I'm trying to add a VGA monitor to my PC so I can have 2 monitors. I am running Windows 7 and have an AMD Radeon HD 6670 graphics card. It has a DVI slot I'm not using and an HDMI slot I am using. I plugged the monitor into the onboard VGA connector and it is not getting a signal. I went into the BIOS and changed the standard video input to be the onboad one and then the VGA monitor worked, but my main one did not. I then switched it back so i can at least use what I'm used to. I have also tried using a DVI to VGA adapter in the DVI slot but apparently that doesn't work because it doesn't change the signal to VGA.
Is there any way that I will be able to use both monitors at the same time?
