Turning off display freezes "underlying display"
I don't know where to start with this problem - if this is not the right section please redirect me. I record certain wildlife webcams 24/7 and extract "events" to upload to YouTube "for the record" and share with other interested parties.
At times I want to switch off the display so's not to give out light and to save power, but need to keep recording. This works fine on Dell Precision M4400 Windows 7 Professional 64-bit, but on Dell Alienware M11x-R1 and M11x-R3, both running Windows 7 Home Premium 64-bit, all I get on completed recordings is a still picture of whatever was onscreen when the display was switched off.
This happens whether I use ControlPanel/PowerOptions settings to turn the display off after so many minutes, or use a keyboard shortcut created with NirCmd (to save disturbing the recording by opening ControlPanel).
As said, I just don't know where to start to figure out why the behaviours are different on the 3 laptops and would be very grateful for guidance.
