    well tjhe higher the refresh rate (hz)
    the better
    as the screen will refresh the immage 120 times a second? at 120hz
    and only 100times a second at 100

    really anything over 80hz wont hurt your eyes really

    but why not try upping the resolution?

    Do not exceed the specifications of the monitor and/or the video card/chip.

    IMO, 75Hz and above is good. I have my monitor set to 1600X1200@85Hz.

    if you can't find out the specs on the web, go here:

    download ddctest, if your monitor is plug-and-play, this program will display what resolutions & frequencies it supports.

    anything over 75Hz is sufficent, i usually go for 85.

    By the way, what does BTW stand for?

    It is better to be tried by 12, than carried by 6.

    Or you can just look on the back of the monitor and see what its max horizontal scan frequency is and compare that to similar products, or do a bit of maths. As a guide, you divide the horizontal refresh rate by the number of vertical pixels you wish to display and that should give you a pretty good estimate of how high a refresh rate it can do, e.g.

    It says 75kHz on the back of your monitor, you want to know what refresh rate you can use at 1024x768.

    75,000/768 = 97.7Hz vertical refresh

    So that monitor would comfortably do 85Hz refresh rate. Continuing the example for higher resolutions gives these results:

    1152x864=86.8Hz
    1280x960=78.1Hz
    1280x1024=73.2Hz
    (1600x1200=62.5Hz)

    Seeing as Windows won't let you run at odd numbered settings these will equate to 85, 75, 70 and 60Hz for the above resolutions.

    However in order to get Windows to display anything exactly what your monitor can do it needs to have a driver for it, then it should automatically allow the highest frequencies available. If you can't get hold of it then you can download a utility called Powerstrip that will let you manually setup a custom monitor driver with only basic information from the back of your monitor and its maximum resolution (which is still an unkwown). I would play safe at 1280x1024 as a maximum, even old 15"ers can do that, yet still even a lot of cheaper 19" monitors can't do any more. Hope some of this helps.

    i think i get it but...

    so powerstrip is a custom driver for the monitor?
    I'm asking cuz i have a sun monitor, and a windows machine. I got a spark to VGA adapter, but there's no display.

    Someone told me to try it at 60 or 63 hz, is that just a setting somewhere?
    I'd try powerstip but i have no moneys...*sigh*

    /edit/ i just looked on the back of the monitor and it says 50/60 hz

    thats electricity not refresh

    look for data in kHz (probably on the net) and then use formula Bennyboy posted

    Unhappy

    // babbling removed //

    disregard the above, I checked online and the monitors i have are specifically NOT pc compatible. I guess the adapter i have is for some other spark monitor to VGA
    thx anywayz guys!
