so i had this issue with the latest update 2.1 that is one of the monitors remains blank i tried every possible way and at last i got it fixed .
here is how
- i have 2 displaylink USB - DVI .
- i bought one DVI-VGA adapter
- connected it to one of the display link
- connect the other end to my VGA port in the screen.
- installed 2.1 .
now it's working like without even a lag issue
