Weird video card problem?

I honestly don't know what going on, but about 5 hours ago till now I cant seem to get my video card to connect to my extended monitors (2 of them) right now only my main monitor seem to be functional... this never happen before just only till recently.


What I have tried is...
restarting com.
cleaning (use some compress air on the jack and the graphic card itself)
google

all my monitors are different sizes and my graphic card is a XFX Double D Radeon HD 7850

Have you first made sure one of your monitors didn't just bug out? Try each one alone in both ports of your gpu?

Have you tried reinstalling the latest video drivers?

yeah, i think figure out the problem... one of my monitor is kinda dead plus it keep tone down into yellow and back to normal. x.x
