M|Connect Troubleshooting Guide

Screen Blinks

Question 1: Do the windows on the blinking screen move to the other screen after a blink?
1. If the windows do NOT move to another screen it is an indicator that the monitor is losing sync with the video output of the
M|Connect. This can be caused by long, or poor quality, video cables. Poor quality cables can cause:
a. Signal Degradation
b. Video Flicker
c. Video Distortion
2. Try swapping the cable with a different cable to see if it resolves the issue. If there is an adapter in use, or if the cable has a
built-in adapter (ex. HDMI to DVI), it is recommended that it be an Active adapter.

Only One External Monitor Is Working

Question 1: Are the cables to the blank monitor fully inserted?
1. Check to make sure the power cable is plugged into the power outlet and the correct input in the monitor.
2. Check to make sure the video cable is fully seated in the M|Connect dock and in the monitor.
Question 2: Is the input properly set on the blank monitor?
1. The method for selecting the input source is different for each make and model of monitor, and can usually be accomplished
by pressing the menu button on the monitor and scrolling through the menus until an option for Input, or Source, is located
and set.

No Network Connection

Question 1: Are the lights where the network cable is plugged into the dock blinking?
1. Check to see that the green and amber lights on the dock are active. This indicates a good connection to the network and
that the dock can send and receive signals.
2. If the lights are not as described in step one, check that the cable running to the dock is in good condition and fully seated
into the ports. Next check that the source for the network connection is working properly. This typically requires tools that
an IT department will have on hand.
3. If the network connection is good, and cables are good, try power cycling the dock. If the connection is still not working
replace the dock.

USB Device Not Working

Question 1: Does the device work when plugged directly into the computer?
1. Try plugging the device into other ports, directly into the computer, or other computers to determine that the device is
working properly.
2. Next try plugging a device that is known to function properly into the suspect USB port.
3. If the no devices work in one specific port power cycle the M|Connect. If that does not solve the issue the M|Connect must
be replaced.
Paintbrush Affect From Mouse Cursor
Question 1: Does moving the mouse cursor across the screen result in the graphics becoming distorted ?
1. Follow the instructions for updating drivers in the section about error messages when installing DisplayLink software.
