What is the difference between DVI-I, DVI-D, and DVI-A?
DVI-I
I is for integrated. It can handle both digital and analog signals.
DVI-D
D is for digital. It can only handle digital signals.
DVI-A
A is for analog. It can only handle analog signals.
Looking at this I realized that some might have problems identifying which connector is which. I provided the information below to expound on the explanation.
For the first two variations above their are actually two more variations as there is a single link and a dual link version.
As one might expect, single-link DVI is the slower, less capable version as it only supports up to a 60 Hz refresh rate with 1920 x 1200 resolution while dual-link DVI supports up to 2560 x 1600 at 60 Hz resolution.
You can identify the connector you need by matching the pins below.
