It's LCD/LED's turn. Rtings longevity test update

[Grim5]

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

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.

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

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.

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

My last 2 Samsung LCD`s developed purple tinges at various parts of the screen. Was OK till the Skiing was on.
Swapped to OLED starting with the CX, and now have a C3 as well.

This is part of the natural color shift that happens on LCDs as they age - as the screen becomes older it loses brightness and the color accuracy falls off the cliff. Most people don't notice the changes because they happen slowly over a number of years, one of my qled TVs has a tint as well only visible in white or light blue backgrounds

That's why Rtings longevity test for LCD I believe is very important, people buy TVs based on reviews of how that TV performs when its brand new and that can be very different to how it performs 3 years later and would the customer have bought if you told them this would happen? OLED may have burn in risk, but they don't lose brightness and they don't lose color accuracy
