Chriswand
OLED 65" TV
[This review was collected as part of a promotion.] LG were an absolute joy to deal with during the online order and purchase process. Great that there is no hard sell or annoying up-sell choices to make on the customer journey. Also, the fact that the price was very competitive when purchasing direct and I could not have been happier with the quick speed of delivery and their communication surrounding this process. Max 5 stars is not enough I'd give a rating of 6 stars!!

Great TV with one quibble
[This review was collected as part of a promotion.] Brilliant picture, excellent sound, simple set up, user-friendly interface. Bit disappointing that Freeview Play not available though
User26751, Hertfordshire
One of the best
[This review was collected as part of a promotion.] Worth it if you can afford the price. I upgraded from a C1 and the difference is clear. The C5 is noticeably better in brightness and colours. The only thing I noticed is that the sound is not as good compared to the C1. In cinema mode the C1 is more bassy and fills the room. The C5 is better in AI sounds compared to the C1. Overall, well worth the upgrade

Superior picture and sound.
[This review was collected as part of a promotion.] What a difference 5 years makes. The quality of both picture and sound vs our old Lg is dramatic.

Fab
[This review was collected as part of a promotion.] The picture quality is second to none — deep, inky blacks, vibrant colours, and incredible contrast make every scene feel lifelike. Whether watching movies, gaming, or streaming in 4K, the clarity and richness of the display are outstanding. Motion handling is silky smooth, and HDR performance is breathtaking, bringing out every detail even in dark scenes.

Great picture. OS a bit confusing at times.
[This review was collected as part of a promotion.] The picture is amazing, which is mostly what I care about with a TV since I use a cinema surround box for sound. I can't comment on the sound because I bypass it. The only grip is the UI is not intuitive. For example, I don't have an antenna or cable connected, only satellite but I cannot disable these inputs and if I view LG Channels, it is not obvious how to get back to viewing satellite channels. I need to choose guide, then filter and select satellite! Since satellite channels is my primary use, it seems odd that I don't have a one-button option for getting back to satellite channels from the home page view. Similarly, some of the settings to setup things are buried in obscure menus and difficult to find. I've had the set for 2 weeks now and have got used to where to find things and overall I'm very happy with the TV.

Pleased I went for LG
[This review was collected as part of a promotion.] So far I’m extremely pleased, huge difference in picture quality compared to our old TV, the colours just pop out and look way sharper than other OLEDs I’ve seen, very happy. I was in two minds between this and a Samsung, a mate got the Samsung and having seen both I recon the C5 is much better.
