I have a ATI HD5700 graphics card with HDMI (could be DisplayPort too?), DVI and VGA outputs and I want to use three monitors. Currently I have one monitor working with HDMI and other one working with DVI but if I plug the third monitor to VGA, it does not work without first disabling one of the two other monitors in the ATI Catalyst Center.
How can I get the three monitors working together?

You cannot use three monitors at the same time with that card (and every other card I know of with an HDMI port). The HDMI port uses the same circuitry as one of the DVI ports. Two monitors at once is the most you can do with that card, one DVI connection and one HDMI connection or two DVI connections.
