    How are my refresh rates?

    hey guys,
    I have a question abou my refresh rate. The monitor displaus it as 59.6Hz and Windows displays it as 60Hz. Now, I have both my video card and montitor installed properly, but does this seem low??? at 70Hz the screen shakes and bounces...as well as at anything higher. My resolution is @ 1024 * 768 if that hellps.
    Thanx

    60Hz is ok, but it is better for your eyes if you have something higher than 60. 75Hz or even 80Hz is quite all right I guess. 60Hz is the default, which means in every resolution supported by both monitor & VGA card in 60Hz everything should run smoothly. When you go to higher values depending on your VGA & monitor, things could get rough. Some VGA + Monitors cant work together to produce a good output at some higher resolutions. If you can’t get a clear output at 70Hz then try some other refresh rate like 75,80.

    Not very refreshing! Something is very wrong. 60 Hz will make you go blind in no time. The typical refresh rate at 1024x768 is 85 Hz. Anything over 75 Hz non-interlaced is OK for your eyes.

    Well guys,
    why would my monitor do this then? at 60Hz its okay. at 800*600 with the refresh at 75Hz its okay! but at 1024*768 it starts to bounce and jump and shake alot and very VERY hard on your eyes. So why would it do this???? Its not the monitor...I just bought it...what else?!
    thanx

    Intel_Dude, you're not the only person with this problem.

    Monitors I have used will have a jittery picture over a range of refresh rates. There is usually zero jitter at 60Hz, but in the 70-75Hz range the jitter effect is terrible. The effect goes away at 80-90Hz, depending on the weather.

    No, I am not crazy, its just EMI. I've observed this effect in multiple monitors, in different rooms. I have also noticed that, like low refresh rates, some people notice while others don't. Its a VERY SUBTLE jitter, but thats what makes it so annoying.

    Now, the important part: what to do? You'll can boost your refresh rate to 80Hz or more to remove the jitter. You can also try moving the monitor to another place in the room (away from the source of the EMI), I've found this can help too.
