Titan GTX SLI mode with Multiple monitors

Hi everyone,

I am looking to use two Titan GTX GPUs for scientific computing, mostly will be using the GPU compute in OpenGL or OpenCL  (pref. the latter).

I want to use SLI to bridge them together, but I would like to use more displays than the number of ports available on a single card.  Each card has 3 outputs, but I would like to use 4 displays.

I was told that when you SLI two video cards or more, you can only use the outputs of one card.

Is there a way I can use 4 outputs, perhaps 2 on each, and still have it working with SLI?

You're correct - if you SLI the cards you get to only use the outputs from the first - but a single Titan card is capable of four independent outputs:

Dual Link DVI-I
Dual Link DVI-D
HDMI
DisplayPort (with DVI Dual link adapter)

And using nVidia Surround 2D to drive all four outputs.

Ok, just double checked the outputs, you're right.  Thank you.
