Customers Say
LG OLED C5 TVs deliver stunning picture quality with deep blacks, vibrant colors, and excellent gaming performance. Sound is generally good but some users report issues. Interface is feature-rich but can be complex.

Unbelievable upgrade
[This review was collected as part of a promotion.] Going from a 2017 Samsung 4K TV was always going to be an upgrade but the upgrade to OLED is breathtaking. I bought the C5 primarily for gaming, which is fantastic with the game optimiser, increased refresh rate and HDR. After upgrading Netflix and Disney+ to let me watch Dolby Vision shows, I honestly can't imagine going back to an LCD/QLED TV. The blacks are fully black and even in dark scenes you can see every detail. Whilst it's quite a price increase over a QLED/lower price point MiniLED, the difference is immense.

Happy with my Purchase
[This review was collected as part of a promotion.] We already had a Freely box (Manhattan Aero 4k) and Sonos Beam 2 setup. I was looking for something that would give an excellent quality picture and sound. We no longer have a tv aerial (reception here is poor, especially in the summer) and so I cannot comment on broadcast live tv. I have to admit that I had not realised how much bigger this screen would be (we had a 40" Panasonic before) and I have come in for some stick from my wife who has always said that she did not want the tv to dominate our living room. However, we have both quickly got used to the new size and it does mean that we can watch from further away in the room as well as close up. There are a lot of settings to try out and it has taken a while to find what we like best, but that is to be expected. I am very pleased with the depth of colour and contrast that the OLED screen provides. UHD on BBC iPlayer for looks superb. Dolby Vision and Atmos is equally good from Amazon Prime. Playing Mario Kart with the grandchildren works better with a four-way split on the bigger screen. I bought direct from the LG website at the lowest price I have seen. It arrived promptly and was easy to unpack and connect up.

Great if you can get a good deal
[This review was collected as part of a promotion.] Best picture in a 42 inch. Strange no Freely. Use a soundbar

[This review was collected as part of a promotion.] Excellence picture. The pointer is annoying as it is difficult to control. Forces you to use the up down arrows which start off in the wrong place

Overloaded.
The picture and sound are excellent. That's as far as it goes. The TV is loaded with apps and loads of programs which I don't want. Setting up is relatively easy. No Teletext is a mistake by LG. If you want loads of apps ect it's a good buy. If not, look elsewhere, and save money.
