Samsung Q8F vs TCL C7L

In terms of brightness, the Samsung Q8F performs surprisingly well for a TV without local dimming. It measures up to 500 nits, which in practice means that most movie and series scenes look pleasant, and it cannot be faulted for lacking the "HDR effect." In films like Life of Pi or The Meg, the screen can burst with bright light, delivering a level of lighting effect that is satisfying. It struggles more in challenging moments—such as dark scenes with single bright points. The global dimming used causes the TV to darken the image to maintain deep blacks, but at the expense of detail brightness. This is clearly visible in the scene from Sicario 2, where the brightness of the helicopter lights dropped to around 200 nits. This is a deliberate design choice that gives the impression of deeper blacks but takes some shine away from individual elements, and one should simply keep that in mind. Regarding colour reproduction, the Q8F uses quantum dot technology, which expands the colour gamut. A coverage of the DCI-P3 palette at 91% can be considered a decent result, although it is not a record-breaking figure compared to other QLEDs.

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.

We decided to check out the Filmmaker mode because right out of the box it gave us the best picture. However, that doesn't mean it was perfect. The white balance had too much of a blue and red tint, causing the whites to lean towards a slight purple-pink hue. Such imbalance affected the visibility of virtually all colours, which is clearly seen in the comparison photo below. The brightness characteristics in SDR content were quite well calibrated, although in HDR materials we noticed that the TV didn't always handle its global dimming well — at times the screen was too dim, while at other times it could suddenly brighten up. Fortunately, issues related to colours can be effectively corrected with calibration tools, so we decided to get to work.

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 correct the white balance to almost perfection. Older SDR content looks fantastic — most errors are within a value of 2, which is definitely below the threshold of human perceptibility. In HDR, we also brought the white balance to an acceptable level, but a different problem arises here. So why are there still relatively large errors in colour reproduction? This is mainly due to the limited colour palette and the way the television manages brightness. The global dimming technique used does not give the user control in the settings, so analysing the EOTF curve in HDR films, it's clear that the Q8F can modify luminance on its own. This can be seen as a limitation, but still, the image after calibration is much more enjoyable to watch than in the factory version.

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.

Let's see how the Q8F handles older content, which often has poor quality. Starting with the positives: the upscaling works really well. The TV performs nicely with both classic television and materials from YouTube, not giving the impression that we're dealing with something completely unattractive. It struggles more with content in very low resolutions, such as 576p — the image can be cropped, and unfortunately, the overscan phenomenon cannot be disabled. Moreover, the digital processing does not look great either. The noise reduction feature, instead of removing unwanted artefacts, smooths out almost everything: film grain (which many viewers desire) disappears along with the texture of the image, and actors' faces start to resemble characters from cheap Turkish soap operas. It's hard to consider this option useful — it's best left completely off. Perhaps Samsung will refine the function’s performance in updates, but for now, it’s difficult to view it as anything other than an unnecessary addition.

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.

Due to the applied 60 Hz panel, it's hard to call the Q8F a television made for gaming or watching sports. The panel isn't particularly fast, making motion blur clearly visible. If you were expecting a spectacular, almost 'stadium-like' experience during broadcasts, you might feel a bit disappointed. Fortunately, for movies and series, Samsung hasn't given up on the motion smoothing function. It's nothing more than a smoother that allows for improved fluidity of productions recorded at 24 or 30 frames per second. This way, you can decide for yourself whether you prefer a more fluid, 'television-like' image or to retain the cinematic character. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

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.

It's not entirely clear what Samsung has messed up this year with its TVs, but the Q8F isn't free from all the confusion with updates and shortcomings. While its older cousin, the Q67D, could still be recommended with a clear conscience to casual gamers, it's hard to find a reason to do so here. Aside from the automatic game mode and the attractively designed Game Bar, we get practically nothing that could appeal to gamers. The lack of proper HGiG implementation is a major issue, especially since the feature simply disappeared after the 1126 update. The situation with VRR is even worse. Even though it appears in the manufacturer's brochures and shows up in the Game Bar, we couldn't get it to work. The Xbox Series X console wouldn't allow it to be activated at all, and the option remained greyed out and inactive. It's difficult to praise such a TV even to casual gamers, which is a shame because Samsung has had a strong selling point in the gaming segment for years.

[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.

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.
