Some interesting results, LCD performance degradation seems to vary much more between models than OLED degradation does

Here we have evidence of burn in on a number of LCDs tested

And a number of screens now have color shift and tinting. Their images are no longer accurate and the images have either become blue or yellow

At this stage in the test, 35% of all LCD screens tested have issues. Samsung is the worst offender with 50% of all Samsung TVs tested having develop image problems. Other brands that also have developed issues include Sony, TCL and Hisense

I did suspect this. My in laws television is unwatchable for tinting and it certainly wasn't like that when new!
 
That's interesting. My NU8000 LCD is coming upto 5 years old and doesn't appear to have a blue tint or any burn-in etc like the other Samsung 8000s in their list, but it is a better panel than those despite being older which might explain it.
Will have to get a grey video on it and see if I can notice anything.

It's certainly interesting that LED screens have issues as well.
When I was buying my OLED there was a lot of negative about the burn in. I haven't noticed anything yet after 12 months.

I have had my Panasonic 55GZ2000 OLED in my bedroom now for over 4 years and it has has over 6500 hours on it and it looks as good as day one
 
I've had my LG OLED55B7V for coming up to six years and it's got no obvious burn-in in normal use. There's some sign of it when a solid grey screen is displayed, but I don't tend to watch solid grey screens.

You wouldn't notice the tint anyway. As the video points out, it happens so slowly that your eyes become accustomed to it and you will only notice when you put another tv next to it and play the same content
 
That is some interesting findings.. Wonder how long before they start to address this problem to win the business back as this will get out there quickly..
Dissapointing to see Samsung being worst, but their approach to quality doesn't surprise me anymore - I've lost faith in that brand a while back.
 
I don't know if I can be bothered with watching the video all the way through - however, as people should know, "burn-in" with LCD's is not actually burn in, rather image retention.
All you should need to do is leave the screen powered up displaying a single colour for some period of time and it'll go away.
 
While not an image retention related issue, my 3 year old Samsung QLED is on its way out with a horizontal line across the screen with dithering and colour tinting below it. From what I've read, it sounds like the panel is goosed. Pretty poor for a 3 year old TV of that cost to pack in.

Get it replaced under warranty.

I have the same set. I'm at 6 and a half years and there is now very noticeable screen burn. :(
 
My last 2 Samsung LCD`s developed purple tinges at various parts of the screen. Was OK till the Skiing was on. :p
Swapped to OLED starting with the CX, and now have a C3 as well.

Funny you should mention a horizontal line, this has just happened in the last week to one of my old Samsung KS8000 TVs, it's got two horizontal black lines running across the screen that's visible in light content
