rowdyiqballs :
its a xfx radeon hd 6870. thx for the reply!
Okay, it is quite standard connectivity: 1xDVI + 1xDVI-S, 1xHDMI (but you can use either the DVI-S or this) & 2 x miniDP.
If you haven't bought any adaptor yet, just use the following connection:
-----------------------Graphics Card Port
Monitor 1 <---------> DVI (via direct DVI cable)
Monitor 2 <---------> DVI-S (via direct DVI cable)
Monitor 3 <--------->miniDP (via miniDP to DVI active adaptor + DVI to DVI cable)
If you have already bought the HDMI to DVI cable ( too bad because you don't really need it ), then you can use the following configuration:
-----------------------Graphics Card Port
Monitor 1 <---------> DVI (via direct DVI cable)
Monitor 2 <--------->HDMI (via HDMI to DVI cable )
Monitor 3 <--------->miniDP (via miniDP to DVI active adaptor + DVI to DVI cable)
Here is the sample miniDP to DVI adaptor. You can choose other brands that fits your budget. Some are as low as $10.
