replacement TV

[This review was collected as part of a promotion.] Not had long so will update more further down the line, but first impressions it a very good Tv, setup is a bit hit and miss, but take your time and you soon find out what each thing dose, great colour, and for some reason feels and looks bigger than my old TV, even though they are the same size, don't figgier, sound through my amp, is well above what the old one was, quality is perfect, clear vibrant sound, Neighbours must being doing there nut, could have done with 4 HDMI slots but you cant have everything, will like I said update on its quality further down the line when I've had it a few months, the price was well within our budget, so good value for money.

Good picture at a great price.

[This review was collected as part of a promotion.] I purchased this TV for the living room. It's mounted on the wall and we watch it from a distance of about 3m. It produces good vibrant colours and contrast. The user interface is easy to use. There are three hdmi sockets, we use one connected to a Sky puck and a firestick. The hdmi port that is an eArc port connects to an LG soundbar which we ordered after. As we previously had a soundbar we did notice a drop in sound quality from the built in speakers, however the new LG soundbar improved the sound and supplies 5 channel surround sound. Overall I'm very pleased with the picture quality especially on such a large TV. The price for this quality makes it a good buy.
