I haven't been around in ages, but thought I'd follow up on my experiences with burn-in (or lack thereof).

I'm still using the same display (a Panasonic TH37PWD5UZ) in the same way, and the wear is essentially the same as I described in that four year old post. It's only noticeable to me because I know what to look for, and when to look for it. My family and friends don't notice it unless I pause a
very bright screen (say the opening panoramas of the shire in
Fellowship of the Rings ) and point out how the edges of the screen are
slightly less bright than the center square.
I've never done any sort of "break-in" other than turning the brightness settings down from "torch mode" to something appropriate for my living room. I watch things in OAR (albeit with grey side bars).
It's been a wonderful display for these past five and a half years, and I don't regret anything about it. And back then, these things cost three times what they do now.
Hopefully this tale will be a comfort to someone.
