Hisense 100U75QG 100" VS TCL 98QM6K 98"

Both the Hisense 100U75QG and the TCL 98QM6K share the same fundamental display architecture — QLED Mini-LED LCD panels running at native 4K (3840 x 2160) resolution with 10-bit color depth and a wide 1.07 billion color palette. They also match across every HDR standard (HDR10, HDR10+, Dolby Vision, and HLG), adaptive sync (AMD FreeSync Premium Pro), anti-reflection coating, ambient light sensing, and a full 178° viewing angle in both axes. At this level of feature parity, the real-world picture quality baseline is essentially identical between the two.

Where they diverge is in screen size and refresh rate. The Hisense edges out with a 99.5″ physical panel versus the TCL's 97.5″ — a 2-inch difference that is barely perceptible in a side-by-side but does make the Hisense technically the larger canvas. Pixel density is a near-wash: 44 ppi on the Hisense versus 45 ppi on the TCL — a one-pixel-per-inch gap caused entirely by the size difference, with no meaningful visual consequence at typical large-screen viewing distances. The more impactful differentiator is the native refresh rate: the Hisense runs at 165Hz versus the TCL's 144Hz. For cinematic or broadcast content this distinction is irrelevant, but for console or PC gaming the Hisense's higher ceiling offers smoother motion and a competitive edge, especially since both already support AMD FreeSync Premium Pro for variable refresh rate.

On display specs alone, the Hisense 100U75QG holds a clear advantage for anyone who plans to use the TV for gaming, owing to its superior 165Hz refresh rate. For a dedicated home cinema viewer, the two are functionally equivalent — same panel type, same color volume, same HDR ecosystem, same viewing angles — making the choice between them a matter of price, size preference, and other feature groups rather than display performance.

The wired connectivity foundation is identical between the two TVs: both offer 4x HDMI 2.1 ports, 2x USB, a single RJ45 Ethernet port, and Miracast wireless display mirroring. HDMI 2.1 is particularly important at this screen size, as it supports 4K at 120Hz with full bandwidth — critical for next-generation console gaming and high-end PC output.

The meaningful differences emerge in wireless and audio connectivity. The Hisense 100U75QG supports Wi-Fi 6E (802.11ax) in addition to Wi-Fi 4 and 5, while the TCL 98QM6K tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6E unlocks the uncongested 6GHz band, translating to faster throughput, lower latency, and more reliable streaming in dense wireless environments — a genuine advantage for 4K HDR streaming or future-proofing in a crowded home network. On the Bluetooth side, the TCL holds a slight counter-edge with Bluetooth 5.4 versus the Hisense's 5.3, though the real-world difference between these two adjacent versions is negligible for typical TV use cases like connecting soundbars or headphones. More practically, the Hisense includes a 3.5mm headphone jack that the TCL omits entirely — a small but tangible convenience for users who want to plug in wired headphones directly.

Connectivity goes to the Hisense 100U75QG. Its Wi-Fi 6E support is a meaningful future-proofing advantage over the TCL's Wi-Fi 5 ceiling, and the inclusion of a 3.5mm audio jack adds everyday flexibility the TCL cannot match. The TCL's marginally newer Bluetooth version does not offset these gaps.

Across every audio specification provided, the Hisense 100U75QG and the TCL 98QM6K are in complete lockstep. Both carry the full Dolby audio stack — Dolby Digital, Dolby Digital Plus, Dolby Audio, and Dolby Atmos — alongside DTS:X for object-based surround decoding. Both also include a built-in subwoofer and stereo speakers, and both support HDMI ARC and eARC for lossless audio passthrough to external soundbars or AV receivers.

The presence of HDMI eARC on both is worth highlighting for home theater buyers: eARC allows uncompressed, high-bandwidth audio formats like Dolby TrueHD and DTS-HD Master Audio to pass through to a compatible soundbar or receiver — something the older ARC standard cannot do. Combined with Dolby Atmos and DTS:X decoding, both TVs are well-equipped as the audio hub of a serious home theater setup, not just a casual viewing room.

This group is an outright tie. Every audio feature, format, and output option is identical between the two products. The decision between them on audio grounds is simply impossible to make — buyers should look to other specification groups to differentiate.

Size and weight diverge notably between these two giants. The Hisense 100U75QG is the physically larger set — 2230.1 mm wide and 1282.7 mm tall — which follows naturally from its 99.5″ panel. The TCL 98QM6K comes in at 2180.1 mm wide and 1246.9 mm tall, a footprint difference of roughly 5 cm in each direction. In practice, that gap matters most during installation: wall mounting, furniture clearance, and room suitability all need to be measured against the full chassis dimensions, not just the screen diagonal.

The more striking gap is in depth and weight. The Hisense is 81.3 mm thick and weighs 63,503 g (roughly 63.5 kg), while the TCL is considerably slimmer at 64 mm and meaningfully lighter at 53,302 g (about 53.3 kg). That is a 10 kg difference — significant when it comes to wall-mount bracket load ratings, the number of people needed for installation, and how the TV sits on furniture. The TCL's lower volume figure (approximately 174,000 cm³ versus the Hisense's 232,000 cm³) underscores just how much more compact its chassis engineering is relative to its screen size. Both support VESA mounting and share identical operating temperature ranges, so those factors cancel out.

On design and physical form factor, the TCL 98QM6K has a clear practical advantage. Despite being only 2 inches smaller diagonally, it is substantially lighter and thinner, making it easier to handle, install, and integrate into a room — without any meaningful sacrifice in screen real estate.

The smart feature baseline is largely shared: both TVs offer a built-in smart platform, AirPlay, Google Assistant, smartphone remote control, USB recording, voice commands, and identical 0.5W standby consumption. For most users, this common ground covers the daily essentials comfortably. The one voice assistant difference worth flagging is that the Hisense 100U75QG adds Amazon Alexa compatibility, while the TCL 98QM6K does not. For households already invested in an Alexa ecosystem — smart lights, routines, connected devices — this is a genuine convenience advantage, enabling the Hisense to act as a hub within that environment rather than just a display.

The other differentiator is the warranty period: the Hisense covers 2 years versus the TCL's 1 year. On a flagship-class, large-format TV at this price tier, doubling the manufacturer coverage is a meaningful long-term value consideration. A second year of warranty protection reduces financial exposure during a period when any latent panel or electronics issues are most likely to surface.

Features go to the Hisense 100U75QG on the strength of two distinct advantages: broader voice assistant reach with Alexa support and a substantially more reassuring 2-year warranty. Neither difference is transformative on its own, but together they represent a meaningfully stronger ownership proposition — especially for users in Alexa-centric smart homes.
