Vivid colours and a great picture
[This review was collected as part of a promotion.] This is hands down the best picture of any TV I have owned, the colours are vivid, the picture crisp and the connectivity to all my favourite apps is there.

Very happy with my new 77" OLED!
[This review was collected as part of a promotion.] In awe of of the overall picture quality and overall performance of this TV. Opted for 77” inch version and couldn’t be happier. Images are crisp and colourful when using HD & HDR services like Netflix, Disney+ etc and even watching TV is a treat. Gaming is sublime and find the TV works great with all my consoles and that high refresh rate is something else! Menus are snappy, with a great UI too. Overall you won’t be dissatisfied if you pick up this TV!

Awesome 10/10
[This review was collected as part of a promotion.] This TV has begun a new living room make over, I couldn’t wait to rip it out of the box. I have been an early adopter to OLED tv’s in fact this replaces a 2019 LG oled model that still is going strong with zero issues and looks and sounds amazing. For me the LG brand has stuck out and is the only brand I will consider when purchasing any TV’s This TV has the wow factor it is the centre piece in our living room everyone passes comment on it. I have worked had and proud of my purchase. The TV is more than a possession it will help carve memories in the house and I am sure it will give me many years of amazing viewing. The whole process of picking the TV from reading other people’s reviews and going to stores to fall in love with it is a whole purchasing experience in itself. Don’t just take me word about it this TV is stunning in every way, read the reviews and if you are in the market for this premium product just go ahead and purchase it

Blown away
[This review was collected as part of a promotion.] Purchased the LG 77 C5 to replace my LG 65 CX. Nothing wrong with the CX just wanted to go bigger. As I already owned a OLED tv I wasnt expecting a big wow factor as I did when I went from a LED. The C5 blew me away. The picture quality is awesome and colours are so strong and the blacks are blacks. With the older CX I had to close the blinds to reduce the glare, but what ever they have done to reduce the glare and make the screen brighter definitely works. Another issue with the CX was dark scenes it was sometimes hard to make out details but this is now not an issue on the C5. Sound is also a lot better on the C5 but I use a sound bar so this was something that wasnt going to change. The new opperating system takes a bit of getting use to, but is a lot better as you can customise more. The remote has lost a few buttons and is a little slimmer. In all honestly for such and expensive tv the remote looks and feels cheap, but you dont buy a tv for the remote. Last point a few changes to make straight away. Use film maker mode for all media and also switch of energy saving mode. You want the full brightness as thats why you paid for.
