TECH REVIEW – The LG OLED evo AI G6 is the kind of television that makes it immediately obvious how far OLED technology has progressed in just a few years. Perfect blacks and pixel-level contrast have long been part of the formula, but the G6 adds exceptionally powerful HDR brightness, an Alpha 11 Gen 3 processor, 4K/165Hz gaming support and significantly improved reflection handling. The OLED55G61LW is expensive, and webOS was not completely trouble-free during my time with it, but for picture quality, movies and gaming alike, this is one of the finest TVs you can currently put in a living room.

LG’s G series has long represented the top of the company’s conventional OLED range, and that remains true in 2026. The 55-inch model I tested is the LG OLED evo AI G6 OLED55G61LW, the 139cm version sold on the Hungarian market. Behind its 3840 x 2160 panel sits LG’s new third-generation Alpha 11 4K AI processor, while webOS 26, Dolby Vision, Dolby Atmos and comprehensive HDMI 2.1 connectivity ensure that the specification sheet is every bit as premium as the picture.

The 2026 G6 is not a generational revolution that completely reinvents LG’s OLED concept. Instead, it is a refinement of the already excellent G5, but several of the improvements are immediately visible in everyday use. Brightness, dark-tone handling, gradients, reflections and image processing have all moved forward, making the G6 feel less like a routine specification update and more like an extremely mature flagship television.

Design: A True Gallery TV Built for the Wall

LG has not attempted to redesign the exterior simply for the sake of change, and I think that was the right decision. The G6 remains an exceptionally slim, understated television with an almost completely flat rear panel that makes its Gallery-series positioning obvious when wall-mounted. The OLED55G61LW chassis is only 27.2mm deep, measures 1222 x 703mm without a stand and weighs 16.8kg.

The LW variant is primarily configured for wall installation, with connectors facing sideways or downward so that cables do not interfere with flush mounting. The rear is functional rather than decorative, but everything feels neat and carefully considered. Thin bezels, subtle silver detailing and that enormous black OLED surface combine to deliver exactly the premium appearance expected at this price.

Key Specifications

Display: 55-inch 3840 x 2160 4K OLED evo panel with a native 120Hz refresh rate and VRR up to 165Hz with a PC. Processor: Alpha 11 Gen 3 4K AI Processor. HDR: Dolby Vision, HDR10 and HLG. Gaming: VRR up to 165Hz, NVIDIA G-SYNC Compatible, AMD FreeSync Premium, ALLM, HGiG, Dolby Vision Gaming and Game Optimizer. Connectivity: four HDMI 2.1 ports, three USB 2.0 ports, eARC, Ethernet, optical audio, Wi-Fi 6E and Bluetooth 5.3. Audio: 4.2-channel 60W system with Dolby Atmos. Operating system: webOS 26.

LG has not played the familiar flagship-TV trick of making only one or two HDMI sockets fully capable. All four handle 4K/120Hz, VRR, ALLM, QMS and QFT, while HDMI 2 also provides eARC functionality. With a compatible PC, variable refresh extends all the way to 165Hz, which remains a serious gaming specification even for a 2026 flagship television.

Picture Quality: This Is Why Flagship OLED Exists

The G6’s defining feature is naturally its picture, and there is very little to criticize here. OLED’s pixel-level light control means blacks are genuinely black, there is no blooming and no halo from a backlight surrounding bright objects, while stars and tiny highlights remain precisely defined against dark backgrounds. Viewing angles are also excellent, with contrast and color holding up remarkably well from the side.

The major development, however, is brightness. Independent measurements in Filmmaker Mode put the G6 at 2481 nits on a 10% HDR window and slightly above 3100 nits for very small 1-2% highlights. Even more importantly, full-screen white reaches approximately 471 nits, meaning automatic brightness limiting is less aggressive than on earlier generations.

That matters much more in practice than the headline numbers themselves. Sunlight, neon signs, explosions and specular reflections in HDR movies genuinely leap away from the image while the surrounding darkness remains perfectly black. Bright daytime scenes also retain substantially more energy than they did on older OLED televisions.

Color reproduction is similarly excellent. Independent testing recorded almost complete DCI-P3 coverage and roughly 78% Rec.2020, which is an impressive result. Filmmaker Mode already produces a natural and well-balanced image from the factory, so it would be my starting point for movies rather than the more spectacular but less accurate Vivid or Standard modes.

Alpha 11 Gen 3: Processing That Genuinely Matters

The G6’s Alpha 11 Gen 3 processor brings more than another collection of AI labels. Its 12-bit processing pipeline, combined with still finer internal luminance calculations, noticeably improves gradients and handling of very dark tones. One of the characteristic weaknesses of previous WOLED panels, visible banding in near-black transitions, is substantially less intrusive.

It is not completely gone. Extremely dark, heavily compressed sources can still produce some banding or flickering tonal noise, some of which originates in the content itself. The lowest Smooth Gradation setting can help in those situations, although with good 4K streaming or UHD Blu-ray material it is usually unnecessary.

Upscaling is also strong, particularly with good-quality 1080p sources. LG’s Super Resolution algorithm works on texture as well as edges, although with low-bitrate or DVD-quality sources it can become too aggressive and expose compression artifacts. Feed it a strong source, however, and the G6 looks exceptionally clean and natural.

Movies: One of the Best Arguments for OLED

Movies are where the G6’s abilities become especially obvious. Dolby Vision, perfect blacks and extreme local contrast create a sense of depth that even very capable Mini LED televisions struggle to reproduce consistently. Dark science-fiction scenes can display tiny stars with pixel-level precision, while bright HDR sequences no longer suffer from the feeling that an OLED panel is holding itself back.

Reflection handling has also improved considerably. The Reflection Free Premium certified coating suppresses distracting ambient reflections very effectively, making the G6 much more practical in a bright living room than older glossy OLED displays. Crucially, blacks do not take on the gray appearance associated with some heavily matte anti-glare treatments, so the display retains OLED’s characteristic depth.

Dolby Vision is present, of course, while HDR10+ remains absent. Dolby Vision’s broad adoption makes this less serious than it might otherwise be, but it is still a conspicuous omission on a flagship television. For movie collectors, the lack of DTS support is more irritating, especially for anyone with a substantial Blu-ray or UHD Blu-ray library.

Gaming: Almost a Dream TV for PS5 Pro and PC

On paper, the G6 checks almost every important gaming box. Four HDMI 2.1 inputs, VRR, ALLM, HGiG, G-SYNC Compatible and FreeSync Premium support, plus 165Hz operation with a 4K PC signal, place it firmly among the most capable gaming televisions available. Pixel response is effectively instantaneous, with LG officially quoting response times below 0.1ms.

Independent input-lag testing recorded 10.8ms at 4K/60Hz in Game mode, with even lower latency available at higher refresh rates. In actual play, it feels exactly as it should: immediate, clean and responsive. There is no LCD-style motion smearing, while OLED blacks and the G6’s powerful HDR performance can make visually ambitious games look spectacular.

I did encounter one frustrating software issue with my PlayStation 5 Pro. Even after the television had been in use for an extended period, it did not always find or correctly identify the PS5 Pro, and ordinary cable, HDMI-port and input checks did not provide a lasting solution. Ultimately, I had to restore webOS to its factory state before device detection returned to normal.

That is frustrating because once the console and television communicate correctly, the G6 is a superb PS5 Pro display. 4K HDR, VRR, ALLM and the responsiveness of OLED create a combination that is difficult to leave behind once you have experienced it. The issue therefore does not undermine the quality of the gaming experience itself, but device detection on a flagship television at this price should simply work reliably every time.

webOS 26: Fast, Versatile, Occasionally Overcomplicated

webOS 26 remains one of the better smart-TV platforms overall. The major streaming applications are available, alongside Google Cast, Apple AirPlay, ThinQ integration, Home Hub and Matter support, while LG promises five years of operating-system upgrades through its Re:New program. The home screen and Quick Cards can also be customized extensively.

AI functionality now includes Google Gemini and Microsoft Copilot integration, but to me these remain supplementary features rather than reasons to buy a television. AI Concierge, AI Chatbot and the picture and sound wizards can be interesting, but what really matters is that apps launch quickly, HDMI sources remain stable and menus stay out of the user’s way. webOS usually handles those basics well, although the PS5 Pro incident demonstrates that the software layer is not completely bulletproof.

I am also not especially fond of webOS continuing to reserve prominent space for recommendations and advertising-style content. Much of it can fortunately be disabled, and doing so is worthwhile. Once cleaned up, the interface is significantly more pleasant.

Sound: Surprisingly Capable, but This Picture Deserves More

The built-in 4.2-channel system delivers 60W and sounds impressively substantial considering how thin the television is. Dolby Atmos, AI Sound Pro, Clear Voice Pro and virtual 11.1.2-channel processing are available. Dialogue, regular television and casual movie viewing are handled well.

Bass obviously cannot reproduce what a proper separate subwoofer can do, and virtual surround cannot replace physical rear speakers. With picture quality this good, I would still pair the G6 with a capable soundbar or dedicated home-theater system. The absence of DTS is again worth keeping in mind for owners of larger physical movie collections.

About HUF 800,000: An Extremely Premium TV at an Extremely Premium Price

At the time of writing, the 55-inch OLED55G61LW sells for around HUF 799,990 at major Hungarian retailers, with a few offers sitting marginally below that figure. That is a great deal of money for a 55-inch television, even when the product in question is one of the best OLED models on the market. Price-to-performance therefore cannot receive the same score as pure picture quality.

The G6 does, however, deliver genuinely high-end technology for the money. Exceptional HDR brightness, perfect blacks, excellent reflection handling, four full HDMI 2.1 inputs, 165Hz PC VRR and five years of webOS upgrades make for a package very few competitors can match simultaneously. I would not call it a bargain in the conventional sense, but buyers shopping at the top of the picture-quality market can clearly see where the premium goes.

Verdict: One of the Best OLED TVs You Can Buy Today

The LG OLED evo AI G6 is not a revolution but an exceptionally convincing mature version of technology that was already excellent. Picture quality is superb: blacks are perfect, HDR brightness is extreme by OLED standards, colors are accurate, gradients are improved and reflections are far less distracting. For films, television and gaming alike, it reaches a level where finding serious picture-quality weaknesses becomes genuinely difficult.

webOS could be less advertising-heavy, the lack of DTS and HDR10+ remains strange on a flagship product, and the PS5 Pro detection problem is difficult to excuse on a television costing close to HUF 800,000. Restoring webOS to its factory state ultimately solved that issue, after which the console experience was exactly as impressive as the hardware suggested it should be. Those weaknesses do not change the overall verdict: the G6 is currently one of the strongest all-round OLED televisions for movie enthusiasts and gamers alike.
