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