My school's computer admin a while ago tried hard to get the entire school to convert to Windows 98 Plus!(plus nothing), and the only reason he has a job is because the school is running Windows.
AND THE SERVER IS RUNNING WINXP Pro. HOW HOMMO!!!!

so he's keeping his job at other people's expense, that's how the world is...

Hmmmm my school's admin might be incompetent to.
She said I shoulden't set the school computers to 85hz refresh rate because raising the refresh rate can cause damage to the monitor. Incompetent?

Warning: Setting the refresh rate too high for the monitor can in theory damage it. In practice, this does not usually happen; if you set the refresh too high the monitor appears to go "haywire" but returns to normal when the refresh rate is dropped. Still, better safe than sorry.

No, not necessarily.
Older monitors could be blown easily if you put a refresh rate on them that they were not designed to handle. Newer ones usually have safety circuitry which prevents them from being overdriven.
However, running at very high refresh rates _does_ shorten the lifespan of a CRT-type monitor. Whether 85 hz is a very high refresh rate for the monitor(s) in question, I cannot say.

Well she could be right if you're using some kind of old monitors. Newer ones will override settings that could damage them and just switch off by themselves. Anyway, 85 Hz is too much for any monitor and could seriously reduce its life span.

So, how does one change the refresh rate? My Gateway monitor has quite a number of adjustments but none of them are so labeled.
-
changing the refresh rate is done in your operating system, not using the onboard controls on your monitor.
my school's system admin is incompetent too. i find this method of hacking very easy - walking into the admin's office and using the machine there... :/

Hmmm very interesting. Well, 60hz is hard on the eyes. Im spoiled on 100hz! Surely my monitor will last for many years though, it is 2 years old I think. Is it true that higher refresh rates slow down the video card, causing worse performance?
Chances are most students at the school do not know how to modify refresh rates(or know what they are), so my insignificant time spent with 85hz makes no difference.

Well it's actually the video card that determines the refresh rate. Video cards have a certain number of "clock rates" built in to them. You select the clock rate in the operating system driver which tells the video card which clock rate to drive the monitor at. Your monitor is just along for the ride so if you select a clock rate that your monitor is not capable of, you just may get a poof of smoke.
Most video cards and monitors today are smart though and the driver will check the maximum limits of the monitor and not let the video card go to a higher clock rate than the monitor is capable of. I'm not sure if the clock rate that the video card is running effects the performance of it. I don't believe it does because I think a separate chip (probably the DAC) is responsible for the clock rate (refresh rate).

Altering the refresh rate can destroy a monitor easily. It will not necessarily go haywire if you raise it too high. The monitor can keep on working as if normal (particularly on the better quality monitors).
If you raise the refresh rate listen very carefully at the top vent. A high pitch buzz may be heard. If this happens your systems refresh rate is too high for the monitor. It may switch on after a few days, or it may start straight away. Lower your rate to a default level instantly. It will almost certainly occur before the monitor fails, but it may not give you enough warning to prevent damage (months or only seconds).

Monitors are still tempermental to those things..
however... we have an admin who as far as anyone knows, only has a MCSE and dropped out of TAFE.
other than that..
He spends most of his time downloading pr0n, and on the fone to tech support, to make all the things he doesnt know work again.
We, the competant users, are at this time breaking everything in sight and offering him security manuals to fix them.
We are so nice ...

The funny thing is, this article says that few people notice flicker at or above 72hz. Unless there is a difference between "flicker" and "ease of viewing", I must be very gifted. I swear 72hz is not enough for me! 85 does pretty good, but I feel that 100 is even better. Maybe I'll have to see if I can see any difference between 100 and 120.
