LG G6 OLED Review: The Bright-Room OLED Finally Arrives

The LG G6 is the top of LG's mainstream OLED range for 2026, sitting alongside the new Wallpaper-style W6 and above the C6 and B6. In the US it launched in March 2026 in 55, 65, 77 and 83-inch sizes, with a 97-inch version that uses an older panel and behaves differently, and a 48-inch version sold outside North America. It is flagship money, priced roughly in line with what the G5 launched at. The gallery design means it is built to be wall-mounted flush, though 55 and 65-inch buyers can get a pedestal stand. It is aimed at people who want cinema-grade blacks in a living room with actual windows.

The LG G6 spec sheet, verified across LG's own materials and published reviews:

• Second-generation Four Stack Primary RGB Tandem OLED panel on 55, 65, 77 and 83-inch models
• Alpha 11 AI Processor Gen 3 with 12-bit color processing and 13-bit output
• Brightness Booster Ultimate, Dual AI Super Resolution and Dynamic Tone Mapping Ultra
• Four HDMI 2.1 ports, all supporting 4K at up to 165Hz
• VRR with both AMD FreeSync and Nvidia G-Sync certification, HGiG, auto low latency mode, Dolby Vision gaming
• Dolby Vision, HDR10 and HLG; no HDR10+ and no Dolby Vision 2
• Dolby Atmos over a 4.2-channel, 60W speaker array; no DTS decoding on board
• webOS 26 with expanded Quick Cards, a customizable Quick Menu and a generative AI concierge
• Dolby Atmos FlexConnect support, Apple AirPlay 2 and Chromecast built in

LG promised a 20 percent brightness increase and a new Hyper Radiant Color system. Independent measurements went further: reviewers recorded around 2,471 nits of peak HDR brightness in Filmmaker Mode and about 2,454 in Standard, against roughly 1,850 nits from the G5 in the same Standard measurement. Full-screen HDR brightness climbed from about 331 nits to 455 in Filmmaker Mode, which is the figure you actually notice on daytime sport. The Alpha 11 Gen 3 chip brings 12-bit processing and better upscaling. Input lag dropped to a measured 8.9ms. Sound modes were cut from eight to four, and LG retuned the AI Sound Pro profile to be bassier and more mid-focused.

Reflection handling is the headline. Multiple reviews describe the LG G6 as holding its picture together with overhead lights on in a way previous OLEDs could not, and doing it while keeping blacks genuinely black — where a matte anti-glare screen kills mirror reflections but can leave dark tones looking gray. Color is the other strength: measured gamut coverage of 99.3 percent of DCI-P3 and 82.7 percent of BT.2020, with out-of-box accuracy good enough that most people never need to touch a setting. Gaming is close to untouchable, with four full-bandwidth HDMI 2.1 ports and every current feature supported. webOS 26 remains one of the better smart platforms.

LG has confirmed no plans to support Dolby Vision 2 on its 2026 sets, while Philips, TCL and Hisense have committed to it — a small point today, since no content uses it yet, but an awkward one on a TV people keep for years. HDR10+ is still absent, as ever. The built-in 4.2-channel sound is competent and accurate but stays contained within the screen's width; anything with this picture deserves a soundbar. Early software had accuracy problems that prompted a round of updates. And the 97-inch model uses a different, older panel, so do not assume the review numbers carry over.

Buy the LG G6 if your TV lives in a bright room and you refuse to trade away OLED's black levels to fix it, or if you game on a PC and want 165Hz across four ports. Buy it if you want accurate color with minimal fiddling. Skip it if you are sitting in a dedicated dark room, where the G5 or a 2025 flagship at clearance pricing gets you most of the way for much less. Skip it if HDR10+ or future Dolby Vision 2 support is a dealbreaker. And skip the 97-inch if you are expecting the same panel behavior as the mainstream sizes.

Samsung's S95H is the direct rival, arriving in June 2026 with a matte Glare Free screen that kills reflections more completely, higher measured peak brightness and HDR10+ instead of Dolby Vision. It also introduced a divisive silver FloatLayer frame and dropped the separate One Connect box. LG's own C6 is the value play, using the Alpha 11 Gen 3 chip with a conventional OLED panel at most sizes. For a different flavour entirely, Sony's Bravia 9 II swaps OLED for an RGB Mini LED backlight and chases mastering-monitor accuracy at very high brightness.
