If I use the Nvidia GUI tool to enable the third monitor, it seems to work, and even changes the xorg file, but the settings don't stick and the file reverts to dual monitor on a single card.</div>

<br></div><div><br></div><div>However, the third monitor never displays anything even though it's clearly being detected. I've tried both outputs on the new card. If I exit our of the Nvidia tool, the settings are not saved and next time I open it I have to detect the monitor again. I've tried with and without xinerama.</div>
