Well, i am on the other side of this question and as the adage "to each his own" goes, i would never, ever, purchase an OLED screen considering the many/many pictures posted by owners on the OLED sub-section for vignetting, pink/blue/yellow tinting, dark bands, image retention, burn-in, poor performance at near-black scenes, etc.
On top of that, i do not need to constantly and carefully "baby-sit" a TV due to my habit of pausing an image onscreen for too long and having to worry about permanent burn-in, widescreen bars burn-in, etc.
One owner that contacted LG about widescreen burn-in concerns from watching movies too many hours in a row with aspect ratio different than standard 16:9 and what could be done to mitigate the problem, reports the company strongly recommended to watch all video content in full screen only (standard 16:9 ratio), never mind those "pesky" widescreen bars of the original source !
Sure, those OLED blacks are fantastic and colors are amazing, but to me at the cost of too many variables.
Sure, LCD panels also have problems with dark bands and splotches but they appears to be related more to panel-to-panel variances than inherent to the technology itself, something i am not too sure about OLED screens after seeing those horrible pictures posted on the sub-section and what owners are willing to accept as "part of the deal".
I have owned a Sony 940E for almost two years now, watch it an average of 10 hours each day without any problems to report, use the pause button extensively and the set provides me with an amazing picture without any bands, dark edge corners, dead pixels, DSE, noticeable blooming, etc.
It displays probably best-in-class near-black low level detail, it is very/very bright and i certainly have not noticed any poor motion performance, as reported by some.
I would never consider replacing it even for a 77" OLED screen.
NO thanks !
