Just press AUTO.
Once you have mounted your new Monitech LCD into
your control panel with the video cable attached, the
indicator light on the back of the monitor may turn
green. This means the video power is on. If the green
light is off, press the I/O button to power it up.
Now press AUTO on the 6-button menu found on the
back of the LCD. After a few seconds, the screen will
center the image and automatically adjust the image
size, color, brightness and contrast.
That’s all there is to it! Your LCD is ready to go.

Fine-tuning your video image
If you would like to further adjust your image values,
use the buttons on the back of the LCD. Press MENU
and this image will appear:
Press MENU again to open the COLOR menu. To open
to the PICTURE menu, press the down arrow and
then press MENU.
Repeat this wherever you are in the menu. To open or
expand an item, press MENU. To move up or down
simply press the up or down arrows. To exit a
menu, press AUTO.
Here are more details about the menu.
COLOR
Use this menu to adjust the brightness, contrast and
color. Use “Color adjust” to change the ratios between
red, green and blue. Use “Color Temp” to set color
saturation. (If you select USER and the color gets
messed up, go to the MISC menu and select RESET.)

PICTURE
Fine-tune the image by adjusting the horizontal (H)
and vertical (V) positions as well as the phase, clock
and sharpness.
FUNCTION
Use this menu if you want to select or deselect
Auto Adjust for size or Auto Color for color
optimization.
OSD MENU
OSD stands for on-screen display. Use this menu to
choose a language other than English (our LCD
supports ten). The OSD Timer defaults to ON, meaning
that the menu will close after a few seconds of
inactivity. Select OFF if you prefer to close it manually.

MISC
Use this menu when you want to erase everything you
have done and get a fresh start. Choose RESET.
Video connector
This picture shows the value for six pins on the video
connector at the back of the monitor. (The other pins
have no application.)

Troubleshooting
My screen is black.
Ensure the DC power cable is fully inserted into the
monitor receptacle. Use only 12V 4.16a power supply
(+ on center pin). Ensure the power supply is securely
connected to a 120-240V AC power source and that
the green light indicates it is ON.
I’m seeing lines through my video.
Press the AUTO button at the back of the monitor.
How do I increase the brightness on the screen?
Press MENU, then MENU again to open the COLOR
menu. Adjust the brightness from there.
How do I deal with intermittent video issues?
Ensure the video cable does not run close to highpower devices or cables. Ensure all cables are securely
seated and free of damage.
