Overview
The LG SM8600PUA 65-inch NanoCell 4K Smart TV sits in the upper-mid tier of LG’s 2019 lineup, offering a genuine step up from entry-level 4K sets without crossing into OLED territory. NanoCell technology works by filtering impure wavelengths at the pixel level, delivering more accurate, saturated colors and a wide viewing angle that holds up across a large room. The α7 Gen 2 processor handles upscaling and picture optimization ably, though it sits one step below LG’s flagship α9 chip. Full Array Dimming improves local contrast, but don’t expect inky blacks here. Think of this as a capable, well-rounded set — not a dedicated dark-room performer.
Features & Benefits
The IPS NanoCell panel is the headline feature — sit off to the side in a wide living room and the picture barely shifts, something VA-based sets simply can’t match. The 120Hz refresh rate keeps fast action clean, making sports and motion-heavy content look sharp without obvious judder. HDR coverage spans Dolby Vision, HDR10, and HLG, so virtually every streaming platform and Blu-ray disc is covered. The built-in ThinQ AI platform runs Netflix, Disney+, and other major apps without an external stick. Forty watts of Dolby Atmos audio won’t blow anyone away, but it’s a solid starting point before adding a soundbar. Four HDMI ports handle multiple devices without juggling cables.
Best For
This 65-inch LG makes the most sense for larger shared living spaces — think a room where people spread across sofas at different angles, because the IPS panel keeps color and brightness consistent no matter where you’re seated. Sports fans will appreciate the motion clarity and steady color rendering during fast-moving broadcasts. Cord-cutters will find webOS genuinely easy to navigate day-to-day, with voice control via Alexa or Google Assistant covering most routine commands. Casual gamers get a large, HDR-capable screen with reasonable response. If deep black levels for late-night movies in a darkened room are your priority, an OLED or VA-panel set would serve you better.
User Feedback
Owners of the SM8600PUA consistently praise the out-of-box picture quality — colors impress right away without extensive calibration, and most buyers find the Magic Remote intuitive from the start. The webOS interface draws frequent compliments for being responsive and uncluttered. On the critical side, viewers who watch dark or night-heavy content regularly flag light blooming around bright objects on black backgrounds, an inherent IPS trait no firmware update fully resolves. A handful of buyers have raised questions about how long LG will push app and software updates to a 2019 model. Built-in sound divides opinion: perfectly adequate for casual viewing, but underwhelming for anyone serious about audio quality.
Pros
- Wide IPS viewing angles keep picture quality consistent for large groups spread across the room.
- NanoCell filtering produces noticeably more accurate, vibrant colors than standard LED panels.
- 120Hz refresh rate handles sports and action content cleanly without obvious motion blur.
- Full Dolby Vision, HDR10, and HLG support covers every major HDR format across streaming and disc.
- webOS is one of the more intuitive smart TV platforms — fast, clean, and easy to pick up.
- The Magic Remote pointer-style navigation makes browsing apps and menus much less frustrating than a standard d-pad remote.
- Built-in Google Assistant and Alexa work reliably for everyday voice commands and smart home control.
- Four HDMI ports comfortably accommodate a console, soundbar, streaming stick, and Blu-ray player simultaneously.
- Out-of-box picture calibration is strong enough that most buyers won’t need to touch advanced settings.
- At 65 inches, this LG NanoCell TV delivers a genuinely cinematic screen size without pushing into premium price territory.
Cons
- IPS black levels are mediocre — dark scenes show visible light bloom that VA and OLED panels handle far better.
- Full Array Dimming implementation is modest; local contrast improvement is real but limited compared to higher-end zone systems.
- Built-in 40W audio starts to strain at higher volumes and lacks the bass presence a room this size deserves.
- As a 2019 model, long-term app support and OS updates are not guaranteed beyond a few years.
- The α7 Gen 2 processor handles most tasks well but can feel sluggish when multitasking across multiple apps.
- Bright room performance is decent but not exceptional — high-glare environments can wash out darker image areas.
- The stand footprint is wide, requiring a TV console at least 55 inches across to sit safely without wall-mounting.
- HDR peak brightness, while adequate, falls short of what high-end LED TVs deliver for truly punchy HDR highlights.

Suitable for:
The LG SM8600PUA 65-inch NanoCell 4K Smart TV is purpose-built for households where the TV is a shared, central fixture rather than a personal screen. Families with a wide living room will immediately notice the IPS panel's consistency — colors and brightness hold steady whether you're sitting directly in front or at a sharp angle from the side, which is rare at this display tier. Sports fans in particular get a lot of value here: the 120Hz refresh rate keeps fast motion crisp, and the color accuracy means jerseys and stadium greens look true-to-life rather than oversaturated. Cord-cutters will find the webOS platform genuinely practical for day-to-day streaming, with Dolby Vision support covering everything from Netflix 4K to HDR Blu-ray. Casual gamers who want a large, HDR-capable screen without spending significantly more will also find this a comfortable fit.
Not suitable for:
Buyers with a dedicated dark home theater room should think carefully before committing to the LG SM8600PUA 65-inch NanoCell 4K Smart TV. The IPS panel, while excellent for wide viewing angles, cannot compete with OLED or even a good VA-panel LCD when it comes to black levels — light blooming around bright objects against dark backgrounds is a real and recurring complaint, not an edge case. If you primarily watch atmospheric films, dark TV dramas, or horror content in a light-controlled room, the contrast limitations will be noticeable and persistent. Audiophiles or anyone who takes sound seriously should also budget for a soundbar from day one, as the built-in speakers are adequate but not a long-term solution at this screen size. Finally, buyers who demand the latest app ecosystem and guaranteed long-term software updates should note this is a 2019 model, and platform support for older sets has limits.
Specifications
