I have an AMD R9 200 Series graphic cards which has 2 DVI, 1 HDMI, and 1 DisplayPort ports available. I've connected two monitors which DVI and the other with HDMI but only 2 work. I've read from this post which is almost a duplicate but my take on the answer is that the OP of that question's card doesn't not have 3 monitor capability at all. Whereas with my card, it should since it has a DisplayPort option. Now do I have to buy a DVI to Displayport adapter or is there a way to "tweak" to make it work as is?
