Samsung QN115QN90FFXZA 115" VS TCL 98X11K 98"

Both the Samsung QN115QN90F and the TCL 98X11K share the same fundamental display architecture — QLED Mini-LED LCD panels with a 4K (3840 x 2160) resolution, 10-bit color depth, 1.07 billion colors, a 144Hz refresh rate, and identical 178° horizontal and vertical viewing angles. Both also support the same HDR formats (HDR10, HDR10+, HLG), carry anti-reflection coatings, ambient light sensors, and the full AMD FreeSync Premium Pro adaptive sync stack. For everyday viewing and gaming, these shared traits mean the two TVs deliver a broadly similar visual experience at their respective sizes.

The most meaningful differentiator is size, and with it, pixel density. The Samsung stretches to 114.5″, producing a 38 ppi density, while the TCL measures 97.5″ at 45 ppi. That 7 ppi gap is noticeable: at typical living-room viewing distances the TCL will render slightly sharper fine detail and text, while the Samsung's sheer canvas delivers a more immersive, cinematic sense of scale. The right choice depends entirely on room size and seating distance — the Samsung rewards larger spaces, the TCL rewards closer seating. The other key differentiator is HDR ecosystem: the TCL adds Dolby Vision support, which the Samsung lacks. Dolby Vision uses dynamic, scene-by-scene metadata and is widely available on streaming platforms (Netflix, Disney+, Apple TV+), meaning the TCL can extract more precisely optimized HDR from a broader library of content.

In summary, these two TVs are closely matched on core display technology, but each holds one clear advantage in its category. The TCL 98X11K has the edge in display capability thanks to Dolby Vision compatibility and higher pixel density. The Samsung QN115QN90F counters with an unmatched 114.5″ screen size for buyers who prioritize maximum visual immersion above all else.

The connectivity foundations of both TVs are nearly identical: 4 HDMI 2.1 ports, 2 USB ports, a single RJ45 ethernet port, Miracast screen mirroring, and Wi-Fi 5 as a shared wireless baseline. HDMI 2.1 is the standout shared strength here — it supports 4K at 144Hz and features like VRR and eARC, so both TVs are equally well-equipped for next-gen consoles and high-bandwidth audio passthrough without needing an adapter or workaround.

The differences are incremental but real. On the wireless side, the TCL 98X11K adds Wi-Fi 6 (802.11ax) support, which the Samsung does not offer. Wi-Fi 6 delivers meaningfully better performance in congested network environments — faster throughput, lower latency, and more efficient handling of multiple simultaneous devices — making it a genuine advantage in busy households. On the Bluetooth side, the TCL carries Bluetooth 5.4 versus the Samsung's Bluetooth 5.3; the gap is minor in practice, but 5.4 brings slightly improved connection reliability and power efficiency for wireless audio accessories.

The TCL 98X11K holds a clear, if modest, edge in connectivity. Its Wi-Fi 6 support is the more impactful upgrade — particularly for users who rely on wireless streaming or operate in dense Wi-Fi environments — while its newer Bluetooth version adds a marginal refinement on top. The Samsung matches the TCL in wired and physical port configuration, but falls a generation behind on wireless standards.

Across every audio specification provided, the Samsung QN115QN90F and the TCL 98X11K are a perfect match. Both feature stereo speakers with a built-in subwoofer, which is a meaningful inclusion at this tier — an integrated subwoofer adds low-frequency weight to on-screen audio without requiring an external soundbar for casual viewing. Both also support Digital Out for routing audio to an external receiver, and both include HDMI ARC and eARC, the latter being particularly important as eARC supports high-bandwidth, uncompressed audio formats like Dolby TrueHD and DTS:X when paired with a compatible soundbar or AV receiver.

Based strictly on the provided specs, this group is a complete tie. There is no differentiator between the two TVs on audio — every listed capability is shared identically. Buyers prioritizing audio quality should look beyond this spec group, as the on-board audio configuration will not be a deciding factor between these two models.

Size differences of this magnitude carry real logistical weight — literally. The Samsung QN115QN90F measures 2565 mm wide and tips the scale at 86 kg, while the TCL 98X11K comes in at 2177 mm wide and 70.3 kg. That is a roughly 16 kg difference, which has direct implications for installation: the Samsung will require more personnel to maneuver safely, may not clear standard doorframes without careful planning, and demands a wall or stand capable of handling its mass. The TCL, though still a substantial display, is meaningfully more manageable in all of these respects.

Depth and volume tell a similar story. The Samsung is 33 mm thick with a total volume of approximately 124,287 cm³, versus the TCL's slimmer 27 mm profile and 73,239 cm³ footprint — less than 60% of the Samsung's volumetric bulk. The thinner chassis of the TCL will sit closer to the wall on a VESA mount, which both TVs support, and gives it a more contemporary silhouette. On operating temperature range, the Samsung tolerates up to 40 °C with a minimum of 10 °C, while the TCL operates between 5 °C and 35 °C — the TCL handles cooler environments better, the Samsung handles warmer ones, though neither difference is likely to matter in a typical climate-controlled room.

For the Design group, the TCL 98X11K has a practical advantage in handling, installation, and wall presence thanks to its significantly lower weight, slimmer depth, and smaller overall footprint. The Samsung's larger dimensions are an inherent consequence of its bigger screen, so buyers choosing it should plan accordingly for delivery, installation support, and room clearance.

Feature parity between these two TVs is remarkably high. Both offer a full smart TV platform with Chromecast built-in, AirPlay, Google Assistant, smartphone remote control, USB recording, a rechargeable remote, and an identical 0.5W standby power consumption. For the vast majority of users, the day-to-day smart TV experience will feel essentially the same across both models.

The sole differentiator in this group is voice assistant ecosystem breadth. The Samsung QN115QN90F adds Amazon Alexa compatibility, which the TCL lacks. This matters specifically to users who have already built out an Alexa-based smart home — being able to control the TV via existing Echo devices, or trigger routines that include the TV, is a genuine convenience advantage. For households centered on Google Assistant or with no smart home infrastructure at all, this distinction is largely irrelevant.

The Samsung QN115QN90F holds a narrow edge in this group purely on the strength of its Alexa support. It is not a transformative advantage, but for Amazon ecosystem users it is a practical one. Everyone else will find the two TVs functionally identical in features.
