Is anyone able to enjoy 0 brightness setting and 75-76hz refresh without having the monitor make any noise?
Yep. Between 0 and 10 is what I generally run it at, and no noise at 75hz that I can hear, and my computer is quite silent.
Managed to get my 2209WA at 75Hz. Anyone have good ideas how to test this silky-smooth refresh rate?
If the monitor says 1680x1050@75hz when you hit the menu button, you are in good shape. If you move the mouse smoothly and you don't see a rhythmic pause in the motion, then it is working.
