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...

    Was hoping I could do this but my Nvidia control panel lacks the workstation node.  It simply isn't there. I see others with similar problem but there is no way to bring that node back so I can export EDID

    I tried Ruahmina's method, but that didn't work for me. I have an NVIDIA card. I found this solution:

    http://superuser.com/a/631691

    which refers to these instructions:

    https://sites.google.com/site/ebobster/stuff/displayportblanking

    Step 4 is a little ambiguous as to how exactly to export and load it back in. I won't give steps here, as the Nvidia Control Panel changes frequently.

    However, when I exported the EDID information to a file, IT FIXED THE PROBLEM! My computer actually doesn't even register when I turn off my TV now (which is fine by me).

    Just wanted to share since there is a lot of frustration out there. While this solution only works for Nvidia, I am sure there is a way to export/load the EDID for other cards that can be found through a bit of googling.

    Hi!

    I've had this issue before and the registry changes fixed it fine. However, after i installed win 10 1511 yesterday the problem returned. I tried deleting all keys under config but after turning monitor off and on again only the monitors key is shown. Simulated monitor key doesn't appear. Anyone know anything about this?

    I'm Currently Using 1 4K monitor via displayport, 2 others on dvi and a TV on HDMI. Your Solution worked the first time I turned on the monitor after I changed the registry and rebooted.  After that, it did not work for the second time and so on.
