The TCL R648 is considered a premium LCD TV with miniLED backlighting that offers very good overall picture quality and gaming performance. However, when watching sports, you might find it only fair, possibly due to motion handling or color accuracy during fast-paced scenes. This TV performs well in dark rooms and even better in bright rooms, making it versatile for different lighting conditions. The contrast is high and the set has excellent SDR brightness, but local dimming and HDR brightness are just good, indicating that while it will provide a decent HDR experience, it might not be the best in its class. It has a very good reflections score, so glare should not be a major issue. The TCL R648 also provides very good sound quality with built-in great speakers and supports various HDR formats like Dolby Vision, which enhances viewing experiences for movies and series. Keep in mind that the viewing angles are limited, so it’s not the best choice for wide seating arrangements. It’s also equipped with 4 HDMI ports, ensuring connectivity for multiple devices.

Ratings by Category
Cartoons & Animaton:4.6
The TCL R648 is great for watching cartoons and animation because it displays colors vibrantly and accurately straight out of the box, making these visuals pop without the need for additional calibration. Its color gamut and volume are also rated good, ensuring a wide range of colors is represented with plenty of depth and nuance.
Gaming:4.5
PerfectRec’s gaming score measures a TV's performance when it comes to playing video games. It is based on several factors that can significantly impact the quality of the gaming experience, including screen response time, input lag, and refresh rate. Screen response time is a critical factor that determines how quickly the TV can transition from one color to the next, while input lag measures the delay between the gaming console output and the TV display. Refresh rate refers to the number of times per second that the TV displays a new frame, which can impact the smoothness of the gaming experience. The gaming score also takes into account two other features: local dimming in gaming mode, which can enhance contrast and picture quality, and black frame insertion, which can reduce screen brightness and create a smoother gaming experience.
Bright Room:4.5
PerfectRec’s bright room score is a proprietary score of a television's performance in a bright environment, taking into account the following factors: screen brightness, reflections, and color volume. A higher score indicates better TV performance in bright conditions, minimizing glare and producing a more pleasant viewing experience.
Brightness is crucial in how well the image displays in direct sunlight, and low reflections reduce glare. Color volume contributes to color vibrancy and depth, which are vital in a bright environment.
Movies & TV shows:4.3
The TCL R648 is favored for movies and cinematic TV due to its excellent contrast and effective local dimming, which enhance deep blacks and overall picture depth, while its black uniformity ensures consistent dark scenes. Although its viewing angles are limited, this won't impact straight-on viewing, which is typical for movie watching, and its outstanding colors out of the box provide a rich and vibrant image without the need for immediate calibration.
Overall Picture:4.3
PerfectRec developed this proprietary score designed to provide an overall assessment of a display's visual performance. It is a comprehensive metric that takes into account many quantitative measures of picture quality, including: contrast ratio, color gamut, color volume, color accuracy, local dimming, gray uniformity, black uniformity, viewing angle, reflections (glare) and color calibration. By combining multiple factors, this score offers a more nuanced and comprehensive evaluation of a display's capabilities than a single factor.
News, Talk & Reality TV:4.2
The TCL R648 is ideal for watching news and TV programs due to its excellent performance in upscaling lower-resolution content and producing bright, clear images in standard dynamic range, ensuring that even non-HD broadcasts look good. Additionally, its strong initial color accuracy means that content will appear vibrant and true to life straight out of the box.
Sports:3.6
The TCL R648 has a motion processing capability that is less suitable for fast-paced sports, leading to potential blurriness during quick movements. However, this TV has very good response time and handles reflections well, making it a good fit for well-lit rooms and fast action scenes.
