Top 4K Roku Smart TVs for 2019


Our review process

With all the TVs on the market, choosing one can be difficult. Fortunately, we have extensively studied over 500 for you. From all these choices, we've laid out the benefits and drawbacks of 25. We've considered 23,000 data points, from brightness level to Bluetooth connectivity. The choices are seemingly countless but our advanced learning system can direct you along the way. Use this platform and become an informed customer before choosing your newest 4K Roku Smart TV.

Are you buying a new 4K Roku Smart TV? Here are some things you should know. 4K TVs have a wide color gamut and upconverting technology, which allows content with fewer pixels to fit higher-resolution displays. They deliver bold and sharp visuals, reducing detail distortion or blurring. With UHD dimming, they deliver darker blacks and lighter whites by precisely adjusting the screen's brightness. HDTVs provide a higher pixel count than standard-definition televisions to improve the image resolution.

These TVs incorporate voice recognition, letting you verbally initiate a number of specific functions, such as turning the set on and off, exploring channels, and adjusting the volume. They offer a variety of built-in games and include an app store. TVs with Roku have a smart remote, allowing you to easily manage all of the digital devices attached to your television. Designed with split-screen capabilities, they are capable of displaying different programs at the same time. They offer a universal search function, helping you locate content across different platforms or channels. However, these Roku TVs require an additional device, so you'll have one more component near your TV and another remote control on your coffee table. On the other hand, they have limited screen mirroring functionality, so you can't project some web browsers on your TV. However, they have limited program storage, so there's no library of your favorite shows to easily look through. Also, they require a learning curve, so it might take a while to get used to it.
