hey guys, after a bit of help here, i have 3 screens which are running 1 dvi, 1 mini display port and 1 hdmi. on the hdmi monitor the screen will not use the full screen, it has a black border all the way arround and it will not let me enlarge the sreen to full size, what am i doing wrong ??. i was thinking about just buying another mini display port adapter. my graphics card has 1 dvi, 1 hdmi and 2 mini dp, i must admit the quality of the hdmi is nothing special. any help would be greatly appreciated.
size matters

you need to make sure the mini display port adapter is active.
otherwise you cant run 3 displays

The mini display port only has to be active if the monitor hasn't got a display port input. It's for when you go from dvi to display port adapter. Like above in CCC type in scaling and it will open the picture above, with 3 there will be an option to click either screen, you do them individually, just slide the slider all the way to overscan.
