botan9386: Don't know a whole lot about monitors and wasn't able to find an answer on Google, maybe people in here have an idea.

I have two Omen 25i monitors, got them both at big discounts and they're solid IPS monitors. However, I noticed that when HDR is enabled they have different peak brightness. Doesn't appear to be a huge deal, HDR on these cheap monitors is mostly a gimmick anyways.

Monitor 1 - 500 nits
Monitor 2 - 486 nits

But I am wondering how this could be the case, is it normal for two of the same monitors to have this kind of difference?

twistedpony: I think it's just "manufacturing variance", which is to say that nothing can be physically manufactured to be 100% identical. There's only at most a 3% difference between those numbers. I think it's also why specs for monitors usually specify max brightness as "typical" values.

botan9386: This is what I suspect, just found it odd that there'd be a manufacturing difference on something like brightness.

dnovraD: Nefarious and nebulous things like monitor calibration. This is why print shops and artists often have to ask for expensive devices and special test cards, and exact lighting setups.

idbeholdME: Yeah, I suspect the issue could be mostly negated by calibration. Realistically, no piece of hardware is going to be 100% identical. Especially for something like monitors. Whether the variance is 0.3% or 3% is all luck of the draw, also known as hardware lottery. Mostly talked about when it comes to GPUs, but applies to anything really.

botan9386: I just also caught that my newer monitor is warmer in tone, I have adjusted the RGB levels slightly to make it cooler but if I were nit-picking I can still see the difference.

I can't imagine how annoying it would be for artists or photographers to get consistency across different set-ups.
