First operation
Trackball
The trackball enables the user to navigate through the menus, change the value of a
selected item and to move the pointer (only in pan&zoom mode).
The
button enables the user to edit and confirm a value or setting in the toolbox or
OSD menu. The
button also acts as a “left” mouse button for drag and zoom
operations in the pan&zoom mode.
Status bar
The status bar is shown at the top of the screen and contains relevant information related
to the settings of the input signal settings and the setting of the display unit. The line
highlighted in white indicates the active window.
Calibrated settings
The display unit is a calibrated instrument that continuously monitors several parameters
to ensure correct representation of colors and luminance levels.
The user can decide to run the display unit in a non-calibrated mode by adjusting the
settings defined by the image adjustment knobs (picture, background, saturation and
hue). When the values of the image adjustment knobs deviate from the calibrated values,
the orange light above the knob will light up. Press (
) the knob to return to the
calibrated (default) setting (when the picture adjustment bar is visible).
The user can also decide to show only one of the 3 color channels or to convert the video
signal to monochrome.
In all these cases also the
button will light up orange. Press (
) the
button to go
back to the calibrated status of the display unit.
2.6 How to setup the display unit
In this section a number of settings are discussed which are primarily preference settings
that can be set by the user.
• Set the
Picture
(
!
)
to the required luminance. The default value is 100 cd/m
2
. The
display remains calibrated in the allowed picture range (45-150 cd/m2). The picture
of the display unit can thus be adjusted according to the preference of the customer.
• The display unit is a digital display, so the
signal black level
is always mapped cor-
rectly to the LCD black. Depending on the ambient light illumination and reflection
from the screen it might be necessary to align (lift) the black level using a “Pluge”
test pattern and adjusting the
Background (
)
of the display unit.
• Toggle the
button until the required
color working space
is selected (e.g.
SMPTE RP145). The color working space determines the color primaries (compara-
ble to the CRT phosphors) that are used to display the image on the screen. This
setting is a geographic region preference setting.
• Enter the color working space toolbox by pressing
(
- long press). Set the
required white point (default D65). Store the setting under a “Custom” preset.
• Enter the input window menu by pressing
or
(
- long press). Set the signal
input range to be visualized on the screen (default 64-1019). Select the OETF (opto-
electric transfer function – ‘gamma’) (default is ITU.709).
• Input signals which have an identifier packet describing the type of input signal are
processed automatically by the display unit. When the
input signal does not have
an identifier packet
, it may be that the display unit is not able to display the input
