Hisense 100U75QG 100" VS TCL 98QM7K 98"

Both the Hisense 100U75QG and the TCL 98QM7K share the same fundamental display architecture — QLED Mini-LED LCD panels with a native 4K (3840 x 2160) resolution, 10-bit color depth, and 1.07 billion colors. They also match on HDR support, covering HDR10, HDR10+, Dolby Vision, and HLG, meaning neither has a content-compatibility advantage. Both include anti-reflection coatings and ambient light sensors, and both offer wide 178° viewing angles in both axes — solid for large living rooms with varied seating positions.

The most meaningful differentiator between these two giants is the refresh rate: the Hisense reaches 165Hz versus the TCL's 144Hz. In practice, both far exceed the 60Hz of standard broadcast content, but for PC gaming or next-gen console titles that can push high frame rates, the Hisense's ceiling provides a tangible edge in motion fluidity and input responsiveness. Both support the full AMD FreeSync Premium Pro suite for variable refresh rate gaming, so the advantage is specifically in that raw upper ceiling. The screen size gap — 99.5″ for the Hisense versus 97.5″ for the TCL — is a marginal 2 inches and will be imperceptible in everyday use, and the pixel density is essentially identical at 44 vs 45 ppi.

For the vast majority of users — movie watchers, sports fans, and casual viewers — these two displays are effectively evenly matched on every spec that matters. The Hisense 100U75QG holds a narrow edge strictly for high-framerate gaming, thanks to its higher 165Hz refresh rate, but if gaming is not a priority, the display specs alone do not give either TV a decisive advantage.

The wired connectivity picture is identical across both TVs: four HDMI 2.1 ports, two USB ports, and a single RJ45 Ethernet jack. HDMI 2.1 is the current gold standard, supporting 4K at high refresh rates and uncompressed audio passthrough, so neither TV compromises on source device compatibility — whether that's a gaming console, Blu-ray player, or AV receiver.

Where these two diverge meaningfully is wireless. The Hisense 100U75QG supports Wi-Fi 6E (802.11ax) in addition to Wi-Fi 4 and 5, while the TCL 98QM7K tops out at Wi-Fi 5 (802.11ac). In practical terms, Wi-Fi 6E unlocks the 6GHz band — a less congested spectrum that delivers lower latency and more consistent throughput in households with many connected devices. For 4K streaming, this can translate to a more stable connection and less buffering, especially in dense wireless environments. On Bluetooth, the TCL has a slight specification lead with version 5.4 versus the Hisense's 5.3, though the real-world difference between these two incremental versions is negligible for typical TV use cases like pairing a soundbar or headphones.

On connectivity overall, the Hisense 100U75QG holds the clearer advantage. The Wi-Fi 6E support is a genuinely useful upgrade over Wi-Fi 5 for future-proofing and network performance in busy homes, while the TCL's marginal Bluetooth version lead does not meaningfully offset that gap.

Audio is the rare category where these two TVs are in complete lockstep. Both carry an identical feature set: built-in stereo speakers with a dedicated subwoofer, full support for Dolby Atmos, Dolby Audio, Dolby Digital, and Dolby Digital Plus, as well as DTS:X — covering the two dominant object-based surround sound formats used across streaming platforms, Blu-ray, and gaming. For buyers who plan to run content through the TV's own speakers, both are equally well-equipped to decode and render immersive audio without an external processor.

Equally matched on the output side, both TVs include both HDMI ARC and eARC. The eARC port is the more significant of the two — it carries enough bandwidth to pass lossless audio formats like Dolby TrueHD and DTS-HD Master Audio directly to a compatible soundbar or AV receiver, bypassing any lossy compression. For users planning to invest in a premium external audio setup, this matters more than the built-in speaker configuration.

There is no basis for declaring a winner here — the Hisense 100U75QG and TCL 98QM7K are perfectly tied on audio specifications. Every format, every port, every built-in speaker feature is identical. The audio experience on either TV will come down entirely to hardware implementation — speaker tuning, amplifier quality, and cabinet acoustics — none of which are reflected in these specs.

Given that these are both massive screens, physical design becomes a genuinely practical concern — and the differences here are more substantial than the screen size gap might suggest. The TCL 98QM7K is noticeably slimmer at 60.9 mm deep compared to the Hisense's 81.3 mm, a difference of over 20 mm that is immediately visible in a room and relevant for wall-proximity placement or console-style mounting.

The weight gap is even more striking. The Hisense 100U75QG weighs in at 63,503 g (roughly 140 lbs), while the TCL comes in at 55,293 g (approximately 122 lbs) — a difference of over 8 kg. At this scale, that delta has real logistical implications: wall mount load ratings, the number of people needed for installation, and long-term stress on mounting hardware all scale with weight. The TCL's lower volume — 165,514 cm³ versus 232,563 cm³ — further confirms it is the more compact chassis overall, despite only being 2 inches smaller diagonally. Both support VESA mounting and share identical operating temperature ranges, so neither has an environmental advantage.

On design and physical footprint, the TCL 98QM7K has a clear practical advantage. It is meaningfully lighter and significantly thinner, making it easier to install, safer to wall-mount, and less imposing in the room — all without sacrificing much screen real estate.

Across the smart features landscape, these two TVs are remarkably aligned. Both run a built-in smart TV platform with voice command support via Google Assistant and Alexa, both support AirPlay for iOS and macOS mirroring, and both allow smartphone remote control. Neither supports Apple HomeKit/Siri, so HomeKit household users will find the same limitation on either set. USB recording, sleep timers, child lock, and a standby draw of just 0.5W are all shared — there is genuinely nothing to separate them on day-to-day smart functionality.

The sole differentiator in this entire category is the warranty period: the Hisense 100U75QG covers 2 years, while the TCL 98QM7K offers just 1 year. For televisions at this size and price tier, warranty coverage carries real financial weight — a panel replacement or repair on a 100-class TV outside of warranty can be a significant cost. An extra year of manufacturer protection is a tangible, quantifiable benefit.

The Hisense 100U75QG edges out the TCL in this category on the strength of its 2-year warranty alone. It is the only meaningful difference in an otherwise identical feature set, but for a high-stakes, large-format purchase, longer coverage is a practical advantage that buyers should factor into their decision.
