Quality TV
[This review was collected as part of a promotion.] I’ve had this OLED for a month and it’s a substantial upgrade over my 55B9 The colours are rich but natural, it has deep inky blacks. Very pleased with my tv, but I know I’m being harsh but I would deduct half a star as the remote is fiddly and not as good as my previous one.
Clacky, Milton Keynes

Great features!

AXN_LGTV
A superb high-end TV packed with features
[This review was collected as part of a promotion.] An excellent choice for a small to medium room, this TV is beautiful to look at and moreso to watch content on. The settings need tweaking to your personal taste but there are options aplenty to enable this.

Great screen but you might need a soundbar
[This review was collected as part of a promotion.] Huge step up from my old Sony edge lit TV albeit the sound isn't as good (a common problem with tvs that have things screens). Dolby vision is great and not supported by a lot of manufacturers. Just be prepared to alter a few settings to get the picture to your perfect viewing experience...
Enny
Superb OLED Model
[This review was collected as part of a promotion.] I haven't actually installed this exact telly yet as it is a present, but having used the same model previously in the bigger 65" variant, I know that I am going to be happy with it. The colour reproduction is superb in movie mode and the interface is easy to use. If you haven't used an OLED TV before, prepare to be blown away. I can't wait to watch some BBC Earth on it.
