The price difference of about $1,926 means the LG model is approximately 53% cheaper. This substantial cost gap invites a closer examination of the features each TV offers.
Picture Quality
Both the LG and Samsung models boast impressive picture quality, but they achieve it through different technologies. The LG OLED excels with its Perfect Black and Perfect Color technology, utilizing over 8.3 million self-lit pixels for stunning visuals. It features Dolby Vision and HDR10, enhancing color and contrast for a cinematic experience. In contrast, the Samsung OLED employs its advanced 4K AI processor, leveraging 128 neural networks to upscale everything to 4K resolution. While both TVs promise excellent picture quality, LG's emphasis on OLED technology for deeper blacks contrasts with Samsung's focus on brightness and AI-driven enhancements.
Sound Performance
When it comes to sound, the LG OLED incorporates Dolby Atmos technology, delivering immersive audio that complements its stunning visuals. The audio experience is enhanced further by the LG model's AI Super Upscaling technology, which adjusts sound based on the content. On the other hand, the Samsung OLED also features Dolby Atmos, but it stands out with its Q-Symphony technology, allowing for synchronized audio output when paired with Samsung soundbars. This means that while both TVs provide high-quality sound, Samsung offers a more integrated audio system for those who invest in additional sound equipment.
Smart Features
The LG OLED is powered by the latest webOS 25 platform, which allows for seamless streaming and easy navigation across various applications. It includes built-in Alexa for voice control, enhancing the user experience. Samsung's OLED also offers smart features but focuses more on customizable design elements, allowing users to swap bezels to match their decor. Additionally, the Samsung model's Music Frame feature adds a unique aesthetic touch, transforming the TV into a piece of art when not in use. While both TVs provide smart capabilities, LG's focus on content accessibility may appeal more to dedicated streamers.
Gaming Capabilities
For gamers, the LG OLED C5 is engineered with impressive specifications, including a 0.1ms response time and a native 120Hz refresh rate. This model supports VRR up to 144Hz, making it ideal for fast-paced gaming without motion blur. The Samsung OLED also offers robust gaming features, supporting VRR at up to 4K 144Hz and including an advanced AI processor that smooths motion during gameplay. Both TVs cater to gamers, but LG’s specifications suggest a slight edge in minimizing lag and enhancing responsiveness.
Design and Aesthetics
In terms of design, the LG OLED features a nearly invisible bezel, allowing it to blend seamlessly into any room while also serving as a statement piece with its Art Gallery mode. The Samsung OLED, with its customizable bezel, gives users the flexibility to personalize their TV's appearance to fit their décor. While both models are aesthetically pleasing, the choice may boil down to whether you prefer a more integrated look with the LG or a customizable approach with the Samsung.
Price Comparison
The price difference between the two models is substantial, with the LG OLED retailing at $1,699.99 and the Samsung OLED priced at $3,625.98. This makes the Samsung model about 114% more expensive than the LG. While price is a significant factor, it’s essential to assess whether the additional features of the Samsung justify this premium for your specific needs.
Customer Reception
The LG OLED holds a sales rank of 603, indicating a strong market presence and customer satisfaction. Meanwhile, the Samsung OLED has a higher sales rank of 3,377, suggesting it is less popular among consumers compared to the LG. While both products have their strengths, the LG's higher sales rank could imply better overall customer reception, potentially indicating more trust in its performance and value.

Choosing between the LG 77-Inch Class OLED and the Samsung 83-Inch Class OLED ultimately depends on your priorities. If you seek an exceptional value with stunning picture quality and sound, the LG OLED is a fantastic choice at about $1,699.99.
