This significant price difference places the LG model in a more accessible range for consumers looking for high-quality OLED technology without breaking the bank. While the Samsung boasts a larger screen, the LG offers a compelling value proposition with advanced features at a fraction of the cost.
Display Quality
Both the LG and Samsung TVs offer exquisite display quality, each utilizing advanced technology to enhance viewing experiences. The LG C5 features OLED technology that delivers perfect black levels and vibrant colors, thanks to over 8.3 million self-lit pixels. This results in stunning images, even in bright rooms. On the other hand, the Samsung S90F employs its NQ4 AI Gen3 processor, which utilizes 128 neural networks to upscale content to 4K resolution, ensuring impressive detail and smooth picture quality. While both models excel in brightness and contrast, the LG's superior black levels might appeal more to cinema enthusiasts.
Sound Performance
Sound quality is a critical aspect of any home entertainment system, and here, both models shine. The LG C5 includes Dolby Atmos technology, providing an immersive sound experience that places viewers in the heart of the action. In contrast, the Samsung S90F features a 5.1.2 channel sound system, including side- and top-firing speakers and a subwoofer, delivering surround sound that envelops the listener. While the LG focuses on a cinematic audio experience, the Samsung's robust sound system may be more appealing for those who prioritize full-room audio immersion.

The inclusion of NVIDIA G-Sync and AMD FreeSync Premium further enhances the gaming experience.

While both televisions are optimized for gaming, the LG's lower response time may give it an edge for competitive gamers.

Its Art Gallery mode allows users to display artwork or photos when not in use, adding aesthetic value to the room. The Samsung S90F, with its larger 83-inch screen, is designed to be a statement piece but may require more wall space. While personal preference plays a significant role in design choice, the LG's versatility as both a TV and a decorative piece may appeal to a broader audience.
