LG 100QNED85AU 100" VS Samsung QN85Q8FAAF 85"

Both the LG 100QNED85AU and the Samsung QN85Q8FAAF share a strong display foundation: native 4K (3840 x 2160) resolution, 10-bit color depth capable of rendering 1.07 billion colors, a 144Hz refresh rate, and AMD FreeSync Premium adaptive sync — making both equally capable for smooth motion and gaming. Anti-reflection coatings and ambient light sensors are present on both, and their viewing angles are identical at 178° horizontal and vertical, so neither has an edge in off-axis performance.

The most meaningful differentiator is panel technology. The LG uses a Mini-LED backlight over an LCD panel, which delivers more precise local dimming zones and generally stronger contrast and brightness control compared to conventional LED-LCD. The Samsung relies on QLED (quantum dot LCD), which excels in color volume and peak brightness but lacks the granular backlight control of Mini-LED. In practice, the LG's Mini-LED architecture should produce more nuanced HDR rendering, while the Samsung's QLED layer gives it an advantage in saturated, vivid color output. The Samsung also supports HDR10+ — the dynamic metadata HDR format — while the LG does not, meaning compatible HDR10+ content will be tone-mapped more accurately scene-by-scene on the Samsung. Neither supports Dolby Vision, so that is a non-factor.

On sheer size, the LG's 100.3″ screen is in a different class than the Samsung's 84.5″, but this comes at a cost: its pixel density drops to 44 ppi versus the Samsung's 52 ppi. At typical living-room viewing distances this gap is unlikely to be perceptible, but up close the Samsung will appear slightly sharper. Overall, the Samsung QN85Q8FAAF holds a technical edge in display quality thanks to HDR10+ support and higher pixel density, while the LG 100QNED85AU counters with its Mini-LED precision and a dramatically larger canvas — making the better choice highly dependent on room size and viewing priorities.

For the most part, connectivity is a dead heat between these two TVs. Both offer 4 HDMI 2.1 ports — critical for next-gen console and PC gaming at high refresh rates — along with 2 USB ports, a dedicated RJ45 ethernet port, Miracast screen mirroring, and Bluetooth 5.3. The shared Bluetooth version ensures stable, low-latency connections with modern peripherals like soundbars and headphones, and neither model is at a disadvantage here.

Where the two diverge is wireless networking. The LG 100QNED85AU supports Wi-Fi 6E in addition to Wi-Fi 6, 5, and 4, while the Samsung QN85Q8FAAF tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6E operates on the 6 GHz band, which is less congested than the 2.4 GHz and 5 GHz bands used by older standards. In a busy household with many connected devices, this translates to more consistent streaming throughput, lower latency, and reduced interference — advantages that become especially noticeable when streaming 4K HDR content or using cloud gaming services.

The LG holds a clear edge in this group purely on the strength of its superior wireless capability. For users who rely on ethernet, the gap is irrelevant — both are equally well-equipped. But for anyone streaming over Wi-Fi, particularly in a congested network environment, the LG's Wi-Fi 6E support is a meaningful, future-proof advantage that the Samsung simply cannot match.

Audio formats tell a consistent story across both TVs: Dolby Atmos, Dolby Digital Plus, Dolby Audio, Digital Out, stereo speakers, and HDMI ARC/eARC are all present on both the LG 100QNED85AU and the Samsung QN85Q8FAAF. The shared eARC support is worth noting — it allows lossless, high-bandwidth audio passthrough to a compatible soundbar or AV receiver, making either TV a solid foundation for a high-end external audio setup.

The single differentiator in this group is the LG's inclusion of a built-in subwoofer, which the Samsung lacks. A dedicated subwoofer handles low-frequency reproduction — the deep rumble of explosions, the weight of a film score's bass notes — that standard TV speakers, however well-tuned, struggle to convey. For viewers who plan to use the TV's internal speakers without an external audio system, this is a tangible, everyday advantage.

The LG 100QNED85AU takes a clear edge in this group. Its built-in subwoofer gives it a more complete standalone audio experience out of the box. The Samsung is not at a disadvantage for users who intend to pair it with a soundbar or AV receiver, but for those relying solely on the TV's own speakers, the LG's low-end reinforcement is a meaningful practical benefit.

The physical scale difference between these two TVs is substantial and deserves careful consideration before purchase. The LG 100QNED85AU measures 2230 mm wide and weighs 68 kg, while the Samsung QN85Q8FAAF comes in at 1900 mm wide and just 41 kg. That 27 kg weight gap is not trivial — it has direct implications for wall-mount hardware ratings, the number of people needed for installation, and whether certain furniture or wall structures can support the set safely.

Thickness is another area where the Samsung distinguishes itself. At 27.9 mm slim versus the LG's 50.8 mm, the Samsung sits considerably flatter against a wall, lending itself more naturally to a clean, low-profile wall installation. The LG's greater depth — partly a consequence of its Mini-LED backlight assembly — makes it bulkier in profile, which may be more noticeable in smaller or design-conscious spaces. Both support VESA mounting, so neither is locked out of wall installation, but the Samsung will simply look sleeker once mounted.

Predictably, the LG's volume — at roughly 144,738 cm³ compared to the Samsung's 57,624 cm³ — reflects just how much more physical presence a 100″ screen commands versus an 85″ one. Neither TV has a design advantage in the traditional sense; the differences here are driven entirely by screen size. The Samsung QN85Q8FAAF is meaningfully easier to handle, install, and accommodate in a wider range of room sizes, while the LG is the right choice only when the space — and the wall — can genuinely support it.

Feature parity between these two TVs is remarkably high. Both carry built-in smart TV platforms, AirPlay, Google Assistant, Alexa voice control, smartphone remote support, USB recording, and a matched 0.5W standby power consumption. Neither supports Siri or Apple HomeKit, and both carry identical 1-year warranty coverage. For the vast majority of everyday smart TV use cases, buyers will find no practical difference between the two.

Dig into the details, and one minor but recurring convenience stands out: the Samsung QN85Q8FAAF includes a rechargeable remote control, while the LG does not. It is a small thing in isolation, but over years of ownership the elimination of disposable batteries — and the frustration of a dead remote at an inconvenient moment — adds up. It reflects a polish in the out-of-box experience that some users will appreciate.

The Samsung takes a narrow edge in this group on the strength of its rechargeable remote, which is the only differentiator the data supports. It is not a decisive factor for most buyers, but in an otherwise dead-even feature set, it is the sole detail that tips the scales.
