For the past 4 years, I haven't had a problem with the graphics card supporting dual monitors and then suddenly it stopped showing both monitors. I have a DVI cord from my older monitor and a HDMI cord for my newer monitor. When both are plugged in, the DVI connection doesn't work. If I unplug the HDMI cord, the DVI connection suddenly works. I have the latest drivers. What could be the problem or what other information do you need?
