I have a Dell laptop with a docking station and a Gateway EV910 monitor
attached. Normally I have the laptop screen as primary and only turn on the extra monitor if I need extra space.

Most of the time it works fine, but sometimes if I just close the lid for the night, when I open it there is no display. If I turn on the secondary display I find my desktop. That's happened now and I cannot get the primary display back to my laptop.

Yes, I can, by doing a system restore to a couple of days ago, it worked fine, but I have added AVG and don't want to have to re-download. When I go to Display>Properties>Settings, and click on the Secondary icon, I get a popup window that says "Secondary Display (1600, 200), not a chance to check 'Use this device as the primary monitor' as documented in a Microsoft document I found through Help and Support. Anyone understand multiple display support who's willing to help? It sure would be appreciated.

I realize it wouldn't be a real big deal to restore and download AVG again, but I really think there is a way to do this without backing up, I just don't know where to find it.

Thanks, Stan

Open your power options properties and change them from Portable/Laptop to Home/Office Desk, see if that will help. Sounds like when you shut your lid it is going into standby mode.

Bud, you're a real whiz. I would not have come up with that in a million years.

I had the cable disconnected from the extra monitor as a work-around since I don't use it much. When I read your response I hooked up the monitor and turned it on, then did a restart and came up with the primary still on the laptop screen like I want it.

I'm confused as to why my original fix worked. System restore to two days ago=everything fine. Undo restore=broken again. Is the power setting saved somewhere outside Windows? Do you know if there's a tutorial that will teach me what's going on in multiple display support?

I'm happy as a hog in spit now, but sure curious too.

Thanks again,
Stan
