Post by: buzztiger on September 11, 2019, 11:40
Do you guys test LED tv for dead pixel with test pattern when TV is delivered ? Or just test with normal TV channels ?

Easiest is to bring up a primary Color (RGB) test patterns for easier spotting of any dead pixel.

Yes. Totally changed 5 sets but still has at least 1 dead pixel or dark cluster or bending issue, until LG call me and told its normal and <3 dead pixels still within their spec. I actually still want to change but had felt tiring, thus i accept the last set they sent, with less bending, no dark cluster and only 1 dead pixel.
I suggest who has OLED should check with this green pattern and 5% dim screen, many funny things will discovered.

Sometimes ignorance is a bliss. Seen already cannot be unseen. :p
