Using the LCD Display
Setting the Timing Mode
Setting the timing mode on the PC is important for maximizing the quality of the screen
image and minimizing eye strain. The timing mode consists of the resolution (example
1280 x 1024) and refresh rate (or vertical frequency; example 75 Hz). After setting the
timing mode, use the controls to adjust the screen image.
For the best picture quality set your LCD display timing mode to: VESA 1600 x 1200 @
60Hz.
To set the Timing Mode:
1 Set the resolution: Right-click on the Windows desktop > Properties > Settings
> set the resolution.
2 Set the refresh rate: See your graphic card's user guide for instructions.
WARNING: Do not set the graphics card in your computer to exceed the maximum re-
fresh rate of 85Hz; doing so may result in permanent damage to your LCD display.
Self-Test Feature Check (STFC)
Your monitor provides a self-test feature that allows you to check whether your monitor
is functioning properly. Make sure that PC is selected as a primary source by checking if
the source indicator LED labeled “PC” is on. If your monitor and computer are properly
connected but the monitor screen remains dark and the power indicator is blinking, run
the monitor self-test by following the steps given below:
Power Indicator
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a white box with a large blue
oval logo and an error message “CHECK SIGNAL CABLE.” in black color.
This box also appears during normal operation if the video cable becomes discon-
nected or damaged.

4. Turn off your monitor and reconnect the video cable; then turn on both your com-
puter and the monitor.
If your monitor screen remains blank after following the previous procedure, check your
video controller and computer system; your monitor is functioning properly.
User Controls
Your LCD monitor allows you to easily adjust the characteristics of the image being dis-
played. All of these adjustments are made using the control buttons on the rear of the
monitor. While you use these buttons to adjust the controls, an OSD shows you their
numeric values as they change.

OSD Functions and Adjustment
Icon Menus and
Sub-menus Function Descriptions
Brightness Changes the overall light intensity of the images being displayed.
Contrast Changes the ratio of light intensity between the brightest white and the
darkest black. If “CONTRAST” ratio is set too high, color saturation
occurs resulting in loss of details.
It works only with Analog source.
Image Lock
Note: this function should only be used if “Auto Adjustment”
does not yield satisfactory results.
Image lock is used to fine tune and get the best image by removing
noise that creates unstable images with jitters and shimmers.
It works only with Analog source.
The FINE and COARSE adjustments allow you to fine tune the image
quality of the monitor. Use “-“ and “+” buttons to set the corresponding
values to remove or minimize horizontal and vertical noise shown in
Figure A and Figure B respectively.

Icon Menus and
Sub-menus Function Descriptions
Although “Auto Adjustment” automatically finds the optimum values of
FINE and COARSE parameters as well as images position, it may be
necessary for you to adjust those parameters manually. It is recom-
mended for you to use “Auto Adjustment” first. If the adjustment results
are not satisfactory, then use COARSE and FINE adjustment features
to get the best adjustment results. Bear in mind that COARSE and
FINE adjustments may change the width and affect image position as
well. If the image is clear while out of center by a couple pixels, use
image position to center the image.

Image Size Note: this function should only be used if “Auto Adjustment”
does not yield satisfactory results.
Aspect ratio is the proportion of vertical versus horizontal resolution,
and it varies depending on the video resolution. For example 640x480,
800x600 and 1024x768 have the aspect ratio of 4:3, and 1280x1024
has the aspect ratio of 5:4. To view original image without geometrical
distortion, aspect ratio must be preserved.
!Expand 1 Performs full screen image expansion regardless of the aspect ratio of
the input video resolution
!Expand 2 Performs image expansion while keeping the aspect ratio of the original
video resolution. Usually there will be some unfilled space to the hori-
zon direction.
!Normal Performs no image expansion. In this mode, input video is displayed at
the center of the monitor as is.
RECALL Discards current setting and replaces corresponding parameters with
the factory default values.

Installation Instructions
Preparing for Installation
Important! Perform the following steps BEFORE Installation of the monitor into the panel.
1. Ensure that sufficient power is available.
2. Ensure that sufficient space is available to allow for proper airflow into and out of the unit.
3. Ensure that the air temperature around the unit (top and bottom) will not exceed the rated specifi-
cations of the unit.
"The maximum rated temperature of the HIS-ML21 is 50
° C (122 ° F) with the fan kit
installed and with use of an equally rated power supply.
"Remember that heat rises – the temperature at the top of the cabinet will be much
hotter than at the bottom when the air is not circulating.
"Also, remember that even though this product is designed to operate at 50
° C with
proper ventilation, the life span of any electronic device is shortened when it is
consistently operated at high temperatures. Therefore it is wise to take steps to
keep the temperature of the ambient air around the unit as low as possible.
4. Ensure that the ambient humidity of the air around the unit does not exceed the rated specifica-
tions for the unit
"The maximum rated humidity for the HIS-ML21 is 80% non-condensing
13

Installation into Panel
1. Refer to the drawing above.
2. Locate position in panel for mounting of the monitor. Assure that there is
adequate space begin the panel. Allow extra space (0.5 in. behind and on
each side) for air ventilation.
3. Cut a rectangular hole in the panel. Clean and deburr.
Dimensions: 21.13” (536mm) W x 16.70” (424mm) H ; +/- .020”
4. Separate the rear collar from the unit by removing the 14 nuts.
5. Insert the unit into the front of the panel and re-attach the collar.
6. Tighten all 14 nuts to a torque of 24 inch-pounds to assure a water-tight seal between the poron bezel
gasket on the monitor and equipment panel. HIS will not assume liability for damage to internal elec-
tronics due to improper installation.
Cleaning
Any standard glass cleaner can be used to clean the touchscreen or pro-
tective safety glass window. Always spray the glass cleaner on the cloth or
towel and then clean the touchscreen. Glass cleaner sprayed directly on
the monitor could possibly leak inside a non-sealed unit and cause dam-
age.
Vinegar or ammonia will not hurt the touchscreen. Again, spray the cloth and
then clean the touchscreen.
