Experience the benefits of full array local dimming on the LG 55SM9800PLA 55 inch Nano Cell 4K UHD Smart Television.

LG's SM9800 models call upon FALD to control brightness levels with precision, with the nano cell display complementing that with brilliant colour.

Rows of LEDs fill the entire back-panel of the TV to create a lighting area that is divided into clusters of dimming zones, which can be turned on or off at will.

This can create deep dark colours, near-perfect blacks and peak whites, with a colour filter applied through light absorbing material.

LG's most-advanced LED TV calls upon nanoparticles, which are one nanometre in diameter, so that colours naturally shine through from the LCD display.

These nanoparticles are colour purifiers that retain their clarity at angles of up to 60 degrees and block unnecessary rays, from household lights and sunlight.

The IPS panel has true colour accuracy, with the in-plane switching organising the molecules of the liquid crystal layer to project over a billion colours superbly.

Reproduction of moving images is supported by a host of high dynamic range formats including LG's own 4K Cinema HDR, Advanced HDR by Technicolor and HDR10 Pro.

Additional remastering for live broadcast is supplied by Hybrid Log Gamma (HLG), which can adapt to differing light displays and correct any imbalance.

The television is powered by the A7 Intelligent Processor chip, which has artificial intelligence capabilities with deep-learning AI for picture processing.

The AI also comes to the fore to effectively sync audio from the down-firing 2.2 channel surround sound, with digital management through Dolby Vision and Atmos Cinema.

Upscaling calls upon an AI algorithm to optimise picture and sound and improve lower definition content to a near 4K standard.

Video streaming is commonplace on the webOS Smart TV platform with Netflix, Prime Video and YouTube already present and more available through the LG app store.

There are 10 picture modes to choose from including HDR effect, Technicolor Expert, Game, Sports, Cinema, Vivid, Standard, Eco, Dark Room and Bright Room.

Connectable devices can be managed through the user interface and the 4K HDR gaming boasts low input lags, reacting as quickly as the players do.

Motion Pro inserts a black frame between every other for flowing gameplay, with the 4K HFR high frame rate updated via HDMI.

There's a real creditability about the beautifully-picturesque Gallery Mode, which includes travel photos that are updated seasonally by TripAdvisor.

Rated 4 out of 5 by from SM98 - Decent TV Paid £900 for the 55inch SM9800 last week so it's still pretty new. Out the box it feels like a premium tv compared to my older lg its replaced, it has a good weight to it and a silver metal finish around the sides. Mine is mounted and it looks awesome, going from a 47inch I had considered 65inch but 100% made the right choice at 55inch. It's a big tv. Sound I am really impressed with, good base to fair and can get pretty loud. Picture is overall good but I can't for the life of me reduce jiddery blurry images, real shame as this wasn't an issue at all on my 3/4 year older tv. This isn't an issue at all when playing on the ps4 or xbox though so its totally weird and a bit annoying. The colours are great and can make some really pretty and vibrant images. Full array dimming is a bit naff mind. Overall I'm happy I picked this tv even if it does have some flaws.
