More precisely Acer Aspire 3630.
There is the eManager->ePresentation utility, which normaly takes care of setting video signal.
It can be set to LCD only, External, Both.
It used to work nice, but suddenly it is not possible to switch the radiobutton into the position External or Both, which results in the fact that there is no video signal comming into projector.
Btw, there is also similar setting for boot-time period (don't understand why). Here I can switch it into Both, which results in the appearance of the video during the short time of laptop booting.
I don't understand why this option, but at least it tells me HW is okay and it must be some SW problem.
Anybody has a hint what could be wrong ? I even reinstalled the VGA and eManager drivers - but no help.
Couldn't be something in windows registry or some other persistent setting ?
I'm running quite desparate as I cannot use data projector with PC.
