I have a Dell Vostro 3500, Windows 7 32 bit system. I am running one monitor through my laptop, and one monitor through my plugable USB 3.0 dock. I can’t get the system to recongize the monitor plugged into the docking station.
Thanks for posting your question here! I’m sorry to know that the monitor connected via the graphics port of the Plugable UD-3000 is not detected by the system.
As a sanity check, please make sure that all the connections between the graphics port of the Plugable UD-3000 and the monitor are tight enough and that the correct input mode (VGA, DVI or HDMI) is selected on the monitor. Once that is done, power cycle the Plugable UD-3000 by unplugging and replugging the power adapter to reset the Dock.
If the external monitor is still not detected by the OS, please do post back with the following information:
What is the make and model of the monitor connected to the graphics port on the Plugable UD-3000 and is it connected via VGA, DVI or HDMI?
How long is the cable connecting the graphics port to the monitor?
If you swap the monitor connected via the inbuilt video output port on the system with the monitor connected via the graphics port on the Plugable UD-3000 does Windows 7 detect both monitors?
Do all the other ports on the Plugable UD-3000 work without issues?
If you connect the Plugable UD-3000 to a different USB port on the system, does the issue persist?
Once you post back with this information, we will figure out the next steps.
