Samsung QN80F 100" vs TCL C7L

When it comes to HDR in Filmmaker mode, the QN80F can make a great first impression. Our laboratory tests have shown that under the best conditions, the television is capable of achieving brightness exceeding 1200–1300 nits. These are truly excellent results, making HDR effects in many films look incredible. The television is simply bright enough not to need to artificially adapt the image – the bright parts of scenes have the right 'power' and actually look like a light source. Of course, the laboratory is one thing, and everyday viewing is another. In practice, in film scenes, brightness generally oscillates in the range of 700–1100 nits. These are still great values that, in most cases, provide a strong sense of realism and make the lights on the screen truly capable of blinding. The problem arises in exceptionally challenging sequences, where, like almost every mini-LED, it reveals its limitations. A good example is Sicario 2: the scenes with the helicopter in the night sky look much weaker, and the lights lose intensity, dropping to around 370 nits, making it hard to speak of serious admiration. To this, we must add the issue of colours. Although we are dealing with a QLED, the coverage of the DCI-P3 colour palette is around 90%. This is a rather average result for a quantum dot television. In practice, this means that some colours may appear less saturated than we would expect, especially in demanding HDR productions.

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.

The Samsung QN80F performs best in Filmmaker mode, which is designed to replicate the creators' intentions as accurately as possible. And indeed – this is the mode in which the television showcases its potential. But let’s not kid ourselves, it is far from perfect. In SDR content, the issue of white balance came to the forefront. Slightly lacking greens and a noticeable excess of reds caused the screen to take on a pinkish hue. You don't even need meters to notice this – in everyday viewing, the subtly shifted colour palette could be quite noticeable, and in colour checker tests, the colours would literally "pop" out of their reference fields. With HDR content, the situation looked a bit better, as the white balance was closer to ideal, but another problem arose – brightness management. The EOTF curve often caused the image to become too bright, which spoiled the sense of contrast, and in dynamic scenes, it led to a slight "flicker" in perception. We had already mentioned this when discussing black levels and HDR. The good news, however, is that Samsung provides a lot of tools for improvement. The QN80F allows for truly detailed calibration, including a 20-point white balance. And since the manufacturer has left us so many options, we decided to check how the television would perform after a thorough adjustment.

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 calibrating the QN80F, it immediately showed that it was capable of much more. The previous pinkish tint disappeared, and the white balance finally looks like it should – natural and without excessive deviations. The colours gained depth, and the image became more saturated and cohesive, making watching films simply more enjoyable. It's a bit like removing a light haze from the screen – suddenly everything appears sharper and clearer. The management of brightness has also improved. The television no longer gets easily lost in dynamic shifts, and the EOTF graph shows that the curve tracking is significantly more stable. Of course, there are no miracles – the limited number of zones still means that small bright elements can be slightly washed out, but that's a result of the design itself, not the settings. After this correction, the QN80F feels like a more mature piece of equipment, and watching films finally provides the satisfaction expected from a television even in a higher class.

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.

With lower quality materials, such as films from YouTube or older television recordings, the QN80F can display its strengths and weaknesses. If strange colour transitions or artefacts start to appear on the screen, it is worth using the noise reduction function. The best setting is at "medium" – it smooths out problematic sections while not blurring the entire image. However, one compromise must be remembered: this function always removes film grain. If someone enjoys its presence in older productions, it is better to keep the reduction turned off, as the grain simply disappears regardless of the setting.

Resolution scaling, or upscaling, is another strong point of Samsung. The QN80F may not be the best television on the market in this regard, but it performs very well in its price range, which is very important for such a large size as a 100-inch screen. Even lower quality materials can gain a second life – the image becomes sharper, more readable, and overall much more pleasant to perceive. A weak point remains overscan, which is the slight cropping of edges in very low resolutions (e.g., 576p), something that has been a longstanding issue for Samsung. Fortunately, this is practically of no consequence when watching HD and 4K content on a daily basis.

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.

The QN80F features a 144 Hz panel, and this is evident in practice – with full refresh, the image is remarkably smooth, and motion blur remains at an acceptable, barely noticeable level. However, this mode is primarily aimed at PC gamers. The most important reference point in everyday use remains the 120 Hz refresh rate, and this is where a certain discrepancy arises. During the UFO test, we noticed a splitting of the contours of rapidly moving objects – it looked as if the television had the BFI (Black Frame Insertion) feature permanently activated, which in practice led to an unpleasant effect of double edges. We do not yet know whether this is a software issue or a characteristic of this model, but in its current form, such behaviour is hard to commend.

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.

The Samsung QN80F gives the impression of a television designed with gamers in mind. On the list of advantages, we have a 144 Hz panel, four full-featured HDMI 2.1 ports, complete support for VRR and ALLM, as well as one of the best-designed gamebars on the market. Added to this is the Game Motion Plus motion smoother, which also works in games without actually increasing input lag, making the QN80F an absolute standout in this category. In practice, this means you can enjoy smoother images without losing responsiveness, which is a dream for many console gamers!

As is usual with Samsung, there is a lack of Dolby Vision in games, and this is no longer surprising. However, we were much more surprised that in the models from 2025… the HGIG feature has disappeared. This feature allowed consoles such as the PlayStation 5 and Xbox Series X to perfectly adjust HDR tone mapping to the capabilities of the television. In the current firmware of the QN80F, this option is simply missing – it seems more like a mistake than a conscious decision by the manufacturer, but on the day of testing, we must acknowledge that HGIG is not available. Due to this one absence, the QN80F, instead of being an almost ideal television for gamers, becomes a device that is only "almost" ideal. This is quite a shame because, aside from this, Samsung has created a model that truly sets a high standard in the gaming hardware segment.

[UPDATE] We have updated our Samsung television tests for the 2025 model year due to the release of software version 1131, which has restored the crucial gaming feature HGiG.

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.
