Running the laptop screen simultaneously
Computer starts normally and generally runs normally. But if I open Powerpoint or the "Windows Settings" app, I get very strange behavior. I'll use the word "focus" to indicate what happens when you click on a window: you changed the focus to that window. If the offending program is on my laptop screen and I click on it to change focus, or click elsewhere to change focus from it to another app, behavior is fine. But if the offending program's window is on my flat screen, changing focus to or from that program causes the screen to flicker: it blacks out and returns immediately.
Other programs, including Word, Excel, Mozilla, Chrome, and Notepad++, no problem. No flicker, behavior normal and as expected.
I'm thinking that its a driver issue, as I'm using the nvidia driver and not the older lenovo driver. Does the ultrabay have BIOS that can be upgraded? Is there an ultrabay driver? I suspect that its the nvidia driver. Anyone else ever experience this?
