If you prioritize picture quality, especially for movies in a dark room, the LG G3 OLED is superior with better performance in dark scenes and wider viewing angles. However, the Samsung QN90A LCD will be less expensive and performs better in very bright rooms due to its higher brightness. The OLED technology of the LG may offer better gaming features and color accuracy, but can risk permanent burn-in with static images over time. The Samsung is more durable in this aspect. If cost is a major factor and you often watch TV in bright conditions, the Samsung may be a better fit. Give Feedback
