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...

This has been a problem going back to Windows 7 so anyone here who thinks Microsoft is go to fix this is fooling them themselves. I sent feedback about this issue in the Windows 10 feedback app but I will be shocked if this gets fixed anytime soon or at all in Windows 10

I mean I have not even seen anyone from Microsoft here talking about this issue :(

Users should not have to mess with the windows registry to fix this issue!

It's very disappointing!

Hello grml,

Due to the age of this thread, you woud be better served by creating a new thread for this issue.

There will most likely be subtle differences between this issue and the one in this thread.

Hi Michael,

If I understand this correctly, your computer is changing the resolution for the monitor after it wakes up or you turn it off then on again.

I found this in a review for the TV:

" The ... LCD has a native resolution of 1680 x 1050"

What happens when the resolution is set to 1680 x 1050?
