Hi,
I need an application to let the display go into sleep/standby mode while
the computer stays on. But only between set time windows (e.g. at night).
The app shows data on large format plasmas and don't need to display
information outside opening hours. But the computer does receive information
updates when the displays are in standby mode.
How do I turn off the display using VB.NET 2005/2008 Express Edition?

I dove into the exact same project a few months ago. I concluded
after a lot of searching on Google and newsgroups that the required
Windows API calls were not exposed in a managed environment such
as .NET. I gave up after that and am going to probably use a low tech
solution consisting of a programmable timer to turn the display on and
off by controlling the AC power. My displays are 17" LCDs, though,
that will probably not be damaged by having their power abrubtly
removed. I am not sure if it is okay for a Plasma to be shut off like
that. It could damage it to not go through a shutdown/cool down
procedure.
I would lovbe for someone to correct me about the .NET environment and
calling the power APIs.
