3.2 Adjusting Each Margay To Its Source

3.2.2 Adjusting to Computer Sources, Digital

Digital sources do not normally need adjustment, but the controls are there if you need them.
These controls are advance level controls and should
not be adjusted unless you have been briefed by the
factory or are familiar with black level adjustments.
They are used to correct the digital blacks that come
from video cards that have incorrect levels.
Don't use these controls unless you have been briefed
by Planar or you are familiar with black level
adjustments. These controls are usually not necessary.
