Note on adjustment
● Use the SMPTE test pattern.
● Adjust the brightness so that image sections with 5 % and 0 % gray value still visibly
contrast.
● Adjust the contrast so that image sections with 95 % and 100 % gray value still visibly
contrast. To adapt the luminosity to the ambient lighting, adjust the backlight brightness
(caution: factory-set brightness is no longer observed).

7.4.4 Adaptation of display – video source / graphics card
As with all monitors, the Flat Panel Display also has certain limits, e.g. maximum resolution
and refresh rate.
● The graphics card must be set when using the display such that the limits are observed.
RGB sources (via 15-pin Sub-D or DVI-I connector) supply analog signals which are
basically intended for conventional CRT monitors and which are processed directly by them.
In contrast, the analog signals must be converted for the Flat Panel Display into digital
signals by a video digitizer. Depending on the source, cable length and video mode (e.g.
VGA, SVGA, XGA), this conversion may cause certain deviations which cannot be corrected
fully automatically by the Flat Panel Display.
A manual fine adjustment is therefore necessary during which the Flat Panel Display (or,
more precisely, the video digitizer) is matched to the respective video source.
The fine adjustment includes, for example, setting the horizontal/vertical picture position and
the picture sharpness. This can be done via the OSD menu.
In order to optimize the display settings for the installed graphics card and guarantee that all
grayscales can be distinguished, we recommend that brightness and contrast are adjusted
only for the analog inputs.
Please note that the calibration (in the look up table) is not affected by these settings (EIZO
GmbH Display Technologies displays are factory-calibrated and retain these settings):
● Use a picture with 0% gray value (black) and a suitable measuring instrument (a spot
meter is recommended) in order to reduce the brightness with the aid of the OSD control
elements until the measuring instrument displays constant values (i.e. the measured
value no longer changes). Then increase the brightness slightly until the display is just
above the lowest black level (one step is generally sufficient).

NOTICE
Fine adjustment of the Flat Panel Display can only be carried out via the two analog
ports (15-pin Sub-D and DVI-I). The digital input (DVI-D) does not require a fine
adjustment since the signal display is always optimum.
