refresh rate on P991

Question

I have a P991 Monitor that I enjoy setting the refresh rate as high as it will support, 120 hz. Will this have any adverse effect on the life of the monitor, or is there an optimal refresh rate to set at that  will ensure maximum stabilty?

If you use optimal rates, the monitor will run cooler and the picture will be clearer than using the 120hz rate. I tried the 120 hz on my Sony, just softens the detail. Just try various rates, and pick the lowest one that is flicker free without blurring. The monitor will run coolest if the image flickers, like 60 or 72 hz. I use 85 hz 1024 by 768.Cooler running should last longer.
