TCL R646 / 6 Series – A reasonable price and still all the important features?

Published 10/28/21
Update 12/01/21

TCL is known for their cheap and yet generally good TVs, and they want to prove that once again with the R646 6 Series.

It is the successor to last year’s TCL 6 Series R635, and instead of the Roku OS, the R646 is a Google TV. Coupled with the brand name QLED Mini LED, a great peak brightness and a contrast ratio that is unrivaled apart from OLEDs, many are curious what you get for your money with this TV.

The TCL R646 6 Series - Plain Desing

The R646 honestly looks similar to many other flatscreens. Not bad, but definitely not special either. The feet support the TV well, but they take up a lot of space in the front and back, which is why you should check in advance whether there is enough space or whether you want to mount it on the wall.

If you decide to mount it on the wall, you can hang the TV on the wall with the matching VESA wall mount. In this case, it stands a bit away from the wall, since the lower part of the TV is quite bulky due to the included hardware.

High contrast and with it a good brightness!

The R646 has a Direct LED backlight with full array local dimming and a 120Hz 10-bit VA-type LCD panel.

In terms of picture quality, the R646 surprised us by having an amazing contrast ratio, which is increased to almost 20000:1 by the Full Array Local Dimming. As a result, blacks are extremely dark and those who generally don’t want an OLED TV will get as close as they can with this TV.

With a peak brightness of 1200Nits, the TV also gets very bright and thanks to the mini LED backlight, it can be controlled more efficiently and more precisely, which makes for a really juicy HDR picture. You can clearly see the difference between SDR and HDR here, and thanks to HLG, HDR10+ and Dolby Vision, all relevant formats are included. In addition, even the color space is wide, because the Quantum Dot technology, which by the way gives the abbreviation QLED its name, enables the highest possible color space.

So, it becomes clear that a real home theater atmosphere is created for a moderate price! However, even the best image is useless if the colors are washed out from the side. The TV has a great performance, but the viewing angle at which it is maintained is extremely narrow — typical for a VA panel. You should therefore refrain from buying this TV if you are planning to use it for sports evenings with a group of friends or if you have a wide seating area. And while we’re on the subject of the TV’s weaknesses. There are problems with upscaling 480p content, which is especially important with old DVDs or old consoles. According to TCL, there should be an update for this in the future though. If you only want to use the TV for new content, you won’t encounter these problems, and on the positive side, the gray uniformity is quite good compared to other TCL TVs.

Whether sports or games - always smoothly displayed

The motion handling of the TCL TV is really impressive. It has a 120 Hz panel and a fast Response Time of 4 ms. This makes movements look very smooth, and the Black Frame Insertion feature or Motion Interpolation can help if there are any problems with the presentation.

Judder can be completely removed from all sources and the panel is not flicker-free, but at a frequency of 960Hz even sensitive viewers should not notice any flickering.

Well suited for the Next-Gen-Consoles

A quick look at the checklist on the right already shows that the R646 is well suited as a gaming TV. In addition to the good picture quality, which is as important as the features for gaming, the R646 supports everything that the Xbox Series X and PS5 can output.

The 120Hz panel makes 120Fps possible, and the low response time further ensures that everything is displayed smoothly. The input lag is good in itself and really, really good at [email protected] — every action on the controller is directly reproduced on the screen. 2 HDMI 2.1 ports are also included and a Auto Low Latency Mode, as well as a VRR is also supported in the form of AMD Free Sync.

You can already see that there is not much to complain about — only the very limited viewing angle causes couch co-op games to really suffer from the restriction. Thus, we give the “go-ahead” to solo adventurers sitting directly in front of the TV, but those who often play with others on the same screen should look for alternatives.

As with all flat screen TVs, room for improvement

The R646 has a 2.0 Channel Sound System with 15 watts. As is always the case with Flatscreen-TVs, there is a lack of depth to really produce a bass sound that has enough punch. This can make action-packed games and movies sound a bit lackluster.

In general, however, the sound profile is well-balanced. It should also be noted that there are no distortions even at high volumes, and speaking of volume, it gets quite loud. An HDMI eARC port is available, which allows uncompressed Dolby Atmos to be passed on to a suitable Soundbar or HiFi-system. This is recommended for almost all TVs, especially for more expensive ones, because a cheap Soundbar already makes a huge difference.

Now with Google TV instead of Roku

Unlike last year’s 6 Series, the R646 does not use TCL’s own Roku TV, but the smart OS uses the largely more popular Google TV. Although it is not the usual Google TV like Sony and others, since they use their own Version of it, everything runs smoothly here as well and the app selection is huge as usual via the Google Play Store.

A PVR function and timeshift can be used, but unfortunately only a single tuner is installed, which should bother the fewest. The TV’s remote control has shortcuts to Netflix, Prime Video and YouTube, and there is also a built-in microphone to access the TV via voice control, but the remote itself looks very simple — which of course has nothing to do with the user-friendliness.

You definitely get a smart TV here, but as it has become standard, advertisements on the home screen are unavoidable.

A taste of the world of HDR TVs

The TCL R646 can really convince in almost every segment. It has excellent motion handling, which also works well for fast-moving content like sports broadcasts or games.

Speaking of games, the TCL TV can also convince here! There is not much to complain about, apart from the really narrow viewing angle, which of course plays a role in every application if you have a wide seating area or like to watch the TV with several people. It can always be better, but if the budget fits this TV, then you certainly won’t go wrong with it.
