The LG QNED80 is a 65-inch 4K display built for viewers who want refined picture quality and smart features. It combines QNED technology with edge-LED local dimming to deliver strong contrast and color performance in a slim, modern design.
This TV excels at AI-powered upscaling through its α5 AI Processor Gen7, which enhances lower-resolution content automatically. The 178° IPS viewing angles mean the picture stays vibrant even when you sit off to the side, making it ideal for family rooms and open living spaces.
Real-world performance shines during movies and streaming content, where the processing engine smooths out details and boosts clarity. The Magic Remote and webOS ecosystem make navigation intuitive, and the slim profile fits seamlessly into any entertainment setup.
The LG QNED80 suits movie enthusiasts, casual viewers, and design-conscious buyers who prioritize picture refinement over gaming specs. It performs well with standard content but lacks the gaming-specific features of more performance-driven models.
Pros
- Advanced AI upscaling makes older content look sharper and more detailed
- Superior IPS viewing angles keep colors consistent from any seat
- Slim design and Magic Remote create a polished, modern aesthetic
- Solid brightness (350 cd/m²) handles bright rooms without glare issues
Cons
- Edge-lit dimming produces less precise contrast control than full-array systems
- Lower native contrast ratio compared to full-array competitors
- Limited gaming specs; no HDMI 2.1 or high refresh rate support for console gamers
Head to Head: Key Differences
The TCL Q77K and LG QNED80 serve different viewing priorities. The TCL targets gamers with raw performance specs, while the LG focuses on picture refinement and everyday content consumption.
Display technology differs significantly. The TCL Q77K uses full-array local dimming, which delivers deeper blacks and better contrast control. The LG QNED80 relies on edge-lit dimming, a trade-off that keeps the TV thinner but limits shadow detail.
Gaming performance heavily favors the TCL. With 144Hz at 4K and 10–13ms input lag, the TCL Q77K crushes competitive gaming and sports viewing. The LG QNED80 lacks gaming-specific specs and sits at standard 60Hz refresh rates.
AI processing gives the LG an edge for everyday viewing. The α5 AI Processor Gen7 upscales lower-resolution content smoothly, making streaming and older movies look sharper. The TCL Q77K handles content well but lacks this specialized processing layer.
Viewing angles tell another story. The LG QNED80 uses IPS technology with 178-degree viewing angles, so colors stay consistent from any seat. The TCL Q77K offers decent angles but doesn’t match IPS performance.
Size and design differ too. The TCL Q77K spans 55 to 98 inches, giving you flexibility for different rooms. The LG QNED80 comes primarily at 65 inches with a slim, refined aesthetic that suits modern living spaces.
Motion handling shows mixed results. The TCL Q77K excels at high refresh rates, though some users report motion blur at 60Hz playback. The LG QNED80 handles standard frame rates smoothly thanks to its processing engine.
Choose the TCL for gaming and performance. Pick the LG for movies, design, and AI-powered picture enhancement.
Which One Should You Buy
The TCL Q77K takes the win in this matchup. It brings full-array local dimming, higher refresh rates, and lower input lag to the table.
This combination makes it a more versatile performer overall. Gamers and picture quality enthusiasts will notice the difference right away.
The LG QNED80 still holds its own, though. It shines in areas like viewing angles and upscaling finesse.
Best for each buyer
- TCL Q77K: Best for gamers and users who want high refresh rates, low input lag, and strong contrast through full-array local dimming.
- LG QNED80: Best for viewers who prioritize wide viewing angles, refined AI upscaling, and a sleek design for general and cinematic viewing.
