You are running into:
Can I connect a DVI display?
Mac Pro supports DVI displays using Mini DisplayPort to DVI adapters. Use a single-link DVI adapter such as the Apple Mini DisplayPort to DVI adapter for DVI displays with a resolution up to 1920x1200. Use a Dual-Link DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter for resolutions up to 2560x1600.
Mac Pro supports a total of two single-link DVI displays. If you connect a third DVI display using a passive adapter or a display via HDMI, it will cause one of the three displays to become inactive.
Can I connect more than 2 DVI or HDMI displays?
Mac Pro supports a total of two DVI or HDMI displays when connected via the built-in HDMI port or using the Apple Mini DisplayPort to DVI adapter. To connect additional DVI displays, use an active DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter. You can connect up to six active adapter DVI displays. This requires a powered USB hub since Mac Pro offers four USB ports and you will need six to connect them all.

For displays less than 19201200 a simple, single link active adopter like

For greater resolutions you need a dual link adopter
My computer does not recognize a third monitor. All three monitors are connected via dvi to thunderbolt. Is there a way of connecting more than 2 monitors to the new Mac pro?
