I have a XFX Radeon HD 7850 Core Edition set up with the following displays (under Win 7):
1) A flatscreen, Acer 23,6 L GD245HQbid 3D, connected via DVI, used as a primary screen for my PC
2) A second flatscreen, LG 19 L Fla. L1972H A+D , connected via DVI, used as a secondary screen for my PC
3) A TV, LG 50PZ250, connected via HDMI, used to watch videos
I can use all three displays, but only two at a time. I would like to change that, i.e. I would like to use all three displays at the same time. How do I do that? I did a bit of googeling and I read that one has to use the Display Port for this. Is that correct and how exactly do I have to do that? It is sufficient to buy an adapter for one of the screens? (My graphics card has 2 mini display ports). Which one should I take?
