Which one to Buy? AOC Vs. LG

If the specs are on par with each other, I look at the warranty, and both of those have 3 years, so even that is the same.
As you say, the LG stand is in-your-face but it's adjustable, I couldn't see where it mentions that the AOC is, so assuming it's not.

As to ghosting or burn, that was an issue with CRT monitors, I've never seen any LCD show the same effect. Maybe it happens on lesser quality LCD's.
It was only seen on CRT monitors that had the same image (or one that seldom changed) displayed all day every day, so places like shops, retail outlets, reception rooms, where they would have a continual slide show of ads, or marketing images. And it took years to be visible, when the monitor was off.

Burn was when the electron ray guns in the CRT fired their beams at the same spot on the phosphorous coating on the inside of the front glass.
Once that coating was 'burnt' it would never go away.
LCD's are different in how they output their light, 3 LED's are used to make one pixel change colour.

For personal use, I doubt you'd ever get the same effect, the screen is simply never showing the same image for long enough.

@Dezs - you logged in yesterday but haven't updated - still need help?

Up to you of course, and all the best with your choice. 🙂

I've never see burn-in on a personal use monitor, and never one on a LCD type.
I also cannot remember the last time I saw a dead pixel.

Will closed for you.
