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...

I solved my problem but don't exactly know how.

Originally my DGM 24" monitor was using DVI to DisplayPort adapter and going into the DisplayPort of my graphics card.

I swapped this connection with my ASUS 27" (does have a DisplayPort connection but not used) and it now works.

So

Old setup

DGM 24" - DVI > DP

ASUS 27" - DVI > DVI

New setup

DGM 24" - DVI - DVI

ASUS 27" - DVI > DP

I've no idea, only there is definitely some bugs to be found.

I am also having this problem.

Radeon 7970, latest drivers and Windows 10.

My monitors are connected as, 1xHDMI, 1xDVI and 1xDisplayPort.

I deleted all my entries under configuration and started from fresh.

In my registry below the longer entry at the bottom is my full working config with 3 monitors listed.

DGM24 - DGM 24"

ACI24 - Asus 24"

ACI27 - Asus 27"

When my monitors went to sleep and I resumed, I refreshed the registry and found another entry but with only 2 monitors listed ACI24 + ACI27.

DGM24 was not being detected and the windows that were on it were pushed to another screen. DGM24 came back on but was like a new monitor was plugged in.

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.

Persistent Windows FTW!! I, too, have ATI/AMD graphics. I've completely uninstalled and reinstalled the drivers several times. I'm running what they claim is the latest set for Windows 10 now. Same issue. Thanks for the tip.
