Sony Bravia 8 (XR80) vs TCL C7L

Sony Bravia 8 performs reasonably well in terms of HDR brightness. A maximum brightness level of 880 nits is satisfactory and allows for enjoyable light effects in most scenes. In the tested segments of the films Life of Pi and Sicario 2, the television looks really good, offering vibrant and detailed images that fully convey the atmosphere of these productions.

However, a greater challenge is presented by a scene from the film The Meg, where the screen is entirely very bright. In such situations, the limitations of OLED technology are evident, as the television loses brightness, dropping to about 450 nits. This decline is less satisfactory, especially when the entire scene requires intense lighting. Despite these limitations, Sony Bravia 8 remains a competitive model, offering excellent coverage of the DCI-P3 colour gamut and a BT.2020 standard coverage of 74%. As a result, colours are rich and details are precise, which significantly enhances the quality of HDR content consumption and makes viewing a pleasant experience.

The TCL C7L is, without doubt, an extremely bright TV. In synthetic tests using static test patterns it can reach peak brightness of around 2800 nits. That's a truly phenomenal result, given the price bracket it occupies. Unfortunately, measurements with real film scenes are not as spectacular as the white-square tests. Brightness in real HDR footage on the C7L falls to around 1200 nits. That's still very good, because the vast majority of modern films are graded to that level. However, when small, pinpoint elements appear on screen, the brightness of those details drops dramatically, even to around 400 nits, which reduces the HDR impact. The TV does this deliberately to preserve black levels and avoid excessive blooming. This is somewhat understandable, but it also shows that Mini LED technology is not completely without compromises in this respect. As for the HDR effect itself, alongside brightness the key factor is, of course, colour. Thanks to the use of new 'super' quantum dots, the colours are simply superb and among the best on the market. The TV is able to achieve very wide coverage of the BT.2020 and DCI-P3 colour gamuts, matching the best RGB Mini-LED screens with ease. Best of all, the C7L can maintain such high colour saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED TVs.

The best factory mode available on the Sony Bravia 8 television is IMAX Enhanced, which provides the most cinematic experience, although it is not perfectly set up. The television tries to faithfully reproduce cinematic settings, but certain shortcomings are noticeable. Starting with the white balance, both for SDR and 4K materials, a pronounced blue tint can be observed. This causes the image to appear too cold, stripping it of its naturalness. Tests using Colour Checker show that colours shift towards cooler tones, which may affect the accuracy of colour reproduction and make the image less realistic.

As for brightness and contrast characteristics, the gamma shows a significant drop at the end of the chart. This means that dark details may be too dark and bright elements too bright, resulting in a loss of subtlety and becoming less visible. As seen in the sky - in the comparative photo. In turn, the EOTF curve is well above the reference value, causing bright elements of the image to be too intense. As a result, users may perceive the image as unnatural, and bright areas may lose details, negatively impacting the overall viewing quality.

When it comes to out-of-the-box colours, what's new in TCL TVs, including the C7L model, is the addition of a picture mode called Filmmaker Mode. This is significant because such a mode was not previously available from this manufacturer. As the name suggests, this setting is meant to present the picture with the filmmaker's full intent. After our tests we can confirm that it is, without doubt, the best built-in mode on this TV if you want faithful colour reproduction straight out of the box. However, we certainly wouldn't say it's perfect. Like most devices on the market, this C7L also had some factory calibration errors. The white balance in Filmmaker mode drifted towards a slightly greenish-yellow tint, caused mainly by an excess of the green component and a noticeable shortfall in blue. Of course, this won't be a major drawback for the average viewer, but if you care about perfect whites, natural skin tones and getting the full potential out of the structure of those new "super" quantum dots, the TV really needs professional calibration.

The calibration process of the Sony Bravia 8 television has brought significant improvements in image quality. The white balance has been noticeably enhanced, for both SDR and 4K HDR content, with minimal errors in the middle of the graph. Gamma has proven to be one of the biggest beneficiaries of calibration – it has been completely rid of previous dips, which has significantly impacted brightness stability and better detail reproduction in the darker parts of the image. The EOTF curve has also been levelled, making bright elements of the image appear more natural, and the overall tonal dynamics are now more balanced.

However, the most attention should be paid to colour reproduction, where, despite calibration, certain issues still persist. Sony has omitted the use of a CMS system in this model, which allows for very precise control over colours. As a result, the Colour Checker test for 4K materials still shows significant errors in colour samples. Despite these difficulties, we recommend performing calibration, as the effects are noticeable and significantly enhance image quality, particularly in terms of brightness and contrast.

After professional calibration we managed to greatly improve the situation in the factory Filmmaker Mode. After our corrections, the errors in the ColorChecker test and across the wide colour gamut fell below the threshold of human perception, that is below a value of 3, which is a very good result. The TCL C7L definitely benefits from such a procedure in terms of colour fidelity, and it's hard to deny. Brightness management for HDR content looks a little worse after calibration, though. As I described earlier, even though we set this model up correctly, when you play real film scenes the TV can handle its brightness in a rather peculiar way. It often brightens some elements on screen contrary to the creator's intent, which is clearly visible in the EOTF traces measured from specific films. Despite this defect, or rather a specific characteristic of the television, one thing you can't fault is that after calibration the C7L was able to reproduce colours accurately.

The fluidity of tonal transitions in low-quality materials on the Bravia 8 is poor. Unfortunately, the soft gradation feature (which was available in previous models) is missing, which is a significant downside. The digital noise reduction feature can considerably improve tonal transitions; however, it also tends to remove some details, such as clouds in scenes from the film The Martian, which may not be to everyone's liking. As for digital processing, the Sony XR80 performs quite well. The model in test scenes was displayed without noticeable errors, and the branches in the background are not overly jagged. This shows that the Bravia 8 is capable of effectively processing complex low-resolution image details.

This can be seen as, to some extent, the Achilles' heel of the C7L. Unfortunately, this TV uses the older MediaTek Pentonic 700 chip, which has never been famed for outstanding digital image processing. You can clearly see that in the behaviour of the progressive smoothing function, the feature responsible for reducing jagged edges and removing digital noise. It simply performs very poorly. When set to low, its effectiveness is almost non-existent. The only small plus is that the algorithm does not further spoil the picture or blur details unnecessarily. Upscaling, that is scaling lower-resolution content to 4K, performs slightly better. It is simply adequate and does not stand out against the competition. There is no denying that the C7L would benefit greatly in this regard if the manufacturer opted for the newer Pentonic 800 processor, which is now appearing in an increasing number of rival models.

Sony Bravia 8 offers a maximum refresh rate of 120 Hz, which forms the basis for smooth viewing of dynamic content such as sports and games. This ensures that movements are sharp and fluid. For more demanding users, the Sony XR80 television is equipped with an advanced motion smoothing system, which is divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two are responsible for regulating the degree of blur and smoothness of the image. The third option, concerning clarity, will be described in more detail below. Each of the parameters can be adjusted to personal preferences, allowing users to find the optimal setting tailored to their individual needs.

The TCL C7L uses a native 4K panel with a 144 Hz refresh rate, which at lower resolutions when connected to a PC can even reach up to 288 Hz. These are, of course, very high figures and impressive on paper, but bear in mind that almost all the dynamic content you’ll watch on this TV will still run at around a maximum of 120 Hz. To rein in that motion, the TV’s menu includes a motion-smoothing system called "Motion Clarity". It offers several preset modes, including a user mode that we strongly recommend you set manually using our tried-and-tested guides on our YouTube channel. There are two key sliders available. The first, "Blur Reduction", is responsible for cutting motion blur and improving sharpness in dynamic 60-fps material, such as sports broadcasts. The second slider, "Flicker Reduction", lets you add artificial frames to films and series shot in cinematic 24 or 30 frames per second. This, of course, can completely eliminate the irritating judder that appears during camera movement.

Sony Bravia 8 has significantly improved its compatibility with consoles compared to earlier models. The television supports variable refresh rate (VRR), which eliminates screen tearing, and it synchronises with graphics cards to ensure smooth image display. The automatic low latency mode (ALLM) reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look stunning during gameplay.

The Sony XR80 television also features a Game Bar, allowing quick access to settings and monitoring parameters while gaming. An interesting option is the ability to enable a virtual crosshair on the screen, which can provide a slight edge in shooting games.

A downside is the lack of support for 1440p@120hz resolution, which could facilitate gaming for users with less powerful graphics cards. Additionally, the Sony XR80 only has two HDMI 2.1 ports, one of which is typically used to connect an audio system via eARC, limiting the number of available inputs for connecting next-generation consoles.

When it comes to gaming, the TCL C7L is simply an outstanding TV for players. Thanks to two HDMI 2.1 ports with full 48 Gbps bandwidth, you get access to all the key features required by console owners and powerful PC rigs. There’s a well-working ALLM mode with very low input lag and VRR frame synchronisation that operates over an impressive range from 48 to 288 Hz. Importantly, unlike some rivals, TCL has properly implemented the console HDR10 HGIG profile and supports Dolby Vision in games. The package is completed by a very well designed gamer panel, the Game Bar, which even lets you edit its appearance and change the theme so it perfectly matches the style of your console.

The only thing you can, and even should, criticise is that the TV offers only two full-spec HDMI 2.1 ports, while the other two are older HDMI 2.0. That creates quite a logistical problem. Why? Because one of the fast ports also handles the return audio channel eARC. In practice this means that if you connect a soundbar or home cinema system to the TV, you’ll be left with just one free HDMI 2.1 socket. If you have two consoles at home, or a console and a powerful PC, unfortunately you’ll have to give something up or keep juggling cables at the back of the case while trying to maintain convenient control of the audio system.
