Multi GPU?

[Patrickb]

Ok so I recently got Vjing assigned to me at a decently sized club (980 people) We are running 3 projectors and a control screen. Every projector is mapped to fit the screens perfectly so I need seperate outputs. I can get two running seperate outputs but the last plug (display port) doesnt give a signal. I've never ran more then 3 screens so I'm assuming its gpu limitations. Could I run a second card without crossfire to run more screens? I run my onboard and gpu at the same time sometimes but is it possible to run a second gpu side by side? I dont need it for gaming just multiple outputs.

Processor:
Intel i5-3570K LGA1155 4 Cores @ 3.4 GHz

Motherboard:
Asus P8Z77-V

Graphics card:
Radeon DirectCUII HD7870 2GB
2 DVi, 1 hdmi, 1 display port

Ram:
G.Skill Ripjaws X series 16GB (2X8GB)

Power supply:
Already upgraded to 1000W

Thanks!

Edit: Projectors run on 640X480 resolution and looks great.

7870 can work with the last displayport, you just need an active display dongle, not a regular one.

This has nothing to do with Resolume. If the displays aren't working in windows then they won't work in Resolume.
