DVI-A to DVI-A Result: - Analog Video Cables
This setup is not typical, however, if it is the case that your source device AND your display device both use the analog DVI-A Interface, you will need to connect these two devices with a standard DVI-A Cable.
You may also use a DVI-I Cable if both receptacles have the maximum number of DVI pin placements.
This option, however, will not result in any greater quality, as the signal will still be transferred in the analog format.
These are the cables you may need and some adapters you may find useful for your application.
