Samsung QN900F vs TCL C7L

QN900F is a seriously bright TV – it can generate nearly 2000 nits, which is a level that remains unattainable for most models on the market. But the ability to achieve such brightness isn’t everything – it also matters whether the TV can make good use of it. And here it’s not always perfect. Our tests on cinematic scenes showed that in scenes like those from Life of Pi or The Meg, the QN900F can really shine – both literally and figuratively. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more demanding scenes, things start to get tricky – similar to assessing contrast. When smaller, bright elements appear on the screen, the TV often struggles with the decision of whether to highlight them at the cost of black levels or perhaps maintain deep blacks but tone down the brightness. The result is situations where, for example, in the movie Sicario 2, the brightness dropped to just 200 nits, making details barely visible. The dimming algorithms could definitely be better, considering the class of this television.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static patterns, it can achieve peak brightness of around 2800 nits. This is a phenomenal result, considering the price range it occupies. Unfortunately, tests with real movie scenes are not as spectacular as measurements of white squares. Brightness in real HDR footage drops in the C7L model to around 1200 nits. This is still a very good result, as this is the value at 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 drops – even to around 400 nits – which somewhat diminishes the HDR effect. The television does this intentionally to maintain a better black level and to avoid a huge light bloom. This is somewhat explainable, but it also shows that Mini LED technology is not completely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colours are of course key here. And these, thanks to the use of new, “super” quantum dots, are simply outstanding and among the best on the market. The television can achieve around 90% coverage of the ultra-wide colour gamut BT.2020 and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such high colour saturation regardless of the scene being displayed, which can often be problematic in competing RGB Mini-LED televisions.

Testing the QN900F in Filmmaker mode, the distinct characteristics of the image quickly became apparent, despite this mode being designed to reflect the director's vision. The white balance was not perfect – the television had noticeable deficits in blue. This caused the entire scene to take on a warmer tone, as if someone had applied a subtle filter in shades of yellow and orange to the image. In films where bright shots dominate – for example, scenes in the snow or under strong daylight – this gave an impression of a slight warmth that does not always convey the director's intention. The second noticeable element was the management of brightness. The QN900F sometimes brightened the image more than necessary. It looked as if the exposure had been slightly "pushed up," which caused the scene to lose some naturalness. Shadows could be too shallow, and contrast slightly weakened. These are not disqualifying errors, but for a television in this price range, it is clear that the Filmmaker mode has not been perfected one hundred percent. This is particularly noticeable when we compare its image to what was visible after the screen calibration.

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.

After calibration, we managed to reduce the errors in white balance and adjust them to a level that can be considered acceptable. It's not perfect, but definitely better than the factory settings. Most colour errors now fall within the deltaE 2–3 range, so in practice, they shouldn't be noticeable during everyday viewing. The biggest improvement is evident in how the television handles brightness in SDR content. Shadows and details are no longer flattened, giving the image depth and naturalness. As for 4K HDR materials – colours themselves are no longer an issue, but one can still notice some imperfections in Mini-LED technology. The QN900F tends to excessively dim the smallest bright elements, causing them to sometimes disappear from view. However, it's worth noting that this is a much better solution than boosting the entire screen, which would ruin the contrast. This is more of a characteristic of the technology rather than a typical flaw, but it's worth keeping in mind. The effects of the calibration are really very good.

After conducting a professional calibration, we were able to greatly improve the situation in the factory Filmmaker Mode. Following our adjustments, the errors in the ColorChecker test and across the entire wide colour gamut dropped below the threshold of human perception – that is, below a value of 3, which is indeed a very good result. The TCL C7L definitely benefits from such a treatment in terms of colour fidelity, and it's hard to deny that. However, the management of brightness in HDR content after calibration appears to be a bit worse. As I described earlier – even though we set this model up properly, when we turn on real film scenes on the television, it can manage its brightness in quite a peculiar way. It often brightens certain elements on the screen in a manner inconsistent with the creator's intent, which is visibly apparent on the EOTF graphs measured in specific films. Despite this flaw – or rather, this specific characteristic of the television – one cannot take away from it: after calibration, the C7L was able to reproduce the colours flawlessly.

If we want to get rid of awkward tonal transitions that can be annoying, for example, while watching YouTube, we can use a feature called noise reduction. It works really effectively – it eliminates issues with colour blending when set to Standard level. However, as with most Samsung TVs, this comes with some compromises. Although we didn't notice this feature having a significant impact on 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 upscaling, or dealing with very low-quality content, the QN900F performs really well. On the test pattern with a model, the image looked clear, with only slight jaggedness that shouldn't bother most viewers. However, it’s worth mentioning one issue – the TV sometimes struggles with so-called overscan, which means older content may be slightly cut off. This can manifest, for example, with disappearing subtitles at 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 image processing. This is clearly visible in the functioning of the gradual smoothing feature, 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 none. The only small plus here is that the algorithm doesn't mess up anything else in the image and doesn't forcefully blur details. The upscaling, that is, the scaling of the image from lower resolutions to 4K, performs 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 being found in an increasing number of competitive models.

There’s really nothing to nitpick here – the QN900F looks great when it comes to motion. Thanks to its 165 Hz panel in 4K, you can confidently say that this TV is suited for both watching sports and gaming. The motion smoother plays a key role here. It works brilliantly – not just with sports broadcasts, where it can eliminate blurring and image judder, but also in games, where animation becomes clearer and more fluid. And of course, if someone likes to experiment with movies – they have that option as well. At lower settings, you can see a slight graininess and a filmic quality, while higher settings introduce a soap opera effect. So everyone can tailor the picture to their preferences, and the TV has the power to handle it.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which can even ramp up to 288 Hz at lower resolutions when using a PC. These are certainly very high and commendable figures on paper, but in everyday life, it's worth remembering that almost all dynamic content you display on this television will still revolve around a maximum of 120 Hz. To tame this dynamism, the TV menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode, which we highly recommend setting manually using our tried-and-true guides on our YouTube channel. You’ll find two key sliders available. The first one, "Motion Blur Reduction," is responsible for reducing blurring and improving sharpness in 60fps dynamic content, such as sports broadcasts. The second slider, "Flicker Reduction," allows for the addition of artificial frames in movies and shows recorded at cinematic 24 or 30 frames per second. This naturally allows for the complete elimination of the annoying stutter effect 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's really good here. The QN900F offers a full set of features that we would expect from a top-notch gaming TV – we have VRR, ALLM, Game Bar, as well as cloud gaming apps. However, the biggest standout is its proprietary motion smoother, which also works in games and – importantly – does not add noticeable input lag. This is something we won't find in other competitors. Unfortunately, there is also something concerning. This year, Samsung has clearly messed up something with its TVs. During the testing of the QN900F before its update, it had the HGIG feature, which allowed for perfect adjustment of HDR settings for consoles. However, according to our procedures, we always update the hardware to the latest version – to give the manufacturer a chance to fix any issues. And here… it went the other way.After the update, the HGIG feature disappeared from the menu, making proper 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 little mishap. 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. We have a well-functioning ALLM mode with very low input lag and VRR frame synchronization, which operates within an impressive range from 48 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 gamer panel, known as Game Bar, which even allows for editing its appearance and changing the theme to perfectly match the style of your console.

The only thing that can – and should – be critiqued here is the fact that the television only offers 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 theatre system to the television, you’ll only have one available 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 constantly juggle cables at the back of the unit while maintaining comfortable audio system control.
