There are a few key differences to consider when comparing the Samsung Q70C and Q80C QLED TVs. The Q80C outperforms the Q70C in image contrast and black levels thanks to its more powerful processor and Direct Full Array system. It also offers an enhanced audio experience with Dolby Atmos support and a higher 40W sound output.
The two models differ slightly in their design and other aspects. The Q70C has an AirSlim design, while the Q80C features a simple chamfered design. Additionally, the Q70C is 0.8 inches thinner compared to its competitor.
Considering the average price difference of $300, it’s important to evaluate the benefits against the additional cost. If you prioritize better display quality and enhanced audio performance, the Q80C may be worth the additional investment. However, if you are more budget-conscious and the slight differences in image and audio are not your top priority, the Q70C offers an excellent option at a more affordable price.
Picture quality in Samsung Q80C vs Q70C
The Samsung Q70C and Q80C both offer impressive video quality, but the Q80C has some notable enhancements. It features Direct Full Array technology, which provides more precise control over backlighting for deeper blacks and brighter highlights. Additionally, the Q80C supports Quantum HDR+, a more advanced HDR technology that optimizes picture quality in real time for more accurate and detailed HDR performance.
The Q80C is equipped with the Neural Quantum Processor 4K, a powerful processor that enhances video processing. It can upscale lower-resolution content with greater precision, resulting in clearer details and improved color accuracy. The Q70C, on the other hand, utilizes the Quantum Processor 4K, which still delivers impressive upscaling capabilities but with slightly fewer advanced features.
In tests, we can see that the Samsung Q80C outperforms the Q70C in terms of contrast. The picture has deeper colors and looks nicer.
When comparing dark images, I noted that the Q80C exhibited slightly better black reproduction. The Q80C’s Direct Full Array backlighting system and enhanced local dimming capabilities contributed to deeper blacks and increased detail in dark scenes.
The increased contrast adds an extra level of immersion and visual depth to the overall viewing experience.
