refresh rates

I have a Sony GDM 20se monitor. Should I use the maximum refresh rate offered(120), or for the sake of monitor life-span, should I go with something like 85? Do I get a noticable difference in quality above 85 (I think so) or is it my imagination?

I'd say that your monitor is going to outlast the useful life of your computer regardless, so if you can see a difference, go with 120.

the monitor will probably use slight more power at 120... noticable maybe over 3 years.. :)

your eyes shouldn't be able to detect visible differences after about 80Hz, but your eyes get tired faster at a lower refresh rate. Therefore i recommend running the monitor at 100Hz. You could run it at 120Hz, but I don't think that makes much difference at all.

Make sure that your card can support that in the first place :)

I have noticed (with some monitors) that the maximum refresh rates distorts the edges of the view area. As for noticing a difference, I agree with with bushhead that you shouldn't be able see any above 80 Hz. However, a few people CAN notice a flicker at very high rates, and even get headaches from that. In general, I think stick to 85 - 100 Hz, unless you REALLY can see a difference (ask a friend or two for a second opinion).

As far as reliabilty goes, monitors usually have a much longer life-span than most of the other components, and thus I think you don't need to worry about that (Sony has an good reputation in this regard, anyway)

I'd say even a 70HZ rate would show no flicker,as long as it's non-interlaced.Superman wouldn't detect flicker at 80HZ.
Running at 120HZ is overkill,and probably will shorten the life of the monitor,specifically the horizontal output transistor,which will take most of the punishment.
