One display port and two from the DVI-I dual connector.
Any combination of connectors work as long as the third connector is displayport.However,make sure that the dvi port can push the resolutions you require (i understand you want to split the connector for two monitors).However,I would suggest using the d-sub/HDMI port too if you have one since multimonitor on a single dvi port can be sketchy.
No, I don't also have an HDMI port ... that would make it easy. Only displayport and DVI-I. My question derives from looking for splitters for the DVI-I and many of them specifically state that they are for displaying the same content on both monitors. That is *not* what I want to do. So, I am looking for assurance that *somewhere* there is a DVI-I splitter to *something* which will give me two separate displays (although I would like all three to be treated as part of one screen logically).
Is it an Oem part?If so,your connectivity might be reduced and the other route might be "splitting" the displayport,since dp nativelly suports this.

It is just a card in a Dell box. I.e., it was sold as an AMD Radeon HD 6450 from a list of options.
I found this page http://support.amd.com/en-us/search/faq/7 which suggest that the 6400 series can support "up to 3" monitors, but there is nothing there which makes it clear *how* one does that given that the board I have has DP and DVI-I outputs.
That is for standard gpus sold through
the retail market.Oem units such as yours might feature added or missing features,in your case a dsub (vga) port.Ask dell and see what they say about it.Either way in order for a multimonitor setup to work,regardless of gpu version the third display and those who succed it must be powered by the displayport port.
So, even though the DVI-I plug is dual, I can't use that for two independent displays?
Asking Dell about anything seems difficult these days. The box in question is out of warranty, thereby blocking access to tech support.
I might be wrong here,but those radeons are generally low profile cards,meaning the D-sub port might be attachable.Open the system and see wether you have a gpu like the one attached.If it has the VGA internal connector you can get away cheaper.
