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...

BUT after the latest Windows 10 major update (1511) I am no longer experiencing this issue. Did they fix it? Is this a coincidence? Will it happen again tomorrow? I don't know, but I will keep this post updated.

This fixed it for me too! Windows 10 1511 (build 10586), also known as the November Refresh fixed the window resizing on my laptop.

This seems that it must be a fundamentally different problem from what the users with external monitors are experiencing.

For a moment, I also thought that it was fixed in Windows 10 1511 (build 10586).

But it wasn't.

How can Microsoft advertise that this latest release is ready for large-scale business use? Do they think everyone uses 1920x1080 laptops?

Just to add some thoughts

When a computer sleeps or restarts, something has to save window positions in persistent storage.

On a clean machine, something has to learn the dimensions of a newly connected screen.

I have the problem on two separate systems, one DVI, one DP. One Intel HD3000, one Intel HD4000 embedded graphics.

Contributors to this forum seem to use many different combinations of graphics cards, drivers and cabling.

The common element seems to be Windows.

I tried updating to Windows 10 1511, but unfortunately no luck for me

By the way I am connecting using Geforce 760GTX and a Display Port. Frustrating - hopefully some guys in MS have a similar config!

All the best,

Ash
