I just placed an order for a Dell XPS 8700 PC with a GeForce GTX645 video card. I'm trying to figure out how I'll be able to connect my two Dell monitors to the video card. My monitors are a Dell 2407WFP-HC 24" and a Dell IN2020M 20". I'm fairly certain the 24" monitor has a DVI-D connector, and I think (but I'm not sure) the 20" monitor also has DVI-D.
It appears from looking at the specs for the GeForce GTX645 that it has one DVI-D port and one DVI-I port. If that's the case, how do I connect two monitors that use DVI-D to the video card?
Solved! Go to Solution.
DVI-I=DVI-D + D-SUB (VGA). This port supports the two connections (analog one with a DVI->VGA adapter). There was an old one, "DVI-A", that was analog only but I've not seen this port in any card.
On my current PC (the one the new PC will replace), the video card has two DVI-D ports which I use for the two monitors. No adapters are required for this setup. What adapters, if any, will I need to connect the same two monitors to the new video card (the GeForce GTX645), since it appears that the new video card won't have two DVI-D ports? Or am I misreading the specs for the GTX645?
As you can probably see, I don't have a great understanding of DVI-D vs. DVI-I vs. just plain DVI (which I've seen references to, and which confuses me to no end). Any help would be most appreciated.
Yo do not need any adapter to plug 2 DVI-D monitor to a DVI-I + DVI-D + HDMI + [...] video card.
DVI-I means that it is a DVI-D compliant port AND that you could plug a DVI-to-VGA adapter to use an old monitor (VGA dsub 15 pin)
DVI-I just means that DVI connector has some extra pins (right, edited, my mistake) with analog data (if needed)
NOW I understand, thank you for the clear explanation. It looks as if I'll be able to simply plug my two monitors into the video card and I'll be up and running.
Thanks again for clearing things up; now to visit that Wikipedia article for a more in-depth understanding.
