Samsung vs LG 65-Inch TV UK: Which 65" Should You Buy in 2026?

Updated 2026-06-25

At the 65-inch screen size, Samsung and LG dominate UK living rooms — and both make a compelling case for your money. Samsung's flagship QLED panels deliver breathtaking brightness and vivid colour, particularly in bright UK living rooms where sunlight can wash out darker displays. LG's OLED technology counters with perfect blacks, infinite contrast, and a wider viewing angle that suits open-plan spaces. The 65-inch sweet spot sits at £799–£2,499 in 2026, with clear tiers: Samsung's 65-inch Q80D QLED around £1,099 and LG's 65-inch C4 OLED at approximately £1,499. Samsung wins in bright daylight viewing and peak HDR brightness, LG wins in cinema-quality contrast and gaming response time. The right choice depends on your room lighting, viewing habits, and whether you prioritise HDR punch or pure picture depth. This comparison covers the most popular 65-inch models from each brand, breaking down every spec that matters for UK buyers including energy efficiency under Ofgem's current pricing.

Pros & Cons

Samsung 65-inch Q80D QLED TV

Pros

  • Outstanding peak brightness (~1,500 nits) handles bright UK living rooms without washed-out colours
  • HDR10+ Adaptive adjusts tone mapping in real-time based on room light levels
  • 4× HDMI 2.1 ports cover PS5, Xbox Series X, soundbar and streaming box simultaneously
  • Tizen smart platform is fast, intuitive and receives regular software updates

Cons

  • VA panel has narrower viewing angles than LG OLED — colours shift beyond 40° off-axis
  • No Dolby Vision support (Samsung uses HDR10+ exclusively, which fewer streaming services support than Dolby Vision)

LG 65-inch C4 OLED TV

Pros

  • Perfect pixel-level blacks and infinite contrast ratio — cinema content looks reference-quality
  • Dolby Vision IQ support covers Netflix, Disney+, Apple TV+ and more UK streaming services
  • 120Hz native panel with 0.1ms response time — the best gaming TV experience at 65 inches
  • Wide 178° viewing angle suits open-plan rooms and off-axis seating

Cons

  • Lower peak brightness (~1,000 nits) can look dim in bright south-facing UK rooms during daylight
  • OLED burn-in risk with static content (news tickers, sports scoreboards) over extended periods

Our Verdict

For most UK buyers, the LG C4 OLED is the better 65-inch TV if your budget stretches to £1,499. The OLED panel's perfect blacks, superior viewing angles, Dolby Vision support, and near-instantaneous gaming response time outperform Samsung's QLED in nearly every real-world viewing scenario. Choose the Samsung Q80D if you have a bright south-facing living room where peak brightness matters most, or if you want to spend £300–400 less without sacrificing much in a well-lit room.

Buying Guide

  • 1Measure your viewing distance before buying a 65-inch — the ideal viewing distance is 2.0–2.7 metres for 4K content; too close and you'll see pixel structure, too far and you lose 4K detail
  • 2Check your room's ambient light — QLED (Samsung) outperforms OLED in bright rooms; OLED (LG) wins in dim or controllable-light environments
  • 3Confirm HDMI 2.1 ports if you own a PS5 or Xbox Series X — you need HDMI 2.1 for 4K/120Hz gaming; older HDMI 2.0 caps at 4K/60Hz
  • 4Compare energy ratings — UK energy labels now show estimated annual costs; an A-rated TV can save £20–40/year versus a D-rated model at Ofgem's current 24.5p/kWh cap
  • 5Register your TV's warranty immediately — both Samsung and LG offer extended UK warranties (up to 5 years) when registered online within 30 days of purchase

Editor's Note

UK reviewers consistently rank the LG C4 as the benchmark 65-inch TV in 2026 for cinephiles and gamers alike. The Samsung Q80D punches well above its price in bright rooms — reviewers specifically note its Adaptive HDR performs better than expected in north-facing UK rooms with inconsistent lighting. Both carry 5-year manufacturer warranties when registered on the UK portal, which is worth doing immediately after purchase. Energy consumption: both qualify for A to D EU energy ratings; the OLED typically draws 10–15% less power than QLED at typical viewing brightness, a meaningful saving at UK energy prices.

Frequently Asked Questions

Is Samsung QLED or LG OLED better for a bright UK living room?
Samsung QLED wins in bright rooms. The Q80D reaches around 1,500 nits peak brightness versus LG OLED's 1,000 nits, so it maintains vivid colours in sunlit south-facing UK living rooms. LG OLED is better for darker or blacked-out rooms where contrast matters more than brightness.
Does LG OLED have burn-in problems in 2026?
Burn-in risk is real but rare in typical UK home use. It mainly affects displays running static content for 8+ hours daily (e.g., used as a PC monitor or showing rolling news). LG's 2026 C4 includes built-in pixel refresh cycles that significantly reduce risk. For normal TV watching, burn-in is unlikely within a 5–7 year ownership period.
Which is better for gaming — Samsung or LG 65-inch TV?
LG C4 OLED wins for gaming. Its native 120Hz panel combined with 0.1ms response time and VRR support (HDMI 2.1, G-Sync compatible, FreeSync Premium) makes it superior for PS5 and Xbox Series X gaming. Samsung Q80D is a capable gaming TV but the OLED's lower input lag is measurably better.
What is the best 65-inch TV under £1,000 in the UK?
The Samsung Q80D regularly drops to £999 during UK sales events (Black Friday, Amazon Prime Day). Alternatively, the Hisense U7 QLED 65-inch offers excellent value at £699–£799, though it lacks the build quality and smart platform refinement of Samsung or LG.
