LG OLED55C5PUA 55" VS Samsung QA83S95FAEXXY 83"

Both the LG OLED55C5PUA and the Samsung QA83S95FAEXXY share a strong foundation: identical OLED/AMOLED panel technology, 4K (3840 x 2160) resolution, 10-bit color depth rendering 1.07 billion colors, and symmetrical 178° viewing angles in both axes. They also both include anti-reflection coating and an ambient light sensor, meaning neither cuts corners on everyday usability. The critical divergence begins with size and pixel density — the LG's 55.2″ screen achieves a noticeably sharper 80 ppi, while the Samsung's much larger 83.5″ panel drops to 53 ppi. In practical terms, this means fine text and detail will appear crisper on the LG at typical viewing distances, whereas the Samsung's lower pixel density only becomes imperceptible when seated further away, as is common with very large screens.

On motion handling, the Samsung holds a clear advantage with a 165Hz refresh rate versus the LG's 120Hz. The extra headroom matters most for high-frame-rate gaming and fast-paced content, where the Samsung will render motion more smoothly. For HDR format support, the two products diverge in opposite directions: the LG supports Dolby Vision but not HDR10+, while the Samsung supports HDR10+ but not Dolby Vision. This is a meaningful practical split — Dolby Vision dominates streaming platforms like Netflix and Apple TV+, while HDR10+ is more prevalent on Amazon Prime Video and Samsung's own ecosystem. Neither format is universally superior in quality, so the better choice depends on where you primarily consume content.

For adaptive sync, the LG adds Nvidia G-Sync compatibility alongside AMD FreeSync Premium, giving it broader compatibility across both major GPU brands — a genuine edge for PC gamers. The Samsung is limited to AMD FreeSync tiers only. Overall, the Samsung wins on sheer screen real estate and refresh rate, making it the stronger choice for immersive large-room viewing and high-framerate gaming on AMD hardware. The LG, however, has the edge in pixel sharpness, Dolby Vision support, and wider GPU compatibility, making it the more versatile all-rounder for mixed use at a more intimate viewing distance.

The wired backbone of both TVs is essentially identical: 4x HDMI 2.1 ports, a single RJ45 ethernet jack, Bluetooth 5.3, and Miracast support — a solid, modern setup that will satisfy most users. Where the two diverge meaningfully is in wireless networking. The LG supports Wi-Fi 6 and Wi-Fi 6E in addition to older standards, while the Samsung tops out at Wi-Fi 5 (802.11ac). In practical terms, Wi-Fi 6E unlocks the 6GHz band, which is less congested and capable of significantly higher throughput — a real advantage in busy households with many connected devices, or when streaming uncompressed 4K content over a network.

The Samsung counters with one extra USB port — 4 vs. 3 on the LG — which is a minor but occasionally useful convenience for simultaneously connecting external drives, keyboards, or other peripherals without needing a hub. On broadcast tuner support, the LG holds a broader hand: it includes DVB-C, DVB-S, and DVB-S2 in addition to the terrestrial DVB-T/T2 standards that the Samsung covers. This matters for users who rely on cable or satellite reception directly through the TV's built-in tuner, as the Samsung would require an external receiver for those signal types.

Connectivity overall gives the LG OLED55C5PUA a clear edge. Its Wi-Fi 6E support is the most impactful differentiator in modern home networking, and its wider DVB tuner range adds genuine versatility for broadcast viewers. The Samsung's extra USB port is a convenience rather than a competitive advantage, making the LG the stronger performer in this category.

Across every audio specification provided, the LG OLED55C5PUA and the Samsung QA83S95FAEXXY are a perfect match. Both feature stereo speakers with a built-in subwoofer, support Dolby Atmos and Dolby Audio, and offer both HDMI ARC and eARC — the latter being the more important of the two, as eARC carries high-bandwidth audio formats like Dolby Atmos TrueHD and DTS:X losslessly to a connected soundbar or AV receiver. Digital audio output is also present on both, ensuring compatibility with older external audio equipment.

This is a straightforward draw. Based strictly on the provided specs, neither TV holds any audio advantage over the other — every feature and format listed is shared equally. Buyers prioritizing audio capability should look beyond this spec group, as the differentiating factors will lie elsewhere.

Size naturally dominates this category: the Samsung QA83S95FAEXXY is a substantially larger panel, and its physical dimensions reflect that — 1844.2 mm wide and 1056.8 mm tall versus the LG's 1221.7 x 703.6 mm footprint. The weight gap is even more striking, with the Samsung coming in at 51,900 g (roughly 52 kg) compared to the LG's 16,012 g (about 16 kg). For installation, this means the Samsung will almost certainly require two people and potentially wall-reinforcement checks before mounting, while the LG is considerably more manageable to position and reposition.

The most surprising figure is thickness. Despite being a much larger TV, the Samsung is dramatically slimmer at just 12.6 mm — less than a third of the LG's 45.7 mm depth. This makes the Samsung a far more striking wall-mounted installation, sitting almost flush against the surface. The LG, by contrast, will protrude noticeably more when wall-mounted, which may matter in spaces where a sleek, low-profile aesthetic is a priority. Interestingly, the Samsung's extreme thinness results in a lower total volume despite its larger screen area — a testament to how aggressively its chassis has been engineered. Both TVs support VESA mounting, so neither has an advantage on that front.

The verdict here depends entirely on the use case. The Samsung wins decisively on profile aesthetics with its near-borderline 12.6 mm thinness, but its ~52 kg weight makes installation a serious physical undertaking. The LG is far lighter and easier to handle, but its greater depth will be more visually prominent on a wall. Neither is objectively superior — the right choice hinges on room size, installation support available, and how much the slim-profile aesthetic matters to the buyer.

Smart platform parity is nearly total between these two TVs: both run a built-in smart TV OS, support AirPlay, Google Assistant, Alexa, USB recording, voice commands, and smartphone remote control. Neither supports Apple HomeKit, and both share an identical 0.5W standby draw. The one small but practical differentiator here is the Samsung's rechargeable remote control — the LG ships with a conventional battery-powered remote. Over months of use, not having to replace batteries is a minor but genuinely appreciated convenience.

The most consequential numbers in this group are power-related. The LG draws 133.1W during operation versus the Samsung's 248W — nearly double. Projected over a year, that translates to an estimated 246 kWh for the LG against 908 kWh for the Samsung. At typical residential electricity rates, that gap represents a significant real-world cost difference annually. Much of this disparity is attributable to the Samsung's far larger screen area rather than efficiency shortcomings per se, but the outcome for the user's electricity bill is the same regardless of cause.

For this spec group, the LG OLED55C5PUA holds a meaningful advantage on power efficiency — the annual consumption gap is too large to dismiss. The Samsung edges ahead only on the rechargeable remote, which is a convenience rather than a capability. Users who watch several hours of TV daily and are mindful of running costs will find the LG's energy footprint substantially easier to live with.
