Windows 7 moves/resizes windows on monitor power cycle

I have a new W7 ultimate install on a new PC (AOpen DEX4501 w intel GM45 graphics). I have installed the latest Intel graphics drivers 8.15.10.2202, and all relevant windows updates.

It is connected via HDMI to a Grundig Misuro HD TV. My resolution is set to 1600x900, windows recommended resolution is 1920x1080 but this displays badly so I don't use it.

When Windows sleeps, or I turn off (then later on) the monitor, most windows are moved/resized to the upper left with the lower right at 1024x768.

Firefox, Excel(2003),Explorer windows resize/move, Outlook(2003) did not move/resize.

I have a Samurize (Gadget like) display on the right which someimes get relocated to the top left, but not this morning. The windows resize/move also happens when Samurize is not running.

I have found three other entries related to this;

They don't seem to have been resolved for a long time.

This is a Windows monitor power managment issue, can it be fixed please it is very annoying.

I won't be recommending W7 to others with such issues outstanding.

I have found a work-around.

Using Sysinternals ProcessMonitor I found that Windows was accessing the following Registry path;

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration

My system had three entries;

DELF003YY7707BR0MUL_30_07D7_6A^9A3774EB79DEE3E3E38496CC7DF4D936

QHD32000001_31_07D6_D5^63E1ABDD175E7871DCAEB710418A0F75

SIMULATED_8086_2A42_00000000_00020000_1010100^CDE365D1B3F0942F0CF38BFB8E127AB4

Under each is a tree called "00" two of the keys are

PrimSurfSize.cx

PrimSurfSize.cy

Under "00" was another branch also called "00" two of the keys are;

ActiveSize.cx

ActiveSize.cy

The first two of the configs (ie DELF00... & QHD3...) the above keys were 1440x900,

so they were not involved.

The third (SIMULATED...) were set to 1024x768.

I changed these to 1600x900 and the problem was solved.

Further I changed resolution (via control panel) to 1920x1080, the moving/resize issue returned,

but the lower right corner was set to 1600x900, ie the SIMULATED... settings.

So for some reason one of the configs does not get set correctly.

I don't know why there are three configs, I have only ever used one monitor.

Hope this helps someone out there...

    After monitor is powered off and back on, all non-maximized windows, whether on screen or minimized, are resized smaller and placed in the upper left corner of the screen.

    First ran into problem on my new machine: Windows 8.1 64 bit, GeForce GTX970, Asus PB287Q at 3840x2160, DisplayPort 1.2.

    Behaves the same regardless of windows scaling setting (I've tried 100% and 125%).

    Upgraded to Windows 10 Pro, behaves the same.  I've messed with the registry keys, as suggested.  No effect. 

    I never saw this issue on my previous machine (Win 7, Samsung 2343 at 2048x1152).

    Apparently this has been happening for at least 6 years, so it is not dependent upon Windows version.

    It seems as though Microsoft blames the graphics drivers for this problem.

    Since it happens with various monitors, graphics cards, and Windows versions, it would seem to be a Windows environmental problem.

    Anyone have any ideas??

    My God! That's fantastic, albeit hilarious. I wrestled with this for days to no avail. You solution works perfectly. How ever did you come up with it? It's hilarious to connect a graphics card to a monitor via DisplayPort and HDMI just to make the DisplayPort work properly! This workaround should be much better known.

    Thanks!

    Well, I just figured if my "dog" chewed through his leash and ran off to roll in the mud every time I took a nap, I could either spend a lot of time trying to figure out how to tie a stronger knot or just tie on a second leash.  Hopefully, one day Microsoft or NVidia will fix the "knot," but for now a second leash works for me ...

    I did these changes, and I also changed DwmClipBox settings, rebooted Windows 10, but no luck.
