SeltzerHas anyone tried something like this?

Yes, I've done this on laptops, korean monitors, setting up weird custom resolutions on 144Hz and my 240Hz monitor. And changing settings for a better Lightboost.
SeltzerAccording to the comments, it'll shorten the life span of my laptop monitor.
Probably not. For the most part you're not changing voltages are anything like that, but it's technically possible that you'll shorten the lifespan of the monitor, but it isn't going to be a whole lot shorter. For example I have a 1080p monitor that is rarely if ever turned off and is on for over 80hours a week I have pushed the refresh rate from 60Hz to 72Hz and it has been like this for 3 years now, this monitor was already in regular use for 4 years before that as well, no dead pixels or anything like that.
SeltzerIf anyone has done something like this, is it worth trying?
Depends on how well your monitor does with overclocking it's refresh rate, what you're trying to do, and how far you push it.
Black Screen, Flickering lines, really bad Blur are all signs the monitor is either being pushed to far or you put in the wrong settings.
Another note the further you push a monitors refresh rate from it's "native" refresh rate the brighter your gamma will be, giving you a much more washed out look. Usually only going 10-15Hz higher than native is barely noticeable but if you push a monitor to say 180Hz or 200Hz it'll look pretty bad.
_TannerIt is not worth trying for a few extra hz.
Wrong.
-edit-
Highly recommend connecting a 2nd monitor (that you don't change refresh on) if possible while doing this, will save you a lot of headaches and time getting the right refresh rate and settings.
