Dead pixel on AH-IPS matrix?

Question

Do it yourself

There is a LG 23EA63T monitor, which is 3 days old from the date of purchase. Noticed a dead pixel. Highly visible on a white background. The pixel is black. Is it possible to do something with this or is it better to carry it back to the store until 14 days have passed?
And what better to say, because 1 dead pixel is not an excuse for replacement, but returning the goods as high-quality and normal seems to interfere with the broken pixel.
I read on the Internet about freezing, about finger pressure, and so on, how applicable is all this for AH-IPS matrices?

Answer 1

In general, "complex household appliances of good quality are not subject to exchange and return." Some sellers go even further and accept returns, but on the condition that "all packaging is preserved and no signs of use."

Answer 2

I wore three different colors. Here, how to agree with the seller, he is not obliged to change in this case. But you try, take it.

Answer 3

The seller, by the way, can refer to the manufacturer: LG LCD Monitor Pixel Policy . LG allows up to 6 dead pixels.

Answer 4

I've been thinking... If there is a trend for higher resolution monitors (such as 250ppi), then soon manufacturers will howl at the number of returns. There are much more pixels in the matrix itself, which means there is a higher probability that at least three of them will be broken.
