Burn in a new LCD

Thats interesting. On my experience the first couple of weeks are quite crucial for a new monitor in terms of developing stuck / dead pixels. For me, if the burn in procedure didn't prevent future stuck pixels, actually could show up monitor's faults before warranty expiration, wich is good too.

I see your "company or you and others" have been fortunate not to get any LCD's that have or develop dead or stuck on pixels. That's good, 20 out of thousands of others that do have pixel issues and the millions that don't.
Do you and others inspect these panels frequently with solid color patterns? I assume you know how to test them accurately.

"the manufacturing of LCD panels is pretty exact now and dead pixels are quite rare" ,
but in reality they are actually a common occurrence.

Your assumption is correct and very accurate.

For all,

Many others do end up with dead pixels in the first few weeks and it's a god practice to burn in the LCD as soon as you receive them, this is usually done at the manufacturers facility by some manufacturers, that's why some LCD's have burn in enabled by accident when the customer receive them.

Here’s a question:
For example, why do you think a burn in feature exists in the service menu of 2407’s in the first place? :)
Answer: So they can be burned in after the manufacturing phase is completed and possibly before they are shipped to avoid pixel issues, returns and complaints from customers.

If the manufacturer forgets to disable the burn in feature, as I've seen here from Dell occasionally, then they could also forget to burn in the LCD at the QC phase all together.

I would rather attempt to safe guard against dead pixels and stuck on pixels if at all possible.
Some don’t care how many dead pixels there are and just ignore them.

For those who don't like dead or stuck on pixels, burn in for a few hours and save possible grief from occurring later. :)

I use Dead Pixel Buddy 1.1. and the time cycle feature at the bottom of the list.

I also burn in and test for accuracy CPU’s with Prime 95 and system memory with memtest86, some of the ways to check for hardware defects and avoid issues in the future.

I like to get the best quality out of a purchase for my money :)

@all the facts: I have the idea of write down a FAQ for LCD's first time users on a spanish forum, and your idea surely will fit in it :P
Now, about the burn in feature, I've found that S-IPS pannels are really propense to develop image retention, so the burn in features can be there to solve this kind of problem?

Dell's FAQ has some good info.

I've read displaying a white screen for a few hours corrects pixel persistence or what's referred to as burn in, but we know LCD's don't burn in like plasma use to.

I may be confusing to some that burn in of a new LCD or CPU is not the same meaning as burn in as it pertains to pixel persistence. Two completely different definitions of the same term burn in.
