So basically it goes like this, my graphics card broke, they fixed it for me, now when i plug in my two monitors 1 of them doesnt work, it get recognised by windows in the resolution section, but the monitor doesnt display any image, the monitor works fine has power and say ssomething along the lines of turning off for power saving or something, well now, i believe it is in the bios setting i need to reenable it coz i was playing around there when my graphics card broke down coz i was trying to fix it :C. i got a asus z87-C motherboard and a gtx 760 gygabite gpu.
