So I had been running dual monitors, but when I tried to update my drivers (Radeon HD 6700 series) my second monitor stopped working and now it's not being detected. I've tried the classic unplug/replug but I'm not having any luck. The driver update messed my computer update to the point that I had to do a system recovery.
Additional info may help 'cause I'm still having trouble.
The monitor works when it's plugged directly into the Video card monitor slot, and the second monitor was plugged into the monitor port in the blue area above.
That's why, with a graphics card they usually disable the onboard video. You can get a VGA-DVI adapter and use both the VGA and the DVI ports on your graphics card.
I have to do VGA - DVI - HDMI. I think I have a spare VGA - DVI somewhere around here.
that wont work:
hdmi is a digital only connector, dvi-i is digital+analog and vga is analog only.
hdmi <-> dvi works because it just changes the pinout for the digital signal to the other plug type.
and dvi-i <-> vga does the same, the little plus with 4 pins on a div connector is a separate analog signal.
the problem in that trying to go hdmi -> dvi -> vga you won't be getting any analog video signal.
and trying to get 2 different video cards(onboard+discreet) working at the same time is bloody hard, it's why you should disable the onboard video when you install a discreet card.
