I'm current trying to set up another monitor on my Lenovo ideapad Z580. I've been using one with an HDMI cable with no issues and am now trying to set up a 2nd monitor with a VGA cable (because it's a little older and has no HDMI input), I keep getting an error message when I try to bring in the 3rd screen. It reads "The display settings could not be saved. Please try a different combination of display settings". Currently using terrible windows 8.1 Please help, this is really obnoxious.
