The MRGB88 is one of the more intriguing televisions in this batch because it does not price new backlight technology as a £3,000 experiment. Its separate red, green and blue light control aims to keep bright colours rich while Mini LED-style dimming manages contrast. LG also treats it as a practical living-room television with webOS, four modern inputs and a 144Hz ceiling. It still needs proof: colour accuracy, blooming and viewing angle decide whether Mini RGB improves the picture or merely the marketing vocabulary.

- You want to try Mini RGB below flagship prices
- The room is bright
- Several gaming sources need modern inputs
Skip it if…
- You require proven measurements
- Perfect dark-room black is the priority
- You want strong sound without a soundbar

A closer look, category by category
Picture quality
Mini RGB controls coloured backlight elements rather than shining white light through a colour filter. That should improve colour volume at high brightness. It remains an LCD television, so dimming zones, halo suppression and panel viewing angle still govern dark scenes.
Gaming and motion
LG specifies four HDMI inputs with 4K 120Hz features and VRR up to 144Hz. Dolby Vision gaming at 4K 120Hz is supported. That makes the connection layout easy for several sources, although measured input delay is still needed for a strict performance score.
Living with it
webOS 26, the Magic Remote and a five-year upgrade programme make the smart experience familiar. The 20W speaker system is the obvious weak point beside a large, high-impact picture. Unlike OLED, static interfaces do not create the same retention concern.
Price
The exact 65-inch LG MRGB88 was listed at £1,599.99 in the UK when checked on 1 August 2026. That 65-inch price is used throughout this review and by the buying guide; a cheaper 55-inch version cannot improve its value score. Prices and promotions can change, so confirm the model number and final basket total before buying.

Bright mixed-use room
High colour volume and LCD practicality are the intended strengths.
Multi-source gaming
Four modern ports and 144Hz support avoid obvious bottlenecks.
Dark cinema room
A proven OLED remains the safer contrast choice.
Where it sits in the market
Samsung's R85H uses a similar new idea at a higher price, conventional Mini LED models are better understood, and OLED remains the dark-room reference. LG's advantage is making experimentation less expensive.
How we reached this verdict
This research-based assessment uses LG's UK model documentation and exact 65-inch pricing. Mini RGB claims are explained but not scored as measured fact, leaving the model outside recommendations until product-specific testing exists.
