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...

Windows 8.1 Pro x64, Sapphire Radeon R7 260X graphics with the latest 14.9 driver, dual-link DVI (only connection on the monitor), 2560x1440@60Hz "Korea" ACHIEVA Shimian QH2700-IPSMS Lite Edge II 27" IPS monitor, brand-new everything, and I am having exactly the same very annoying problem with the monitor device being removed when it goes to sleep and then reconnects when it wakes up with the windows shrunk and pushed into the upper left corner.

Where are you Microsoft tech support? Any plan to issue a hotfix for this problem so that the monitor device isn't removed when it goes to sleep?

This is happening to me as well with Windows 7 Ultimate and my new ASUS PB287Q (4K @ 60Hz). All windows are re sized to what looks like 1920x1080 and shoved to the top left corner when the monitor goes to sleep, and when I simply turn it on and off again.

It's unfortunate that I will be returning the monitor because of this issue. As a person that leaves lots of windows open and lets the monitor go to sleep, it's unbearable dealing with this issue multiple times/day.

Probably none of those will help at all. The real fix is to change the values of the registry entries as MichaelAtOz's post's earlier in this thread suggested. The same issue happened to me with Windows 8 x64 as well, and doing the registry edits definitely solved the re-sizing of the windows at the very least. Look over my earlier post in this thread as well, where I give more details.

This only seems to be a problem with monitors with resolutions larger than 1080p AFAIK.
