Multiple UGA-125 Adapters

I am having problems running 3 monitors on my Windows 7 pc. I am running 1 off of the video card, 1 via a Plugable UGA-125 USB 2.0 adapter and can’t get the 3rd monitor to run off a 2nd Plugable UGA-125 adapter.

Is it possible to use 2 adapters to add 2 monitors to a system?



Hi Rob,

Thanks for posting! I am sorry to know that you are having trouble getting the third monitor to display when connected to the Plugable UGA-125.

Connecting multiple monitors through multiple units of our USB 2.0 Graphics Adapters is very common. So it is definitely possible to use 2 adapters to add 2 monitors.

Could you give us some more information regarding your setup so that we understand why you are unable to connect the the third monitor using the 2nd Plugable UGA-125?

Are the Plugable UGA-125 connected directly to the inbuilt USB ports of the system or are they connected through a Hub?

Is the OS reporting any errors when you plug in the 2nd Plugable UGA-125?

Does the Green LED get lit on both the units of the Plugable UGA-125?

Once you post back with this information, we will figure out the next steps.


Its working now…thanks
