Has anyone tried something like this?

According to the comments, it'll shorten the life span of my laptop monitor. If anyone has done something like this, is it worth trying?

I tried it once, It turned out to be very blurry that I could not read texts normally. I reverted it back immediately

What kind of refresh rate did you have it set to?

It is not worth trying for a few extra hz.

I was able to get my old desktop monitor to run at 82fps from a native 75fps doing something like this, which is... kinda ok?

This is essentially a waste unless you basically have a nice laptop with a display panel that can natively run higher than 60fps, but for some reason isn't taking advantage of that.

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.

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.

If your laptop is using nvidia optimus it’s going to be a lot harder to overclock

I don't think there's much harm in trying, particularly if you only raise the Hz in increments of 5 less.
2 years ago I overclocked 3 60Hz dell monitors to 72Hz, and all three reached a hard cutoff before hitting 75Hz where they would say 'signal out of range' or something like that. In order to do this I found some timings specific to my monitor model online and used them in the Nvidia control panel while seeing how many Hz I could get. If you don't find timings for overclocking your laptop monitor then it might not be worth the time spent trying since without changing them you might not be able to get more than a couple extra Hz (and i have no idea what kind of magic it takes to come up with these timings).
It's also worth keeping in mind that using a custom refresh rate that has a small highest common factor with common media frame rates (e.g. 30 or even 24 fps) could potentially make stuff look choppy. That is why multiples of 12 or 15 Hz are commonly used.
If your display is 60Hz then using 72hz or 75Hz is a nice difference, and u can use sites like https://www.testufo.com/ to tell if the higher refresh rate is working properly. I would look for overclocking info specific to your laptop before u go any further.

I purchased an ASUS G751JY that i used the CRU on after reading up about it on blur busters forums. Many people were able to do this with little to no issues on this specific model. I was able to get one super cheap off eBay compared to the almost $2k 120hz Alienware models at the time. The default hz that came on these specific laptops was 75hz (included GSYNC as well), but i was able to OC it to 100hz and it was stable the 2 years i owned it. Once i sold it, i walked through the new owner on how to set it up and as far as i know he still has it running @ 100hz another 2 years later.

I would take the time to research the model you want to try it on beforehand - see if anyone has tried, what their results were, etc. Most times if you push a monitor past what it can handle, the screen will go blank and take you back to the "revert settings" screen. As HOI mentioned, going from 60 to even 72 is a nice difference...as was going from 75 to 100, but keep in mind you are still doing this at your own risk.

i tried going through the tutorial but I couldn't get the driver installer to install anything. So I went straight to the CRU step and everytime I tried changing the Refresh rate, it fucks up the resolution and the pixels and pretty much everything. Any1 got a solution?
