Picked this up for £750 in a flash sale a few months back to replace a Samsung TV with about 17 blown back lights.
This TV is light years ahead of that. The picture quality is out of this world. Lovely slim design and a great UI that works quickly and consistently.
Highly recommended!

When i first bought the tv, it was ok. with each update it became full of “sponsored content”. Now when you leave it idle for a few minutes, instead of a screen saver, it shows ads. what is the service i am receiving so that i need to see ads in order to pay for? nothing

Not a bad tv but is a bit dark. Happy it has chromecast, fast, overall good quality.

For price and quality, this beats competing products hands down – I know because I’ve owned them too!

this oled is very good contrast and great whites and deep blacks colours are good only thing is it is darker viewing no matter how max brightness etc is set. tv is a good entry into oled and plays games but on xbox looked abit darker. but expensive oleds will do better and brighter im sure. mini leds ive seen do make things look more pop n colour but oled does beat in blacks and contrast. im lucky i have both so i can compromise for games and movies. im happy for great sharp picture from lg oled so i gave it 5 stars and is my first into this tech. this should keep well until new rgb mini led arrives and cheaper which should match oled or very close to in future from what ive seen. if anyone wants the best out of lg oled may need to pay for more.

Got this TV for our family room after my 8 year old LED TV gave up the ghost. Really impressed with the upgraded visuals and sound. The menu is easy to navigate, and I like being able to customise the gaming mode optimiser, especially the blue light reduction. I also really like the quick app access feature you can programme to the numbered buttons on the remote – very nice touch.
