Sony A80J OLED vs Sony A80K/A80CK OLED: Main Discussion
What do you think of these products? Let us know below.
Looking for a personalized buying advice from the RTINGS.com experts? Insiders have direct access to buying advice on our insider forum.
Rtings literally posted this on the gradient score for the A80J: “When we originally tested the TV, it performed much better. The banding could be more prevalent because of general panel degradation, but we don’t know for sure.”
In other words, you say yourselves it may be caused by panel degradation (& didn’t update the score of the TV until late 2023/2024), yet when it comes to a Samsung TV with poor build quality out of the box, you don’t give it a bad score as say it may just be the one TV, even though Samsung has had issues with bent QD-OLED panels on it’s B & D series TV’s.
Hey there, thanks for your feedback! I’d like to clear up a few things in what you just said. The color banding on the A80J didn’t start 14 months in, it was always there, but our methodology changed, so it was retested. The scores on both TVs are also unrelated to the longevity test. Those tests started after we had already completed reviewing both TVs, and although it’s disappointing that the A80K failed, this doesn’t impact the scores as this sort of failure can happen with any TV. Our longevity test is designed to push these TVs the limits to look for failures, and one specific unit failing doesn’t mean that that specific model or even that brand is more prone to that sort of failure.
Your long term gradient score on this TV is ridiculous & unfairly measures it against everything else. Your comparison shows the A80K as being exactly the same as the A80J (To the point Rtings even wrote that both TV’s are so similar that buying either should just come down to which is cheaper). Yet the A80K is rated at 8.9 even though your unit completely failed 4 months in, while the A80J is rated at 8.7 due to colour banding which started 14 months into owning the unit.
The scores just make no sense.
