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...

Aughhh god. Just wasted about 10 minutes creating the account to write this reply because username LukeFlegg was "already taken" (by me, silly Microsoft! and I couldn't seem to use that existing log in, I had to create a new one grr)

Anyway

So I don't have any entries called 'SIMULATED' - I'm using a MSI laptop (GT72 2QE) and Acer 24" 4k monitor. EVERY time it wakes, all my Chrome windows are beyond maximised (spreading over onto laptop screen) it's getting pretty annoying now and it's surely preventable?

Windows 10.

Any help would be so appreciated! I don't know what to do - here's a a printscreen of the entries I get

Hi there, if it was me, I would delete ALL the entries under Configuration and reboot. When your laptop comes back up, you may need to go into display settings and reconfigure the way you want.

I recently made some changes that seem to have reduced the issues related to screen chaos. My Windows 10 is on fast ring preview, and the latest builds seem to be better, I also have the latest Radeon drivers, I removed one screen from the system so there is now one 3440x1440 LG and one 1440p ASUS gaming monitor. Both are in the default rotation.

Now, I can let my PC sleep without waking up to a blank disabled screen. The windows will still be moved around, but the situation is still better 'cause it's not creating a bunch of bogus configurations.

Next up, I'd like to try two Radeon 480s and see how that works. Eventually I want to get back to three screens.

I'm new to Windows10.

The idea that I can't effectively use my 3 monitors is making me rather upset. It's this sort of problem that gives MS a bad rap. As this thread is testament, it's been a bug for years. Everytime my system go to sleep, I end up having to readjust all the windows on my editing software.

Why?

No good reason as far as I can see.

Anyway, the "solution" involves doing a hack on something called the registry file. What is that and how do I even access it? It looks like a bunch of nonsense to me. Plus, there's no guarantee it works anyway.

More important, why do I have to mess with it at all? I'm a layperson not a computer scientist for goodness sake. Why should I be poking around entering strings and code into a file I don't understand?

Auuugh.
