where 0-mv is minimum luminance. Rise and fall times for the input signal (10% - 90%) will be ?5-ns (Figure 6).

When terminated with a 75-ohm termination, the dark state (black level) is defined as a level between 0-mv and 10-mv. The white state (full white) is dependent on the VGA controller driving the Monitor. Maximum levels may range from 550-mv to 714- mv. Nominal 680-mv input voltage shall be defined as the default for supplier setup requirements.

Displayed image intensity and colors will change linearly with the video analog input. This is necessary to provide a uniform user color change on the screen in response to a uniformly stepped analog input. The Monitor must be capable of resolving a minimum color range of 262,144 displayable colors (6 bit resolution for Red, Green and Blue). This interpolates to 64 shades of gray (or color) at the Red, Green, and Blue analog video inputs. Accomplishing specified shades of gray requires a “Video Gain” control adjustment (Section 15.0 ) of Red, Green, and Blue analog input signals based on the maximum output level range previously specified.
