LG 75QNED82AUA 75" VS Philips 75PUS7800/12 75"

At the foundational level, the LG 75QNED82AUA and Philips 75PUS7800/12 are remarkably similar: both deliver a 4K (3840 x 2160) resolution at 59 ppi, share a 10-bit panel capable of rendering 1.07 billion colors, run at a 60Hz refresh rate, and offer identical 178° viewing angles in both axes. Anti-reflection coatings and ambient light sensors are also present on both, meaning neither holds an advantage in everyday ergonomics or glare management.

The most meaningful hardware distinction lies in the backlighting technology. The LG uses a Mini-LED backlight, which employs a much larger number of smaller LEDs to enable finer local dimming zones — this typically translates to deeper blacks, better contrast control, and reduced blooming around bright objects on dark backgrounds. The Philips, by contrast, relies on a QLED approach, which uses quantum dots to enhance color volume and brightness but without the same granular dimming precision of Mini-LED. In practice, the LG has a structural edge in scenes with mixed light and dark content, while the Philips may hold its own in overall color saturation.

On the HDR front, both support HDR10 and HLG, but the Philips adds HDR10+ — a dynamic metadata format that adjusts tone-mapping scene by scene rather than using a single static profile. Neither TV supports Dolby Vision. Since HDR10+ content is increasingly available on platforms like Amazon Prime Video and Samsung's ecosystem, the Philips has a tangible advantage for users who consume that content. Overall, the LG holds an edge in display hardware through its Mini-LED panel, while the Philips counters with broader HDR format coverage via HDR10+ — making the choice dependent on whether contrast performance or HDR compatibility matters more to the buyer.

The wireless and wired backbone of both TVs is largely identical: each offers HDMI 2.1 across all three HDMI ports, a single RJ45 ethernet port, matching Wi-Fi 5 (802.11ac) support, and Miracast for screen mirroring. For most home theater setups, this shared foundation means neither TV will bottleneck modern devices — HDMI 2.1 handles 4K at 60Hz and supports features like eARC without issue.

Where the Philips pulls ahead is in the smaller but practically relevant details. It offers 2 USB ports versus the LG's single port — a meaningful difference when you want to simultaneously connect a USB drive and a device charger or peripheral. The Philips also includes a 3.5mm audio jack, which the LG omits entirely; this matters for users who want to plug in headphones directly for private listening without relying on Bluetooth. Additionally, the Philips features Bluetooth 5.2 compared to the LG's Bluetooth 5.0 — the newer version offers improved connection stability and more efficient handling of multiple simultaneous Bluetooth devices, such as a soundbar and wireless headphones at once.

The LG has no standout connectivity advantage in this group. The Philips edges ahead with a more practical physical port layout and a marginally newer Bluetooth implementation, making it the better-equipped option for users who value peripheral flexibility and direct audio output.

Both TVs share a near-identical audio foundation: stereo speakers, Dolby Atmos, Dolby Audio, Dolby Digital, Digital Out, and full HDMI ARC and eARC support. The presence of eARC on both is worth noting — it allows a connected soundbar or AV receiver to receive high-bandwidth audio formats over a single HDMI cable, which is the cleanest way to pass through lossless audio from streaming apps or external sources.

The one meaningful split between them is Dolby Digital Plus support, which the LG carries and the Philips does not. Dolby Digital Plus is an enhanced codec used prominently by streaming platforms — most notably Netflix and Disney+ — to deliver higher-quality compressed audio compared to standard Dolby Digital. Its absence on the Philips means that in certain streaming scenarios, audio may be downgraded to a lower-quality track rather than taking full advantage of what the service offers.

Neither TV includes a subwoofer or any advanced virtual surround processing beyond what Dolby's own suite provides, so the gap between them is narrow but real. The LG holds a modest advantage in this group solely due to its Dolby Digital Plus support, which is directly relevant for streaming-heavy users and requires no additional hardware to benefit from.

Footprint-wise, the two TVs are nearly interchangeable — widths of 1676 mm and 1669 mm respectively, and heights within 3mm of each other. For shelf or wall planning purposes, they occupy essentially the same horizontal space. Both support VESA mounting, so neither has an installation advantage on that front.

The divergence becomes significant when looking at depth and weight. The LG is just 50.8 mm thick compared to the Philips's 93 mm — nearly twice as deep. This is a direct consequence of the LG's Mini-LED backlighting assembly, which requires more internal hardware, yet the LG still manages to be the slimmer unit. For wall-mounting, the LG will sit noticeably closer to the wall, which is a real aesthetic advantage in living spaces where flush mounting matters. The LG's computed volume of roughly 82,200 cm³ versus the Philips's 150,250 cm³ further underscores how much more compact it is as a physical object.

Weight tells a different story, however. The LG comes in at 32,387 g (~32.4 kg) against the Philips's considerably lighter 23,070 g (~23.1 kg) — a difference of over 9 kg. That gap is highly relevant during installation: a heavier TV demands sturdier wall mounts, more careful handling, and ideally an extra pair of hands. For stand placement the weight is less critical, but for wall mounting it increases both hardware requirements and installation effort. Overall, the LG has the clear edge in profile and visual presence on a wall, while the Philips is meaningfully easier to physically handle and install.

Smart platform capabilities are well-matched across the board: both TVs ship with a built-in smart TV system, Google Assistant, Alexa, smartphone remote support, USB recording, voice commands, and standard utilities like a sleep timer and child lock. Neither supports Apple HomeKit or Siri, so users deep in the Apple ecosystem will find both equally limited on that front.

The clearest feature differentiator is AirPlay, which the LG supports and the Philips does not. For households with iPhones, iPads, or Macs, AirPlay enables seamless wireless screen mirroring and audio streaming without needing a third-party device — its absence on the Philips is a tangible gap for Apple users specifically. On the power consumption side, the contrast is stark: the LG draws 151W during operation versus the Philips's 80W — nearly half. Over hours of daily use, that difference compounds into a meaningful gap in electricity costs over the TV's lifespan, and it also reflects the higher power demands of the LG's Mini-LED backlighting hardware.

The LG holds the advantage in this group for Apple-ecosystem users due to AirPlay support, while the Philips has a notable edge in energy efficiency at 80W operating consumption. For users without Apple devices, the power draw gap becomes the more practically significant differentiator in day-to-day ownership.
