Dingbatt: PMed you.
Am I right in recalling that the '8' series LG OLEDs also have a
'logo removal' setting? Where it looks for a static logo and virtually blanks it out.
Since LG is top of my shortlist, I'm hoping the pixel refresh isn't going to be a problem. Having said that, the family are well versed in looking after screens susceptible to burn in, having had Plasmas for more than a decade. (First rule: No Gaming).
EDIT: @
Dingbatt I just changed the logo dimming setting form the maximum setting to "off" while watching One News. The solid part of the logo increased in brightness (noticeably, but not hugely), however the translucent part didn't appear to change at all. So the feature does do something on solid static logos.
