DVI There are three variants of the DVI connector: DVI-A, DVI-D, and DVI-I. DVI-A is an analog-only connection VGA HDMI Because HDMI and DVI are similar, you can convert from HDMI to DVI by adding the appropriate adapter Display. Port The signal that originates from a Display. Port can be easily converted to DVI by using a Display. Port to DVI adapter. However, the inverse is not true. When you have to convert a DVI signal to Display. Port, you must use a Dual-Link DVI to Display. Port converter. You can also use a mini. Display. Port to Display. Port adapter. TIP: Use an active adapter rather than a passive adapter to avoid common video problems
