PLUGE patterns (2 white and 2 black)
These patterns are used to visually adjust brightness (black level) and contrast (white level) as well as to
verify the display is in the correct color space mode.
RGB video is normally sent using all 256 bits (in 8 bit color)
but YCbCr (component video) sets black at 16 and white at
238. This allows room above and below the active video for
below black and above white. PLUGE patterns are
specifically designed to allow quick visual setting of the
black and white level.
Using the black patterns (background is 16) so set the
brightness level on the TV until you can just see the
difference between 16 and 17. Depending on how fine the
display adjustment is, you may not be able to get this
exact, but 16 should be black and 17 grey. Everything below 16 should not be distinguishable. Having this
setting correct will bring out the details in dark pictures.
Using the white patterns (background is 238) set the contrast level on the TV until you can just see the
difference between 237 and 238. Many LED and LCD TVs will not have enough contrast range to allow this
to be set completely correct, and it is normally improper to set contrast to very high values. So it you
cannot make everything above 238 clip (disappear) then set contrast to around 75% and double check
using a dynamic range sweep with CMS software.
