Can't extend the display to my 3rd monitor?

[jeandredalex]

Excuse my english..

My PC detect all three monitors but don't extend the display for all of them.
I can choose 2 of 3 monitors to show the extended desktop, but I can't do this for all.
All three monitors are detected and working, but I can extend only for 2.
1 and 2, 1 and 3 or 2 and 3.

My PC:
Asus Z87 Deluxe
Intel i7 4770K
3 monitors LG LED IPS 23EA53

1st connection: HDMI x HDMI
2nd connection: DisplayPort x HDMI
3rd connection: Mini DisplayPort x HDMI (With adapter Mini DP iTrend x HDMI and HDMI cable).

I have both Ubuntu and Windows.

On Ubuntu, I am using Desktop stretched on 3 dislays. No setup problem. Even gaming on 3 displays.

On Windows (like you've said above) Catalyst Control Center limits me to use only 2 displays at a time.

So Ubuntu proves me that it's not a hardware or connector problem!!! But I could not find a solution anywhere.
