the bars when in NTSC
mode are: closest to the center
3.5 IRE, central ones 7.5 IRE, and
outer ones 11.5 IRE. 

When calibrating for NTSC
material, the 7.5 IRE bars should
blend in the background. The 7.5
IRE in NTSC is the black level,
also known as setup.
