Win 7 64 Forgets Multiple Monitor Config On Reboot

sexinxs · 12-05-2010, 11:48 PM

After I installed 5.5M1 in a multi-card, multi-monitor eviroment (I know it's not supported, but it worked perfectly since this rlease) composed by:

- 3 Asus Nvidia GTX580 (SLI or non-SLI no differcence)
++ 2 Display @ 1920x1200 on first card
++ 1 Display @ 1920x1200 on second card
++ 1 Display @ 1920x1200 on third card
- 1 Asus Nvida GTX480 (PhysX dedicated)
++ No Display connected

Windows 7 64 started to forget multiple monitor configuration and resolutions on reboot: one of the 4 displays goes off after login, another one is on top of the primary and another one sets wrong resolution... It's stuck in that configuration, doesn't matter if I correct it through Windows display properties or Nvidia Control Panel...

The real issue is that also competely uninstalling DisplayLink's drivers (I used also the DisplayLink Install Cleaner) the problem persists!!!

The problem doesn't occour in simple log-off and login sequence, but just on reboot or after a shutdown.

It seems like Win 7 can't recall multimonitor configuration (nor positions, resolutions nor on/off state) during boot... or, really, it can rememeber just ONE (wrong) CONFIGURATION...

Checked boot sequence programs (msconfig) and run keys in registry... everiyhing is ok..

If I manually delete display's entries in registry under
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\GraphicsDrivers\Configuration] & [Connectivity] it rebuilds them correctly after I set up display configuration (windows display panel and Nvidia control panel have same effect) but after a reboot a new entry shows up with the messed up configuration...

Any ideas??

Sorry for my poor technical english...
