After realizing I have 3 monitors lying around that are nearly the same size, I attempted a triple monitor setup. To my surprise, it worked! It’s not perfect. In fact, it’s a bit jury-rigged. I’m using a DVI>Displayport adapter, one monitor with DVI only, and one with HDMI. Again, by no means a “good” setup, but it works.
As for the game itself, the only problem is that the HUD elements appear in the corners of the outermost monitors. Otherwise, it looks and plays great.
