Samsung QN75Q80TAFXZA and LG OLED77C3PUA represent two distinct approaches to large-screen 4K televisions, one built around a backlit LCD panel with quantum-dot color and the other around self-emissive OLED pixels. The Samsung model delivers a 75-inch image with solid brightness, four full-bandwidth HDMI ports, and a more accessible price of $2,699.99, yet it lacks variable refresh rate support and cannot match the perfect black levels of its rival. The LG OLED77C3PUA offers a 77-inch screen with infinite contrast, true pixel-level dimming, and VRR compatibility that benefits console gaming, though it carries a higher cost of $4,299.99 and only three HDMI 2.1 ports. Public reviews and manufacturer specifications highlight the Samsung set’s value for bright-room viewing and the LG set’s cinematic depth in controlled lighting. Bottom line: choose the Samsung QN75Q80TAFXZA for lower price and port count or the LG OLED77C3PUA for screen size, contrast, and gaming features.

Verdict: If you prioritize absolute picture fidelity, deep blacks, and gaming performance, the LG OLED77C3PUA is the clear winner despite its higher cost. Both deliver 4K 120 Hz, but LG’s Dolby Vision and OLED contrast give it a superior visual experience.

LG OLED77C3PUA lists at $2,999 while Samsung QN75Q80TAFXZA lists at $1,799 — Samsung QN75Q80TAFXZA undercuts LG OLED77C3PUA by $1,200 (67%).
