think your confusing things again or more than likely i haven't explained them clear enough, so i'll try again.
you have 2 identical monitors, each with a choice of 3 inputs you can use, vga, dvi or dp.
you have a graphics card with 3 outputs vga, dvi and hdmi.
now think of vga, dvi, hdmi and dp as different languages.
vga can only talk vga,
so your graphics card can talk to the monitor using it's vga connection only if connected to the monitors vga port.
dvi, can talk dvi and hdmi and vga (vga depends on dvi type but lets assume it's dvi-i on your graphics card)
so your graphics card can talk using it's dvi connection to the monitor only if connected to the monitors dvi or vga connections.
hdmi can talk dvi and hdmi
so your graphics using it's hdmi connection can talk to the monitor only if connected to the monitors dvi connection.
notice none of those connections on your graphics card can talk to the monitors using their dp connection.
so for your dual screen setup you are going to use the dvi output from the graphics card to the dvi connection on your 1st monitor,
for the 2nd screen you are going to use the hdmi output from the graphics card to the dvi connection on your 2nd monitor.
this will get you what you desire, and just in case your worried because both monitors are using their dvi connections then don't be because it makes no difference what connection types are used on the monitors just as long as the graphics card can talk to them through it.
those are with passive connections, which is a simple wire to wire cable connection that have the correct plugs (or adaptors) on each end to fit each connection type being used on each device.
now there is a way you can get the ports to talk to other ports that it can't normally do and this is when a decoder (think of it like a translator) or active connection type is used, but these only work 1 way usually.
so for a graphics hdmi connection to a monitor dp connection the adaptor needs to convert the hdmi signal into a dp signal, one that converts a dp signal into a hdmi signal will not work in your case, and because of the cost of such devices it really would be better to go for another connection choice or even buy a new graphics card with a dp port if your set on using the dp connections on your monitors.
i hope that explains things better so you understand what you can and can not use to get your dual screen setup working.
also it doesn't matter which monitor is connected to which graphics output because you can make either monitor the default one later in windows using amd's catalyst software.
