LG Oled. Best of the lot.
[This review was collected as part of a promotion.] Excellent picture quality, customisable to viewer preference. A real gem. On the pricy side but you get what you pay for. Reputation for quality. Look out for discount codes to soften the blow. Well worth it otherwise.

Amazing TV

Fantastic picture
[This review was collected as part of a promotion.] I love my new TV. It has replaced a 12 year old 32 inch LCD TV so is quite a step up, particularly with its OLED screen. The picture is quite stunning, even though I don't have any 4K sources. I also love the fact that Apps such as Apple TV and YouTube are bult in. With my old TV I had to get Apple TV using the browser on my laptop then cast it to my TV using Chrome cast - quite a palaver! I am still discovering all the features, and I think the remote control could be a bit more intuitive, but I love the pointer on the screen. I haven't yet found the best way to stop playback when I am watching TV through an App, but I am sure that will come with experience.

Great TV!
[This review was collected as part of a promotion.] I replaced a 7 year old TV (4k LCD) with this C5. It is night and day. Recommended!

The remote is awful
I love the tv.... But hate the remote. The EU remote is awful. Feels like it wouldn't last and does not respond all the time. I had the CX and it was a better remote.

LOVE MY NEW TV
[This review was collected as part of a promotion.] I love my new TV which was installed with ease into my TV bed. It's so light and thin. The picture quality is outstanding too. I'm not keen on the pointer option on the remote that I keep accidentally activating but I'm sure I will get used to it. A fab TV, no regrets!

Second LG Oled
[This review was collected as part of a promotion.] This is our second LG tv and have no complaints. The magic remote is amazing making it easier to use apps and search for content

Glossy surface
[This review was collected as part of a promotion.] Amazing TV, but with one downside, the glossy screen is highly reflective. Any light in the room shows up on the panel, which is quite distracting while watching."

OLED LG new purchase
Not our first LG but our first OLED. Easy to set up, picture quality amazing and whilst it doesnt really need a sound bar it does give extra life to certain films like they are coming out of the screen. Really happy with our purchase.

Fantastic picture quality
[This review was collected as part of a promotion.] The OLED screen was clearly the best 43" picture in store so after a long contemplation I went above my original budget. Got it home, got it set up and in situ the picture quality is even better.
