oliiimac Posted May 9, 2011 Share Posted May 9, 2011 Hi there, I own a hackintosh currently with a GeForce GT240 in it with 2 monitors running in extended mode. What I would like to do is add another cheap card (eg. GT210) into it and have a triple monitor set up. However, because my third monitor will be a 40" TV I was wondering if it is possible to have my primary monitor mirrored to the TV using 1 card and then have my other monitor in extended mode using the other card. That way I can continue using my computer with dual monitors as I do now but then also be able to sit infront of the TV and use it there. Note: I do not want to use a hdmi splitter unless this set up is not possible. Thanks in advance.

Gringo Vermelho Posted May 9, 2011 Share Posted May 9, 2011 You cannot use more than two displays on a single nvidia card in OS X. This is true on real Macs as well. I heard that this is actually a hardware limitation and on Windows this is done with some kind of software trick in the drivers. I guess you could connect a 3rd, cloned display via an external splitter thingy but I don't know how you would deal with the difference in resolution on the two displays. For sure everything would look like {censored} on the display that is not running in native resolution.

oliiimac Posted May 10, 2011 Author Share Posted May 10, 2011 I understand that you cannot run more than 2 monitors off a single card which is why I would have two (GT240 + GT210). Also all the monitors will be running at 1920x1080 so there would be no resolution problems. Does anybody have a multi-monitor set up with 3+ monitors that could quickly test this theory for me?

oliiimac Posted May 11, 2011 Author Share Posted May 11, 2011 I bought and put in the GT210 and have all 3 monitors working now as extended desktop However, I cant make my primary display mirror to the TV. Alwell looks like ill just be changing my TV to be the primary monitor when I want to use it.
