Samsung QN900F vs TCL C7L

QN900F is really a bright TV – it can generate nearly 2000 nits, which is a value 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 TV can use it well. And this is not always perfect. Our tests on movie scenes showed that in scenes such as those from Life of Pi or The Meg, the QN900F can truly shine – literally and figuratively. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more challenging scenes, the issues begin – similar to assessing contrast. When smaller, bright elements appear on the screen, the TV often struggles with the decision: whether to highlight them at the expense of black levels, or perhaps maintain deep black but tone down the brightness. The result of this 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 for a TV of this class.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness levels of around 2800 nits. This is an absolutely phenomenal result, considering the price range it falls into. Unfortunately, the tests with real film scenes are not as spectacular as the measurements of white squares. The brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as the vast majority of contemporary films are mastered at such a value. However, when small, pinpoint elements appear on the screen, the brightness of those details drastically drops – even to about 400 nits – which diminishes the HDR effect somewhat. The television does this intentionally to maintain a better level of black and prevent a huge glare of light. 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, colors are obviously 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 color 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 color saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED televisions.

Testing the QN900F in Filmmaker mode, one quickly noticed the characteristic features of the image despite the fact that this mode is designed to reflect the director's vision. The white balance was not perfect – the television had noticeable deficiencies in blue color. 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 movies where bright shots dominate – for example, scenes in the snow or in strong daylight – this created a slight warming effect, which does not always convey the director's intent. The second noticeable element was brightness management. The QN900F sometimes managed to brighten the image more than necessary. It looked as if the exposure had been slightly "pulled up," causing the scene to lose its naturalness. Shadows were sometimes too shallow, and contrast was 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 evident when comparing its image to what was visible after screen calibration.

When it comes to colors 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 previously unavailable from this manufacturer. By design, as the name itself suggests, the image in this setting is intended to be presented with the full intent 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 color reproduction straight out of the box. However, we definitely wouldn't say that it is perfect. Like most devices on the market, this C7L also had its factory flaws. The white balance in Filmmaker Mode strayed into a slightly greenish-yellow hue, mainly due to an excess of green component and a noticeable lack of blue color. Of course, for the average viewer, this may not be a drastic flaw, but if you care about perfect whites, natural skin tones, and fully unlocking the potential of these new "super" quantum dots, this television is in need of professional calibration.

After calibration, we were able to eliminate 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 color errors are now within the deltaE 2–3 range, so in practice they shouldn't be noticeable during everyday viewing. The biggest improvement is seen in how the television manages brightness in SDR content. Shadows and details are no longer flattened, giving the image depth and naturalness. When it comes to 4K HDR materials, colors themselves are no longer an issue, but some imperfections of the 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 added that this is a much better solution than boosting the entire screen, which would spoil the contrast. It's more of a characteristic of this technology than a typical flaw, but it's worth keeping in mind. The effects of calibration are really very good.

After conducting a professional calibration, we managed to significantly improve the situation in the factory Filmmaker Mode. Following our adjustments, the errors in the ColorChecker test and across the entire wide color 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 an intervention in terms of color fidelity, and it's hard to dispute that. However, the management of brightness in HDR content post-calibration looks a bit worse. As I described earlier – even though we set up this model properly, when we turn on actual film scenes on the TV, it manages its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which is clearly visible in the EOTF graphs measured in specific films. Despite this defect – or rather a specific characteristic of this television – one cannot take away from it that after calibration, the C7L was able to reproduce the colors completely accurately.

If we would like to eliminate non-fluid tonal transitions that can be annoying, for example while watching YouTube, we can use a feature called noise reduction. It works really effectively – it removes the issues with color blending when we set it to Standard level. However, as with most Samsung televisions, this comes with compromises. Although we did not notice that this feature significantly affects the structure of objects in the image, it unfortunately reacts rather aggressively to film grain. Most people will appreciate this effect – the noise is simply removed – but if someone is looking for an image as close as possible to reference settings, then we definitely recommend turning off this option.

As for scaling, which means handling very low-quality content, the QN900F performs really well. On the test screen with the model, the image looked clear, with only slight aliasing that should not bother most viewers. However, it is worth mentioning one issue – the television has problems with so-called overscan, which can cause older content to be slightly cropped. This can manifest itself, for example, with subtitles disappearing from the bottom of the screen.

This point can be, in a sense, called the Achilles' heel of the C7L model. Unfortunately, this TV uses an older MediaTek chipset – the Pentonic 700 – which has never been known for exceptional digital image processing. This is clearly evident in the operation of the gradual smoothing feature, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – after setting it to low, its effectiveness is practically nonexistent. The only small plus here is that the algorithm doesn't spoil anything additional in the image and doesn’t forcibly blur details. The upscaling, that is, scaling the image from lower resolutions to 4K, performs a bit better. It is simply adequate and doesn’t stand out in any particular way compared to the competition. However, it cannot be denied that the C7L would gain significantly in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now increasingly found in many competitive models.

There really isn't anything to complain about here – the QN900F looks very good when it comes to motion. Thanks to the 165 Hz panel in 4K, one can confidently say that this TV is suitable for both watching sports and gaming. The motion smoothness feature plays a key role here. It works remarkably well – not only during sports broadcasts, where it can eliminate blurring and image jitter, but also in games, where the animation becomes clearer and smoother. And of course, if someone likes to experiment with movies – they also have that option. At lower settings, there's a slight graininess and filmic character, while at higher settings, it reaches soap opera effect territory. So everyone can adjust 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, of course, very high values and commendable on paper, but in everyday life, it's worth remembering that nearly all dynamic content you display on this television will still be running around a maximum of 120 Hz. To harness this dynamics, we find a motion smoothing system in the TV's menu called “Motion Clarity.” It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-true guides on our YouTube channel. There we have two key sliders at our disposal. The first one, “Blur Reduction,” is responsible for reducing blurring and improving sharpness in dynamic 60fps materials, such as sports broadcasts. The second slider, “Flicker Reduction,” allows for the addition of artificial frames in movies and series recorded at cinematic 24 or 30 frames per second. This, of course, completely eliminates the irritating 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 is really nice here. The QN900F offers a full set of features that we would expect from a top-tier gaming television – we have VRR, ALLM, Game Bar, and also cloud gaming applications. However, the biggest highlight is the proprietary motion smoothing, which also works in games and – importantly – does not add noticeable delays. This is something we won't find in its other competitors. Unfortunately, there is also something concerning. This year, Samsung has apparently messed something up with its televisions. During the test 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 – 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 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 blunder. Such 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, we have access to all the key features that console owners and powerful PC users require. It offers a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates impressively from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a well-designed gaming panel, the Game Bar, which even allows for customization of its appearance and theme to perfectly match the aesthetics of your console.

The only thing that can – and indeed must – be criticized 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 theater 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 will have to give up something or constantly juggle the cables at the back of the unit while maintaining convenient audio system control.
