1. Overview
1.1. Introduction
Flat panel displays are quickly becoming the standard in modalities
such as interventional radiology, endoscopy, laparoscopy and
ultrasound applications.
Barco’s 18" MIVD 1218 grayscale flat panel display module offers
flexibility and digital scan conversion for use in modalities.
The panel, featuring an RS232 interface, has a resolution of 1280 x
1024 and complies with worldwide medical approvals.
The accurate signal conversion and wide range of interfacing options
of the MIVD’s dedicated circuitry guarantee image fidelity.
The MIVD 1218 further offers LUT correction, which allows setting
the panel’s transfer curve to viewing standards like DICOM or CRT.
Options
Portrait Accelerator (PA)
The Portrait Accelerator automatically adapts the orientation of the
image to the physical orientation of the display panel. The system
makes it possible to display a portrait resolution image on a portrait-
oriented display without additional software.
Tilt & swivel foot
The tilt & swivel foot allows ideal positioning of the panel, in height
and viewing angle.
Most of the photos in this manual show the model with the tilt &
swivel foot option.
Memory scan modes
The memory of the display contains maximum 200 fixed and 28
programmable scan modes.
When you connect a video signal, the display checks in the memory
for a matching scan mode.
If it finds one, it selects the corresponding settings and parameters
from the memory. If it does not find a matching scan mode, the
display uses default settings to display the image.
When you make adjustments and save the changes, the current scan
mode is saved as programmable scan mode. If this happens while all
programmable scan modes are occupied, the oldest programmable
scan mode is overwritten automatically.

3.4. Calibrating the display*
* Not in DVI mode
When do you need to calibrate?
It is necessary to perform the Level and Phase calibrations in the
following cases:
•
•
The first time you use the display
After connecting or selecting another video source
We recommend you use the automatic calibration routines only. The
manual calibration controls are intended for advanced users who
wish to fine-tune the automatic calibration result.
Required test pattern
To obtain good results with the automatic calibration routines, it is
necessary to have a good image on which to perform the
calibrations.
For Phase calibration, the pattern should contain sharp black-white
transitions, like a line pattern or characters.
For Level calibration, the pattern should contain parts that are
completely black (0% video amplitude) and parts that are full white
(100% video amplitude).
For Total Autoset, the pattern should contain:
-
-
-
sharp black-white transitions (see above)
0% and 100% video parts (see above)
white or gray (min. 50%) pixels at the edges of the image (left,
right, top and bottom).

Input Selection
This setting allows you to define how the display will determine which
input to select: Analog (composite video input) or DVI.
These are the possibilities:
Automatic .................If Automatic is selected, the selection of the
input is determined according to the following
priority: 1) DVI input, 2) BNC inputs
A check mark (3) means On, a cross (2)
means Off.
Analog ......................When on, the analog video input is selected.
Consequently, the Automatic setting will be
switched off.
A check mark (3) means On, a cross (2)
means Off.
DVI ...........................When on, the DVI input is selected.
Consequently, the Automatic setting will be
switched off.
A check mark (3) means On, a cross (2)
means Off.
Test Pattern
The display contains an internal grayscale test pattern. Switch it on in
case you want to do a quick visual check on the display quality.
A check mark (3) means it is switched on, a cross (2) means it is off.
Note: The test pattern runs independent from the signal input and the
actual scan mode.
Lookup Tables
This setting allows you to select a lookup table for the current scan
mode.
You can select the following lookup tables:
Panel ........................Select a panel lookup table in case the graphic
board that generates the video signal already
provides gamma correction, a display function
or a non-linear lookup table.

DICOM .....................Select a DICOM lookup table for most medical
viewing applications. The DICOM function
results in more visible grayscales in the images.
CRT..........................Select a CRT (gamma) lookup table in case the
display is used to replace a CRT display.
Apart from these factory lookup tables, there is a User programmable
lookup table. It is default filled out with the DICOM lookup table
(dedicated software needed to re-program it).
Filter*
* Not in DVI mode
The display electronics provide 4 different low-pass filters to filter
possible high-frequent distortion from an analog video signal.
Select a different filter in case the image contains high-frequent noise
or distortion. Select the filter that gives the best result.
Re-calibration of the phase is necessary after selection of a different
filter.
Power Led
This setting allows you to switch off the power LED.
A check mark (3) means it is switched on, a cross (2) means it is off.
Note:
The LED’s orange DPMS state is not influenced by this setting. So,
when the display goes into power-saving mode, the LED will turn
orange, even if it was switched off by this setting.
ALC active
This setting allows you to switch ALC (Ambient Light Compensation)
off or on.
The ALC system automatically adapts the display light output,
depending on the ambient light in the room. The ambient light is
measured by the ALC optical sensor located at the front of the
display.
DPMS active
This setting allows you to switch DPMS (Display Power Management
System) off or on
Orientation**
** Only when Portrait Accelerator is installed
Select the desired option:

Auto..........................The display selects portrait or landscape
reproduction automatically, depending on the
orientation of the panel.
Portrait......................The image is reproduced in portrait orientation.
Landscape: The image is reproduced in
landscape orientation.
De-interlacing*
* Not in DVI mode – Visible only when the input signal is interlaced
This setting allows you to select the algorithm used to convert non-
interlaced into interlaced signals.
These are the possibilities:
Line rep. ...................Use the line repetition algorithm for moving
images. As a drawback, this algorithm may
cause flicker.
Field insert................Use this algorithm for static images
Median......................Use this algorithm for images containing static
and moving parts
Fuzzy........................This motion-adaptive algorithm, using fuzzy
logic, analyses the image content and selects a
de-interlacing method automatically.
In nearly all circumstances, this method gives
the best result and is the preferred de-
interlacing algorithm.

CAL options
Here you can change parameters for phase and level calibration
User manual MIVD 1218

Download from Www.Somanuals.com. All Manuals Search And Download.
Equal pix...................Selects the number of successive pixels with
the same digital value used in amplitude and
black level calibration.
Decrease this number for video signals with a
lot of noise.
Phase offset .............Adds a phase difference to the value derived
after phase calibration.
This can be used to compensate for distortions
on the video signal.
Apix Range...............Contains the functions Clk Start and Clk Stop.
These are the numbers of pixels for the Autocal
routine to start and stop with.
By default, the number of lines in the image is
taken as the number of pixels for Autocal to
start its calculations. The double of this start
number is taken as the number of pixels for
Autocal to stop. By increasing the start number
and decreasing the stop number, you narrow
the range for the Autocal routine. As a result,
Autocal goes faster.
OSD
Here you can change some of the on-screen display’s (OSD)
parameters.
These are the OSD settings:
Hor. Pos ...................The horizontal position
Vert. Pos...................The vertical position
Timeout On...............To switch the OSD timeout on or off. A check
mark (3) means it is switched on, a cross (2)
means it is off.
When switched on, the OSD disappears
automatically after 300 seconds of inactivity.
ALC
ALC (ambient light compensation) is a system that adapts the panel
light output automatically, based on the ambient light measured by
the ALC sensor at the front of the display.
Here you can adjust the ALC parameters.
These are the ALC settings:
min Light...................This is the panel light output that corresponds
to the minimum ambient light, measured by the
ALC sensor.
User manual MIVD 1218
25
Download from Www.Somanuals.com. All Manuals Search And Download.
max Light..................This is the panel light output that corresponds
to the maximum ambient light, measured by the
ALC sensor.
min Thresh ...............This is the minimum value of ambient light.
Below this value, ALC will remain inactive.
When the measured ambient light reaches this
value, the panel light output will be set to the
min Light value.
max Thresh ..............This is the maximum value of ambient light.
Above this value, ALC will stop controlling the
light output. When the measured ambient light
reaches this value, the panel light output will be
set to the max Light value.
Scan mode
The memory of the display contains maximum 200 fixed and 28
programmable scan modes.
When you connect a video signal, the display checks in the memory
for a matching scan mode.
If it finds one, it selects the corresponding settings and parameters
from the memory. If it does not find a matching scan mode, the
display uses default settings to display the image.
When you make adjustments and save the changes, the current scan
mode is saved as programmable scan mode. If this happens while all
programmable scan modes are occupied, the oldest programmable
scan mode is overwritten automatically.
The Scan Mode menu contains the following function:
Find next mode.........Select if you wish to select another scan mode
from memory that matches the incoming video
and sync signals. The number displayed in the
OSD is the number of the actual scan mode’s
memory location.
Factory reset
Can be used to re-initialize the display.
Actual mode .............Restores all factory parameters for the current
programmable mode.
All modes..................Restores all factory parameters for all
programmable modes.
Control wheel
This function allows you to disable the control wheel function so that
the on-screen display cannot be used.

4. Maintenance
Panel
Take care not to damage or scratch the panel. Clean with a soft
woolen or cotton towel. Use a watery solution or a mild commercial
glass-cleaning product.
Cabinet
Do not use chemical cleaning products, benzene, toluene, xylene or
other solvents. Clean with a soft cloth dampened with mild detergent
and water. Repeat with water only and wipe dry with a dry cloth.
Removing dust from the rear of the glass panel
It may be possible that dust particles have entered the display and
are stuck to the rear of the glass.
We recommend to let this cleaning procedure be done in a BARCO
service center.
However, when really necessary, you can perform the cleaning on
site if you can work in conditions that are as clean and dust-free as
possible. This is to avoid more dust entering the display when
opening it.
To remove the glass panel:
1 Switch off the display.
2 Tilt the panel.
3 Unscrew the 4 sunken screws at the rear, fixing the glass panel
and bezel.
4 Remove the bezel with glass panel.
Cleaning instructions:
-
Dust, fingerprints, grease etc. can be removed by using a soft
damp cloth (a small amount of mild detergent can be used on the
cloth, NOT solvent).
-
-
Do not apply liquid directly to the LCD surface as excess liquid
may cause damage to internal electronics.
Take care not to touch the I-guard light sensor on the LCD panel.

5. Troubleshooting
Calibration not successful
After an unsuccessful calibration, the message “Failed” appears on
the screen.
Possible solutions:
-
Use another test pattern for performing the calibration. The text in
§ 3.4, Calibrating the display , explains what test patterns to use.
-
Check the quality of the signal source and signal cables. Poor
video signals or cables can result in unsuccessful calibration.
Pixel Faults
Permanently dark or bright pixels can happen to TFT displays. 20 or
less permanently dead pixels do not make out a good case for
exchanging the unit.
Please contact our Customer Service Department if the number of
pixel faults exceeds the above-mentioned figure.
