    Monitor Refresh Rate

    While reading another post, something popped into my mind here that I had been working on, and then got away from. I have a computer running Windows ME that sometimes seems like the monitor is flickering on the parts of the screen where your eyes are not directly focused. It seems like you'll usually see it out of the corner or side of your eyes, but won't notice the flickering directly where you're looking. The refresh rate settings in the display properties has only 'Adapter Default' and 'Optimal' as the only two settings. Is there something screwy with the adapter driver or maybe the monitor driver files that are allowing only those two choices? I sweated over it for a little bit, than it's kind of slipped my mind for a while, but now a user experiencing the problem is bugging me about it again. The computer is an IBM Netvista and I've downloaded the adapter drivers they have out on their website and reinstalled those, and downloaded drivers for the monitor and installed those. I still would only get the two options for the refresh rate however. Any thoughts?

    Re: Monitor Refresh Rate

    I don't recall if I noted this before, but at home I run my desktop monitor at 60Hz in a very high resolution with no eyestrain. Ambient lighting is more important to eye health, and I would never sit in a room with no lights and let my eyes bug out on the monitor. <img src=/S/innocent.gif border=0 alt=innocent width=20 height=20> In all seriousness, I don't have a problem with this situation and I wear corrective lenses. At the office I've settled on 75Hz because of the fluorescent lights, which cycle at....you guessed it....60Hz.

    PowerStrip's site appears to be down. I got a 403 - Too Many Users (just goes to prove that some error messages are worthwhile <img src=/S/sarcasm.gif border=0 alt=sarcasm width=15 height=15>). I did manage to find a few alternate download sites by Googling along:

    <UL><LI>ZDNet has a nice little <A target="_blank" HREF=http://www.zdnet.com/downloads/stories/info/0,10615,42254,.html>write up and a download link</A>. I specifically mention them because the site should be reliable.
    <LI>If that doesn't work either, <A target="_blank" HREF=http://www.google.com/search?num=50&hl=en&newwindow=1&as_qdr=all&q="Powe rStrip"+site:zdnet.com>here's a Google search link</A> to find some download sites quickly.[/list]

    Re: Monitor Refresh Rate

    I've always been intrigued with the fact that round objects like eye-balls have corners, but anyway....

    From the deep recesses of my memory, I recall learning in biology lessons a couple of things:
    1] Your brain doesn't see a continually updating image from your eyes. The refresh rate is something a little under 50Hz (it may be nearer 30Hz) so anything updating faster than that appears 'seamless'. However, the optimum settings for monitors appears to be around 85Hz.
    2] The light receptors in the back of your eyes - I think they are called cones? - are different on the edges than in the main central part. Basically, at the edge they see in monochrome and I think refresh at a slower rate. (This is why you tend to detect movement out of the 'corner of your eyes' more readily than if you are looking directly at something.)

    But that doesn't really help - although it may help you understand why you tend to see the flickering you do.
    You could try the download for Powerstrip referred to in <A target="_blank" HREF=http://www.wopr.com/cgi-bin/w3t/showflat.pl?Cat=&Board=98&Number=111947&page=&view =&sb=&o=&vc=1>this post</A> - it may add some functionality and let you set a higher refresh rate.

    Edited to say: - see new links referred to below.....
