Extended screen issue

Hi, My laptop(Windows7) add another extended monitor. When I have two monitors, everything is fine. But when I disconnect the additional monitor, I cannot see some windows which was located in the extended monitor
Any one have some idea to solve this issue ?

Have you tried Windows+P key a few times to disable the external display explicitly?

Happens all the time to me. Here's what I do:

(1) Click the app's icon on the taskbar to select it.

(2) Hit Alt-Spacebar to get the control menu for that window (of course, you won't see the menu, but it's active):

Alt-Spacebar menu
(3) Hit the M key to invoke Move, then lean on the left or right arrow key to move it onto the visible monitor, and once you see it, grab the title bar with your mouse and position it wherever you want.

(4) If it is maximized after Step 2, then Step 3 (the M key to move it) won't work. You need to de-maximize it first by hitting the R key (Restore). Then do Step 2 again and this time Step 3 will work.

Sounds more complicated than it is, and after a few times at it, you'll become a pro. :)  Regards, Joe

You can also use the windows key + left arrow key  or windows key +  right arrow key. IT will move the application to the current screen.

> But another Laptop does not have this issue.

Hmmm, don't know what to say. I've had it happen on many laptops during many years with many versions of Windows. My personal experience (and that's all it is — my personal experience) is that it's dependent on the app and not Windows. Some apps are fine when I run them on the laptop while travelling (they come up on the laptop screen), while other apps come up in what I call display never-never land — on the non-existent monitor. I've taken the highly pragmatic approach of moving them to the laptop screen whenever it happens. But I'll keep my eye on this thread — will be interesting to see if anyone knows of a one-time, permanent fix.

Btw, I'm very curious that it happens on one laptop and not another. Are you sure about that? Can you experiment with an app that opens in display never-never land on one laptop and then try that same app on the other laptop? Thanks, Joe

Just right-click on the desktop, choose Graphic Properties and change the Display Settings to a Single Monitor or...
"Start/Control Panel/Appearance and Personalization/Personalization/Display Settings" and change settings to a Single Monitor.

The laptop that is having the issue:

- does it have any virtual desktop application installed?
- did the issue just appear or did it never work?
- are the latest video drivers installed?
- is it the exact same model as the others?
- setup / installation anyway different?
