Can I use multiple FL2000 adapters to add more monitors to my system?

No, most system can only support one FL2000 based USB video adapter.   Keep reading if you want the details.

Multiple FL2000s on one system is not officially supported.  If you open a support request for help with it, you will get a link to this article but no further support.


The FL2000 USB to Video adapter needs a lot of data to keep working properly.  Most computer systems aren't able to send enough data over USB 3.0 for two FL2000 adapters.  This means that one or both monitors will start flickering or go completely blank.

Still want to try it?  Here are some rules to give you the best chance.
  1. No Hubs!  USB hubs provide more ports but can't increase the amount of data a USB port can send.
  2. If your system has more than one USB 3.0 Host controller, connect one FL2000 to each controller.  You can also try adding an additional PCIe to USB 3.0 adapter card to your system.
  3. Lowering the resolution of the monitors also lowers the amount of data needed.
  4. Change the Windows Power Plan to "High Performance".  Modern computers try very hard to save power.  Sometimes they try too hard and this can effect how much data they can send over USB.
