Eyefinity Setup Port/Cable Question

[camber799]

Building a new system. I have a XFX Double D HD 7770 Black Edition which has 1 each of 3 outputs:

DL-DVI-I
HDMI
Mini DisplayPort

I currently have 2 displays:
Samsung SyncMaster 2343BWX (center display, 2048 x 1152, DVI, VGA)
old Samsung SyncMaster 191T (side display, 1280 x 1024, DVI, VGA)

Question 1: Do I need to use the mini Display port for 2 display/Eyefinity configuration or can I use the DVI and HDMI ports for now?

I'm thinking that I will be adding a new display or perhaps will be replacing all of them (they're old) but my current goal is to get the new system built. When that time comes I'd rather purchase a display(s) with mini DP and HDMI support rather than purchase an expensive mini DP to DVI adapter which is about 40% of the cost of a decent display. The active HDMI to DVI adapter is relatively inexpensive (~$30).

Question 2: And, since the 2343bwx is the better and my primary display-which port should I plug that into?

Thank you for your help!

Its don't believe it is considered eyefinity unless you are using three or more monitors, you should be able just use HDMI and DVI, or all HDMI, or all DVI, or even all VGA.

I'd just use DVI for both of them.

Great news. I just found this Eyefinity FAQ page which confirms your comments: http://www.amd.com/us/products/technologies/amd-eyefinity-technology/how-to/Pages/faqs.aspx#how-many-monitors

So, since the mini DP isn't required, do I need an active adapter for the HDMI to DVI? I'm thinking not (not even sure it exists). I'm thinking that a neater solution would be to get a HDMI to DVI cable (rather than an adapter). I need a slightly longer cable anyway. Thoughts?

Many thanks for your help!

Until you get a third display you don't need to worry about display port at all.

An adapter would be cheaper (if you get it off Amazon and not somewhere like Newegg) a cable will run you more money, but it doesn't really matter.

The cables seem to be fairly inexpensive-about as much as the adapters.

Thanks again for your help.
