    Firstly, I know the refresh rate doesn't matter for LCDs, its the response times.

    However, I have the otpion for my LCD to have it at 60Hz or 75Hz. Even if this has no effect on blurring etc, which one is best?

    I am assuming 75hz? Is this correct?

    It won't shorten the life of my LCD will it? (i'm thinking along the lines of OCing shortening CPU life etc...laugh at me if you must)

    yo grudger. set it at 60hz . 60hz is the switching rate of alternating current here in the u.s. some other countries may use the 75hz speed.

    My Princeton Graphics 19" LCD specifies 1280x1024 at 60hz for the best results. I suspect if you read your skimpy manual, they may make a similar recommendation. :)

    actually its 70Hz, not 75Hz, if that makes a difference.

    Generally, it's best to set the refresh rate to something other than the frequency of the local power supply. Seeting it the same can result in unusual strobing effects between the screen and any non-incandescent light sources and result in eye strain or headaches. Setting it to 70 won't reduce the life of the screen and will insure that it is different from surrounding lights.

    Your going to want to set it higher than the Hz of the AC in your country unless you enjoy flicker. I know this to be true for CRT. I won't stake my name on LCD settings.

    I thought the 60-75 hz was the refreh rate. that is how many times a second the monitor puts a new picture on the screen. For a comparison, a non-interlaced (progressive) TV will run at 60hz. Old interlaced TV 30. If the frequency is to low, you will see flicker in the image. you should set it at the lowest frequency that produces the best image. I have my LCD at 60hz. 75 or higher made no difference. The higher the frequeny the more you computer and/or video card must work to produce the image.
