Trying to run a 3rd Monitor, any hardware sugguestions?

[theshaner]

My current setup:
NVIDIA GeForce GTX570 w/ 2 Acer Monitors Attached via Digital Ports
Gigabyte Z78-UH5D
Intel i7
16GB RAM

OSX 10.10.5

I have a 3rd Acer that I would like to hook up and am having no luck. I have tried the digital port on the motherboard as well as the HDMI port on both the video card as well as the motherboard. Sometimes it will almost work, but it ends up scrambling the screen and locking up the system. Is there a good way to do this? Different drivers, different card, etc?

Thanks!

The GTX 570 is a dual head card, so it can't drive more than 2 displays at a time. Only Nvidia GTX 600+ or AMD HD 5000+ generation cards can do this.

You should be able to use your iGPU and dGPU at the same time. There are various threads on this topic.
