Adjusting Input Levels
Adjusting Levels for Digital Sources
Caution: 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.
1Select a source in the PICTURE menu.
2To 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).

Set to Nominal for RGB Levels
Set to Nominal for Video Levels
3If 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.
4It 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.
5Although it is not required, we recommend that you save the configuration to a memory slot. (See "Saving Configurations" on page 74.)
