Exactly that (but that would be extreme if that example occurred)
Not experienced any problem with gaming to be honest. Sports channels and news channels with fixed banners are the main culprits. But it doesn't last on the new models.
Juts takes a bit of thought and care.
If you do get a high spec TV please take the time to set it up properly too. Never ceases to amaze me how many people buy decent TV's and then leave them on factory standard settings, which are universally poor.
LG C7 or Sony A1 for me, but the A1 isn't quite as future proof (yet) and isn't great on SD content.
When you game, what is the longest you have been playing before noticing some kind of Image Retention?
Or when you watch a movie with black bars, do they stay after the movie?
Im so fucking scared of IR!
My Plasmas were a nightmare, i just couldn't play videogames without the thought on my head of burn in.
I had the same problem with my panny plasma when TV was still mostly 4:3 content. The black bars on the side were clearly a different shade when actual 16:9 content came on. I set it to zoom for 4:3 content and after a few months it was finally not noticeable anymore.
It's not only the burn-in that kept me back from OLED. Longevity is a big one as the tv is used by everyone and can be on more than 10 hours per day. OLED screens fade over time to 50% brightness from day 1. Also ABL didn't sound that great. C7: Good HDR peak brightness, a little brighter than the LG B6 and C6. Although the TV gets very dim when showing a pure white window due to its Automatic Brightness Limiter (ABL) I'm pretty sensitive to these light output changes, distracting.
We from LG say burn-in is not a problem. Hmm yeah.

The C7P OLED TV is prone to image retention just like previous models. Fortunately, the image retention is less strong than what we have measured on 2016 LG OLED TVs.
If you find out that your TV has some image retention after playing video games over a long time for example, there is a function in the 'Picture settings' page, under 'OLED Panel Settings' named 'Pixel Refresher' that will 'recalibrate' the screen to get rid of any imprinted images that may still visible. This procedure lasts around one hour and the TV needs to be shut off for it to work. This can usually take care of any image retention.
Another feature is also available on the same settings page named 'Screen Shift' that will 'move' the screen slightly (you can't really notice it) to make the image retention less problematic. For our test, this feature was turned on but there is still some image retention.
Anyway the price made the final decision as I could afford the 65" 900E. 65" C7 was out of my range and frankly not worth the price difference imo. If it was just for watching movies in a dark room, I would go for OLED no doubt. Yet as a general purpose tv, I'm very satisfied with LED. OLED in PSVR looks great though!
