TCL RM7L vs SONY BRAVIA 3 II (XR35M2)

TCL RM7L is a bright TV. In our measurements its peak brightness hovered around 1600 nits. That’s noticeably less than the C7L, which can get close to 2600 nits, but in real-world film scenes the difference between the models isn’t that large. In less demanding shots, where plenty of bright elements appear on screen, the RM7L can sustain around 1000 nits, and sometimes even a bit more, approaching 1500 nits. It performs worse in dark scenes with small points of light; then their brightness can fall to about 500 nits. This behaviour isn’t random. The TV deliberately dims small elements to better control the backlight and preserve higher contrast. This comes at the expense of their intensity, but it’s typical for TVs with local dimming in a similar price range.

Colour gamut coverage

In HDR brightness isn’t the only thing that matters, colour does too. Here the RM7L has a lot to show. Colours are strongly saturated and the wide colour gamut is one of its main strengths. In our 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 colours look best, while in films their saturation can be a little lower than on SQD Mini LED or QD-OLED TVs. The backlight design itself is interesting. The RM7L doesn’t use the classic red, green and blue LED set. TCL used two green LEDs and one blue, with red produced via a PFS phosphor. You can see this in spectrometer measurements, but it doesn’t have a major impact on the picture. Colours are still rendered correctly.

The Bravia 3 II isn't exactly a TV that tries to impress with brightness. In our measurements it reached around 450 nits, so it's well short of the brightest models on the market. That doesn't mean HDR is just a paper feature here. Compared with standard SDR material, the brightest parts of the image can already punch through noticeably, and highlights, light sources and 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 the screen contains lots of bright elements. Then the Bravia 3 II can give a taste 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 bold, spectacular HDR we’re left with a merely competent picture.

Colours

The Bravia 3 II uses a QLED panel, although technically it doesn't employ a traditional quantum-dot layer. Instead Sony has used a PFS phosphor-based solution, which performs a very similar role: it allows for more saturated reds and greens, and thus reproduces a much wider colour gamut. In our measurements coverage of the DCI-P3 gamut was about 94%, and of the very wide BT.2020 around 74.4%. Those are good results for this class of hardware, which means the Bravia 3 II has no problem showing suitably saturated colours in HDR material. Colours don't look washed out, and the more intense hues can look really attractive.

Factory colours were checked 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 reproduce the image as faithfully as possible to the filmmakers' intent. On the RM7L it was indeed the best calibrated mode, though not without faults. The biggest issue was the white balance. An excess of red and blue made the image shift slightly toward pink tones. This was visible in both SDR and HDR. In addition, the brightness response was slightly boosted, so the picture looked a little brighter but at the same time less contrasty than it should.

In Professional mode the Bravia 3 II delivers a fairly good level of colour reproduction straight out of the box. In SDR the most noticeable issue is a slightly low gamma, which makes the midtones a little brighter. The white balance isn't perfect either; as brightness increases a bit of blue and red drops away, so whites can sometimes appear a touch warmer with a faint greenish tint. These aren't mistakes that immediately jump out when watching a film. Average error values hover around 3, so the factory setup can be considered quite good. The situation in HDR is similar. Here too there's a slight lack of blue, so the picture is marginally warmer than the reference, but the difference isn't large enough to be distracting during normal viewing.

Thanks to a fairly extensive calibration menu we managed to correct the vast majority of the issues described earlier. The biggest change was the white balance. After calibration it looks very good, so the image has lost its pinkish tint and become much more neutral. The luminance response has also improved. Both the SDR gamma and the HDR EOTF curve are now much closer to the reference values. The picture is no longer unnecessarily bright, and darker parts look more natural and have greater depth. Better luminance accuracy has also affected the colours, 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 in its own way and doesn’t always stick exactly to the reference curve. You can see this mainly in some darker scenes, where the TV can either slightly lift the shadows or darken them completely. That’s where the earlier impression of a slightly brightened, less contrasty image came from. Even so, the calibration delivers a very good result here. It removes the most visible errors and, above all, makes the picture much closer to how it should look.

After calibration you can get a lot out of SDR material. The white balance was set almost perfectly, gamma practically matches the reference value, and average colour errors fell from around 3 to about 1. That’s already the level at which differences from the reference image are very hard to spot in practice. The Bravia 3 II therefore shows that despite its place in Sony’s range it has quite a bit of potential for precise picture tuning. Improvement is also visible in HDR, although here you can’t avoid all the limitations of the TV itself. Once the colours are evened out 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 gently darkens parts of the image. That isn’t ideal from a reference point of view, but in this particular TV it also has an advantage. With no local dimming and average black levels this behaviour slightly reduces the visibility of the backlight in darker scenes and helps preserve a stronger sense of contrast. You could say Sony is partly masking the limitations of the panel this way, rather than trying at all costs to stick to the reference brightness.

Upscaling and digital image processing are not the RM7L’s strong points. TCL has used a MediaTek Pentonic 700 chipset here, labelled MT5896, which isn’t among the best processors at handling lower-quality sources. The biggest issues appear with heavily compressed content from YouTube or regular broadcast TV. The processor can’t effectively hide posterisation and the characteristic banding between shades. The feature meant to smooth these issues does little to help and can also interfere with the picture too much, smoothing faces and fine textures, for example. For that reason it’s best not to use it.

Plain upscaling to 4K looks better. Lower-quality sources are reasonably sharp and retain a sufficient amount of detail. It’s not on a par with the best processors on the market, but for everyday viewing the result is perfectly acceptable.

Bravia 3 II is Sony's first TV to use the new MediaTek Pentonic 800 chip, and you can see a few changes in the image processing. Starting with the basics: the upscaling itself is decent. The TV can sensibly upscale lower-resolution material and doesn't have a strong tendency to over‑emphasise jagged edges or other source imperfections. With regular broadcast TV or lower-quality streaming material the picture therefore remains quite attractive.

We have more reservations about the digital image processing. In this model Sony has replaced the well-known "Smooth Gradation" function with a new setting called "Digital Noise Reduction". Its job is basically the same: to smooth out ugly tonal transitions and artifacts caused by heavy compression. Unfortunately, this function performs noticeably worse than before. At the "Large" setting (the only one that had any visible effect) the TV can smooth away too many image elements at once, which causes film grain to disappear and object textures or even skin to start looking unnatural. Worse still, the effect is not particularly stable. When there's more motion in a scene, the function's effect noticeably weakens and at times it looks as if the TV stops intervening in the image altogether. So for everyday viewing we wouldn't recommend using it at a high level. It can help on static shots, but the trade-off is often too much loss of detail.

The RM7L uses a 144 Hz VA panel, so right from the start it's well prepared for sports, games and other dynamic content. The high refresh rate also gives the motion interpolation more room to work, so it can generate additional frames. On the RM7L it performs well and, when set correctly, can noticeably improve motion smoothness without producing 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. Sony has, however, managed that issue very well here. Fast-moving objects remain sharp, and the characteristic motion trails and blur are reduced to a very low level, if not to zero. It's one of the least motion-blur-prone 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.

When it comes to gamer-focused features, there's almost nothing but praise for the RM7L. The TV supports ALLM, VRR, Dolby Vision Gaming and works correctly with HGiG, so it's hard to point to any major gaps in that area. In practice that means automatic switching to a low-latency mode, smoother motion 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 has added a few extra options too, such as an on-screen reticle and brightening of dark areas, which can be useful in some titles. The biggest downside comes from using the Pentonic 700 processor. Only two of the four HDMI ports support the full HDMI 2.1 standard. With a single console that won't be a big issue, but if you hook up two consoles and a PC you might run out of ports, especially since one of those ports may also be needed for eARC and a soundbar.

The Sony Bravia 3 II is a very good TV for gamers, although not everything has been solved the way we’d like. The biggest change concerns the connectors. 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 problems that has hung over this manufacturer’s TVs for years. You can connect several devices at once and on each input use the device’s full capabilities, including VRR and ALLM. There’s also a simple Game Bar that lets you check the 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. That won’t be an issue 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 doesn’t let you disable tone mapping on the Bravia 3 II, so the TV keeps processing HDR even when you’d prefer to leave that task to the console. It’s easiest to spot during HDR setup—the checkerboard test pattern doesn’t disappear at the point where it should based on the TV’s actual capabilities. That doesn’t mean HDR in games will look bad. You just need to set up a little differently and, rather than relying on the pattern, manually set the peak brightness to about 450 nits. So the issue can be worked around, but you should know about it before you start configuring your console.
