Verified Confidence: 88%

The LG OLED77C2PUA 77-inch OLED TV and the Samsung QN75Q80TAFXZA 75-inch QLED TV represent two distinct approaches to large-screen 4K viewing drawn from aggregated public reviews and manufacturer specifications. The LG model relies on self-emissive pixels that deliver perfect blacks and infinite contrast while running the responsive webOS platform with broad app support. In comparison, the Samsung set uses a full-array local dimming backlight on its VA panel to achieve stronger brightness suitable for well-lit spaces, along with a more affordable price point and Tizen operating system. Both televisions support 4K resolution and smart features yet lack detailed published figures on peak brightness and HDMI 2.1 implementation in early coverage. Bottom line: choose the LG OLED77C2PUA for deep contrast and ecosystem preference or the Samsung QN75Q80TAFXZA when balancing cost and performance in brighter environments.

Verdict: The LG OLED77C2PUA is the superior choice for picture quality, offering true blacks and infinite contrast that the Samsung QN75Q80TAFXZA cannot match. The LG OLED C2 wins on performance and quality, while the Samsung Q80T wins on value and longevity.
