TCL 6 Series QLED TV with Mini LED Reviews


The TCL6 series is often the most recommended model for TCL by mainstream TV buyers. In recent years, TCL has provided commendable performance and simple Roku TV software at a reasonable price. Coupled with the addition of Mini LED technology, it is relatively excellent in terms of video quality.

In terms of performance, the TCL 6 series is very similar to the full-array Samsung Q80T QLED TV and LG Nano 90, both of which use quantum dot variants to achieve higher color accuracy.

The new version of the TV TCL 6 series R646 released in 2021 has the same functions as the old one, but also has a better light control effect. Two HDMI 2.1 ports for 4K/120Hz games, the performance is not much different. But if the price is the same, you can choose the new model.


The TCL 6 series has many advantages in terms of design, but it is not exactly like a work of art like Samsung's The Frame. The 6-series R635 screen is relatively thick and heavy, and it does not reach the ultra-thin screen like OLED. But the almost borderless design is more pleasing. The legs of the TV can be combined and placed on a smaller table or stand, or connected to the outer corner of the TV to increase stability.

In terms of interfaces, there are Ethernet, four HDMI 2.0 ports, one supporting eARC, and one AV In port, which can receive standard composite (red-white-yellow RCA) input, USB and optical audio.

Smart function

TCL 6 series R635 uses Roku TV. TCL supports the screen projection function, which can project the mobile terminal information to the TV. If it is a party or meeting, users can take turns to play their video content and so on. At the same time, this function can also be used as a large-screen digital photo frame, which is very practical as a decoration.

The biggest improvement of the TCL 6 series lies in its performance, the most obvious changes are the black field, contrast and so on. This is due to the new Mini LED backlight system, which uses thousands of LEDs to achieve near-perfect black levels near bright highlights.

The 6 series is closer to OLED in terms of brightness and contrast, but has the advantage of using quantum dots. It can have a wider color gamut, and the TV display color is more abundant. In the test, we tried a lot of different content, from Earth Night (available in Dolby Vision) to local news, to show how the TV upgrade the HD content to fill the 4K screen.


The TCL 6 series still relies heavily on its AiPQ engine to convert HD content into 4K content. It uses three algorithms to achieve this, one for color, one for sharpness, and another for contrast. TCL contains five default picture settings, each of which can be further tested and refined in terms of color and contrast.

Another problem with the AiPQ engine is that regardless of the mode, the processor can over-process areas of extreme brightness to make them pure white.

For gamers, the 6 Series Mini LED is a bit like a double-edged sword. On the one hand, it supports 120Hz gaming and variable refresh rate. But on the other hand, at 120 fps, the resolution is limited to 1440p, and the TV does not support proprietary GPU technologies such as Nvidia G-Sync and AMD Freesync. Obviously, gameplay with 1440p/120fps is better than 1080p/60, but if TCL uses HDMI 2.1, it will be more perfect.


The sound of the TCL 6 series is completely acceptable. On the frame, there are two 8W speakers. Although there are fewer TV speakers that use 10W or even 20W drivers, such as the Sony X950H and other previously evaluated speakers, they are not inferior in the expression of treble and midrange.

If the sound quality is still not enough, you can also buy a sound bar than the panoramic sound to get better sound quality.


I got this tv for my in-laws for Christmas and I personally have a Sony OLED. This TCL could hang with my OLED tv easy for half the price. Very impressed and jealous of how bright it gets.
