I have an ATI Radeon 4870HD graphics card which has a Mini Displayport and a Dual-Link DVI port. I'm connecting this to two Dell U2410 which each have a Displayport, HDMI ,DVI and VGA ports. I can connect one of the monitors straight to the DVI port, but what should I do with the other? I can't find a Mini Displayport to Displayport adapter for sale in the UK. But there are Mini Displayport to HDMI adapters and Mini Displayport to DVI adapters available. Also, would it be best to have both monitors on the same connection? If i go the HDMI route should I buy a DVI to HDMI adapter for the other port? Or have both on DVI? Will there be a visible difference between the monitors if they're not on the same type of connection? Which would be best for graphics, 3D production rather than HDTV movie watching? Do these questions makes any sense? Hope so. Thanks.
