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.
