meter recommended), decrease the brightness level using the OSD controls
until the measurement device displays a constant level (i.e. the measured value
no longer changes). Once this is achieved, increase the brightness level slightly
until the display is just above the absolute lowest black level (one step is
generally sufficient).
Similarly, set the white level using a 100%-white test pattern and the
measurement device. Only the contrast level should be adjusted to ensure that
the black level remains unchanged.
• Control again the black value did not change. In case it did you need to
duplicate the two previous steps until it does not change anymore (cause:
pedestal).
Increase the contrast level until the measurement device no longer detects an
increase in luminance. Once this is achieved, decrease the contrast level
slightly (1 or 2 steps is generally sufficient).
At this point, the display is configured for optimal performance with the installed
graphic board. If one is not yet satisfied with the luminance level, the black and
white levels can be further increased by adjusting the backlight level in the OSD
menu. Please note that higher backlight level settings tend to reduce the
stability of luminance over time.
6.2 Optimum picture quality
In order to achieve an optimum picture quality, the color flat panel display
DSC1913-D should be operated with a graphics resolution of 1280 x 1024
pixels (settings for graphics card in the PC). When adjusting the picture position
and size, ensure that the picture appears exactly on the active surface of the
display and that it is not offset by even one pixel. For example, if the horizontal
position is offset by one step to the right, the right-hand edge of the picture will
disappear, and a black pixel column will appear at the left-hand edge. And
similarly for an offset to the left, top or bottom. If the vertical lines are still slightly
fuzzy, adjust the setting "Frequency/phase" (see Section 6.4 "Description of the
menus").
