• Analog RGBHV: Select Analog RGBHV to adjust the Gain and Offset for the red,

green and blue channels. These controls are similar to those in the

White Balance

menu (described above), but only affect RGB high-definition signals.

The Gain controls increase or decrease the full-scale input range; the Offset controls

shift the entire range, resulting in a change in brightness.

Figure 4-6 shows how the

Gain and Offset controls interact with each other.

• Adjust the Brightness and Contrast associated with a Video Black Level. The

Brightness and Contrast settings made here can be recalled by choosing the

associated Video Black Level, either here (choose “Setup,” then select 0 IRE or

7.5

IRE) or in the Video Black Level sub-menu (refer to Video Black Level on

page 60).

• Adjust the Gain and Offset for the Pb and Pr channels. These controls only affect

component high-definition signals.
