Sony X90L vs TCL C7L

HDR on the Sony X90L television looks promising. The luminance chart indicated that the TV has a solid power reserve, achieving a maximum of 1000 nits in synthetic tests. But how does this perform in real-world scenarios? In scenes such as the opening of Life of Pi or the final sequence from The Meg, the TV is capable of delivering that power on HDR content, reaching around 800 nits. Unfortunately, displaying small light elements on a black background, like in the scene from Sicario 2, presents greater challenges for the X90L – here the results reach around 600 nits. Nevertheless, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The colour gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, which indicates good colour reproduction in HDR content.

The TCL C7L is without doubt an extremely bright TV. In synthetic tests with static patterns it can reach peak brightness of around 2800 nits. That's a phenomenal result, given the price bracket it occupies. Unfortunately, tests with real film scenes aren't as spectacular as measurements using white squares. Brightness in real HDR shots falls in the C7L to around 1200 nits. That's still very good, because the vast majority of modern films are mastered to about that level. However, when small, pinpoint elements appear on screen, the brightness of those details drops drastically, even to roughly 400 nits, which somewhat weakens the HDR effect. The TV does this deliberately to preserve deeper black levels and to avoid a large halo of light. That's understandable to an extent, but it also shows that Mini LED technology is not without compromises in this area. As for the HDR experience itself, alongside brightness the key factor is of course colour. And thanks to the use of new 'super' quantum dots, the colours are simply outstanding and among the best on the market. The TV can achieve very wide coverage of the BT.2020 and DCI-P3 colour gamuts, matching the best RGB Mini-LED displays with ease. Best of all, the C7L can maintain such high colour saturation regardless of the scene shown, which is often a problem for competing RGB Mini-LED TVs.

The best mode on Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinema experience, the colour reproduction out of the box is average here. In the case of lower quality materials, such as HD – regular television or YouTube – it's worth paying attention to the white balance. It suffers from a shortfall in red and excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite acceptable, but a slight boost can cause the image to appear washed out and look as if it’s behind a light fog.

For 4K HDR content, the situation is somewhat different. The white balance shows a significant boost in blue, which makes the image unnaturally sharp and gives it an artificial feel. Such an exaggeration in colour reproduction may not appeal to everyone, especially if one prefers more realistic tones. Additionally, the EOTF curve in Sony X90L looks quite acceptable at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the correct brightness to avoid overexposing larger elements.

When it comes to out-of-the-box colours, a new feature in TCL TVs – including the C7L model – is the presence of a new picture mode called Filmmaker Mode. This is significant news, as such a mode was not previously available from this manufacturer. By design, as the name suggests, the picture in this setting is intended to be delivered with the full intent of the film's creator. After our tests, we can confirm that it is undeniably the best built-in mode in this TV if you value true-to-life colour reproduction straight out of the box. However, we certainly wouldn’t say it is perfect. Like most devices on the market, this C7L also had its factory faults. The white balance in Filmmaker Mode leaned towards a slightly greenish-yellow hue, mainly due to an excess of green component and a noticeable lack of blue. Of course, for the average viewer, this won’t be a drastic flaw, but if you value perfect whites, natural skin tones, and harnessing the full potential of these new "super" quantum dots from the structure, then the TV is begging for professional calibration.

Sony offers many tools for improving picture quality, including two extra picture modes that we decided to use during testing and apply calibration to. This solution greatly simplifies the calibration process and is very effective, provided you have the right tools. In the case of HD content, white balance was almost perfectly aligned – only one shade of grey exceeds an error value of "1", which is a great result. The same can be said for the brightness characteristic (gamma), which presents almost perfectly, with microscopic deviations of around 0.01.

For 4K HDR content, the situation is not as ideal. Although white balance has been significantly improved, it was not possible to completely eliminate the dominance of blue. Nevertheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that picture distortions are practically unnoticeable. When it comes to the EOTF curve, it's worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the TV struggles with illuminating very small elements, which is due to the limited number of backlight zones. Despite these minor errors, it's thanks to the calibration that the IMAX Enhanced mode in the Sony X90L makes watching movies feel like a true cinema experience.

After a professional calibration we managed to greatly improve performance in the out-of-the-box Filmmaker Mode. After our adjustments the errors in the ColorChecker test and across the wide colour gamut dropped below the threshold of human perception, that is below a value of 3, which is a very good result. The TCL C7L clearly benefits from such treatment in terms of colour fidelity and it's hard to argue otherwise. A bit worse, however, is brightness management with HDR content after calibration. As I described earlier, even though we set this model up correctly, when you play real film scenes on the television it can handle its brightness in a rather peculiar way. It often brightens certain elements on screen contrary to the filmmaker's intent, which is clearly visible on the EOTF curves measured in specific films. Despite this defect, or rather a specific characteristic of this television, one thing is undeniable: after calibration the C7L was able to reproduce colours accurately.

The Sony X90L television features a smooth tonal transition function known as Gentle Gradation, which is incredibly effective. Even at the "low" setting, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which gives a natural effect and makes everything look cohesive. It's clear that the engineers have really put effort into this aspect, creating a solution that impresses and performs well in everyday use. This means that even when watching content like regular television or YouTube, where the image is by nature not stunning, you can enjoy a smooth, coherent, and visually pleasing experience.

This could, in a sense, be called the Achilles' heel of the C7L. Unfortunately, this TV uses an older MediaTek chipset, the Pentonic 700, which has never been known for exceptional image processing. You can see that clearly in the operation of the progressive smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply performs very poorly — set to low, its effectiveness is practically nil. The only small plus is that the algorithm doesn't introduce extra artefacts or unnecessarily blur fine detail. Upscaling, that is scaling lower-resolution sources up to 4K, fares a little better. It's simply adequate and nothing special compared with the competition. It's hard to deny that the C7L would benefit greatly in this area if the manufacturer opted for the newer Pentonic 800 processor, which is now appearing in an increasing number of rival models.

Sony X90L with a 120 Hz display is an excellent choice for both gamers and film enthusiasts. The television is equipped with the Motion Flow smoothing feature, which allows for adjusting motion smoothness using two sliders: "smoothness" and "clarity". The "smoothness" slider controls the level of motion fluidity, which affects the reduction of image stuttering, while "clarity" is used to reduce blurriness and enhance motion sharpness, which is especially useful in dynamic scenes.

TCL C7L uses a native 4K panel with a 144 Hz refresh rate, which at lower resolutions when used with a PC can even reach 288 Hz. These are, of course, very high figures and look good on paper, but in everyday use it's worth remembering that almost all dynamic content you play on this TV will still run at around a maximum of 120 Hz. To tame 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. You get two key sliders there. The first, "Blur Reduction", reduces smearing and improves sharpness in dynamic 60 fps material, such as live sports broadcasts. The second slider, "Flicker Reduction", lets you add artificial frames to films and series shot at cinematic 24 or 30 frames per second. That, of course, completely gets rid of the annoying judder during camera-move shots.

Sony X90L is a TV that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth playback of high-resolution games at high frame rates. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which ensures smooth gameplay without frame tearing. The Game Bar is an added bonus – an intuitive tool that provides quick access to essential settings and gaming features, making it easier to control the gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. It lacks support for HGiG, a standard that many gamers consider crucial for accurate HDR representation in games. While the TV supports Dolby Vision, which theoretically could enhance image quality in games, the practical implementation of this feature is problematic. Dolby Vision in game mode comes with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, Dolby Vision cannot be enabled alongside VRR. This means that despite numerous advantages, gamers seeking the perfect HDR in games may feel unsatisfied.

When it comes to gaming, the TCL C7L is simply an outstanding TV for players. With two full‑bandwidth HDMI 2.1 ports at 48 Gbps, you get access to all the key features required by console owners and high‑end PCs. It offers a well‑working ALLM mode with very low input lag and VRR frame sync that operates across an impressive 48 to 288 Hz range. Importantly, unlike some rivals, TCL has implemented the console HDR10 HGIG profile correctly and supports Dolby Vision in games. The package is rounded off by a very well designed player panel, the Game Bar, which even lets you edit its appearance and change the theme so it perfectly matches the look of your console.

The only thing you can — and should — criticise is that the TV only provides two full HDMI 2.1 ports, while the other two are older HDMI 2.0. That creates quite a practical problem, because one of those fast ports also handles the eARC (enhanced Audio Return Channel). In practice, that means if you connect a soundbar or home theatre system to the TV, you’ll be left with only one free HDMI 2.1 input. If you have two consoles or a console and a powerful PC at home, you’ll unfortunately have to give something up or keep swapping cables at the back if you want convenient control of your audio system.
