Hi, im currently using a Radeon r9 270x for my graphics card, and im trying to connect 3 monitors on to it. I can use 2 of the monitors but when I try to make the 3rd one a extend display from my desktop it gives me a error message saying that i need to change my display setting. My main monitor is connected to HDMI port and both of my other monitors are connected to a DVI slot, one of them using a VGA to DVI adapter since there is no VGA on the graphics card. IF anybody could help in making my 3rd monitor possible it would greatly appreciated.
