Custom low refresh rate = danger ?

[SephiRock]

Hello,

I recently bought myself a new monitor, an AOC Q27G2S, that plays at 1440p@165Hz maximum. It is G-Sync Compatible. I wanted to set it to 100Hz (yes, i know it sounds weird, but why i did that isn't the topic) but saw that this refresh rate wasn't proposed in the nVidia control panel. After asking friends, they told me that i could create a custom resolution in the control panel, to set it to 1440p@100Hz.
Yesterday, i was very sad to see that one of the pixels of my monitor appears to be faulty. I'll send the monitor back and take a new same one, but my question is : do you think that this faulty pixel could have been caused by me putting a lower refresh rate that wasn't initially proposed in the panel ? I've been gaming on that monitor for a bit less than 2 weeks, and i'm fairly sure this pixel wasn't faulty at the beginning. But since this display has VRR, it's supposed to be able to run at a lot of different refresh rates right..?
I just wanted to be sure those two things are unrelated, because i don't want my new monitor to have the same problem as the first one.

Thank you very much for your answers.

Failed custom refresh rate would result in either a flicker or a black screen, it shouldn't cost a dead pixel. I personally don't think it's related

Yeah i would think so too. From my understanding, only overclocking the monitor above its maximum refresh rate could eventually cause damage. In this situation, i set 100Hz instead of 165Hz soo... yeah.

What's troubling me tho is that this pixel doesn't really appear to be dead. It isn't black, nor white, the color just seems "off" and also changes depending on the angle i look at it. It first i thought it was some dust that was refracting light weirdly, but i'm sure there's nothing on the surface of the monitor. I cleaned it multiple times.

Lower down the refresh I don't think will impact to the panel quality. 

 

Higher up overclock wise I believe just will impact to the panel quality and lifespan.

Yeah it makes sense to me.

It sounds weird that lowering the refresh rate coule cause damage, espacially a random pixel going faulty.

 

But i'm being a bit paranoid because i wanna avoid further trouble with the new one, that's why i came to ask about people's opinion.

 

So far i was only witnessing people's comments on monitor pages being unlucky, so from my understanding it's purely luck based. It feels bad to be one of them now.
