The SAMSUNG 55-Inch Class Crystal UHD 4K DU7200 Series HDR Smart TV offers a well-rounded viewing experience with its impressive 4K resolution and HDR technology, which ensures vibrant colors and fine details. The PurColor feature enhances the color spectrum, providing more lifelike images. Motion Xcelerator reduces lag and blur, making it suitable for fast-paced content such as sports or action movies. However, the refresh rate is 60 Hz, which might not satisfy users looking for the smoother motion typically found in 120 Hz models, especially gamers or those watching high-speed action scenes.

The TV’s smart features, powered by the Tizen OS, offer a variety of apps and streaming services, making it easy to access your favorite content. The inclusion of Samsung TV Plus is a bonus for those who enjoy live streaming TV. Object Tracking Sound Lite adds virtual 3D surround sound for a more immersive audio experience, enhanced further when paired with a Samsung Q-series or S-series soundbar using Q-Symphony. Connectivity is versatile with Bluetooth, Wi-Fi, and HDMI options. The TV’s Crystal Processor 4K ensures that all content is upscaled to near-4K quality, which is a significant advantage for regular HD content.

One potential drawback is the TV's weight and dimensions, as it might require sturdy mounting or furniture. Weighing 31.1 pounds and measuring 9.3 x 48.6 x 29.8 inches, it’s relatively hefty. This TV is best suited for movie enthusiasts and general home entertainment, offering a solid mix of picture quality, smart features, and audio enhancements.

Buying Guide for the Best 4 K Tv 120 Hz

Choosing the right 4K TV can significantly enhance your viewing experience, whether you're watching movies, playing video games, or streaming your favorite shows. To make an informed decision, it's important to understand the key specifications that can impact the performance and suitability of the TV for your needs. Here are some essential specs to consider and how to navigate them.
ResolutionResolution refers to the number of pixels that make up the picture on the screen. A 4K TV has a resolution of 3840 x 2160 pixels, which is four times the number of pixels found in a Full HD TV. This higher resolution provides sharper and more detailed images, making it ideal for large screens and close viewing distances. If you enjoy watching high-definition content or playing video games with detailed graphics, a 4K resolution will enhance your experience.
Refresh RateThe refresh rate is the number of times per second that the TV updates the image on the screen, measured in Hertz (Hz). A 120 Hz refresh rate means the TV refreshes the image 120 times per second. This is important for reducing motion blur and providing smoother motion, especially in fast-paced content like sports, action movies, and video games. If you watch a lot of fast-moving content or are a gamer, a higher refresh rate like 120 Hz will provide a more fluid and enjoyable experience.
HDR (High Dynamic Range)HDR enhances the contrast and color range of the TV, making bright areas brighter and dark areas darker, while also displaying a wider range of colors. This results in more realistic and vibrant images. There are different HDR formats, such as HDR10, Dolby Vision, and HLG. If you want the best picture quality with vivid colors and deep contrasts, look for a TV that supports HDR.
Smart TV FeaturesSmart TVs come with built-in internet connectivity and apps, allowing you to stream content from services like Netflix, Hulu, and YouTube without needing an external device. Some smart TVs also offer voice control and integration with smart home devices. If you enjoy streaming content and want a seamless, all-in-one entertainment system, consider a TV with robust smart features.
ConnectivityConnectivity options, such as HDMI and USB ports, are important for connecting external devices like gaming consoles, Blu-ray players, and sound systems. More HDMI ports allow you to connect multiple devices simultaneously without constantly swapping cables. If you have several devices to connect, look for a TV with multiple HDMI ports and other connectivity options.
Screen SizeScreen size is measured diagonally from corner to corner and is a key factor in your viewing experience. Larger screens provide a more immersive experience, especially in larger rooms. However, the ideal screen size also depends on your viewing distance. As a general rule, for a 4K TV, you can sit closer to the screen without noticing pixelation. Choose a screen size that fits your room and viewing habits.
Panel TypeThe type of panel used in the TV affects the picture quality and viewing angles. Common panel types include LED, OLED, and QLED. LED panels are generally more affordable and offer good brightness, while OLED panels provide better contrast and deeper blacks. QLED panels, which use quantum dots, offer enhanced color accuracy and brightness. If you prioritize picture quality and viewing angles, consider an OLED or QLED panel.
