Hisense 100U8QG 100" VS TCL 98C8K 98"

Both the Hisense 100U8QG and the TCL 98C8K share the same fundamental display architecture — Mini-LED-backlit QLED LCD panels running at native 4K (3840 x 2160) resolution with 10-bit color depth and 1070 million colors. Their HDR support is also identical, covering HDR10, HDR10+, Dolby Vision, and HLG, meaning neither has an edge in format compatibility. Anti-reflection coating and ambient light sensors are present on both, and viewing angles are a matching 178° horizontally and vertically, making side-by-side seating equally comfortable on either set.

The single most meaningful differentiator in this group is the refresh rate: the Hisense runs at 165Hz versus the TCL's 144Hz. For the vast majority of TV viewing — streaming, cable, even 4K Blu-ray — neither rate offers a visible advantage over a standard 60Hz panel. However, for PC gaming or next-generation console content that can push high frame rates, the Hisense's 165Hz ceiling provides slightly smoother motion and a marginally lower latency ceiling. Both sets support the full AMD FreeSync Premium Pro stack, so variable refresh rate gaming is well-covered regardless of choice. The Hisense is also physically larger at 99.5″ versus 98″, a difference too small to influence a buying decision on its own.

Overall, the displays are nearly identical in capability. The Hisense 100U8QG holds a narrow edge for gaming-focused buyers specifically because of its higher 165Hz refresh rate; for pure home-theater use, the two panels are effectively tied, and the TCL 98C8K's marginally higher pixel density of 45 ppi versus 44 ppi is too negligible to perceive at typical viewing distances.

Wired connectivity splits in opposite directions between these two sets. The TCL 98C8K offers 4 HDMI 2.1 ports to the Hisense's 3, a genuine practical advantage for users running multiple 4K sources simultaneously — think a gaming console, a streaming stick, a soundbar, and an AV receiver all connected without a switch. The Hisense 100U8QG counters with 2 USB ports versus the TCL's single port, which matters for users who want to connect both a USB drive and a peripheral, or who frequently swap between storage devices.

On the wireless side, the Hisense pulls ahead more meaningfully. Its Wi-Fi 6E support — versus the TCL's Wi-Fi 6 ceiling — opens access to the less congested 6 GHz band, translating to more stable throughput in apartment buildings or households with many connected devices. For 4K streaming and large app downloads, this can reduce buffering and improve responsiveness noticeably. Bluetooth tells a similar but smaller story: the TCL's Bluetooth 5.4 is a step newer than the Hisense's 5.3, though the real-world difference in range or stability at this gap is negligible for standard headphone or remote pairing use cases.

One further distinction worth flagging: the Hisense includes a 3.5mm audio jack, which the TCL omits entirely. This is a minor but practical convenience for users who prefer wired headphone listening without routing through an external device. On balance, the connectivity decision hinges on use case — the TCL is better suited for source-heavy home theater setups needing more HDMI ports, while the Hisense holds the broader edge for wireless performance thanks to Wi-Fi 6E, plus its extra USB port and headphone output.

Across every audio specification in this group, the Hisense 100U8QG and the TCL 98C8K are a complete match. Both include stereo speakers with a built-in subwoofer, support the full Dolby suite — Dolby Digital, Dolby Digital Plus, Dolby Atmos, and Dolby Audio — and also carry DTS:X decoding. In practice, this means both sets can process object-based surround sound natively, whether the source is a streaming service, a Blu-ray player, or a gaming console, without requiring an external receiver to handle the decoding.

Equally important for home theater integration, both televisions offer 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 lossy compression. Users planning a premium external audio setup will find both TVs equally capable partners for high-end sound systems.

This group is a straightforward tie. There is no differentiator — not a single audio specification separates these two sets. Buyers prioritizing audio capability have no reason to favor one over the other based on this data alone, and should focus their decision on the differences identified in other specification groups.

At this screen size tier, both televisions are substantial physical objects, but the numbers reveal a meaningful gap in how they handle that bulk. The TCL 98C8K weighs in at 56 kg, while the Hisense 100U8QG tips the scale at 63.5 kg — a difference of roughly 7.5 kg that has direct implications for installation. At these weights, both sets require at least two people and ideally professional mounting, but the TCL places noticeably less stress on wall mounts, furniture, and the people carrying it into position.

The thickness gap is even more striking in relative terms. The Hisense measures 81.3 mm deep compared to the TCL's 54 mm — nearly 50% slimmer for the TCL. On a wall mount this translates to a set that sits far closer to the wall surface, a meaningful aesthetic difference in living room installations where a protruding panel can feel visually heavy. The resulting volume difference — 144,568 cm³ for the TCL versus 232,563 cm³ for the Hisense — reinforces just how much more compact the TCL chassis is despite the screen sizes being close. Both sets support VESA mounting and share identical operating temperature ranges, so neither has an edge on installation flexibility or environmental tolerance.

For design and physical footprint, the TCL 98C8K holds a clear advantage. Its significantly lower weight and slimmer profile make it easier to install, less demanding on mounting hardware, and more visually unobtrusive on a wall — all without any trade-off in the specs provided here.

The smart feature sets of these two televisions are remarkably aligned. Both run a built-in smart TV platform with Google Assistant and Alexa voice control, support AirPlay for Apple device mirroring, allow smartphone remote control, and include USB recording — a convenient feature for capturing live broadcasts directly to an external drive without a separate recorder. Neither set supports Apple HomeKit/Siri integration, so users embedded in the Apple smart home ecosystem will find the same limitation on both sides.

With shared standby consumption of 0.5W, sleep timers, child locks, and browser access all present on both, there is genuinely nothing in the day-to-day smart TV experience that separates these two sets based on the provided data. The feature parity here is as complete as it was in the audio group.

The sole differentiator — and it is a consequential one for long-term ownership — is the warranty period. The Hisense 100U8QG covers two years, while the TCL 98C8K offers only one. On a large-screen television at this price tier, an extra year of manufacturer coverage provides meaningful financial protection against panel or component failures. That single factor gives the Hisense a clear edge in this group, even though everything else is evenly matched.
