why some of people like to quote "some says", "i heard someone says" or "i read from"

i know you are going to buy an expensive items, but you will not know unless you see it for yourself.

of if you need to test it 1st, you can go to a showroom that displaying all the models. you can test it for yourself.

in my experience i exchanged my current led monitor twice. the 1st one had scratch on the screen, the second one had dead pixel. right now i am using the 3rd one and it is perform well until now.

my point is, you will not know what will happen before you buy it.

based on the article, they said to pressing the top 2 buttons for 5 seconds before switch on the monitor. after that pressing the top button will launch the factory settings menu with a blue background.

unfortunately i do not know how to save the setting. everytime i change the factory setting like colortemp, overdrive, and go to exit, it will revert to the previous setting.
