my hd 7950 mini display ports are not working. hdmi works fine, but when i try to use my mini display to hdmi i dont get anything for my 2nd screen. Windows 10 does not detect 2nd screen. AND YES, i have updated drivers and windows, with no luck. i had it working a few months ago, i know i didnt change my settings, but when i moved, i dont have the exact setup as before. but it should still work. i have different, cords for everything, HDMI, Displayport to HDMI female, and tried both plugs. no luck.
