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...

obviously no solution until now.

there may be some improvements with the creative update this spring from what I read in the insider blog.

This doesn't solve the issue if you have a 4K monitor set at resolution of 3840x2160.

All the windows move to top left and adapt in a rectangle of 1600x1200 resolution, portion of full desktop.

any other ideas ?

"The convenience of 1x27" and 2x23" monitors will be a huge upgrade for my productivity" I thought... Couldn't be more wrong than that... Instead I have to - rearrange all my windows whenever I wake my tower up! Just putting it out there @Microsoft.

@Community - what's the registry path for win 10 so I can modify these files? I don't seem to be able to find it here. Thanks!

Only for the logbook, I have the same problem with my new 34" LG widescreen monitor. The windows are reduced and rearranged in the upper left corner after return from standby. The registry fixes, that are posted in this tread changed nothing unfortunately. Would be really great, if MS could fix this issue, even because it exists since 5 years now and I think more and more people will buy larger Screens.
