DVI Types

[crazysteve240]

I have two old VGA monitors and I want to put them to use, but my graphics card only supports DVI, HDMI, and Display Port. Does DVI type matter when converting the signal to analog VGA? (i.e., DVI-D, DVI-A) 

 

According to Wikipedia, DVI-D is digital-only and DVI-A is analog-only. But, I am not sure.

DVI-D can be connected to other DVI ports

DVI-I can be connected to other DVI ports and VGA ports

 

You don't need to know anything else, DVI-A doesn't really exist outside of google search diagrams and wikipedia, I honestly don't know why people mention it so often in forums. You can find it sometimes as a connector on DVI to VGA adapters since only the analog portion is needed, but the compatibility is no different than an adapter with a DVI-I connector, so you can just ignore the distinction. If you have a DVI-I port, you can use a DVI to VGA adapter. If you only have DVI-D, then you can't.

what gpu?

 

you need dvi-i to us a vga display, most new gpus have dvi-d only and you need a active display port to vga adapter to use it as it has no analogue output on the card.

It matters. DVI-D is digital only, DVI-A is analogue only and DVI-I is both. VGA is an analogue signal, so if you have DVI-I or DVI-A, use it as it just needs a passive adaptor. For DVI-D, you will need an active converter.
