The C6 should be the easy recommendation: excellent black levels for films, four advanced HDMI ports for games, Dolby Vision and a smart platform that covers UK services. LG has also moved its higher Alpha 11 processor into this range and raised the gaming ceiling to 165Hz. The issue is not what the C6 can do; it is what the C5 already does for considerably less. Unless the new processor and brighter panel produce a visible, measured improvement, the outgoing model remains uncomfortable competition.
Buy it if…

- Dolby Vision matters
- The C6 price has moved close to the C5
Skip it if…
- The C5 remains far cheaper
- The room is exceptionally bright
- You are buying before independent measurements arrive

What's good
- OLED black levels and wide viewing angles
- Four HDMI 2.1 inputs
- Dolby Vision and 165Hz VRR
- Alpha 11 Gen3 processor
Worth knowing
- Expensive beside discounted C5 stock
- New performance needs independent confirmation
- webOS can feel crowded
- Built-in audio still falls short of the picture
A closer look, category by category
Picture quality
The C6 keeps pixel-level OLED contrast and adds LG's Alpha 11 Gen3 processor plus Brightness Booster. That should help tone mapping, upscaling and daytime impact, but the size of the improvement over C5 must be measured. Dolby Vision, HDR10 and HLG support cover the important UK formats.
Gaming and motion
Four HDMI 2.1 ports support VRR, G-Sync, FreeSync and up to 165Hz from a compatible PC. Consoles can use 4K 120Hz and Dolby Vision gaming without occupying the only advanced input. LG's Game Optimiser keeps the important settings visible.
Living with it
The thin, light chassis works on a stand or wall and webOS provides the expected services. OLED care is largely automatic for mixed viewing. Buyers should compare final prices rather than generations, because a C5 discount may outweigh the C6's incremental benefits.
Price
The exact 65-inch LG C6 OLED was listed at £2,099.99 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.

Mixed films and gaming
Few televisions combine format support and connection flexibility as neatly.
Gaming PC
The 165Hz ceiling is the clearest upgrade over older C-series generations.
Budget-conscious OLED buyer
A discounted C5 may deliver nearly the same everyday experience.
Where it sits in the market
Samsung's S90H targets glare and high-refresh gaming, LG's G6 is the brighter design flagship, and the C5 remains the dangerous value rival. The C6 must establish its lead through measured processing and brightness, not its year number.
How we reached this verdict
This research-based assessment uses LG's exact UK model specification and current 65-inch price. The new processor and brightness claims are not treated as tested results, so finder eligibility waits for product-specific independent evidence.
