Most Stone PCs come equiped with a range of output ports, depending on model.
The 15-pin VGA port is slowly being replaced in favour of more modern alternatives, such as DVI, Display Port, and HDMI. If your Stone system includesa Blue DVI port (DVI-I), then this can be adapted to provide an 15-pin VGA port using the DVI to VGA adapter included in your manual pack.
Systems that include a white DVI port only (DVI-D) usually cannot be adapted to provide a 15-pin VGA output.
Note: The Intel DQ67SW and DQ77MK are example motherboards that do not include the 15-pin VGA port but do however include the Blue DVI port which can have the adapter fitted.
