Samsung QA77S95FAWXXY 77" VS Samsung QN83S90FAE 83"

Both the Samsung QA77S95FAWXXY 77″ and the Samsung QN83S90FAE 83″ share the same fundamental display DNA: OLED/AMOLED panels running at 4K (3840 x 2160) resolution with 10-bit color depth and 1.07 billion colors. Their HDR support is identical — HDR10, HDR10+, and HLG are all present on both, while neither supports Dolby Vision. Viewing angles, anti-reflection coating, ambient light sensor, and AMD FreeSync Premium Pro adaptive sync are likewise shared across both models, meaning the core image quality foundation is very similar.

Where the two diverge meaningfully is in screen size, pixel density, and refresh rate. The QN83S90FAE's larger 82.5″ panel naturally commands more physical presence, but its pixel density drops to 53 ppi versus the QA77S95FAWXXY's 57 ppi — a difference that becomes perceptible at closer viewing distances, where the 77″ will render fine detail and text with slightly more crispness. On the motion side, the 77″ holds a notable advantage with a 165Hz refresh rate compared to the 83″'s 144Hz. In practice, both are well above the threshold where most content looks fluid, but 165Hz provides a tangible edge for fast-paced gaming, where every frame counts.

In summary, the QA77S95FAWXXY 77″ has a clear edge in display sharpness and refresh rate — making it the stronger pick for gaming and closer-proximity viewing. The QN83S90FAE 83″ trades those advantages for a larger screen surface, which suits dedicated home-theater setups where viewing distance naturally offsets the lower pixel density. Neither product supports Dolby Vision, so that is not a differentiator here.

The connectivity foundations of both TVs are nearly identical and solidly modern: four HDMI 2.1 ports, a wired RJ45 ethernet port, Wi-Fi 5 (802.11ac), Bluetooth 5.3, and Miracast wireless mirroring are all present on both models. HDMI 2.1 is particularly important at this screen size and refresh rate tier, as it supports the bandwidth needed for 4K high-frame-rate signals from gaming consoles and PCs without compromise.

Two differences are worth noting. First, the QA77S95FAWXXY 77″ edges ahead with 4 USB ports versus 3 on the QN83S90FAE 83″ — a small but practical advantage when juggling multiple peripherals like USB storage drives, keyboards, or streaming sticks simultaneously. Second, and more significantly, the QN83S90FAE 83″ supports a broader set of DVB tuner standards: in addition to the DVB-T/T2 terrestrial tuners both share, it adds DVB-C, DVB-S, and DVB-S2 — enabling direct connection to cable and satellite antenna systems without an external set-top box. For users in regions where cable or satellite is the primary broadcast medium, this is a meaningful built-in capability.

Overall, connectivity is a near-tie, but the edge shifts depending on use case: the 77″ QA77S95FAWXXY wins marginally on USB flexibility, while the 83″ QN83S90FAE holds a clear advantage for anyone relying on cable or satellite broadcast reception.

Audio is the one specification group where these two TVs are in complete lockstep — every single provided spec is identical. Both feature stereo speakers, a built-in subwoofer, Dolby Atmos and Dolby Audio support, digital audio output, and both HDMI ARC and eARC. The presence of eARC is particularly relevant for home theater setups, as it carries enough bandwidth to pass lossless audio formats like Dolby TrueHD and DTS:X to a compatible soundbar or AV receiver without compression — something the older ARC standard cannot do.

Neither model supports Dolby Virtual or SRS TheaterSound HD, so neither has a spatial audio processing advantage over the other on the software side either. The subwoofer inclusion suggests both are tuned for fuller low-frequency response out of the box, which benefits bass-heavy content like action films and music without requiring an external speaker system.

This group is a complete tie. There is no audio specification in the provided data that distinguishes the QA77S95FAWXXY 77″ from the QN83S90FAE 83″, and neither product holds any advantage here. Audio performance should not be a factor in choosing between these two models.

The most striking physical difference between these two TVs is thickness. The QA77S95FAWXXY 77″ measures just 11.2 mm thin — an exceptionally svelte profile that makes it a strong candidate for flush wall mounting, where it will sit almost flush against the surface like a framed canvas. The QN83S90FAE 83″, by contrast, is 44.9 mm thick — four times deeper. This directly explains the volume gap: the 83″ displaces over 88,000 cm³ versus roughly 18,900 cm³ for the 77″, meaning the larger TV has a far more conventional, box-like physical presence that will be noticeable both on a stand and when wall-mounted.

Weight tells an interesting counter-intuitive story. Despite its smaller screen, the QA77S95FAWXXY 77″ is actually heavier at 40 kg compared to the QN83S90FAE 83″'s 37.6 kg. This likely reflects differences in internal construction and panel technology between the two models. In practical terms, both are heavy enough that professional installation is advisable, though the 83″ offers a slight handling advantage. Both support VESA mounting, so third-party wall bracket compatibility is ensured for either.

For design, the QA77S95FAWXXY 77″ holds a clear advantage for anyone prioritizing a sleek, low-profile aesthetic — particularly for wall installations where minimal depth is a priority. The QN83S90FAE 83″ wins on raw screen footprint and is marginally easier to maneuver, but its substantially greater thickness makes it less suited to minimalist or flush-mount setups.

Feature parity between these two TVs is remarkably high. Both run a full smart TV platform with AirPlay, Google Assistant, and Alexa voice control built in — though neither supports Siri or Apple HomeKit, which is worth noting for users deeply embedded in the Apple ecosystem. Smartphone remote support, USB recording, a rechargeable remote, and a standard one-year warranty are also shared across both models, leaving virtually no daylight between them on the smart features front.

The only measurable differentiator in this group is power consumption. The QA77S95FAWXXY 77″ draws 216W during operation, while the larger QN83S90FAE 83″ consumes 237W — a difference of 21W. Over extended daily use, that gap accumulates: assuming five hours of viewing per day, the 83″ would consume roughly an additional 38 kWh per year compared to the 77″. Standby draw is identical at 0.5W for both, so the difference is purely in active use.

This group is essentially a tie on features, with the QA77S95FAWXXY 77″ holding a minor edge in energy efficiency. Unless long-term electricity cost is a deciding factor, neither TV offers a meaningful functional advantage over the other here — the smart platform, voice assistant ecosystem, and usability tools are identical in every practical respect.
