You won't get a much better deal than this LG 55UK6400PLF 55 inch Ultra HD 4K television that provides the best of home entertainment at a good size and price.

Size matters and there's only one TV in the range that has more girth than this product, which is still remarkably lightweight at just 17.3kg with its stand.

All of the great features associated with the two smaller versions of the model are clear to see in this 4k set, without shirking on picture quality.

Its bigger size makes any viewing even more of an experience, with sets of 55 inches and above becoming all the more commonplace.

The screen resolution of Ultra HD 4K is four times more realistic than full HD and defines each pixel perfectly to make up a perfect picture.

There's no distortion from any angle, due to a surrounding 4K panel, meaning there will be no bad seats or black spots in whichever room the set is placed.

Advanced picture processing is handled quickly through a quad core processor that keeps all images sharp, from the first to the last.

Ultra luminance and dimming technology master the depth of any scene and is enhanced by Active HDR, which perfects the contrast frame by frame.

Expected an extended range of colours to be dynamically altered by 4k specific HLG that reacts to footage as quickly as you do.

It doesn't always require 4K programming, either, as standard FHD signals can be upscaled to a point where you can see and hear the difference.

Ultra surround brings sound to life by creating virtual multi channels which bring a fantastic audio experience to your household.

The television is HDR10 compatible, so you can get the best out of the latest consoles. Sony and Xbox players will be well covered by a model that is gaming friendly.

The LG webOS smart TV system is built-in and acts as a central hub, which is easy to use with a wealth of options.

It contains LG's app and content store, which makes streaming services simple to run seamlessly and opens the door to a world of material.

YouTube, Netflix, Now TV and Sky Store, to name but a few, are either ready to go or downloadable as are channels such as BBC iPlayer, the ITV hub, All4 and Demand 5.

More benefits of the LG 55UK6400PLF 55 inch Ultra HD 4K television: -

  • True colour accuracy - Rest assured you'll never be left in the dark with this clarity.
  • Clear Voice III - Pulls the speech out of background noise so you can listen clearly.
  • For the gamers - Four HDMI ports allow you to hook up multiple machines easily.
  • Access your apps quicker - IR controller's buttons go directly to Netflix and Amazon.
  • Make yourself heard - LG's Magic Controller and ThinQ AI TV are fully compatible.
