need help adjusting the color on my monitor.  every was fine for the most part but i thought the red could be turned up a little.  and since this is my first arcade monitor, i have totally screwed all the colors.  yes i am a retard and i didnt mark the settings.   

so basically the picture is dull.  biggest problem i see is that anywhere is supposed to be red is black.  i have searched around and found a few basic guides for setting up colors but i still cant get nothing.
i am pretty sure the monitor is a Electrohome GO7.  looks similar from the monitor ID page.  Attached is a picture to make sure.  
I have two drives, red and green.  and three cutoffs, red,blue, and green obviously.
