Windows 7: Third monitor not detected

Third monitor not detected

Hi all,
Until earlier I was running 2 monitors a Samsung s22b300 (connected via HDMI) and a bush TV (connected via dvi to HDMI) this worked perfectly. I then purchased another Samsung s22d300 and connected this using display port to HDMI, now this monitor and my TV shows but my original Samsung connected via HDMI does not. My graphics card is a gtx 770 which I believe supports up to 4 displays

Any ideas?

Thanks Mike

Does all displays get recognized in Screen Resolution? Can you extend to the 3rd if so?
