2 monitors 1 tv not working

[BAaAGOAT]

Hey guys, this is my first time posting and I've read through many threads but none seem to work for me.

I am currently running:

i7 2600k Sandy Bridge 4 core processor
XFX Radeon HD 7850 Double Dispersion (2 DVI, 1 HDMI, 1 Display Port, 1 Mini Display Port)
Catalyst Control Center Version 13.4
2 HP monitors both DVI at 1920x1080
Windows 7 64-bit

Two monitors with DVI work just fine, but I run into trouble when I try adding a TV to it. I read some threads and from what I've gathered was it seems that you need at least 1 Display Port/1 Mini Display Port and 2 DVI. Since my monitors are both using the DVI, I used the Mini Display Port (to HDMI) and tried to make my TV an extended display. When I try to extend display to my TV windows says "unable to save display settings". When I open Catalyst Control Center it knows my TV is there, but it says "To extend the desktop, a desktop or display must be disabled". Does that mean I am unable to run 2 monitors and 1 TV? and if i can run 2 monitors and 1 TV, what should I do?

Yah I had the same problem, even bought a mini display to hdmi but then I found out it needed to be an active one not passive to run all 3 at once.
