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
HL1928M 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"). 6.3
