Hey again. I asked before why my third monitor didint work and you guys helped me out so thanks for that :) I got a new problem. I got 3 monitors now, I used to have 2, both goes with DVI connected to the graphic part of the ports behind the pc. Now, There is no third VGA nor DVI port back there, but there is a HDMI One. So I figured thats the only way. I just went and bought a HDMI cable and connected my Main monitor with it, and I want to use the other two monitors with the DVI. I try that and my third monitor remains black screen. My PC Did find my monitor, but it still remains black screen. Any ideas?

I read that I need some kind of Active Display Port, is that true? Ive seen what it looks like, and have no idea where it can fit on my monitor or pc.

Most video cards can only output two clocks. More then likely one of your ports is disabled when the other two are in use. You will need what is known as an active adapter to run a third monitor.

Please list your video card and what cables you are using.

I did list it along above. I use AMD Radeon HD 7800 Series, not really sure which one exactly. Also that product wouldnt work because Im using an HDMI Cable. Not DVI

Edit : Nvm Im an idiot. I forgot I can use one DVI cable directly, 1 HDMI cable directly, and the second DVI Cable via an adapter. Would that work?
