Samsung QN75Q70TAFXZA and LG OLED77C3PUA represent two distinct approaches to large-screen 4K viewing in the current lineup. The Samsung QN75Q70TAFXZA is a 75-inch QLED model that relies on an edge-lit backlight. And quantum-dot color technology to deliver strong peak brightness around 700 nits, solid color volume, and a more accessible price point near $1,999.99. In contrast, the LG OLED77C3PUA uses a 77-inch self-emissive OLED panel to achieve perfect blacks, infinite contrast. And more convincing HDR highlights drawn from public review measurements and manufacturer specifications. Both sets run their respective smart platforms with responsive interfaces. And wide streaming app support, yet they diverge sharply on motion handling and connectivity: the LG includes four full-bandwidth HDMI 2.1 ports with variable refresh rate and 120 Hz support, while the Samsung offers more limited gaming features. The short version: choose the Samsung QN75Q70TAFXZA for brighter rooms on a tighter budget or the LG OLED77C3PUA when superior contrast and modern gaming features matter more.

Verdict: LG OLED77C3PUA wins on pure picture quality thanks to true blacks and Dolby Vision, making it the top pick for cinephiles. Samsung QN75Q70TAFXZA offers higher brightness and a lower price, so it’s better for bright rooms and tighter budgets. Choose LG if you prioritize contrast and HDR depth; choose Samsung if you need brightness and cost savings.

Winner: LG OLED77C3PUA

LG OLED77C3PUA: 7.5/10

Samsung QN75Q70TAFXZA: 6.5/10
