Sony BRAVIA 5 (XR5) vs TCL C8L / QM8L

Looking at similar results in terms of black levels and contrast, we expected the same stable performance as last year's model when it comes to HDR content. Unfortunately – and this must be said plainly – there has been a regression here that is hard to overlook. The paradox is that the peak brightness of the Bravia 5 can be impressive: in our synthetic tests, the television reached around 1000 nits in HDR. Sounds great, right? The problem is that this power does not always translate effectively to all movie scenes. When small, pinpoint elements appear on the screen, something that was usually refined with surgical precision in the case of Sony clearly falters this time. The algorithms try to maintain deep blacks around small objects, but the side effect is that details can be dimmed to the point of becoming barely visible. A case in point is the movie Sicario 2 – there, in some scenes, small light sources practically vanished as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with a greater amount of light, the Bravia 5 shows that it can shine: literally and figuratively. At that point, the television achieves values in the range of 600–800 nits, which we observed in both synthetic tests and during movie screenings. The impression is truly positive; the brightness adds dynamism, and the colors appear vivid and fresh. However, there remains a certain dissonance. We feel a slight confusion because it is evident that something has gone the wrong way. Technological advancement – more zones, greater backlight power – has not been supported by the refined image management we usually associate with Sony. Fortunately, there are elements that have not been worsened and are instead at a very high level. We are talking about color reproduction. Thanks to the use of the PFS filter, the color gamut coverage is excellent – about 97% of DCI-P3 and 75% of BT.2020. These values allow for a truly wide color reproduction, giving films a natural and cinematic character.

In terms of HDR, the TCL C8L turns out to be a hellishly bright television – and I mean literally. On a synthetic chart of 5%, our measuring equipment indicated a result exceeding 4500 nits. This is a result that is downright cosmic, considering that reference director monitors, which we often refer to in our materials, typically operate around 4000 nits. Does this mean that the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not exactly. Dry synthetic tests are one thing, and real movie images are another. In real, varied scenes, the C8L achieves a peak of around 1600 nits. This is still a very good result, ensuring a very high level of HDR dynamics, but also clearly lower than what the manufacturer boasts in the specifications. The trouble starts with very small flashes of light – then brightness can drastically drop to around 600 nits. The algorithm tries at all costs to maintain deep black and minimize halo effect, but it does so at the expense of HDR impact. This is perfect evidence that laboratory charts rarely correspond to what we ultimately see on the screen.

Huge applause is due for color reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the true jaw-dropper is the measurement of the extremely demanding BT.2020 space. The C8L achieves as much as 90% in it, placing it alongside today's top screens that boast RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene displayed. Of course, one must remember that content mastered for such a wide gamut in films or series is still a rarity. However, the mere fact that the panel has such a "color reserve" deserves immense admiration.

Sony Bravia 5 was of course tested in the best possible mode, which is the Cinema mode. Right out of the box, it offers the most natural colors, definitely better than anything provided by the "eco" or "dynamic" modes, which are more suitable for a store display than a living room. However, the Cinema mode itself does not guarantee that we can always expect cinematic image quality. In SDR content, we had practically no major complaints – the slightly warm white balance made the scenes take on a somewhat golden tone, but it was nothing that was glaringly obvious. However, the problem arose with HDR materials. Here, the color reproduction simply looked poor. The white balance was severely off – with an excess of blue and a noticeable lack of red. At times, it even resembled the store "super vivid image" mode, where everything is overexposed and artificially boosted.

This state of affairs made managing brightness seem too aggressive as well. The EOTF graph clearly showed that the television had issues with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was hard to remain indifferent here – which is why we quickly decided to go for calibration.

We tested the TCL C8L in the best factory picture mode available in this TV’s menu for image fidelity. That, of course, is Filmmaker Mode, which appeared in this brand’s software relatively recently (a year ago in the "K" series). Thanks to it, an average user can get a pretty good color reproduction straight out of the box, although it is certainly not a perfectly tuned mode. Looking at the factory white balance of our unit, both in SDR and HDR material, the red component was clearly lacking, which made the image noticeably cooler and caused a slight shift toward bluish-green tints. The issue of brightness management is also ambiguous, as we mentioned earlier. While for SDR content the gamma linearity is actually correct and holds steadily at the reference value of 2.4, in HDR things look much worse. Tracking the EOTF curve clearly shows the TV has a significantly boosted brightness across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that in a mode that by definition should avoid that. Of course, like every sample in our lab, this one also underwent professional calibration, and its results are shown below.

After calibration, the situation changed drastically. We managed to tune the white balance so that entire scenes began to look more natural, and the image gained coherence and elegance. In HDR, we finally got rid of that unwanted blooming effect that had previously ruined some shots. Suddenly, it turned out that the Bravia 5 can extract much more from films than the first contact "straight out of the box" suggested. Yes, if we take a look at the graphs and compare them with the reference patterns, we can see that the start of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritize the visibility of details – and in practice, it’s hard to disagree with that. We prefer to see the texture of the material on the screen rather than a pitch-black blob that obliterates all nuances.

The calibration itself made a significant difference. After about an hour spent on adjustments, we felt that the picture resembled that from the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we love Sony televisions: because once we fine-tune them, they can reward us with an image that captivates for long hours.

As you can see, the results of a professional calibration of the TCL C8L are really promising, thanks to the extensive adjustment tools the manufacturer put at our disposal in the menu. Above all, we were able to completely correct the white balance — we eliminated the red deficiency, so the image finally stopped drifting toward unwanted cool tones. After that adjustment, errors in the ColorChecker test fell to near-reference levels, regularly landing below a Delta E of 2, which is below the threshold of human perception.

If the test patterns look this perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with actual movie material (I recommend enabling the EOTF filter when watching movies), you can see that in most scenarios the TV still reacts to HDR metadata its own way. As a result, the picture can be slightly over-brightened and not faithful to the creators' intent, and it was precisely this lack of consistency with real films that cost the C8L a few points.

Bravia 5 carries within it the genes of Sony, which remain intact – and thank goodness for that, because we are talking about absolutely remarkable digital image processing. There is a reason that for years it has been believed that it is this brand of television that sets the standard for how a screen should handle lower-quality materials. If someone is still watching classic television, old movies, or YouTube in lower resolution, here they get equipment that can turn such content into a surprisingly pleasant experience. On board, we find several tools worth activating. The first of these is "digital noise reduction." Set to a medium level, it works almost flawlessly – smoothing tonal transitions that usually pose the biggest challenge with low-quality materials, while not introducing any artificial artifacts. Importantly, it also does not remove the filmic character, or the natural grain that is an intentional element in many productions. Another advantage of Bravia 5 is the upscaling capabilities of the XR processor. The image presented after scaling is soft yet sharp and clear. The contours of characters are well-defined, and backgrounds retain their structure without excessive artificial sharpening. It’s hard to find a better television for watching lower-quality content – Bravia 5 only confirms why Sony is regarded as the benchmark in this field.

This year the C8 series and higher models received probably the biggest and most anticipated upgrade in TCL’s history, and it specifically concerns digital image processing. The C8L is the lowest-end model in the manufacturer's lineup to be equipped with the latest flagship chip, the MediaTek Pentonic 800 (listed in the menu as MT9655). Thanks to its processing power, the feature called "Gradual Smoothing" finally works as it should. The algorithm effectively eliminates unwanted posterization (ugly tonal transitions/color banding), doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although evaluating this element can be mostly academic, because the differences between today's TVs in this class are very subtle. The most important takeaway is that TCL finally has nothing to be ashamed of compared to the competition.

Bravia 5 has a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches, or spectacular action movies. However, the real magic begins only when MotionFlow comes into play – Sony's proprietary smoothing technology. Thanks to it, we can adjust the character of the image to our own preferences. The “smoothness” slider allows us to transition from a cinematic vibe with a slight “jitter” of the film frame to an almost theatrical fluidity, where every ball in the game glides across the screen like on a string. The higher the value, the smoother and more fluid it is; the lower – the more cinematic and natural. In the options, we also find an additional setting that Sony has called “clearness.” This is nothing more than the BFI function (which stands for black frame insertion), which aims to improve motion clarity. It sounds great in theory, but in practice, you need to use it with great caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, there can also be contour doubling. Therefore, if we want to use it, we recommend the lowest possible level – “1” out of the available ten. This way, we gain a little better motion clarity without risking a loss of half the image brightness.

The TCL C8L is equipped with a fast panel that has a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, who rely on consoles or TV broadcasts, will use a steady 120 Hz. It is at 120 Hz that motion processing algorithms handle image rendering for movies, series, and sports. In the TV’s menu you’ll find a "Motion Clarity" option that lets you adjust the motion smoothing to your preferences. The algorithms handle cinematic material at 24 or 30 frames per second (fps) as well as dynamic sports broadcasts at 50 or 60 fps, maintaining appropriate smoothness.

In the Bravia 5, there is significant progress compared to the X90L model from two years ago. The television offers literally everything that its predecessor had, but this time the issues that could irritate gamers have been fixed. The problems with setting up variable refresh rate (VRR) have disappeared, and there are no longer any issues with configuring HDR content in HGiG mode. In short: we get a device that simply works as it should without any fuss. The Bravia 5 thus has everything one could expect from a modern gaming television – and it could be advertised with the slogan "ready for PS5" without exaggeration. This is a statement we couldn't make about the X90L model. Hats off, Sony!

It's just a shame that in such a relatively high-priced model, a complete set of four HDMI 2.1 ports is missing. In everyday use, this won't be a problem for most people, but if someone has a console, soundbar, and additional equipment connected via HDMI, at some point there will be a need to either choose or juggle cables.

For gamers – especially for those with powerful PCs and several consoles at the same time – the TCL C8L is a true beast. It’s the first model in the manufacturer’s lineup equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly thanks to the new Pentonic 800 processor we wrote about earlier. Additionally, the TV seamlessly supports virtually every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels and full frame synchronization (VRR) operating in an impressive range of up to 288 Hz. We’re also talking about standards like G-Sync or FreeSync from Nvidia and AMD. When it comes to image display standards, there are also no compromises: the C8L offers complete support for HDR formats in games, including gaming Dolby Vision and the HGiG profile. All of these features can be conveniently managed from a very readable game bar (Game Bar), which we can customize according to our preferences. From a purely gaming perspective, there really isn’t anything to complain about in the C8L – well, maybe aside from the previously mentioned slight ghosting. But other than that? It’s an unflawed machine for gamers.
