Hey community, this is my first post-- so please be gentle!! 
I'm trying to connect an older "Optiquest Q7b" monitor up to my Macbook Pro (Mid-2010 model). I went to my local Best Buy and purchased a Mini Display Port to VGA adapter, and I know for a fact the monitor still works (I just tested it on my parents old Windows XP).
I connected it together, and though my macbook does "detect" the monitor, there's currently no Input signal on my second monitor. I tried changing the resolutions and refresh rates around to see if it makes a difference-- but nothing. My mouse will even disappear off the desktop if I move it over to the other monitor, but still-- no picture.
Any suggestions?
