LG 65QNED92AUA 65" VS TCL 98QM6K 98"

Both the LG 65QNED92AUA and the TCL 98QM6K share the same 4K (3840 x 2160) resolution, 10-bit depth, and 1070 million colors, meaning neither has a raw resolution advantage over the other. However, because the LG operates that pixel count across a 65.1″ panel versus the TCL's 97.5″ panel, the LG delivers a noticeably sharper image at 68 ppi compared to the TCL's 45 ppi. In practice, this matters most at close seating distances — the LG will look crisper up close, while the TCL's lower pixel density becomes less perceptible the further back you sit, which is the natural viewing distance for a screen that large.

On motion and HDR, the TCL holds meaningful advantages. Its 144Hz refresh rate edges out the LG's 120Hz, which translates to smoother motion in fast-paced content and gaming. For variable refresh rate gaming specifically, the TCL also supports AMD FreeSync Premium Pro — a tier above the LG's FreeSync Premium — adding low-latency HDR support in VRR mode. On the HDR front, the TCL supports HDR10+ (dynamic metadata), while the LG does not, giving the TCL a broader compatibility range across HDR-mastered content. Both support Dolby Vision and HLG, so this gap only surfaces with HDR10+ encoded material.

For shared traits, both TVs feature Mini-LED backlighting, anti-reflection coatings, ambient light sensors, and identical 178° horizontal and vertical viewing angles, so neither distinguishes itself there. Overall, the TCL 98QM6K has the display edge on paper — higher refresh rate, wider HDR format support, and a more advanced VRR tier — though buyers prioritizing pixel sharpness at a closer seating distance will find the LG's higher pixel density more relevant to their experience.

The wired connectivity picture is identical between the two TVs — both offer four HDMI 2.1 ports, two USB ports, and a single RJ45 ethernet jack, making neither a standout on that front. Where things diverge is wireless. The LG supports Wi-Fi 6E (802.11ax) in addition to Wi-Fi 4, 5, and 6, while the TCL tops out at Wi-Fi 5 (802.11ac). This is a meaningful gap: Wi-Fi 6E operates on the 6 GHz band, which is far less congested than the 2.4 GHz and 5 GHz bands used by older standards, resulting in lower latency and more consistent throughput in dense wireless environments — exactly the conditions found in modern homes with many connected devices.

On Bluetooth, the TCL carries a slight generational edge with version 5.4 versus the LG's 5.3. In practical terms, the difference between these two versions is minor — both offer strong range and stability — so this alone is unlikely to influence a purchase decision. Both TVs also support Miracast for screen mirroring, and neither includes a 3.5mm headphone jack or external memory slot, keeping that aspect of the comparison square.

Taking connectivity as a whole, the LG 65QNED92AUA holds a clear advantage, primarily due to its Wi-Fi 6E support. For users streaming high-bandwidth content or gaming wirelessly in a crowded network environment, the access to the 6 GHz band can make a tangible difference in reliability and latency — something the TCL's Wi-Fi 5 ceiling simply cannot match.

Rarely does a spec group land as a complete dead heat, but audio is exactly that here. Every listed attribute — from Dolby Atmos and Dolby Audio support to the inclusion of a built-in subwoofer, stereo speakers, and both HDMI ARC and eARC — is identical across the LG 65QNED92AUA and the TCL 98QM6K. There is not a single differentiator in the provided data.

The shared highlights are worth noting for context. Dolby Atmos support means both TVs can decode object-based surround sound from compatible streaming services and Blu-ray sources, delivering a more immersive audio experience than standard 5.1 or 7.1 channel formats. Meanwhile, HDMI eARC — the enhanced version of the Audio Return Channel — allows high-bandwidth, lossless audio formats like Dolby TrueHD and DTS:X to pass between the TV and a soundbar or AV receiver over a single HDMI cable, which is a practical advantage for users building out a home theater setup.

With no differentiating data points to separate them, audio is a clear tie. Neither TV holds an advantage over the other based strictly on the provided specs, and buyers should look to other specification groups — or real-world listening tests — to inform their decision in this area.

The physical scale difference between these two TVs is dramatic, and largely expected given the screen size gap. The TCL 98QM6K spans 2180.1 mm wide and stands 1246.9 mm tall, compared to the LG's 1445.3 mm width and 830.6 mm height — making the TCL roughly 50% larger in both dimensions. This has direct room-planning implications: the TCL demands a genuinely large wall or entertainment unit, and buyers should carefully measure their space before committing. The LG, by contrast, fits comfortably in rooms where a 65″ TV is a standard choice.

Weight is where the practical handling difference becomes most striking. The TCL tips the scales at 53,302 g (approximately 117 lbs), nearly three times the LG's 19,006 g (roughly 42 lbs). For installation purposes, the TCL will almost certainly require two people and potentially professional mounting, especially on a wall. The LG's significantly lower mass makes repositioning or single-person installation far more manageable. The TCL is also marginally thicker at 64 mm versus the LG's 58.4 mm, though this distinction is minor in real-world terms.

Both TVs support VESA mounting, so neither restricts the buyer to a specific installation method. That said, design as a whole is not a competition of quality here — it is a question of fit. The LG 65QNED92AUA has a clear practical advantage for standard living spaces, while the TCL's footprint is purpose-built for dedicated home theater rooms or very large open-plan areas where its sheer scale is an asset rather than a constraint.

Across most of the features spec sheet, these two TVs are functionally identical — both ship with a built-in smart TV platform, support AirPlay, Google Assistant, smartphone remote control, USB recording, and voice commands, while sharing the same 0.5W standby power consumption and a one-year warranty. For the vast majority of users, the day-to-day smart TV experience will feel indistinguishable between the two.

The only concrete differentiator in this group is Amazon Alexa compatibility, which the LG 65QNED92AUA supports and the TCL 98QM6K does not. For households already embedded in the Amazon ecosystem — using Echo devices, Alexa routines, or smart home integrations — this gives the LG a tangible convenience edge, enabling voice control through existing Alexa infrastructure rather than relying solely on the TV's built-in microphone or Google Assistant. Notably, neither TV supports Siri or Apple HomeKit, so Apple-centric smart home users will find both options equally limited on that front despite the LG's AirPlay support.

The LG 65QNED92AUA holds a narrow edge in this category, purely on the strength of its Alexa support. It is not a sweeping advantage, but for Amazon ecosystem households it removes a meaningful friction point. For everyone else, features are effectively a tie.
