The TCL R646 generally costs a bit more than the TCL Q7 but offers better performance in bright rooms and marginally higher overall picture quality. However, the TCL Q7 is often somewhat less expensive and still has good picture quality, making it a more budget-friendly option. Both TVs have similar gaming features and support for Dolby Vision and HDR10+. If budget is a priority and you're satisfied with solid picture quality, the Q7 might suit your needs. If you can invest a little more for enhanced brightness, particularly beneficial for well-lit environments, the R646 may be the better choice. Give Feedback

The TCL R646 (LCD) is very good for cartoons & animation, while the TCL Q7 (LCD) is good.
The TCL R646 boasts a superior color performance out of the box, making it exceptionally suitable for vibrant animation, whereas the TCL Q7, while still good, falls slightly short in this area, potentially requiring additional calibration for optimal color accuracy. Considering both also have a good color gamut, the TCL R646's greater fidelity in reproducing a wide spectrum of colors renders it particularly appealing for cartoons that often utilize a rich and diverse palette.

The TCL R646 (LCD) is good for news, talk, & other TV, while the TCL Q7 (LCD) is only fair.
The TCL Q7 is rated lower than the TCL R646 for watching news and TV programs partly because the R646 has a superior SDR brightness, which is very important for day-to-day programming and a brighter display can enhance visibility in various lighting conditions. Additionally, the R646 is regarded as having better upscaling quality and a higher performance in color out of the box which is essential for vibrant and accurate images without manual adjustments, making it more suitable especially for non-technical users.

The TCL R646 (LCD) is very good for bright room, while the TCL Q7 (LCD) is good.
The TCL R646 performs better in a bright room because it has superior handling of reflections and offers higher brightness for HDR content than the TCL Q7, which ensures the picture remains clear and vibrant even in well-lit surroundings. While both TVs are good for bright rooms, the better reflection handling and higher HDR brightness of the R646 make it the preferred choice for environments with lots of ambient light.

The TCL R646 (LCD) and TCL Q7 (LCD) are both good for movies & TV.
The TCL Q7 excels in movie and cinematic TV watching due to its high black uniformity which translates to better dark scene performance, essential for viewing content with deep blacks, but has a lower contrast ratio than the R646. Conversely, the TCL R646 offers a slightly higher contrast and local dimming performance for more pronounced darks in high-contrast scenes, yet it has somewhat less effective black uniformity which may affect the viewing of uniform dark screens.

The TCL R646 (LCD) and TCL Q7 (LCD) are both only fair for sports.
The TCL Q7 and TCL R646 have similar performance issues when it comes to watching sports: both have less than ideal motion processing which can result in some blur during fast-moving scenes and their reflections handling is not optimal, leading to difficulties in well-lit environments. However, the TCL R646 gains a slight edge with better handling of reflections and a stronger response time, leading to less motion blur, but it still doesn't excel in this aspect.

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.
