I have a Windows 8.1 laptop with Intel HD graphics and three displays: 1) The laptop, 2) mini HDMI connection to external monitor, 3) USB3 video adapter connected via HDMI to external monitor. All three displays work normally except... Sometimes I seem to type a special key combination that makes the next number that I type move the active window application to the display with the corresponding index. i.e. hitting a 2 moves the current application to the second display. A 3 moves to third etc.

I cannot figure this key combination out or where to turn it off. It's driving me nuts!!!

    Honestly, Your description of the problem isn't clear enough. I know of non Windows command that would be left enabled, after being pressed, that would continue to change the display of the active application window. – Ramhound Apr 8 '15 at 16:14

    I don't believe Windows has in inbuilt shortcut like you're describing, so it's probably a 3rd party utility. Reboot in Safe Mode, and/or disable all non-MS start-ups and services, and see if the problem stops. – Ƭᴇcʜιᴇ007 Apr 8 '15 at 16:18

    I agree with @Techie007, this will be a third party application. Most laptops come with pre-installed applications that do this sort of thing. What is the make/model of your laptop? – Patrick Apr 8 '15 at 16:23

Users on this post reported the same problem, so check to see if you are running "Super Utility":

Keyboard shortcut to move a window between two monitors instead of drag and drop.

I had a similar issue. A window would jump to a different monitor as I typed unexpectedly. The issue started shortly after I installed a "J5 Create" USB 3.0 VGA adapter, model JUA310. Their software installed "Super Utility". It assigned three hotkeys for the three monitors to move the active window to a different monitor, Ctrl+1, Ctrl+2, and Ctrl+3. I resolved the issue by disabling the hotkeys via the "Super Utility". Here is a procedure.

In the Windows 7 tray, right click on "Super Utility" and select "Multi-Display Control Panel". The "Multi-Display Control Panel" is displayed. Select the "Disable" button. Select the "Save/Exit" button.

  • I think you may have cracked it. I am also using a J5 Create USB 3.0 VGA adapter. I don't have the Super Utility installed, just the driver. But that might be part of my problem also. Will report when this resolved. Thanks! – narmaps Apr 8 '15 at 17:24
  • Updated the J5 Create driver from version 14.x to the latest version 15.01.0128 and have not experienced the problem again. I did not install the Super Utility software. – narmaps Apr 11 '15 at 21:29
