Windows 7 moves/resizes windows on monitor power cycle

Anonymous

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...

What I can see on the system here, where I use to different monitors, makes me think there is a fat bug somewhere. Under ..\GraphicDrivers\Configuration my system lists 46 different entries for the next level, some having sublevels 00,01,02 under 00...

Uh ... no. On reboot, not only was everything "crammed" in the upper reaches of the desktop, but also all of my desktop icons were rearranged and stuffed into the upper left corner. So, I'm hoping that MichaelAtOz or some other person (who obviously is far more tech-savvy than I am) can find or figure out a solution that works and holds on even through a shutdown and hard boot. And I'd be very grateful for it. Enjoy the challenge!

My OS (W7) and monitor (Acer) never had a resizing problem until a recent Microsoft "update" (Right. Go figure, yeah?). I've been fighting this resizing thing ever since. I read and used MichaelAtOz's post to try to correct it, which for some reason was ineffective. Then I got to thinking about what creates the simulated key lines and considered, "Might completely resetting the resolution via the Control Panel > Display > Adjust resolution have any effect?" Okay, I've now taken it down to 1600 x 900 and applied it; then I took it back up to the recommended 1920 x 1080 and applied that. Okay, so far: turning monitor power off is not causing the windows that are open on the desktop to resize as they had before I did that. I'm going to post this first, then will hard boot (shut down completely and restart the computer from the power button). I'll let you know what happens.
