VGA connection issue

VGA connection issue

Why am I unable to use a VGA cable to connect my LG IPSle23 60 HTz
monitore to my PC?
I've read that it may be a resolutions issue, I don't even like Matrix!
Seriously though, it's driving me mad, I have ALL the latest drivers,
updates and everything, and I'm trying to connect the monitor using the
motherboard connector, there is no VGA option with my graphics card it
seems, just what looks like a VGA connector but with more pins.
I can connect using the HDMI but really wanted to use VGA, I don't think
it's anything to do with the operating system either (windoze 8) as it
says it uses pretty much the same drivers etc as windoze 7.
It connects to a laptop via VGA, but my PC....no signal :(
Any offers?
