I’ve heard nanocell is trash from some forums. Colours and picture aren’t that great. And I think it’s an IPS panel as well, so washed out colours. Definitely go for an OLED or QLED rather than this. But I’m not sure how the new LG 8K Nanocell TVs are like.
Should be Oled Vs LCD. Nanocell is just another fancy name just like Qled,Uled...there is plenty info about Oled Vs LCD on the web. Both have their pros and cons and the choice is up to you (y)
Oled vs nanocell - what are people opinions about quality and longevity?
For this sort of price you can get the 75" Sony XG95 which doesn't have the extreme resolution panel but has better picture quality in more noticeable aspects. LG's more 2020 LCDs are also rumoured to have improved quite a bit at the top end so while the NANO99 is currently the same price this was eight months ago, if you're specifically after an LG LCD and in no hurry it might be worth waiting.
