ProBook Screen Resolution Issues - switches between single display and dual screen?

[tbroyles]

This is a problem I have been having for several months, even though I've only had this computer for a little over a year.

The screen will go black, it makes the same noise as when I plug in a USB or HDMI, and then the display comes back. That process happens pretty quick, and sometimes it happens MANY times in a row, which is very annoying, or it'll happen just once or twice. The applications on my screen might move around a bit as they readjust or whatever it is that happens. I have found little rhyme or reason to when this happens. Sometimes it happens when I am doing nothing to the computer, like watching a video, not touching anything, or if the lid is open and the screen is still on, but I have left my computer. But I can pretty dependably get it to happen when I move my laptop (adjust the lid angle, shift it on my desk, etc.), carry it while the lid is open, or put it down.

When it was still under warranty, I took it to Microcenter, where it was bought, and they couldn't find much wrong with it. I think they updated some drivers is all.

Recently, I noticed that sometimes I am able to put my mouse off screen to the right, as if I have another screen connected. But then it will do the weird display blackening, and then I wouldn't be able to move the mouse off screen. This got me thinking that there is an issue with the screen resolution and that it frequently thinks I am connecting a screen. I even have some videos I took to support this; I can't figure out how to attach a video, so I will attach some screenshots from the video to show what I mean. My laptop definitely is going between thinking there is a single display to more than 1.

Any thoughts on how to fix this? Or who to contact about it? It is awfully annoying.
