Perfect and very happy with the features
Best feature is the way my recordings are filed. I can also watch a programme from the start even though it has been on for half an hour or more.

Stunning picture in a great 48" size
I've been very happy with this 48" OLED. The picture quality is excellent with deep blacks, strong contrast and vibrant colours, and motion looks smooth for sport and movies. Setup was straightforward and the smart TV interface is quick and easy to use with all the main streaming apps. Sound is fine for everyday viewing, but you'll get a bigger upgrade with a soundbar if you want more impact. Overall, a great TV for a lounge or bedroom and I'd recommend it.
