Lenovo B590 and UD-3900 - Out of Box Questions

[Bob Vance]

Thanks. In regards to my graphics card issue, I have a single monitor connected. I only have "notebook monitor off" applied. Maybe this explains why I cant change display settings thru graphics card? I erred earlier. I can access the card. I cant make any modifications to the card's settings. Do I need to "set as main monitor" and/ or "extend" or "mirror" to let my card work on my USB connected monitor?

Also, how will I know when updates are available if the connection has been disabled? Why does it offer check for updates if it won't?

One last question: I read this on plugable forum "we generally don't recommend using the laptop in 'lid closed' setting with our docking stations, as there is some system dependent behavior that can complicate matters." I've been doing this since day 1. Could this be the issue with my card?

Thanks
