Samsung QN100QN80FF 100" VS Sony Bravia K-98XR50 98"

Both the Samsung QN100QN80FF and the Sony Bravia K-98XR50 share the same foundational display DNA: native 4K UHD resolution (3840 x 2160 px), 10-bit color depth, 1070 million displayable colors, identical 178º viewing angles in both axes, anti-reflection coatings, and ambient light sensors. At their respective sizes — 99.5″ for the Samsung and 97.5″ for the Sony — pixel density is virtually identical at 44 vs. 45 ppi, meaning sharpness per inch is a non-issue for either screen at normal viewing distances.

The two most meaningful differentiators are refresh rate and HDR ecosystem support. The Samsung's 144Hz panel versus the Sony's 120Hz is a tangible advantage for fast-motion content and gaming — higher refresh reduces motion blur and enables smoother frame interpolation. On HDR, the split is a deliberate trade-off: the Samsung supports HDR10+ (the dynamic metadata standard backed by Samsung and Amazon) but lacks Dolby Vision, while the Sony supports Dolby Vision (the dominant premium HDR format used by Netflix, Apple TV+, and Disney+) but drops HDR10+. Both cover HDR10 and HLG as baselines. In practice, Dolby Vision has broader streaming platform adoption today, which may make the Sony the safer choice for content availability — though neither format is universally superior in image quality terms.

Overall, the Samsung holds a clear edge in refresh rate, making it the stronger pick for gamers and sports viewers. The Sony counters with Dolby Vision support, which is the more widely deployed premium HDR format across major streaming services. The right choice depends on use case: the Samsung is better suited for high-frame-rate performance, while the Sony is the more practical option for HDR streaming breadth.

Connectivity between these two televisions is nearly identical across most dimensions — both carry 4x HDMI 2.1 ports, 2 USB ports, a single RJ45 ethernet port, Bluetooth 5.3, Wi-Fi 5, and Miracast support. HDMI 2.1 across all four ports is a genuine strength shared by both, enabling 4K@120Hz passthrough and high-bandwidth sources on every input simultaneously — a meaningful advantage for multi-device setups.

The one concrete differentiator is Wi-Fi. The Samsung tops out at Wi-Fi 5 (802.11ac), while the Sony adds support for Wi-Fi 6 (802.11ax). In practice, Wi-Fi 6 offers improved throughput, better performance in congested network environments with many connected devices, and lower latency — all relevant in a modern smart home. For most users streaming 4K content, Wi-Fi 5 is technically sufficient, but Wi-Fi 6 provides meaningful headroom and future-proofing, especially as home networks grow more crowded.

The Sony holds a clear edge in wireless connectivity purely due to its Wi-Fi 6 support. Everything else is a dead heat. If your home network already runs a Wi-Fi 6 router, the Sony will make better use of it; if not, this advantage is effectively dormant until you upgrade your infrastructure.

For the most part, these two televisions are evenly matched on audio: both support Dolby Atmos, Dolby Audio, stereo speakers, Digital Out, and HDMI ARC/eARC. The presence of eARC on both is worth noting — it carries enough bandwidth for lossless audio formats like Dolby TrueHD and DTS:X to pass through to a compatible soundbar or AV receiver, which matters for users who plan to build out a home theater system around either TV.

The single hardware differentiator is that the Samsung includes a built-in subwoofer, while the Sony does not. A subwoofer handles low-frequency reproduction — the rumble of explosions, the weight of a bass line, the impact of a film score. Without one, the Sony's internal speaker system will inherently produce thinner, less grounded bass from its built-in audio alone. For viewers relying primarily on the TV's own speakers rather than an external audio setup, this is a tangible gap in everyday listening experience.

The Samsung holds a clear audio advantage for standalone use thanks to its integrated subwoofer. If you plan to pair either TV with a dedicated soundbar or surround system anyway, the gap narrows significantly — eARC support on both ensures high-quality external audio passthrough. But as a self-contained unit, the Samsung delivers a more complete out-of-the-box sound profile.

The most striking difference in this category is weight. The Samsung tips the scales at 27.4 kg, while the Sony comes in at a substantial 69 kg — more than two and a half times heavier. At this size class, no television is trivially easy to install, but the Sony's mass has serious practical implications: wall mounting will demand a heavy-duty bracket rated for the load, and installation will almost certainly require multiple people and careful structural assessment of the wall itself. The Samsung, by comparison, is considerably more manageable for delivery, positioning, and mounting.

Thickness follows a similar pattern. The Samsung measures 58.4 mm deep versus the Sony's 85 mm — a 45% difference that affects both wall-mount protrusion and how the TV sits on a stand in a room. The resulting volume difference (roughly 166,000 cm³ vs. 235,000 cm³) reinforces that the Sony is a physically much bulkier unit despite being only about 2 inches smaller diagonally. One minor but practical edge the Sony holds is a lower minimum operating temperature of 0 °C versus the Samsung's 10 °C, which could matter for installations in unheated spaces like garages or conservatories in colder climates.

On design and physical footprint, the Samsung has a clear advantage — it is dramatically lighter, meaningfully slimmer, and easier to handle and install. Both support VESA mounting, but the Sony's weight will impose significantly higher infrastructure demands. Unless the colder operating range is specifically relevant to your installation environment, the Samsung is the more practical physical proposition by a wide margin.

Across the smart feature landscape, these two televisions are remarkably well-matched. Both offer AirPlay, Google Assistant, Alexa, smartphone remote support, USB recording, voice commands, and a full suite of convenience features like sleep timer and child lock — all under the same 1-year warranty. Neither supports Siri/Apple HomeKit, so Apple ecosystem users will find the same limitation on both. For day-to-day smart TV usability, there is effectively no functional gap between them.

Two specs stand out as genuine differentiators. First, the Sony includes a rechargeable remote control, which the Samsung lacks — a small but appreciated quality-of-life feature that eliminates the recurring cost and inconvenience of replacing disposable batteries. Second, and more significantly, power consumption diverges sharply: the Samsung draws 357W during operation versus the Sony's 600W — nearly 70% more. At typical usage levels, that difference compounds meaningfully over time in electricity costs, and it also reflects the greater thermal and electrical infrastructure demands of the Sony's larger, heavier panel assembly.

On balance, the Samsung holds a clear edge in operating efficiency, and the Sony's only exclusive perk is its rechargeable remote. For users who are cost- or energy-conscious, the Samsung's substantially lower power draw is the more impactful differentiator in this group. The Sony's rechargeable remote is a convenience win, but it does not offset the gap in running costs over the lifespan of the TV.
