Samsung QN90B QLED vs. LG C3: What’s the Difference?

Are you attempting to pick between the LG C3 and the Samsung QN90B QLED? Although these televisions may appear similar at first glance, there are actually a number of distinctions between the two that should influence your decision. In this article, we’ll compare the features, pros, and cons of the Samsung QN90B QLED and the LG C3 in detail.


There are some obvious distinctions between the LG C3 and the Samsung QN90B QLED’s designs that merit discussion. The Samsung QN90B QLED offers a streamlined and thin shape, as well as a simple design that highlights its screen. Its extremely narrow bezel gives the TV a nearly borderless appearance, enabling an immersive viewing experience. The QN90B QLED’s stand is also well made, with a basic yet solid build that increases the TV’s overall stability.

The LG C3, in contrast, has a more standard appearance with a broader bezel and a larger stand. The C3 does, however, have its own distinctive style, with a sleek metallic finish that gives it a modern and stylish appearance. The C3’s stand is also exceptionally strong, giving the TV a stable base.

Although each TV has distinct design advantages and disadvantages, the choice ultimately boils down to preference. While some people might favor the LG C3’s more traditional yet elegant appearance, others might favor the Samsung QN90B QLED’s sleek and minimalistic design.

Viewing angles

The LG C3 and the Samsung QN90B QLED differ significantly from one another in terms of viewing angles. Wider viewing angles are possible with the QN90B QLED thanks to a feature dubbed Ultra Viewing Angle that doesn’t result in any noticeable image quality degradation. Because of this, it is ideal for large spaces or for families who enjoy watching TV together from different angles. The LG C3, on the other hand, has a somewhat smaller viewing angle, which means that if you’re viewing it from a position that is too far to the side, the picture quality may suffer.

Despite this, both the LG C3 and the Samsung QN90B QLED provide exceptional picture quality with rich colors and deep blacks for an immersive viewing experience. The decision between the two ultimately boils down to personal preference and the particular requirements for your home. The Samsung QN90B QLED might be a better option for you if you enjoy watching TV from various angles or frequently have company over. On the other hand, if you’re someone who typically watches TV alone or from just one viewpoint, the LG C3 might be ideal for your requirements. Whichever you decide, both TVs have their strong points that you should consider before making a choice.

Processing power

Both the Samsung QN90B QLED and the LG C3 have powerful processors that can handle even the most demanding content in terms of processing power. Samsung has a special technology called the Quantum Processor 4K. This technology uses artificial intelligence to make the pictures on the QN90B QLED TV look better. It does this by making the pictures clearer and more detailed, which makes a more immersive viewing experience. With this technology, you can enjoy a more exciting and realistic viewing experience. Those who frequently switch between apps or use their TV for gaming may benefit from this processor’s quicker load speeds and smoother navigation.

Similar to how the Alpha 9 Gen 4 AI Processor used AI to enhance the picture and sound quality, the LG C3 likewise uses the same technology. It boasts features like low input lag and support for high frame rates that provide for a more responsive and engaging gaming experience. This processor is especially well-suited for gaming.

Although the CPUs in both TVs are formidable, it’s important to note that the Samsung QN90B QLED has a tiny advantage in terms of overall processing speed and performance. This is partly attributable to the sophisticated AI algorithms of the Quantum Processor 4K, which enable quicker load times and smoother navigation. Nonetheless, even the most demanding content can be handled with ease by both the QN90B QLED and the LG C3, both of which offer exceptional performance. Overall, you can be sure that whichever TV you choose between the LG C3 and the Samsung QN90B QLED will have excellent processing capabilities.

Samsung QN90B QLED and LG C3: Technology Updates

No significant technological overhauls have been observed in the Samsung QN90B QLED and LG C3 TVs of late. However, both manufacturers, Samsung and LG, have introduced firmware updates to their respective TV models, addressing minor issues.

In May 2023, the Samsung QN90B underwent a firmware update that enhanced the TV’s local dimming capabilities and resolved a flickering bug. This enhancement was achieved by augmenting the number of independently dimmable zones, resulting in a more consistent image quality with reduced blooming. The flickering issue was remedied by optimizing the local dimming algorithm, leading to a smoother and flicker-free viewing experience.

Similarly, in June 2023, the LG C3 received a firmware update that ameliorated color accuracy and rectified a bug causing a green tint in HDR content. The color accuracy was fine-tuned through calibration of the TV’s color settings, delivering colors that closely aligned with the original content’s intended hues. The eradication of the green tint was realized by updating the TV’s HDR algorithm, resulting in a precise and accurate image display without any tint-related anomalies.

In tandem with the firmware updates, both Samsung and LG have introduced novel features to their TVs through software updates. The Samsung QN90B now accommodates the Filmmaker Mode setting, aimed at providing an authentic viewing experience for movies and TV shows. On the other hand, the LG C3 now supports AMD FreeSync Premium Pro technology, mitigating screen tearing and stuttering during gaming sessions.

To summarize, although substantial technological advancements have been absent from the Samsung QN90B QLED and LG C3 TVs since February 2023, the manufacturers have undertaken firmware updates and introduced new features, culminating in improved performance and functionality for these television models.
