Max monitor selected of unity is 8 monitor?or not?I want 12 monitor selected on display resolutions Dialog. My computer have 3 Getforce GTX970 with 10 monitor.
How to show 10 monitor on display resolutions dialog???
Please help me!

Ever find this out? I am interested as well!

It’s funny that I find this thread exactly today when @mrekuc tries to relaunch it.
Anyway, I am also very interrested in it (and I swear we don’t know each other with @mrekuc)
How many monitor can we adress with Unity ?
What about performances ?
