Adjusting Input Levels

m70L Installation & Configuration Guide

These controls are advanced level controls and should not be adjusted unless you 

have been instructed by the factory or are familiar with black level adjustments. 

Digital computer sources do not normally need adjustment, but the controls are 
there if you need them. They are used to correct the digital blacks that come from 
video cards that have incorrect levels.

Select a source in the 

PICTURE

 menu.

To view the 

INPUT

 

LEVELS

 menu, press 

LEVEL

 

on the remote. (The 

INPUT

 

LEVELS

 

menu looks different for different colorspaces. The 

INPUT

 

LEVELS

 menu for Digital 

RGB sources is shown below).

If you have changed black and white levels, select the 

SET

 

TO

 

NOMINAL

 

FOR

 

RGB

 

LEVELS

 line to change them back to the default. This is the default for most 

sources.

It would be rare for you to adjust black and white levels for a digital source. 
However, depending on the source, what black and white “mean” can be 
different. In most cases, black will be 0 and white will be 255. However, for some 
sources, such as DVD players, black can be 16 and white can be 235. If this is the 
case, select the 

SET

 

TO

 

NOMINAL

 

FOR

 

VIDEO

 

LEVELS

 line and press 

ENTER

. 

This 

will change the black and white levels to the required values to correctly display 
the range of colors in the display.

Although it is not required, we recommend that you save the configuration to a 
memory slot. (See "Saving Configurations" on page 74.)
