In order to ensure safe operation of the equipment, close attention must be
paid to the information contained in this Instruction Manual as well as the
warnings in Section 2 "Safety precautions".
Caution Information for end customer
None of the settings must be changed on site by the user, otherwise the
guarantee is canceled. This also applies to settings made using the HL1916
keys. These are therefore locked for certain applications. If settings have to be
changed, please contact the responsible servicing department.
The display is designed for individual connection to a graphics card with a
power supply of 100 or 240 Volt (TN-S system with PE conductor). If the
display is to be used in a sequence of several displays, or if it is not exactly
known whether the graphics card standard can be output by the display, refer
to Section 5.1 "Connection of the flat panel display".
In order to start the unit properly, the following steps should be carried out in
the given sequence.
4.1 Connecting the power and signal cables

4.1.3 Little cover (attaching)
Lead the monitor end of the cables through the little cover’s cable duct.
Connect the little cover to the rear cover.
4.2 Power up the display
Power up the display. The operation LED lights up.
4.3 Adjusting the image geometry
The display automatically recognizes the used standard, and set-up values for
each standard are preprogrammed. However, depending on the graphics card
used, it may still be necessary to align and size the picture for the selected
standard (see Section 6.1 "Picture adjustment"). Normally auto adjust will
work.
4.4 Adjusting the brightness and contrast
The brightness and contrast must be adjusted for the respective graphics card
(different output levels) in the system on site.
Note on adjustment
−Use the SMPTE test pattern.
−Adjust the brightness so that image sections with 5% and 0% blackness still
visibly contrast from one another.
−Adjust the contrast so that image sections with 95% and 100% whiteness

19"LCD MONITOR
REV A
13
still visibly contrast from one another. To adapt the luminosity to the ambient
lighting, adjust the backlight brightness (note: 500 cd/m² factory setting is
then modified).
4.5 Screen saver
A screen saver function should be used in order to reduce "image sticking"
which can occur in TFT displays. It is high risk to display a static graphic
over half an hour. Image sticking is the effect where a faint image of the
previous screen contents can still be seen after the display contents have
changed. By using a screen saver with permanently changing screen contents,
unnecessary effects of the same image are avoided.
If the keyboard is locked, contact the servicing department in order to unlock
it. The guarantee is cancelled if you unlock it yourself!

6. Adjustments
6.1 Picture adjustment
This section describes the settings for operation of the flat panel display with
a video source. The most important settings are:
Adjusting the graphics memory of the video source
As with all monitors, the flat panel display also has certain limits, e.g.
maximum resolution and vertical frequency. The graphics adapter must be set
when using the flat panel display such that the limits are observed.
Fine adjustment of the flat panel display
Note
Fine adjustment of the flat panel display can only be carried out via the analog
port 15-pin SUB-D. The digital input (DVI-D) does not require a fine
adjustment since the display signal is always optimum.
RGB picture sources via 15-pin Sub-D 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 a flat panel display into
digital signals by a video digitizer. Depending on the picture 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 comprises e.g. setting the
horizontal/vertical picture position and the picture sharpness. This can be
carried out for the color flat panel display HL1916AMT using an OSD menu.
To optimize the display settings for the installed graphic board, and to ensure
all gray levels are distinguishable, we recommend to adjust the brightness and
contrast levels for and only for analog inputs. Note that the calibration (in the
Look Up Table) is not changed by these adjustments (All the monitors are and
remain factory calibrated):
Using a 100% black picture and an appropriate measurement device (a spot
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

19"LCD MONITOR
REV A
17
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 monochrome flat panel
display HL1916T 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").
