1.Mounting Brackets
This line of Monitech Product has Mounting brackets that you will
attach onto the side of our monitor by unscrewing the screws on
the side and placing the brackets on by screwing in the screws that
you just removed. These brackets help you mount the monitor to
the old CRT frame of your application.
Take the set of
brackets out of the
monitor box. The
mounting ears should
be towards the back
of the monitor.
Use a screwdriver to
unscrew the screws
on the side of the
monitor.
Place the brackets
where the slots are.
Use the screws
previously taken off to
fasten the brackets.

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 am 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 high-
power devices or cables. Ensure all cables are securely
seated and free of damage.
