Input selection
Input selection
The MDSC-1119/MDSC-2124 can be equipped with numerous different
video inputs. The available inputs may depend on the customer’s
requirements.
Input selection can be done in 5 ways:
• Automatically, by means of the Source Scan system
• By assigning a source priority
• Quick input selection by using the general purpose switch.
• Quick input selection by using the navigation keys without
entering the OSD.
• Using the Input selection menu in the OSD.
These 5 possibilities are described more in detail below.
Source scan
Source scan is a system that automatically scans all video inputs in the
display until it detects a correct video signal at one of the inputs. When
that video signal disappears again, the source scan system
automatically starts again, looking for another video signal.
The source scan system can be enabled or disabled in the Setup menu.
Source priority
In the Setup menu you can give priority to an input source. If a priority
has been established, the display will automatically select this source if
a signal is present on this input. The priority input selection will overrule
the manual input selection. For more information, please refer to
“Setup” on page 24.

How to adjust the display to a new video signal
About video timings in the display memory
The display contains a list of video timings according to VESA and
other video standards. If you connect a video signal that matches a
timing from the list, it is adjusted automatically according to a
number of parameters that are defined in the list. If the connected
video signal has a timing that is not in the list, the display selects
the timing from the list with the closest match and also adjusts the
signal according to the corresponding parameters.
If the user makes any additional adjustment, the video signal
(with its adjustments) is stored as user preset. The next time this
video signal is connected and selected, the display recognizes it as
one of the user presets and reproduces it with the corresponding
adjustments. The signal is recognized by its timing and the type of
video input it is connected to. This means a certain video signal
connected to the VGA input or to the BNC inputs can be stored as
two different user presets.
Additionally you can store a user preset as User Profile and give it
a name. For more information, please refer to “User profile
menu” on page 17.
Note that camera selection may change some of the settings for
certain input timings, depending on the requirements for the
selected camera. The camera selection will affect the user preset,
but will never affect a user profile.
31
How to....
The display memory can contain maximum 20 different user
presets. When the memory is full, the last user preset is
overwritten when a new video signal is adjusted.
When Restore Factory Settings from the Advanced menu is
selected, all the user settings, including the user presets, are
cleared.
To adjust the display to a new video signal:
a) Digital video signals:
Normally a digital video signal (on SDI or DVI-digital input) needs no
additional adjustment. If desired, you can change the color temperature
or display function in the Advanced menu. You can also perform an
Autosetup in the Adjustments menu, but only geometry will be
adjusted.
b) Analog video signals:
An analog video signal may require some adjustments the first time it is
connected.
Note: If an analog video input is selected, you can perform
Autosetup in the Adjustments menu, automatically adjusting
phase, geometry and gain offset.
If Autosetup is not available or does not give satisfactory results,
proceed as follows:
1. Display a dot on-dot off test pattern.
Tip: You can find a suitable test pattern on the product CD-ROM.
2. In the Advanced menu, adjust Phase.
3. In the Advanced menu, adjust Frequency.
4. In the Adjustments menu, adjust Brightness, Contrast, Color, Hue
and Sharpness, if necessary.

How to make a PiP setup
Setting up picture-in-picture
Picture-in-Picture (PiP) is a feature where two different video signals
can be displayed next to each other or on top of each other in 2
separate frames. You can adjust the way in which the video signals are
displayed and store this in a PiP layout.
The display has a number of predefined PiP layouts that can be
modified by the user. A PiP layout determines the video input, size,
position, scaling and aspect ratio for both PiP frames.
Note: The PiP menu is not available when a priority input source
is selected. See also “Source priority” on page 6.
To change a PiP layout, proceed as follows:
1. In the PiP layout submenu, select one of the PiP layouts from the
PiP layout submenu. Beware that you will overwrite this layout.
2. Select the desired PiP1 input from the list of available video input
sources.
3. If you wish to change the aspect ratio of the PiP frame, exit the PiP
menu and go to the Adjustments menu to change Aspect Ratio.
This will affect the width of the frame only.
Note: While the Adjustments menu is open, PiP2 frame will not
be visible. It appears again when you exit the Adjustments menu.
4. In the Adjustments menu you can also adjust brightness,
contrast, color, hue and sharpness as desired for the signal
displayed as PiP1.
5. Go back to the PiP menu and adjust Size (scales the PiP frame
proportionally), H Pos and V Pos for PiP1.
6. If desired, select a border color for the PiP1 frame.

7. Select the desired PiP2 input from the list of available video input
sources. See also the note below.
Note: When selecting the video input for PiP2, some inputs may
not be available, depending on the chosen PiP1 input.
8. If you wish to adjust the image in the PiP2 frame, select Toggle
PiP. As a consequence, the video signal from PiP2 now becomes
PiP1. This is necessary because the functions in the Adjustments
menu always affect the image in PiP1 only.
9. Go back to the Adjustments menu and adjust aspect ratio,
brightness, contrast, color, hue and sharpness as desired like in
steps 3 and 4.
10. Go back to the PiP menu and select Toggle PiP again to switch the
second video signal back to PiP2 again.
11. Adjust Size (scales the PiP frame proportionally), H Pos and V Pos
for PiP2.
12. If desired, select a border color for the PiP2 frame.
13. If necessary, select PiP order to change the PiP stacking order.
14. If desired, select PiP layout name to change the name of the PiP
layout.
15. Select Store layout to save the changed layout in the memory.
Note: It is possible to select the same video input for both PiP
frames. However, it is difficult to give them different image
adjustments, as both frames will get the same adjustments every
time you select Toggle PiP.

How to use brightness, contrast and luminance
adjustments
Although they may seem very similar, there is quite a difference
between brightness, contrast and luminance adjustments.
• Luminance adjustment leaves the video signal untouched but
changes the light intensity of the backlight behind the LCD panel
inside the display.
• When controlling brightness, all video levels from black to
white are adjusted. You should adjust brightness to make the
black parts of the image perfectly black. But watch out not to
decrease brightness too much (avoid losing information in the
dark parts of the image).
• When controlling contrast, the black level remains constant and
the white levels are adjusted, changing the luminance
difference between black and white. You should adjust contrast
after brightness has been adjusted, to make the white parts of
the image perfectly white. But watch out not to increase
contrast too much (avoid losing information in the bright parts
of the image).
Important: If you adjust brightness and contrast incorrectly, clipping of
the video signal may occur: When brightness or contrast is too high, you
may lose information in the bright parts of the image because the image
is too bright. When brightness is too low, you may lose information in the
dark parts of the image because the image is too dim.
Some suggestions:
• If you experience the image is too dim, increase the contrast so
that no clipping occurs (no information lost in the bright parts).
Next, increase luminance slightly, if desired.
• If you experience the image is too bright (clipping occurs in the
bright parts) decrease contrast until the clipping is solved.
Luminance adjustment will not have any effect here.

How to adjust color temperature
The MDSC-1119/MDSC-2124 display contains 3 pre-defined and 1 userdefined color temperatures. You cannot adjust color temperature
separately for the 2 picture-in-picture frames. It can be adjusted only for
the whole display.
To adjust color temperature:
1. Open the OSD and select menu Advanced.
2. Select submenu Color temperature.
3. Select one of the pre-defined color temperatures or select
Adjustable or User.
4. If you selected Adjustable, return to the Advanced menu and
adjust the slider in the Color Adjustment function.
5. If you selected User, return to the Advanced menu and select
Customer color.
6. In the submenu, for red, green and blue separately, adjust the
intensity from 0 to 100 %.
