My extra monitor on my laptop (win7) is black, have been working for months and now its suddenly black? Ive tried with another monitor, same issue..?

usually laptops have shortcut buttons for choosing between display modes (laptop only, dublicate - extended desktop.. etc) are you sure the correct mode is selected!? you can also configure through gpu or igp control panel!
