Re: C24FG70, Pixel Inversion?

Point taken.
The same can be said about things like viewing angle problems, strobe crosstalk, etc. Display imperfections are a fact of life...
Certainly can try exchanging monitor, but it needs to be at least warned that exchanging may not solve the problem -- depending on whether or not it's an intractable trait (like a contrast ratio spec, a viewing angle spec, etc).
Sometimes voltage precision specifications need to be 10x-100x more precise to make inversion artifacts below human detectability limits, as the positive voltage needs to be exactly the same as the negative voltage (right down to submillivolt levels -- the microvolts levels), which can be really tough when you're transmitting power down a grid of microscopic wires built into the panel that varies by several atoms in thickness throughout the panel...
But yes, some panel and monitor manufacturers do a better job than others.
Oh and yes, exchanging monitor could be worthwhile as a way of informing the manufacturer to make better monitors -- as long as accompanied with a big note -- "Inversion artifact issue -- please inform manufacturer directly about defect" -- so to increase chances that Best Buy (or even Amazon) actually sends the monitor back to manufacturer instead of putting it as Open Box / Refurbished sale -- and that the informed manufacturer is compelled to make inversion even more accurate to push inversion artifacts below human detection thresholds. Also, calling/emailing manufacturer tech support... to inform them about the inversion issue.
For this particular inversion issue I'm seeing it's relatively faint compared to even the best (least-inversion) VG278HE -- and certain other models. Sometimes worse than that Samsung photo is actually better than the normal for certain specific monitors with persistent inversion-artifact issues.
That said, inversion issues definitely need to be handled better by many manufacturers.
TL;DR: It may or may not be fixable by panel lottery. The user need to be informed to decide, at least.
