I have a AMD radeon hd 6670, you can look up the specs yourself. LG M2255 that I use as my monitor. That's connected via the vga port as a while back I had problems with its hdmi and was forced to plug that in. I have a acer v203h from my older pc. Basically can I/what would I need to do to do dual monitor with the older monitor? I did do it with my old pc with the older monitor but never really had a need for it so didn't use the dual monitors for that long, but I could use it now on my current.
