Increasing Refresh Rate To 100Hz On A 15" CRT (1 Viewer)

[Chuck C]

My buddy's 15" monitor had a wicked case of the flicker-bug. I looked at the Settings and the video card was set to "optimal". I changed it to 100Hz, and the flicker went away....can such a relatively high setting do any damage?

What are the monitor specs? Not all monitors can sustain that high a refresh rate.

If it syncs, it should be OK, but not necessarily. My monitor will sync above it's recommended range and eventually has problems. For that size, if the res. is higher than 800x600 I would try knocking it down to 85hz or below. There shouldn't be any bothersome flicker at that point.

Of course, if you have the manual handy and that refresh rate is within the specs, don't worry about it at all...

I'd set it to the lowest refresh rate where you notice no flicker.

My monitor is rated at 100hz @ 1600x1200 but when I change it to that setting the text is slightly blurred. So what I do is lower the refresh rate to 85hz which still has no flicker and the screen looks crisper.

An easy way I found out to notice flicker is look at the screen from the side of your eye.

I can only assume that running it at a higher refresh rate will lower the life of the monitor similar to running a brighter color setting. Probably not much though...

I fried a PB monitor this way but then it was a PB...

There ARE monitors that don't have a fail-safe circuits for driving out of range, but assuming this is a new monitor it shouldn't be too much of a worry.
I've killed a couple of cheap/older monitors in X-Windows before with some typos.
