In the vast realm of smart televisions, the TCL 6-Series 4K R646 emerges, not as a mere contender, but as a dazzling beacon of technological prowess. Its design? Modern. Its setup? A child’s play. Its visuals? A symphony for the eyes. Dive with us into this intricate tapestry of features, performance, and value, as we unravel the enigma that is the TCL 6-Series 4K R646.

Sleek and Modern Design

As soon as you open the box, the immediately catches your eye with its sleek and modern design. While it shares similarities with the Roku versions of TCL TVs, one unique feature stands out – a small bump-out covered in gray fabric, reminiscent of a Google Nest Mini speaker. This clever design element hints at the TV’s integration with Google Assistant, offering an always-listening feature for your convenience. However, if privacy is a concern, fear not! The TV includes a simple switch on the back to disable the built-in microphone.

Flexibility is a key aspect of the TCL 6-series Google TV. The 65-inch model we reviewed allows for the installation of feet at either the far ends or toward the center, providing different placement options to suit your preferences. Additionally, the feet offer improved cable management, allowing you to route thicker HDMI cables away from the back of the TV through a flexible flap. This ensures a clean and organized setup.

Seamless Setup Made Easy

Setting up the TCL 6-series Google TV is a breeze. Thanks to the Google Home app, the process becomes even simpler, eliminating the need for excessive button-mashing on the remote. From the moment I powered up the TV until the completion of the setup wizard, it took approximately 14 minutes. While the process may seem time-consuming, the convenience of using the Google Home app and its seamless with the TV makes it well worth the time investment.

It’s worth highlighting that the Google TV platform offers the option to opt-out and set up the TCL 6-series Google TV as a “dumb TV.” This serves as a refreshing alternative for those who prefer a minimalist smart TV experience without unnecessary features.

Stunning Visuals with Incredible Contrast and Black Levels

When it comes to the TCL 6-series Google TV, picture quality is where it truly excels. Irrespective of its price, this TV showcases stunning visuals that will leave you in awe. In fact, the TCL 6-series Google TV offers the best price-to-picture quality ratio I’ve encountered to date.

Compared to its Roku-based counterpart, the R635, the R646 boasts refinements that enhance its picture quality. TCL’s integration of a mini-LED backlight system and improved local-dimming algorithms result in better contrast, black levels, and peak brightness. Whether you’re watching Dolby Vision content on Netflix, HDR videos on YouTube, sports broadcasts, or playing video games, the TCL 6-series Google TV a fantastic visual experience.

The TV’s peak brightness in SDR mode measures approximately 850 nits, while in HDR mode, it reaches between 1,150 and 1,200 nits. These impressive measurements are on par with, if not surpass, some top-of-the-line TVs from leading brands. Moreover, the TCL 6-series Google TV showcases outstanding black-level performance, effectively mitigating halos around bright objects on black backgrounds. This ensures an immersive viewing experience, particularly during dark scenes in movies or shows.

Adequate Sound Quality for Everyday Use

When it comes to sound, built-in speakers rarely deliver the same audio experience as external audio systems. The TCL 6-Series is no exception, providing adequate sound quality for everyday use. However, for a truly immersive home theater experience, we recommend investing in external audio solutions that will enhance the audio output and surpass the limitations of built-in speakers. With the TCL 6-Series, you have the freedom to tailor your audio setup according to your preferences, ensuring a personalized and rich sound experience.

Ample Storage Space

One notable advantage that the TCL 6-Series offers over its competitors is ample storage space. With 24GB of built-in storage, four times the capacity of most Android TV/Google TV dongles, users no longer have to worry about running out of storage or compromising on their favorite apps. TCL understands the importance of pre-installed apps in elevating the overall user experience. With utilities such as IMDb TV, Pandora, and Sling TV readily available, users can seamlessly access a wide range of content with just a few clicks.

The TCL 6-Series TV excels in gaming performance, boasting HDMI 2.1 inputs along with features such as Variable Refresh Rate (VRR) and Auto Game Mode (ALLM), making it ideal for fluid and responsive gameplay.

Impressive Gaming Capabilities

Gaming enthusiasts will appreciate the TCL 6-Series TV’s gaming capabilities. With HDMI 2.1 inputs, and features like Variable Refresh Rate (VRR) and Auto Game Mode (ALLM), perfect for smooth and responsive gameplay. Whether you’re playing on a PlayStation 5, Xbox Series X, or Nintendo Switch, you can expect crisp visuals and an immersive gaming experience.

 A Few Bugs and Quirks, but Still a Standout Option

While the TCL 6-Series Google TV has undoubtedly improved since its initial release, there are still a few bugs and quirks that persist.

Occasionally, the TV may reset its picture settings to “low power” mode, requiring users to manually readjust the settings. This issue has been addressed in recent updates, but it’s worth noting. Another minor inconvenience is the default display of Dolby Vision content in “Dolby Vision IQ” mode, which introduces a slight soap opera effect. Although this can be rectified by adjusting the picture mode, it would be preferable to have more granular controls readily available. Additionally, some important features, such as VRR and auto low-latency mode, are buried deep in the settings menu, making them less accessible to users.

Despite these minor drawbacks, the overall performance and picture quality of the TCL 6-Series Google TV make it a standout option in its price range.

Panel Quality Can Vary, So Inspect Carefully Before Buying

It’s important to mention that LCD panel quality can vary, and the TCL 6-Series Google TV is no exception. While my review unit exhibited exceptional panel uniformity with minimal backlight bleed, some buyers have reported instances of the “dirty screen effect,” where patchy dark areas are visible on a uniform color display. This issue, known to occur across multiple TV brands, is a testament to the unpredictable nature of panel quality in LCD TVs. Therefore, it’s advisable for potential buyers to examine the display carefully before making a purchase.

Our Verdict

Ah, the TCL 6-Series Google TV! A veritable gem in the world of affordable luxury. Its strengths? As vast as the ocean. Its drawbacks? Mere ripples in its vast sea of capabilities. Seekers of cinematic ecstasy, look no further. Yet, a word to the wise: let your eyes be the final judge, for in the world of LCDs, not all panels are crafted equal.

The TCL 6-Series 4K R646: Who It’s For?

The TCL 55″ Class 6-Series 4K R646 is a great TV for anyone who wants great picture quality at an affordable price. It’s especially good for people who watch a lot of HDR content, as the TV’s HDR performance is excellent. The TV is also great for gamers, as it has low input lag and supports a variable refresh rate. However, the TV’s viewing angles are not as wide as some other TVs, so it’s not the best choice for people who watch a lot of TV from the sides. The sound quality is also not the best, so you may want to consider getting a soundbar if you’re serious about audio quality.
