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...

    I was replying to PiRh0's problem about the 2560x1600 window size. The problem seems to be specific to NVIDIA on ultra high definition displays. Editing NV_Modes fixed the problem for me.

    Hiturpojurpo,

    sorry I did not write that this error occurs with the Intel on-board graphic.

    Currently I am using Intel HD-Graphicsdriver 9.17.10.4229 and an ASUS ProArt Monitor with a maximum resolution of 1920x1080.

    The strange thing is that everything worked fine until end 2014 - so either an Intel or a Microsoft update caused the trouble.

    TGiF,

    Winfrid

    2560x1600 is the maximum resolution defined in NVIDIA's "common modes" list. The NVIDIA driver presumably looks at this list for a safe fallback mode. The list can be found in the registry if you search for a value called NV_Modes. Its content should look like this:

    {*}S 720x480x8,16,32,64=1; 720x576x8,16,32,64=8032;SHV 1280x720x8,16,32,64 1680x1050x8,16,32,64 1920x1080x8,16,32,64 2048x1536x8,16,32,64=1; 1920x1440x8,16,32,64=1F; 640x480x8,16,32,64 800x600x8,16,32,64 1024x768x8,16,32,64=1FFF; 1920x1200x8,16,32,64=3F; 1600x900x8,16,32,64=3FF; 2560x1440x8,16,32,64 2560x1600x8,16,32,64=7B; 1600x1024x8,16,32,64 1600x1200x8,16,32,64=7F;

     1280x768x8,16,32,64 1280x800x8,16,32,64 1280x960x8,16,32,64 1280x1024x8,16,32,64 1360x768x8,16,32,64 1366x768x8,16,32,64=7FF; 1152x864x8,16,32,64=FFF;

    There, you can replace 2560x1600 with 3840x2160 (without touching anything else) thus making it the new maximum "common" resolution. Restart Windows after the modification. This has worked for me. Good luck.

    Many thanks, your hint with the "regedit" seems to work.

    Nevertheless I think that the problem was introduced by some Microsoft(?) update, because it happened to me the first time end of 2014, so about 2 years after I purchased my computer.

    Note - my computer is always up-to-date with Microsoft updates.

    Update for Windows 10 -

    editing the registry does not work for Windows 10 !!
