If you prioritize brighter room performance and wider viewing angles, consider the Samsung Q80B LCD as it performs better than the Samsung Q70A LCD in these aspects. The Q80B's Full Array Local Dimming (FALD) feature enhances contrast, providing a benefit for viewing movies and playing games in dark rooms. However, if you primarily watch sports, the Q70A might be a better fit as it handles motion slightly better. Both TVs are suitable for gaming with similar input lag and support 4K at 120Hz, so gaming performance will be comparable. Ultimately, your choice should be guided by the lighting conditions of your room and the content you watch most frequently. Give Feedback

The Samsung Q70A (LCD) is very good for cartoons & animation, while the Samsung Q80B (LCD) is good.
The Samsung Q70A is particularly adept at displaying cartoons and animation due to its superior colors out of the box, ensuring vibrant and accurate hues immediately after setup; additionally, it boasts a strong color gamut, which allows it to produce a wider range of colors. Conversely, the Samsung Q80B also provides good performance in this area but does not match the Q70A's immediate color accuracy or the extent of its color gamut, which is essential for animated content that often features bright and varied colors.

The Samsung Q80B (LCD) and Samsung Q70A (LCD) are both only fair for movies & TV.
The Samsung Q70A offers better contrast and black uniformity, which are crucial for deep blacks in dark scenes, making it a strong choice if these aspects are a priority for a good movie experience. However, the Samsung Q80B, with better viewing angles and a somewhat improved gray uniformity, would be more suitable for rooms where viewers are seated at various angles to the TV, although it compromises on contrast and black levels when compared to the Q70A.

The Samsung Q80B (LCD) and Samsung Q70A (LCD) are both only fair for sports.
The Samsung Q70A has stronger contrast which is key for sports but suffers from poor reflection handling and a narrow viewing angle which can be limiting for group viewing. On the other hand, the Q80B has better reflection handling and a wider viewing angle, making it more suitable for larger groups or well-lit rooms, while maintaining the same level of motion processing and response time as the Q70A.

Although they have very similar scores, PerfectRec considers Samsung Q80B (LCD) to be very good for gaming, while the Samsung Q70A (LCD) is good.
The Samsung Q70A is appreciated for gaming because it offers a very good response time and the best input lag, essential for fast-paced gameplay, whereas the Samsung Q80B, while also having the best input lag, couples that with a wider viewing angle, making it more versatile for multiplayer gaming situations.

Tom's guide
Matthew Murray | February 2023
"For most people its picture, sound, and price make it a midrange TV worth considering. HDR brightness was generally exceptional. Its viewing angles are shockingly good, among the very best we’ve seen recently from any non-OLED TV. For gamers input lag isn’t too shabby."
