Beautiful picture

Beautiful picture and simple to use. It's the first oled I've bought so can only compare it to lower spec tvs I've owned. Sound isn't bad either although we have upgraded to a soundbar to bring out the best. Only 2 weeks in so can't comment on longevity but so far very happy with the purchase.

Top telly

[This review was collected as part of a promotion.] Once I sussed out how to take it off store demo mode it was brilliant. They set everything as vivid as possible that it the picture is just too much and false. The AI picture setting function is totally brilliant. Top telly, and the sound is good too

BEST TV EVER

I saw alot of things online about OLED saying its the perfect image and they was not wrong. Straight out of the box this TV is unlike anything iv witnessed before, the compliments its has got from friends and family are also perfect, gaming is crisp with the 120hz display and the film experience is impeccable. Id love to see what the LG G4 was like but this was in my budget and i am very satisfied. TY LG life is good indeed.
