7

I have a Fujitsu P772 notebook computer. It came installed with Windows 7 and I recently upgraded to Windows 10. After the upgrade, I noticed a problem whenever the screen would go to sleep by the five minute inactivity timer or right away after being locked. Moving the mouse should wake up the screen, which it does, but before that happens, Windows switches to the internal screen for a second. This causes all the windows to be resized and moved to fit the smaller internal screen size (1280 x 800 vs 1920 x 1200).

Computer specs:

  • Intel Core i7-3667U
  • 4 GB ram
  • 64-bit Windows 10 Build 10240 OS
  • Intel HD Graphics 4000

So my questions are:

  1. Is there an easy way to prevent the windows from resizing when switching to the internal screen and back, or possibly to automatically restore them? (I have figured out a way to do this, but it's not so easy.)
  2. Better yet, is there a way to tell Windows to not use the internal screen at all until I tell it to?
  3. Is this problem likely the fault of Microsoft, Intel, or Fujitsu?

(My workaround for now is to use my phone to connect to my computer using remote desktop [at the 1920 x 1200 resolution] and then wake up and log into my computer.)

I have a Sony Vaio laptop with Intel HD Graphics 4000 that I did the same 7 to 10 upgrade with and was experiencing similar display issues. Earlier this week I upgraded to Windows 10 build 10525 and used the Intel driver update utility to update the graphics driver to 10.18.10.4226 (version reported in Device Manager). These were both done on the same day so I can't say which one resolved the problem but it has since gone away.

Try this:

Go to Control Panel -> Display -> Change display Settings

Select your secondary screen and tick 'Make this my main display'

Then in the "Multiple displays" box select 'Extend these displays'

That fixed weird flickering issues after sleep on my Win10 laptop, hope it works for you too.
