Rated 5 out of 5 by from 4K makes difference Very nice TV, have it for year now. Even SD content looks very good (upscaler does it job). DVR features are buggy so dont count on it. Disappointed with Smart Features, apps are removed one by one, while I expected more apps over time

Rated 3 out of 5 by from No flash player to watch videos via the web I thought this product was a Smart TV, however it lacks a basic feature, a flash player which enables videos etc via the Web. If I known that this feature was not available I would not have bought the product.

Rated 3 out of 5 by from good features but poor picture quality Bought this to replace my 4 year old Samsung which I was taking to my new holiday home. Have now brought back my Samsung and relegated this LG to the holiday home where it gets less use. The screen has a film over it that looks like it needs peeling off but the instructions say DON'T peel it off.

Rated 1 out of 5 by from Poor product broke after 2 days We bought this TV with great expectations. It was perfect for us - right size, features and great price. We went to buy it and found there was only 1 boxed TV left in Scotland - in Elgin, which we got. Got home got it all hooked up - perfect! 2 days later we go to turn it on and it won't switch on. Tried everything, looked it up on the Internet to try and fix it, nothing worked. Took it back to Curry's, they tried it and it didn't work. Our old TV was a Panasonic, and we thought we would give LG a try. We got a refund for the TV and have gone back to Panasonic, which is more expensive so we weren't able to get all the features we wanted but at least we know it's good quality.

Rated 5 out of 5 by from We love our new TV! We were torn between buying a 55" or the LG 49" so we decided to go a little smaller with this one. It looks great in our lounge. It has been great so far.

Rated 5 out of 5 by from 4K at a price that wont hurt the wallet! I have been sat for ages, waiting and watching the price of 4K TV's for a while now, well over a year and when I saw the price on the LG 49UB820V I went straight to my local shop and picked one up. As with all things I like to make a bit of an effort knowing what I am about to buy, reviews were good and in store viewing was impressive. Once home I was like a kid, my last TV was an LG Full HD 42" and never had issues with it, thus going the next level up I trusted LG fully. Once fully setup, which was easy, it was no different than what I had seen in the store, 4K files I had downloaded were crisp and played through the USB with no issues and wowed the people who I have showed. The upscaling is great for SKY HD and can see the difference, the PS4 looks better, but with no 4K gaming this gen of consoles, I know I am ready for the next or fireware upgrade - fingers crossed. Sound is ok, but have a soundbar and put the TV through that for good measure. The screen goes right to the edges, with a 3mm surround only and is nice on the eye. Features are ok as a smart TV, not really used the apps, but the connection to mobile devices is a nice added touch to show off your videos from your phone or tablet. Over all I am very impressed with my purchase, more 4K stuff will come out soon I am sure and can't wait :D
