The Hisense U8K is typically much less expensive than the TCL R648. However, if you're willing to invest in a slightly higher-quality viewing experience, particularly for sports and cartoons, and if a wider array of supported HDR formats, including Dolby Vision and HLG, is important to you, the TCL R648 may be worth the extra cost. Additionally, the TCL R648's premium build quality may appeal to those who prioritize construction and design aesthetics. Give Feedback

The Hisense U8K (LCD) is very good for movies & TV, while the TCL R648 (LCD) is good.
The Hisense U8K provides excellent contrast, local dimming, and black uniformity, which are key for a superior movie-watching experience especially in dark scenes, while the TCL R648 offers good performance in these areas but doesn't match the Hisense in black reproduction. Both TVs have good color accuracy and volume out of the box, with Hisense having an edge, and while both have limited viewing angles typical for VA panels, issues such as gray uniformity are similarly decent on both, not affecting the cinematic experience significantly.

The Hisense U8K surpasses the TCL R648 in SDR and HDR brightness, making it more suitable for bright rooms by providing a clearer picture in well-lit environments. Both TVs handle reflections very well, but the Hisense's higher brightness capabilities give it a slight edge for maintaining picture quality where ambient light is present.

The TCL R648 (LCD) and Hisense U8K (LCD) are both only fair for sports.
Both the Hisense U8K and the TCL R648 have their strengths for watching sports, but there are differences to consider. The Hisense U8K has a "fair" response time and very good reflections handling, which is useful, but it lags behind in motion processing and has a narrow viewing angle, which could affect the clarity of fast-moving objects and limit off-center viewing; whereas the TCL R648 has a "very good" response time, lending to less motion blur during fast action, a similar narrow viewing angle, but it struggles more with reflections which could be distracting in a bright room.

Although they have very similar scores, PerfectRec considers Hisense U8K (LCD) to be excellent for cartoons & animation, while the TCL R648 (LCD) is very good.
The Hisense U8K excels in watching cartoons and animation due to its very good color accuracy out of the box and very good color gamut, ensuring vibrant and consistent colors. In contrast, the TCL R648 displays colors excellently out of the box and has a good color gamut, which is still commendable for animated content but not as expansive as the Hisense U8K in color range.

About Hisense
Hisense, a Chinese TV manufacturer, entered the US market in approximately 2011 and has since acquired TV divisions from various companies such as Toshiba, Sharp, Hitachi, and NEC. Currently ranking as the fourth largest vendor in terms of sales volume, Hisense aims to capture a wide range of TV budget segments. They offer exceptional value with TVs that often outperform their competitors at similar price points, making them a compelling choice for consumers. In the US, they use Google TV as their smart TV software which provides the largest app selection and a very modern user interface, however it is not as user friendly as the software from other vendors.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
