The LG B3 OLED presents superior picture quality and performs exceptionally well in dark rooms with its ability to display true blacks. It's also great for viewing angles and offers upscale voice command features. On the other hand, the Samsung Q70A LCD is a more budget-friendly option with decent picture quality but may not perform as well in dark environments due to its inability to produce the same deep blacks as OLED. It's better suited for bright rooms, as it can handle reflections well, but has narrower viewing angles and lacks voice command interaction. If you prioritize top-notch picture quality and can afford a higher price, go for the LG B3 OLED. However, if you're looking to save money and need a TV that performs well in a brighter room, the Samsung Q70A LCD could be adequate. Give Feedback

The LG B3 (OLED) is excellent for movies & TV, while the Samsung Q70A (LCD) is only fair.
The LG B3 OLED excels in movie watching due to its perfect blacks and infinite contrast ratio, thanks to its OLED technology which allows individual pixels to turn off completely, coupled with uniform black levels, wide viewing angles, and superior color performance right out of the box. However, the Samsung Q70A LCD, while offering good color accuracy, lacks local dimming and has a lower contrast ratio and black uniformity, leading to less impressive dark scene performance and more limited viewing angles, which diminishes the cinematic experience.
