Dimension comparison
Design and build quality
Both the Roku Smart TV 50-Inch Select and the 55-Inch Select share a similar aesthetic philosophy focused on simplicity and functionality. The primary physical distinction lies in the screen dimensions, with the 55-inch model offering a larger footprint suitable for wider living room setups. The 50-inch variant is designed for spaces where a compact profile is preferred, such as bedrooms or smaller apartments. Build materials are consistent across the Select series, prioritizing a lightweight flat screen design that facilitates easy wall mounting or stand placement. The bezel design is minimal to maximize the viewing area relative to the overall chassis size.
Display and Picture Quality
At the core of both televisions is a 4K flat screen panel designed to deliver sharp detail. The resolution ensures that content looks crisp, whether streaming high-definition movies or watching broadcast television. The 50-inch model provides a pixel density appropriate for its size, while the 55-inch model maintains the same 4K resolution across a larger surface area. Both units utilize Roku Smart Picture technology, which actively cleans up incoming TV signals and optimizes them for the best possible output. This feature automatically chooses the right picture mode based on the content being viewed, reducing the need for manual calibration by the user.
HDR and Color Performance
High Dynamic Range support is standardized on both units with HDR10 compatibility. This ensures that colors pop off the screen with lifelike clarity and that contrast levels are maintained during bright and dark scenes. The HDR10 standard allows for a wider range of brightness and color compared to standard dynamic range displays. Since both models utilize the same HDR10 specification, there is no significant difference in color performance or peak brightness capabilities between the 50-inch and 55-inch versions. Viewers can expect rich detail and consistent color reproduction across both screen sizes.
Smart Platform and Interface
The Roku operating system serves as the central hub for both televisions, providing a unified user experience. The home screen is customizable, allowing users to move apps around to prioritize their favorite streaming services. Both models grant access to over 500 TV channels, encompassing live in-season shows, hit movies, weather updates, and local news. The interface is designed to get users to what they want to watch fast, with a layout that emphasizes content discovery. There is no differentiation in the software interface between the two sizes, ensuring consistency in navigation and app availability.
Connectivity and Voice Control
A notable difference appears in the documented connectivity features regarding voice control. The 55-Inch Select explicitly lists compatibility with Roku Voice, Siri, Alexa, and Google Assistant, offering four distinct methods for hands-free operation. The 50-inch model documentation does not specify voice assistant compatibility in the provided data, though it shares the same smart platform. Additionally, the 55-inch model highlights the ability to effortlessly share videos, photos, and music, a feature not explicitly detailed for the 50-inch version. This suggests a potentially broader integration with smart home ecosystems for the larger model.
Software and Updates
Long-term usability is supported through automatic software updates on both devices. This ensures that users receive the newest apps and features without manual intervention. The system is designed to keep getting better over time, maintaining security and performance standards. Because both TVs run the same Roku OS, the update schedule and feature rollout should be identical. This parity ensures that neither model becomes obsolete faster than the other from a software perspective, protecting the investment regardless of the screen size chosen.
Price and Value
The 50-Inch Select is priced at $229.99, while the 55-Inch Select retails for $268.00. When calculating value based on screen real estate, the 50-inch model offers a lower cost per inch of display area. For budget-conscious buyers, the smaller model provides the same core 4K HDR10 experience at a more accessible entry point. However, the price difference of approximately $38 may be justified for users who prioritize the immersive quality of a larger 55-inch screen. Both units position themselves as offering a ton of entertainment at the best price, leveraging the free Roku channel ecosystem to offset hardware costs.
Which one should you buy?
Choosing between these two models depends primarily on room size and budget constraints. If you need a television for a smaller room or want to maximize value per inch, the 50-Inch Select is the logical choice at $229.99. It delivers the same picture quality and smart features as its larger counterpart. However, if you have the space and desire explicit confirmation of voice assistant compatibility and media sharing features, the 55-Inch Select is the superior option. Its larger 55-inch screen provides a more cinematic experience, making it the winner for most living room setups despite the higher price tag.
