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...

    This fixed my issue on a Samsung S34E790C (ultra wide) that runs on 3440x1440 resolution on a GTX 970. All windows got squeezed into the upper left corner when the screen slept, was turned off, games changed resolution..  you name it.  Windows 10 btw.

    Looks quite the same as mine, except that there is no

    BNQ....\00\00 , I just have "BNQ...\00"

    (But on my first try I had also some extras - more than one "AC123B....")

    In the meantime I succeeded also on Windows 10 -

    it worked for me on the second try.

    I deleted all monitor entries in the registry (GraphicsDrivers)

    after this I switched of my monitor (wait some time) and switch the monitor on.

    After this I got in GraphicsDrivers\Configuration 2 entries

    AC123B1.... (my ASUS ProArt ...)       and

    SIMULATED...

    please check that you have the correct values for PrimSurfSize.cx , PrimSurfSize.cy and Stride.

    For SIMUTED...\00\00 I also adjusted  ActiveSize.cx and ActiveSize.cy

    Could you please take a look at these screenshots and let me know if I did anything differently than you? I'm also on Win 10 and did exactly what you did, deleted the monitor entries, changed Simulated entry to be same as the active monitor. I'm not having any luck though. Doesn't change behavior for me.
