[SOLVED] Trying to use two different GPUs simultaneously

[me.hoonigan]

I'm trying to use two different GPUs simultaneously one is a AMD HD6850 and the other is a AMD HD 8570. When I install the HD 6850 it works fine. But as soon as I install the 8570 the second monitor would be blank and no option to turn it on in settings. I doesn't show a secondary monitor. Both cards work perfectly fine. Just not together. Is there a way around this.

With all due respect, what's the point of having two GPU's that are mismatched? You could very well have all your monitors tethered to one powerful GPU, being the HD6850. If you must want to still expend resources on your idea, might want to have both GPU's populated when you try reinstalling the GPU drivers.
