I have a work computer (HP Pavilion s51114 slimline) which is only a year old. It has the Intel HD family graphics card. It already has the one monitor hooked up to the DVI connection on the tower, and the only free connection is the VGA port. I was wondering if it is possible to buy a VGA cable or a converter from VGA to DVI, and get a second monitor to use for an extended desktop (not a mirrored)?
