The LG G3 OLED TV offers superior overall picture quality, especially for movies, with perfect blacks and wide viewing angles, making it a better choice for dark rooms or a cinematic experience. Its gaming performance is excellent with quick response times, which is ideal for gaming enthusiasts. However, it costs more than the Samsung QN90C. On the other hand, the Samsung QN90C LCD TV is less expensive and performs better in bright rooms, due to its higher brightness levels. It has great sound quality and is suited for watching news and sports. However, its picture quality is not as high as the LG G3 OLED, particularly in dark rooms, and viewing angles are more limited. If budget is a concern and you watch TV mostly in a well-lit environment, the Samsung QN90C may be the better option. Give Feedback
