It is possible to measure color signal voltage level to detect connected monitor or graphics card. Most monitors measure GREEN signal.
Above is what I found on a website.
And there's a 'port characteristic' discrepted as 'monitor sense' in some document from Intel about Calpella Platform that I have. I checked Montevina&Napa, same discreption.
Those are the only information I found so far about the topic. Obviously not detail enough.
Anybody could help?
Lots of thanks.
I'm interested in this as well. If someone could provide some more details about the monitor detection mechanism implied by "monitor sense", it would be greatly appreciated.
