What Customers Say
Owners of the 2026 C6 range praise the picture first: vivid, natural colour, deep blacks and detail that several describe as the best they have seen on a television, with the 165Hz gaming performance, easy set-up and a comprehensive app selection close behind. Sound is described as clear and better than expected by most, and owners moving from older LG or Samsung sets say the step up in clarity is obvious. Reviews cover the whole C6 range, since owner reviews are pooled across the 42-inch to 83-inch models; the 77-inch shares the processor, panel technology and connections with the sizes reviewed.
The one repeated complaint is the Magic Remote, whose on-screen pointer several owners find hard to control and impossible to switch off permanently, and one or two have hit software snags such as a juddering Netflix app or a paid membership prompt for the screen-saver gallery.
For a buyer wanting a large OLED for films and console gaming without paying the G6 premium, the 77-inch C6 is the size at which its picture quality makes the most of itself; anyone who wants a simpler remote should budget for a universal one.
Who Should Buy This
- Film fans wanting a big-screen OLED with Dolby Vision, HDR10 and HLG
- Gamers wanting 165Hz VRR with G-Sync and FreeSync on all four HDMI ports
- Home-cinema builders wanting a 77-inch OLED with eARC for a soundbar
- Multi-device households wanting four full-bandwidth HDMI 2.1 inputs
- Sports viewers wanting a sub-0.1 ms response time for fast motion
Who Should Skip It
- Buyers who want the flush gallery mount and higher brightness of the G6
- Anyone wanting more than a 2.2-channel built-in speaker system
- Buyers who dislike a pointer-driven remote control
- Rooms that cannot take a 1.7-metre-wide, 23.5 kg screen
What Experts Says
Overall Assessment and Positioning
The LG OLED77C66LB is the 77-inch model of LG's 2026 C6 OLED evo, the mid-range OLED that sits beneath the gallery-design G6 and carries the same Alpha 11 AI Processor 4K Gen3 and webOS 26. It is the C6 at the size where a living room becomes a home cinema, and LG quotes a 3.2 times peak-brightness gain for the range over a conventional OLED.
Key Strengths and Standout Features
The 4K OLED panel, which LG describes as an anti-glare matte display, runs at a native 120 Hz with variable refresh up to 165 Hz, plays Dolby Vision, HDR10 and HLG, and has a stated response time under 0.1 ms. All four HDMI inputs carry 4K at 120 Hz with eARC, VRR, ALLM, QMS and QFT, and the gaming list adds FreeSync, G-Sync compatibility, HGiG, Dolby Vision gaming and the Game Optimiser dashboard. Sound is a 40 W 2.2-channel system with Dolby Atmos and AI Sound Pro virtual up-mixing, connectivity runs to Wi-Fi 6E, Bluetooth 5.3, Ethernet and two USB ports, and webOS 26 carries AirPlay, Google Cast, hands-free voice control and the LG ThinQ app. A DVB-T2, DVB-C and DVB-S2 tuner with a CI+ slot covers UK broadcast viewing.
Value Proposition and Who It's Best Suited For
At 77 inches this is a 1,711 mm wide, 23.5 kg screen on a 300 x 200 mm bracket, with a stated energy class of E in SDR at 92.7 W and G in HDR at 260 W, so it needs a wall or a wide unit and a room to match. The honest qualifications are the ones shared across the range: the 2.2-channel speakers will not match the picture for a home-cinema buyer, and LG quotes a higher brightness gain and its Reflection Free Premium screen for the G6 above it. For a film watcher or console gamer who wants a large OLED with the full 2026 processor and every HDMI 2.1 feature, the 77-inch C6 is the strongest value in LG's line at this size.
