I have a mid-2010 Mac mini that I'm attempting to connect a second monitor to with no luck. My first monitor is connected to the HDMI port with the HDMI-to-DVI adapter that came with my Mac. The new monitor is being connected via the Mini Displayport with a VGA cable that's connected to the port with a Mini Displayport-to-VGA adapter. No input or picture appears on the second monitor using this configuration. Apple says my model of Mac mini should support dual monitors just fine but I haven't had any luck. It's very frustrating that Apple has a dearth of info on this topic on their site. Any help you can offer is appreciated.
Mac mini, OS X Yosemite (10.10.5)
