I have a workstation with two monitors and the desktop extended over them. I have a lot of applications open (generally maximized), and I have a personal preference which application is on which monitor (let's say editors on the right, data retrieval and display on the left).

I have recently upgraded to a workstation with Windows 7 and when I power off a monitor (typically when going home at the end of the day), the desktop-expand-over-monitors disables and all applications are switched to the main monitor. (Also the taskbar I keep on the left resizes to about one icon's width.)

This is highly annoying, since I now spend the first minutes of work each day switching the applications back that were on the monitor on the right.

Is there a way to prevent this? (It says no here.) Is there software I could install that can prevent this?

An alternative is setting the default resolution in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration

Under this location you will find all the monitors you had attached and their configuration plus two additional: On starting with "NOEDID" and one starting with "SIMULATED".

Both entries have a sub-key named "00" and inside the two values PrimSurfSize.cx and PrimSurfSize.cy specifying the resolution - by default 1024 and 768.

Change them to your monitors resolution. That should fix the problem.

In the case with my NVIDIA NVS 310, apparently you can 'force' an EDID on a DisplayPort.

  • Open the NVIDIA Control Panel (from the desktop context menu)
  • Select Workstation, View system topology
  • Next to DisplayPort (1) and (2), there's a link EDID
  • On each DisplayPort, first do Export EDID, then Load EDID

The first time there's a warning about possible damage to monitors when you get EDID's mixed up, which may not be covered by the warranty on the monitor. So don't get the EDID's mixed up!
