I`m having a LG flatron monitor adjusted on 1024x768@85Hz, the question is the more refresh rate the better view, or it has something else related to? and does anybody know about the Moire option ?
thanks in advance :)

Images flash before your eyes. The slower they flash, the more likely they are to cause headaches. In motion pictures, old movies flashed at a slower rate, hence the choppy movements.

A more serious problem is using a monitor in a room with flourecent lights. These flash at 60Hz in North America 50Hz in most other countries. If your monitor is flashing at 60Hz, it can cause the image to look choppy. If it fluctuates just slightly from the lights, it can make scrolling bars appear. Not a good choice.

Now, problems could occur at even multiples of 60Hz, such as 120Hz. Or even at close fractional multiples, such as 90Hz.

It's my opinion the smoothest (least flashy) image comes in frequencies between 70 and 85Hz, or 100-110Hz (at least on the North American power standard). Since most monitors can do 70-85Hz, they're good choices.

Moire affects the shape of the picture at the sides, use it to adjust your monitor so the image fits squarely on the screen.

In the monitors manual it was mentioned that the best adjustment for the moire is H:0/V:0, but I found out the edges dont go smooth this way, the best way was H:0/V:99 !!! or was i wrong !
and as for the refresh rate i've got my monitor on 85Hz but i dont know i just feel something's wrong, or may be cause i'm not used to it

You adjust it so it looks best.

I don't seem to notice a difference, but does an increase in refresh rate lower the performance? e.g. a game at 60Hz will have higher fps than a game at 85Hz?

no refresh rate has everything to do with the monitor not the VGA itself

No a higher refresh rate is not likely to decrease your frame rate.

Many people who use monitors for longer periods of time complain of headaches or eyestrain when their monitor is set at 60Hz. Having it set higher will lessen the impact on your eyes.
