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.

the value for contrast and brightness is restored to the calibrated  
position.  
-
The calibrated position for contrast and brightness is determined  
by calibration of the video levels (see § 3.4 below).  
In case you feel unsatisfied with the current calibrated position,  
you need to repeat the calibration. The proper way to do this, is to  
use the automatic calibration routine. However, you can also  
manually change the calibrated positions: The Manual black

output value as before switching it off.  
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).

you have to fill out the total number of pixels per  
line, as defined in the timing parameters of the  
input signal.  
V-position .................Adjusts the image position vertically  
H-position .................Adjusts the image position horizontally  
V-Active....................Allows you to change the vertical size of the  
active video window around the image,  
expressed in pixels. If you decrease this size,  
you may blank a part of the image.  
H-Active....................Allows you to change the horizontal size of the  
active video window around the image,  
expressed in pixels. If you decrease this size,  
you may blank a part of the image.  
Scaling On................When switched on, the image will be scaled  
automatically when possible. E.g., if the image  
is 640x480 pixels, the image will be scaled by a  
factor 2. But an image of 800x600 pixels will not  
be scaled because the native panel resolution  
is 1280x1024 pixels.

selection, Test Pattern, Synchr. Sampl, Lookup Tables, Filter,  
Power Led, ALC active, or de-interlacing.  
4 Click the control wheel to enter the selected settings menu.  
5 Turn the control wheel to change the setting.  
6 Click the control wheel to confirm the change.  
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.  
User manual MIVD 1218  
22  
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:  
User manual MIVD 1218  
23  
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.  
3.8. Advanced settings  
To change the advanced settings:  
1 Turn the control wheel to display the Advanced Settings menu.  
***MAIN MENU****  
Adv. settings  
2 Click the control wheel to enter the menu.  
3 Turn the control wheel to select one of the categories: CAL

6 Click the control wheel to confirm the change.  
CAL options  
Here you can change parameters for phase and level calibration  
User manual MIVD 1218  
24  
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  
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.  
User manual MIVD 1218

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.
