Randomly blanking monitors


Using a 3-monitor setup with 3 UGA-2K-A adapters on a windows 7 laptop computer: the screens intermittently go blank individually, appear to drop down to 1 or 2 screens randomly, and then come back to the original 3-monitor setup but with all of the open program windows having moved to different screens depending on which order the monitors went blank. All of that happens in 2 to 5 seconds. Sometimes once a day, sometimes 2 or 3 times in 5 minutes.


Hi Cummings,

Thanks for posting here! I’m sorry to know about the issue you are seeing. The blanking of the monitors and the open windows moving is an indication of a temporary disconnect.

Some quick questions to understand the setup and the issue better:

  1. What is the make and model of the system to which all the three units are connected?

  2. How are the three units of Plugable UGA-2K-A connected to the system? Are they connected through inbuilt USB ports on the system or via a USB hub? If connected via a hub, is the hub powered?

  3. Are the units connected to the system via USB 2.0 or USB 3.0?

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