Fine adjustment of the flat panel display can only be carried out via the
analog port. The digital inputs (DVI-D,DP) do not require a fine adjustment
since the display signal is always optimum. 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.
5.2 Optimum picture quality
In order to achieve an optimum picture quality, the color flat panel display
HL3116ST should be operated with a graphics resolution of 3840 x 2160
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 it is not offset by even one pixel.
