How to configure two VGA ports on a PC?
Posted on 2014-09-20
The customer has a Win7 Pro PC with a VGA and a DisplayPort connection. We need a second VGA connection, with plans to run two monitors where they are a mirror image of each other, i.e. both showing the desktop. For this application, I cannot use anything but VGA, because we are using video extenders that only support VGA.
I bought them a video card that supports VGA, DVI, and DisplayPort. The problem is that when I install it, it seems to completely ignore the VGA output on the mainboard. And, after looking at the brief documentation, I guess maybe that is the way they intended, because they talk about disabling any existing video connections. I tried everything I could find to show the 'detect' and 'identify' video outputs, but all it would ever show is the one VGA monitor connected to the VGA port on the card I installed.
How can I get two VGA outputs? Do I need to buy a second video card? Do I need to buy a certain make and model that allows this? If so, note that this is a small, low-profile cabinet, and all I need is basic VGA output, i.e. no need (and no room) for large-profile cards with high-tech gaming capabilities. TIA
