So on my card I have one DVI-D, one DVI-I, one HDMI, and one DP port.

I plugged a DP-DVI-I adapter into the DP port, monitor 1 works.

I plugged a DVI-I-VGA adapter into the DVI-I port, monitor 2 works.

I plugged an HDMI into the HDMI port. Monitor 3 will not appear.

Opening catalyst, in the arrange desktop area, it is detecting three monitors. When trying to extend display to the third (HDMI) monitor, it says "a display must be disabled" so basically I'm only being allow 2 monitors of three. The combination doesn't matter, I just can't have three.

What gives?
