What Customers Say

Reviewers are impressed by how much brighter and more colour-accurate the C6's picture looks next to its predecessor, crediting the newer processor for richer colour and deeper, more natural shadow detail in dark scenes. Testers rate its black levels, contrast and viewing angles as ahead of most Mini-LED sets and several rival OLEDs in this price bracket. Gaming is a particular strength: HDMI 2.1 bandwidth across all four ports and a high native refresh rate make it a strong option for both console and PC gaming. The smart platform is well stocked with streaming apps and runs smoothly, and the 65-inch size is widely seen as the sweet spot of LG's current OLED range.

The main criticism is reflection handling: unlike LG's more expensive flagship, this panel has no anti-glare coating, so it throws back noticeable, mirror-like reflections in a bright room. Sound is also considered underwhelming for the picture on offer, with a narrow soundstage and limited bass that most reviewers say is worth pairing with a soundbar.

The overall verdict is strongly positive: this is widely regarded as one of the best mid-range OLEDs available, a clear step up for both film and gaming use, provided buyers can control room lighting or add a soundbar.

Who Should Buy This

  • Film fans wanting true OLED blacks with Dolby Vision and HDR10
  • Gamers wanting up to 165Hz with FreeSync and G-Sync compatibility
  • Buyers wanting a near-instant response time for fast motion
  • Multi-device households wanting four HDMI 2.1 ports with eARC
  • Anyone wanting Dolby Atmos sound built into a 2.2-channel system

Who Should Skip It

  • Bright, sunlit rooms where a glossy screen picks up reflections
  • Buyers who specifically want LG's anti-glare G6 flagship instead
  • Anyone wanting more than a 2.2-channel built-in speaker system

What Experts Says

Picture and processing

The OLED65C66LB pairs LG's 2026 OLED evo panel with the Alpha 11 AI Processor 4K Gen3, and the spec sheet backs up reviewers' praise for its colour and brightness gains over the outgoing C5. Dolby Vision, HDR10 and HLG are all supported, and the stated response time of under 0.1ms should keep fast motion free of smearing, whether that's sport, action films or competitive gaming.

Gaming and connectivity

Four HDMI 2.1 ports support 4K at up to 120Hz with eARC, VRR, ALLM, QMS and QFT, and LG states compatibility with both AMD FreeSync and Nvidia G-Sync alongside native refresh rates up to 165Hz, a genuinely strong spread of gaming features for a mid-range OLED rather than a flagship. Wi-Fi 6E and Bluetooth 5.3 round out the wireless connectivity, and webOS 26 adds Google Gemini and Microsoft Copilot integration on top of the usual streaming apps.

Sound and everyday use

A 2.2-channel, 40W speaker system with Dolby Atmos handles built-in audio, which should suit casual viewing without stretching to a soundbar for most rooms. webOS 26 runs the smart platform, with LG's ThinQ app offering remote control from a phone. As with most glossy OLED panels, expect some reflections in a bright room; buyers who specifically want to minimise that should look at LG's step-up G6 with its anti-glare coating instead.
