Quick question: I have an R9 290X in my main rig, and i'm trying to connect it to 3 1920x1080 monitors plus 1 2560x1440p monitor. Currently i can only get 2 of the 1920 monitors plus the 2560 monitor running. Is there a way to get all 4 monitors running? The spec sheet says it's possible. PS: it's a reference 290X.
You need at least two of those monitors connected by DisplayPort.
You could just use it in conjunction with your iGPU
