TCL RM7L vs SONY BRAVIA 3 II (XR35M2)

The TCL RM7L is a bright TV. In our measurements its peak brightness hovered around 1600 nits. That's clearly less than the C7L, which can approach 2600 nits, but in real movie scenes the difference between the two models isn't that big. In less demanding shots with many bright elements on screen, the RM7L can hold around 1000 nits, and sometimes a bit more, approaching 1500 nits. It performs worse in dark scenes with small highlights; then their brightness can fall to around 500 nits. However, this behavior is not accidental. The TV intentionally dims small elements to better control the backlight and maintain higher contrast. This comes at the cost of their intensity, but it's typical behavior for local-dimming TVs in a similar price bracket.

Color gamut coverage

In HDR it's not only brightness that matters, but also color. And here the RM7L has a lot to show. Colors are strongly saturated, and a wide color gamut is one of its bigger strengths. In measurements it reached about 96% of DCI-P3 and around 83% of BT.2020. It's worth remembering, though, that on a TV with this kind of backlight the result can vary depending on the scene. On test patterns colors look best, while in movies their saturation can be a bit lower than on SQD Mini LED or QD-OLED TVs. The backlight construction itself is also interesting. The RM7L doesn't use the classic red, green and blue diode set. TCL used two green diodes and one blue, and obtains the red color using a PFS phosphor. You can see this in spectrometer measurements, but it doesn't have a major impact on the picture. Colors are still produced correctly.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it's far from the strongest designs on the market. That said, HDR here is not just a paper feature. Compared with regular SDR material, the brightest parts of the image can already punch through, and reflections, highlights, or stronger exposures have a bit more energy and stand out better from the rest of the scene. You can see this best in simpler shots where many bright elements appear on screen. Then the Bravia 3 II can give a hint of a higher-dynamic-range picture. The problem only starts with more demanding content, where much greater brightness headroom is needed. There the TV quickly shows its limits and instead of strong, striking HDR we get only a correctly rendered picture.

Colors

Bravia 3 II uses a QLED-type panel, although technically it does not use a traditional quantum-dot layer. Instead Sony applied a PFS phosphor-based solution that serves a very similar role: it allows for more saturated reds and greens and thus lets the TV display a much wider color gamut. Measurements showed about 94% coverage of the DCI-P3 gamut and about 74.4% of the very wide BT.2020. Those are good results for this class of hardware, meaning the Bravia 3 II has no problem showing adequately saturated colors in HDR content. Colors don't look washed out, and the more intense shades can look really attractive.

We checked the factory colors in Filmmaker Mode, the best picture setting available to the user. TCL has been using it in its TVs for two years, and its purpose is to present the image as faithfully as possible in line with the creators' intent. On the RM7L this was indeed the best-calibrated mode, although it wasn't without flaws. The biggest issue was the white balance. An excess of red and blue caused the picture to take on slightly pinkish tones. This was visible in both SDR and HDR. Additionally, the luminance response was slightly boosted, which made the image appear a bit brighter but also less contrasty than it should have been.

In Professional mode the Bravia 3 II, straight out of the box, delivers a fairly good level of color reproduction. In SDR the most noticeable issue is a slightly low gamma, which makes the midtone areas a bit brighter. White balance is not perfect either; as brightness increases there is a slight lack of blue and red, so whites can sometimes take on a slightly warmer, mildly greenish tint. However, these are not errors that immediately stand out while watching a movie. Average error values hover around 3, so the factory preset can be considered quite good. The situation is similar in HDR. Here again there is a slight deficiency in the blue component, so the image is a touch warmer than the reference, but the difference is not large enough to be significantly distracting during normal viewing.

Thanks to a fairly extensive calibration menu, we were able to correct the vast majority of the errors described earlier. The biggest change was to the white balance. After calibration it looks very good, so the image lost its pinkish cast and became much more neutral. The luminance response itself also improved. Both the SDR gamma and the HDR EOTF curve are now much closer to the reference values. The image is no longer unnecessarily brightened, and darker areas look more natural and have more depth. Better luminance accuracy also affected the colors, which after calibration are noticeably more accurate. Not everything could be set perfectly, though. In HDR material the RM7L still interprets part of the signal its own way and does not always follow the reference curve exactly. This is most apparent in some darker scenes, where the TV can either slightly lift the shadows or darken them completely. That was the source of the earlier impression of a slightly brightened, less contrasty image. Even so, the calibration delivers a very good result here. It removes the most visible errors and, above all, makes the image much closer to how it should look.

After calibration you can get a lot out of SDR content. The white balance was set almost perfectly, gamma practically matches the reference value, and average color errors fell from around 3 to about 1. That's a level at which differences from the reference image are, in practice, very hard to detect. The Bravia 3 II therefore shows that despite its position in Sony's lineup it has quite a lot of potential for precise picture tuning. Improvements are also visible in HDR, although here you can no longer work around all of the TV's limitations. After equalizing the colors it's easier to notice that the EOTF curve in film material runs slightly below the reference value in places, meaning the Bravia 3 II slightly darkens part of the image. That's not ideal from a reference standpoint, but in this particular TV it also has an advantage. With no local dimming and average black levels, this behavior slightly reduces the visibility of the backlight in darker scenes and helps maintain a greater sense of contrast. So you could say Sony partially masks the limits of the panel that way, rather than trying at all costs to stick to the reference luminance.

Upscaling and digital image processing are not the RM7L's strong suit. TCL used a MediaTek Pentonic 700 SoC here, designated MT5896, which isn't among the best processors at handling lower-quality content. The biggest problems show up with heavily compressed material from YouTube or regular broadcast TV. The processor can't effectively hide posterization and the characteristic color banding. The feature meant to smooth them does little here, and it often interferes too much with the picture, smoothing faces or fine textures, for example. For that reason, it's best to simply leave it off.

Straightforward upscaling to 4K looks better. Lower-quality sources remain reasonably sharp and retain enough detail. It's not on par with the best processors on the market, but for everyday viewing the result is entirely acceptable.

The Bravia 3 II is Sony’s first TV to use the new MediaTek Pentonic 800 chipset, and you can see a few changes in image processing. Starting with the basics: upscaling is solid. The TV can sensibly upscale lower-resolution material and doesn’t have a strong tendency to overemphasize jagged edges or other source imperfections. With regular broadcast TV or lower-quality streaming the picture remains quite pleasing. We have more reservations about the digital image processing. In this model Sony replaced the well-known "Smooth Gradation" feature with a new setting called "Digital Noise Reduction." Its role is essentially the same: to smooth unpleasant tonal transitions and artifacts caused by heavy compression. Unfortunately, this feature performs noticeably worse than before. At the "Large" setting — the only one that noticeably affected the picture — the TV can smooth away too many image elements at once, causing film grain to disappear and surface textures or even character skin to start looking unnatural. Worse, the effect is not very consistent. When a scene contains more motion the function’s effect weakens significantly and at times it looks as if the TV stops intervening in the image altogether. For everyday viewing we therefore don’t recommend using it at a high level. It can help on a static shot, but the price is often too much loss of detail.

The RM7L uses a 144 Hz VA panel, so right out of the box it's a TV well suited for sports, gaming, and other fast-moving content. The high refresh rate also gives the motion interpolation engine more room to work, allowing it to generate extra frames. On the RM7L it works well, and with the right settings it can noticeably improve motion smoothness without causing an excessive soap opera effect.

Motion handling is definitely one of the Bravia 3 II's strongest points. The TV uses a 120 Hz VA panel, a solution that by nature, despite the high refresh rate, doesn't always cope well with motion blur. Here Sony has managed to get that problem very well under control. Fast-moving objects remain sharp, and the characteristic trails and blurring are reduced to a very low level, if not to zero. It's one of the least smearing LCD TVs we've had the chance to test. Interestingly, in this respect the Bravia 3 II can even outperform the much more expensive flagship True RGB series: the Bravia 9 II.

You can say almost nothing but good things about the RM7L when it comes to gamer features. The TV supports ALLM, VRR, Dolby Vision Gaming and works correctly with HGiG, so it’s hard to point out any major omissions in that area. In practice this means automatic switching to low-latency mode, a smoother picture with variable frame rates, and accurate brightness reproduction in HDR games. There’s also a handy Game Bar. From it you can quickly check the frame rate, VRR status, signal format, and aspect ratio, and change key settings without leaving the game. TCL also added a few extra options, like a crosshair and brightening of dark parts of the image, which can be useful in some titles. The biggest downside comes from the use of the Pentonic 700 processor. Only two of the four HDMI ports support the full HDMI 2.1 standard. With a single console this won’t matter much, but when connecting two consoles and a PC you may run out of space. Especially since one of those ports may also be needed for eARC and a soundbar.

Sony Bravia 3 II is a very good TV for gamers, although not everything has been handled the way we'd like. The biggest change concerns the connections. For the first time in a Sony TV we get four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the long-standing issues that has plagued the manufacturer's TVs. You can connect several devices at once and use each input's full capabilities, including VRR and ALLM. There's also a simple Game Bar that lets you check key signal parameters and change a few useful settings, such as black level, when you want to improve visibility in darker parts of a game.

There are, however, two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. This won't be a problem for everyone, but people using that resolution on a console or PC, for example to get higher frame rates in certain games, will have to choose 1080p. We have more reservations about HGiG support. Sony does not allow disabling tone mapping on the Bravia 3 II, so the TV continuously processes HDR content even when you would prefer to leave that task to the console. You can most easily notice this during HDR setup. The checkerboard pattern does not disappear at the point corresponding to the TV's actual capabilities. That doesn't mean HDR in games will look bad. You just need to approach the setup a bit differently and, instead of relying on the pattern, manually set the peak brightness to about 450 nits. The issue can be worked around, but you should know about it before you start configuring your console.
