synergism :
So far I've only came up on this solution:
1. open device manager
2. in "System devices" find "ACPI lid"
3. Open "ACPI lid" properties, and go to "Driver" tab.
4. Select "Update driver"
5. Choose "Browse my computer for driver software" and "Let me pick.."
uncheck "Show compatible hardware"
6. And now...in "Manufacturer" select "(Standard system devices)" and model:
"Volume manager" (yes, "Volume manager")
Is there another way I can do this without having to change drivers?
I doubt drivers will help in this case.
I really don't see why you don't want the desktop to shift to the other monitor... Can't you just change the closing of the lid to make it go dark?
If you're not using your computer but want it to be ready for use, you can just put it to sleep mode. Or just shut the monitor off if you don't want the desktop to show when the lid is closed...
