LG OLED C4 55 Inch outperforms on picture quality with perfect blacks and 120Hz motion per RTINGS and CNET, beating the QNED80 by wide margins in dark-room contrast. The QNED80 counters with higher brightness and lower burn-in risk for daytime sports, trailing the C4 by 2-3 points in most scores. This is not a close call as the OLED advantage is decisive for cinematic use.
