Samsung QN900F vs TCL C7L

QN900F is truly a bright television – it can generate nearly 2000 nits, a figure that remains unattainable for most models available on the market. But the mere ability to achieve such brightness is not everything – it also matters whether the television can make good use of it. And here, it is not always perfect. Our tests on cinematic test patterns showed that in scenes such as those from Life of Pi or The Meg, the QN900F can truly shine – literally and metaphorically. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more demanding scenes, challenges arise – similar to when assessing contrast. When smaller, bright elements appear on screen, the television often struggles with the decision: should it highlight them at the expense of black levels, or perhaps maintain deep blacks while toning down brightness. The result is situations where, for example, in the film Sicario 2, brightness dropped to just 200 nits, making details barely visible. Dimming algorithms could definitely be better for a television of this class.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness of around 2800 nits. This is an exceptionally phenomenal result, considering the price range it occupies. Unfortunately, tests of real film scenes are not quite as spectacular as measurements of white squares. Brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as this is the value to which the vast majority of contemporary films are mastered. However, when small, point-like elements appear on the screen, the brightness of these details drastically decreases – even down to around 400 nits – which diminishes the HDR effect somewhat. The television does this deliberately to maintain a better level of black and to avoid a giant light bloom. This is somewhat explainable, but it also shows that Mini LED technology is not entirely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colours are of course key here. And those, thanks to the use of new "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve about 90% coverage of the ultra-wide BT.2020 colour gamut and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such a high saturation of colours regardless of the scene being displayed, which often poses a challenge for competing RGB Mini-LED televisions.

Testing the QN900F in Filmmaker mode, the characteristic features of the image were quickly noticeable, even though this mode is designed to reflect the director’s vision. The white balance was not perfect – the television displayed distinct deficiencies in the blue colour. This made the entire scene take on a warmer tone, as if someone had applied a subtle filter in shades of yellow and orange. In films where bright shots dominate – for example, scenes in the snow or in strong daylight – this gave the impression of slight warmth that did not always convey the director's intent. The second noticeable element was the management of brightness. The QN900F could sometimes brighten the image more than necessary. It looked as though the exposure had been slightly 'pulled up', causing the scene to lose its naturalness. Shadows were sometimes too shallow, and the contrast slightly weakened. These are not disqualifying errors, but for a television in this price range, it is evident that Filmmaker mode has not been perfected one hundred percent. This is particularly noticeable when we compare its image with what was seen after the screen calibration.

When it comes to colours straight out of the box, a new feature in TCL televisions – 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 available from this manufacturer before. By design, as indicated by the name itself, the image in this setting is meant to be presented with the full intention of the film's creator. After our tests, we can confirm that it is undoubtedly the best built-in mode on this television if you care about faithful 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 flaws. The white balance in Filmmaker Mode tended to shift towards a slightly greenish-yellow hue, primarily caused by an excess of green and a clear deficiency of blue. Of course, for the average viewer, this won't be a drastic flaw, but if you care about perfect whites, natural skin tones, and unlocking the full potential of those new "super" quantum dots, then the television is crying out for professional calibration.

After calibration, we managed to eliminate errors in white balance and adjust them to a level that can be considered acceptable. It is not perfect, but it is definitely better than the factory settings. Most colour errors now lie within the deltaE 2–3 range, so in practice, they should not be noticeable during everyday viewing. However, the most significant improvement is evident in how the television manages brightness in SDR content. Shadows and details are no longer flattened, which gives the image depth and naturalness. As for 4K HDR material – colours themselves are no longer an issue, but some imperfections of Mini-LED technology can still be observed. The QN900F tends to dim the smallest bright elements too much, causing them to sometimes disappear from view. However, it should be noted that this is a much better solution than boosting the entire screen, which would spoil the contrast. This is more of a characteristic of this technology than a typical flaw, but it is worth keeping in mind. The effects of calibration are truly very good.

After conducting a professional calibration, we were able to significantly improve the situation in the factory mode Filmmaker Mode. Following our adjustments, errors in the ColorChecker test and across the entire wide colour gamut fell below the threshold of human perception – that is, below a value of 3, which is truly an excellent result. The TCL C7L definitely benefits from such an operation in terms of colour fidelity, and this is difficult to dispute. However, the management of brightness in HDR content post-calibration does not look as good. As I described earlier – even though we set up this model appropriately, when we turn on real film scenes on the television, it manages its brightness in quite a peculiar way. It often highlights certain elements on the screen contrary to the creator's intention, which can be clearly seen in the EOTF graphs measured in specific films. Despite this defect – or rather the specific trait of this television – one cannot deny that after calibration, the C7L was able to reproduce colours completely accurately.

If we want to eliminate jarring tonal transitions that can be irritating, for example, while watching YouTube, we can use a feature called noise reduction. It works really effectively – it removes issues with colour blending when we set it to Standard level. However, as with most Samsung televisions, this does involve some compromises. Although we did not notice this feature significantly affecting the structure of objects in the image, it unfortunately reacts quite aggressively to film grain. Most people will likely appreciate this effect – the noise is simply removed – but if someone is looking for an image as close as possible to reference settings, we definitely recommend turning this option off.

When it comes to scaling, or dealing with very low-quality content, the QN900F performs really well. On the test card with the model, the image appeared clear, with only slight aliasing that shouldn't bother most viewers. However, it is worth mentioning one issue – the television sometimes has problems with so-called overscan, which can cause older content to be slightly cropped. This might manifest, for example, in subtitles disappearing from the bottom of the screen.

This point could be called, in a sense, the Achilles' heel of the C7L model. Unfortunately, this television uses an older chipset from MediaTek – the Pentonic 700 – which has never been known for outstanding digital picture processing. This is clearly visible in the performance of the smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – when set to a low level, its effectiveness is practically nonexistent. A small credit should perhaps be given here for the fact that the algorithm does not additionally ruin the picture or blur details forcibly. The upscaling, which is the scaling of the image from lower resolutions to 4K, fares a bit better. It is simply adequate and does not stand out in any particular way against the competition. However, it cannot be denied that the C7L would greatly benefit in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now found in an increasing number of competing models.

There really is nothing to complain about here – the QN900F looks very good in terms of motion. With a 165 Hz panel in 4K, it can confidently be said that this television is suitable for both watching sports and gaming. The motion enhancer plays a key role here. It works brilliantly – not only during sports broadcasts, where it can eliminate blurring and image shaking, but also in games, where the animation becomes clearer and smoother. And of course, if someone likes to experiment with films – they also have that option. At lower settings, a slight graininess and cinematic character can be seen, while at higher settings, it takes on a soap opera effect. In other words, everyone can adjust the picture to their preferences, and the television has the power to handle it.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which at lower resolutions – when using a PC – can even ramp up to 288 Hz. These are, of course, very high values and commendable on paper, but in everyday life, it is worth remembering that almost all dynamic content you display on this television will still rotate around a maximum of 120 Hz. To tame this dynamism, the television's menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-tested guides on our YouTube channel. There, we have two key sliders at our disposal. The first one, "Motion Blur Reduction," is responsible for reducing blurring and improving sharpness in dynamic 60-frame materials, such as sports broadcasts. Meanwhile, the second slider, "Flicker Reduction," allows for the addition of artificial frames in films and series recorded at cinematic 24 or 30 frames per second. This certainly eliminates the irritating stutter in images during camera movement shots.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

It really is nice here. The QN900F offers a full set of features that we would expect from a top-end gaming television – we have VRR, ALLM, Game Bar, and also cloud gaming applications. However, the biggest standout is the proprietary motion smoother, which also works in games and – importantly – does not introduce noticeable lag. This is something we won't find with its other competitors. Unfortunately, there is also something concerning. This year, Samsung has evidently messed something up with its televisions. During the testing of the QN900F before its update, it had the HGIG feature, which allowed for perfect adjustment of HDR settings for the console. However, according to our procedures, we always update the equipment to the latest version – in order to give the manufacturer a chance to fix any shortcomings. And here… it turned out the opposite.After the update, the HGIG feature disappeared from the menu, making the correct configuration of the console for HDR practically impossible. It was supposed to be complete – 165Hz, four HDMI 2.1 ports, a full gaming package… but unfortunately, it turned out to be a small blunder. What a shame.

When it comes to gaming, the TCL C7L is simply an outstanding television for gamers. With the presence of two full-bandwidth HDMI 2.1 ports at 48 Gbps, it provides access to all the key features that console and high-end PC owners require. It has a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates in an impressive range from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured a proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a very well-designed player panel, known as the Game Bar, which even allows you to customise its appearance and change the theme to perfectly match the style of your console.

The only thing that can – and indeed should – be critiqued here is the fact that the television offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. This creates quite a significant logistical problem. Why? Because one of those fast ports also supports the eARC audio return channel. In practice, this means that if you connect a soundbar or home cinema system to the television, you will only have one free HDMI 2.1 port left. If you have two consoles or a console and a powerful computer at home, unfortunately, you'll have to give something up or frequently juggle cables at the back of the unit while maintaining convenient control over your audio system.
