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.

The Hisense U8H excels at displaying cartoons and animation because it offers very good colors straight out of the box, meaning minimal tweaking is needed for vibrant and accurate depiction of animated content. Additionally, its excellent color volume ensures full and varied colors, which enhances the vivid and dynamic look that is often essential in animated material.

The Hisense U8H excels in SDR brightness, ensuring clear visibility for news and daytime TV shows, even in well-lit rooms. Its colors appear very good right out of the box, providing vibrant and accurate hues for a wide range of content without needing much adjustment.

The Hisense U8H is excellent for watching movies and cinematic TV due to its very good local dimming and high contrast ratio, which create deep blacks and help maintain detail in darker scenes. Additionally, it has good black uniformity, ensuring consistent shades across the screen, which is particularly noticeable when viewing in a dark room.

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.

The Hisense U8H delivers very good picture quality thanks to its excellent contrast with a high score and local dimming capabilities that enhance dark scene performance. Its HDR brightness is rated as excellent, providing vivid highlights for HDR content, while the TV's color reproduction is well-reviewed right out of the box, offering a very good color gamut and excellent color volume for a rich and varied palette.

The Hisense U8H has a very good response time, which is crucial for smooth motion during fast-paced sports, but its viewing angles are limited, meaning the picture quality drops when viewed from the side, which can be a disadvantage if you often watch with a large group spread out across the room. While it handles reflections very well, ensuring minimal distraction from light sources during the game, its gray uniformity is only fair, which might be noticeable during panning shots on the field.
