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: Pick Samsung QN75Q80TAFXZA if you prioritize a lower price of $2,699.99 and need four HDMI ports without VRR; pick LG OLED77C3PUA if you value the larger 77‑inch OLED screen, infinite contrast, and VRR for gaming despite the higher $4,299.98 price. Both share 4K resolution, 120 Hz refresh, and HDR support, but LG wins on picture quality while Samsung wins on cost

Samsung QN75Q80TAFXZA lists at $56.68 while LG OLED77C3PUA lists at $173.45 — Samsung QN75Q80TAFXZA undercuts LG OLED77C3PUA by $116.77 (206%).

Winner: LG OLED77C3PUA
