I think the problem is the dual link DVI-I. The card provides only 2 DVI links. The other DVI-D and the HDMI each use a single link. It should be possible to use a HDMI to DVI adapter and connect only to the single link DVI and the HDMI.
You should use a DVI to VGA adapter. It will only fit on one of the DVI ports. It is best that you connect one of the monitors to the DVI to VGA adapter and still use the HDMI for the TV as the HDMI cable can carry sound.
You should remember that two DVI or HDMI cables can't be connected to the two DVI ports.
