Samsung QN75QN90AFXZA and LG OLED77C2PUA represent two distinct approaches to large-screen premium television performance according to aggregated public reviews and manufacturer specifications. The Samsung model relies on a Neo QLED backlight with Mini LED local dimming that delivers high peak brightness. And solid color volume, yet several key performance metrics such as exact contrast ratios and input lag figures remain only partially disclosed in official materials. In contrast, the LG OLED77C2PUA uses a confirmed WRGB OLED panel that consistently receives praise in reviews for its perfect blacks, wide viewing angles. And measured response times that support accurate motion handling and gaming features. Both sets include HDMI 2.1 ports and support for variable refresh rates, but the LG’s self-emissive technology removes the blooming artifacts sometimes noted with the Samsung’s backlight. Bottom line: choose the LG OLED77C2PUA when confirmed premium picture quality and fully published specifications matter most.

Verdict: Pick LG OLED77C2PUA if you need confirmed OLED picture quality, 120Hz refresh, and a known price. Pick Samsung QN75QN90AFXZA if you prefer to wait for official specifications before deciding. Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.

LG OLED77C2PUA lists at $5,499.99 while Samsung QN75QN90AFXZA lists at $1,799 — Samsung QN75QN90AFXZA undercuts LG OLED77C2PUA by $3,700.99 (206%).
