Using monitors at not supported frequencies

I have a Mag 996PF witch has served me well. I don't have the chart that lists each resolution and the max refresh rate for it and I can only rely on what the driver tells me the monitor supports (Display properties -> Settings -> Advanced -> Monitor). I want to run 1280x960 @ 100 HZ but the box shows me that I can only go as high as 85 HZ. If I uncheck the "Hide modes that this monitor cannot display" I can select 100 HZ and the screen works fine and doesn't flicker at all. My question is, before I start using this freq., is it good for the monitor or can really "lead to an unusable display and/or damaged hardware"?

ONLY GO AS HIGH AS 85

are you absolutly cray 85 is so fast its mental to even try go at 100.

you shouldn't see a differnce, i used to use my monitor at 85 because i thought it was better than 75 or 65. well i bumped it down to 75 and havn't noticed a difference.

the faster the refresh rate the shorter the time your monitor lasts.

personally i wouldn't even attempt going faster than what the box says, you would void a warentee, and risk somthing that isn't even worth it.

You are crazy not to notice the difference between 85 and 100, at 1152x812@100 it's possible to concentrate when reading a lot of text but at 85, I wouldn't describe it as flickering, but unstable image. 100 flickers as much as a picture on the wall, 85 doesn't.

nope to me 85 is as solid as anything 75 flickers only a tiny bit if you move your eyes very very fast.

but hey thats an opinion of mine, the older standard for flicker free was 72 and is basicly what most people stop complaining about.

i can tell you the refresh rate for any monitor just by looking at it, but at 85 for me its solid but hey.

i just wouldn't risk setting it to 100Hz, anyway the fact is that the phosphor on the screens has an afterglow effect meaning that there is a point at which the image truly does become solid due to the time the phosphor is glowing for, so it potentially is different for different monitors.

I was previosly at 1152x812 @ 100Hz by selecting it from the refresh rates my screen supports, so 100HZ is supported, only not at 1280x960

yes thats the same with my monitor.

mine suports 100Hhz (i think even up to about 120Hz) at about 1024 x768, however at 1600x1200 i can only use 85Hz max, and then again i only use it at 75 to save the life of my monitor for a bit.

the problem you face is that at 1152x812 at 100Hz it scans the screen 81,200 times per second e.g. from left to right that many times, it scans moves down a line then scans again etc...

however at 960 at 100Hz it scans the screen 96,0000 tims which is about 120% of the first, at 85Hz it scans 81,600 times across the screen.

so effectivly 1152x812 @ 100Hz ~= 1280x960 @ 85Hz

its just simple maths.

as for the verticle refresh rate thats another calulation that i don't feel i need to go into as i think my point is obvious.

p.s. do what you want to do but remember its your monitor your risking, you have bypassed the security features they have in place, ignored a warning screen saying you may damage it and have not listened to the instruction manual as well as me, so basicly your on your own for this one from now on. it seems you are determined to do it.
