If you're still thinking about it this much, just get it exchanged. Usually it's a UPS store drop-off. But there's sometimes an option for free scheduled UPS pickup. If you don't see that, just hit up their Chat and they will hook it up, no issues, I'm sure.
I still stand by what I said though. I agree if it's a monitor then I wouldn't chance it. This thing can't be nearly as sensitive all around if it's already working. They won't punish you for opening it and finding out first. These are the same people who sometimes credit you $5/$10 just because a package is 1-day late.
