Hisense 100U8QG 100" VS LG 100QNED85AU 100"

Both TVs share a strong common foundation: identical 4K (3840 x 2160) resolution at 44 ppi, 10-bit color depth rendering 1.07 billion colors, and symmetrical 178° viewing angles in both axes — meaning neither has an edge in raw sharpness or color volume at the panel level. Both also include anti-reflection coating and an ambient light sensor, useful for automatic brightness adjustment in varying room conditions.

The meaningful differences emerge in panel technology, HDR ecosystem support, and motion handling. The Hisense 100U8QG uses a QLED Mini-LED panel, adding a Quantum Dot layer on top of the Mini-LED backlight for wider color gamut coverage — a combination the LG lacks, as the 100QNED85AU relies on a standard Mini-LED LCD without Quantum Dot enhancement. On HDR, the Hisense supports HDR10, HDR10+, Dolby Vision, and HLG — covering every major format — while the LG drops both HDR10+ and Dolby Vision, leaving it with only HDR10 and HLG. In practice, this means a significant portion of HDR-mastered streaming content (Netflix Dolby Vision, Amazon HDR10+) will not be tone-mapped to its full intended quality on the LG.

For gaming, the Hisense also pulls ahead with a 165Hz refresh rate versus the LG's 144Hz, and supports AMD FreeSync Premium Pro — the highest FreeSync tier, which adds Low Framerate Compensation and HDR requirements — compared to the LG's AMD FreeSync Premium. Overall, the Hisense 100U8QG holds a clear display advantage in this group, offering a more capable panel technology, broader HDR format coverage, and superior gaming-oriented refresh and sync specifications.

Connectivity is largely a tie between these two TVs, with both offering HDMI 2.1, Wi-Fi 6E, Bluetooth 5.3, dual USB ports, a wired Ethernet port, and Miracast support. HDMI 2.1 is particularly relevant at this screen size, as it enables 4K@120Hz passthrough from current-gen consoles and high-end graphics cards without bandwidth limitations. Wi-Fi 6E extends into the 6GHz band, reducing congestion in dense wireless environments and ensuring stable streaming even in busy households.

Two differences are worth noting. The LG 100QNED85AU provides 4 HDMI ports versus the Hisense's 3 — a practical advantage for users running multiple simultaneous sources such as a console, a soundbar via ARC, a streaming stick, and a Blu-ray player, eliminating the need for an HDMI switch. On the other side, the Hisense 100U8QG includes a 3.5mm audio jack, which the LG omits entirely. While often overlooked, this port offers a direct and latency-free connection for headphones or legacy audio equipment without requiring Bluetooth pairing.

On balance, the edge in this group leans slightly toward the LG 100QNED85AU for most home theater setups. An extra HDMI 2.1 port is a tangible, everyday convenience that affects how the TV integrates into a full AV ecosystem, while the 3.5mm jack on the Hisense, though useful in specific scenarios, is a narrower advantage. Users who prioritize headphone connectivity or have fewer HDMI devices may find the two essentially equivalent in practice.

For the most part, these two TVs are evenly matched on audio. Both carry stereo speakers with a built-in subwoofer, support the full Dolby suite — Dolby Digital, Dolby Digital Plus, Dolby Atmos, and Dolby Audio — and offer both HDMI ARC and eARC for external audio system integration. eARC is the more significant of those two, as it provides enough bandwidth to pass lossless audio formats like Dolby TrueHD and uncompressed multichannel PCM to a compatible soundbar or AV receiver, making it essential for users who want to extract the highest quality audio from Blu-ray or high-end streaming sources.

The one differentiator in this group is DTS:X, which the Hisense 100U8QG supports and the LG does not. DTS:X is an object-based surround format — the DTS counterpart to Dolby Atmos — found on a significant portion of 4K Blu-ray discs and some streaming content. Without it, the LG would decode DTS:X tracks as standard DTS or may not process them optimally, potentially missing the spatial audio layer the content was mastered with. For users who rely heavily on physical media or DTS-encoded content, this gap is real.

That said, Dolby Atmos has considerably broader adoption across streaming platforms and modern discs, so the practical impact depends on the user's content mix. Still, based strictly on the provided specs, the Hisense 100U8QG holds a narrow edge in audio format coverage — covering both major object-based surround ecosystems where the LG covers only one.

At 100 inches, both TVs share an identical footprint in width and are within 5mm of each other in height — so neither will fit where the other won't. The meaningful physical differences come down to depth and weight. The LG 100QNED85AU measures just 50.8mm thick compared to the Hisense's 81.3mm, a 37% reduction that translates directly into a slimmer wall profile and a more contemporary aesthetic when mounted. This also drives a dramatic difference in overall volume: the LG displaces roughly 144,738 cm³ versus the Hisense's 232,563 cm³ — nearly 38% less bulk.

Weight cuts the other way. The Hisense 100U8QG comes in at approximately 63.5 kg, while the LG is notably heavier at around 68.1 kg — a difference of roughly 4.5 kg. At this scale, both TVs require multiple people and potentially professional installation regardless, so the weight gap is unlikely to be decisive. However, the lighter Hisense could be marginally easier to maneuver during positioning. Both units support VESA mounting, so wall installation is an option for either.

Overall, the LG 100QNED85AU holds the design edge for users where aesthetics and wall-mounted sleekness are priorities — its significantly slimmer profile makes a real visual difference on the wall. The Hisense is the lighter option, but the LG's reduced depth and volume are more impactful design advantages for the majority of installations.

Across the features category, these two TVs are remarkably alike. Both run a built-in smart TV platform, support AirPlay, voice commands via Google Assistant and Alexa, smartphone remote control, USB recording, and identical standby power consumption of 0.5W. Neither supports Apple HomeKit/Siri integration, and neither ships with a rechargeable remote. For the vast majority of users, the day-to-day smart feature experience will be functionally indistinguishable between the two.

The only differentiator in this group is the warranty period. The Hisense 100U8QG includes a 2-year warranty, while the LG 100QNED85AU offers just 1 year. On a flagship-sized, high-investment TV, this gap carries real financial weight — an extended manufacturer warranty means an additional year of covered repairs or replacement without out-of-pocket costs, which is particularly meaningful for a panel of this size where servicing is neither cheap nor straightforward.

Given how closely matched everything else is, the Hisense 100U8QG holds a clear edge in this group purely on the strength of its longer warranty. It represents tangible added value and reduced ownership risk that the LG simply does not match on paper.
