when i hook up my monitor up for dual display, it has the option of 60 or 75 hz. Which should i use? They both look the same, just not quite sure of what the different settings do.

Is it a CRT or LCD - if you have a CRT at 60 and have the lights on in the room, you'll notice flickering - since the screen refresh rate is the same as the frequency of the AC power in the bulbs. Use 75 in that case.

Does't matter then, they don't refresh. You should try hooking it up digitally. Set it to 75 anyways, the higher the better.
