You may have already met the Female-to-Male version of this DVI-A Male to VGA Female Adaptor, and its twin is just as clever!
This adapter works together with analog-ready DVI-I sockets and adapts them to work with VGA devices; perfect for getting mismatched inputs/outputs to work together. Be warned; not all source DVI-I sockets are created equal, so always check your user guide for confirmation of VGA compatibility via the DVI connection when working with outputs (like from the back of a computer).
*Adapting DVI source to VGA screen: Check your hardware manual first to ensure that your DVI device can work with VGA signals. This adapter is not a video converter and can't work with digital-only DVI Sockets, even if they have the correct pin holes. Some manufacturers use DVI-I sockets even when they don't carry VGA!
*Adapting VGA source to DVI screen: Most DVI screens take care to use the correct socket to avoid incoming VGA signals, such as the DVI-D socket above. If your display features a DVI-I socket, it is usually VGA compatible.
