The Samsung Q70A is typically much less expensive than the Sony A90J. If you're looking for a TV that offers good quality for gaming and watching news, talk shows, and reality TV, the Samsung Q70A could be a suitable option, especially if you're on a tighter budget. However, if you're willing to invest in a higher-end TV and are particularly interested in superb picture quality for watching movies and sports, the Sony A90J OLED would be an excellent choice. The OLED provides better performance in dark rooms, higher contrast, and wider viewing angles, which may justify the higher cost if these are priority features for you. The Samsung Q70A may not be as good in a very bright room due to its lower brightness and reflection scores. On the other hand, while the Sony A90J has a slightly lower bright room performance, it compensates with better handling of reflections and a better overall picture quality in various lighting conditions. Both TVs have a 120Hz refresh rate and support 4K at 120Hz, making them both suitable for modern gaming consoles. In conclusion, if cost is a concern and you want a solid all-around TV, go for the Samsung Q70A. If you're after the best picture quality and viewing experience, and are prepared to pay a premium, choose the Sony A90J OLED. Give Feedback

The Sony A90J (OLED) is excellent for movies & TV, while the Samsung Q70A (LCD) is only fair.
The Samsung Q70A, with its LCD screen, lacks the perfect contrast and black uniformity capabilities that the Sony A90J's OLED screen excels at, making the A90J superior for experiencing the deep blacks and high contrast essential for movies and cinematic TV. Additionally, Sony's A90J offers better viewing angles and more accurate colors out of the box, further enhancing cinematic viewing.

The Sony A90J (OLED) is excellent for sports, while the Samsung Q70A (LCD) is only fair.
The Sony A90J (OLED) excels at watching sports due to its outstanding motion processing and excellent reflections handling, which keep the image clear during fast action and in bright environments; in addition, its wide viewing angles ensure that the picture looks good from different seating positions. In comparison, the Samsung Q70A (LCD) performs fair in sports viewing as it has a slower response time and poorer reflections handling, with less impressive motion processing and narrower viewing angles, although it has decent gray uniformity, which is somewhat important for sports content.

The Sony A90J (OLED) is very good for gaming, while the Samsung Q70A (LCD) is good.
The Samsung Q70A has a superior input lag performance, making it more responsive in gaming situations, which is critical for fast-paced action, while the Sony A90J, although slightly behind in input lag, offers exceptional response time, meaning the screen transitions quickly without motion blur, enhancing gaming graphics. Both TVs have a 120Hz refresh rate, ensuring smooth gameplay, but the Q70A might be preferred by competitive gamers for its responsiveness, and the A90J by those who value image fluidity and visual detail.

The Sony A90J (OLED) is very good for news, talk, & other TV, while the Samsung Q70A (LCD) is good.
The Samsung Q70A has very good SDR brightness, making it suitable for watching news and TV programs in well-lit environments, but its upscaling quality is just good, which might not render lower-resolution content as finely as possible. The Sony A90J, on the other hand, boasts excellent upscaling and SDR brightness, offering a crisper image for varied content qualities and being highly capable in bright settings, while its OLED nature provides superior contrast and colors that enhance the viewing experience for daily programming.

In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."
