Samsung QN85F vs TCL C7L

Although the more than double number of dimming zones compared to its predecessor has not translated into a spectacular jump in black levels and contrast, we definitely felt it in the HDR effect itself. The QN85F is up to 50% brighter than last year's model, making a huge impression in dynamic scenes. The peak brightness can reach nearly 1700–1800 nits, which is truly impressive in this Mini-LED class. The best part is that almost regardless of the scene being viewed, the HDR effect remains strong and vibrant. In four out of five test scenes, the brightness was around 1000 nits, a level that in most cases allows viewers to feel the true magic of this format. Of course, in scene number 4 from the movie Sicario 2, the limitations of Mini-LED technology become apparent – the brightness of the helicopter's spotlight drops to around 500 nits. It's not an outstanding result, but it's still much more acceptable than in last year's model. Samsung deserves applause, as the improvement in brightness in the QN85F is substantial compared to its predecessor. However, it's a pity about a certain trend seen in this year’s televisions – the manufacturer has worsened the color gamut coverage. Although the QN85F has a QLED panel, its result of around 90% DCI-P3 is average, and in the most demanding films, it can lead to less vibrant colors than in the predecessor. Despite this shortcoming, the overall HDR effect is at an excellent level and really makes a big impression in this class of devices.

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.

The Samsung QN85F offers several preset picture modes, but out of the box, the television starts in "Eco" mode. We could actually end the discussion here, because for such a model, using this setting makes no sense – the picture is washed out, unpleasant, and far from what we expect from a television of this class. Therefore, we conducted our tests in the best available mode, which is the Filmmaker mode. Its purpose is to faithfully reproduce what the directors saw while filming, and indeed, this setting performs best among all the factory options. However, this does not mean it is free of flaws.

Both in SDR and HDR, the QN85F strongly highlighted warm colors. This stemmed from a lack of white balance, with a noticeable absence of blue. Additionally, the picture sometimes appeared overexposed – both the gamma brightness characteristic and the EOTF curve indicated that the television has a tendency to blow out scenes. In SDR, the color reproduction errors (Delta E at levels of 4–5) were still acceptable, but in HDR, the inaccuracies became really significant and clearly deviated from what the creators intended to show us. Fortunately, Samsung provides a wide range of calibration tools in its televisions, so – as always – we proceeded with professional calibration to see how much could be improved.

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 calibrating the movie mode, we managed to tame the colors in both modes to nearly perfection – most of them did not exceed an error value of 3, which is the limit of visibility to the human eye. The image became more natural, fuller, and at the same time devoid of the blooming that was noticeable right after taking the TV out of the box. This shows how much potential lies in the QN85F and how well it responds to precise settings. However, this does not change the fact that certain technological barriers cannot be overcome. Despite the significant benefits of calibration, limitations of the panel itself still remain. Although the number of dimming zones has doubled compared to its predecessor, the algorithms controlling the backlighting can manipulate brightness in their own way. Sometimes this leads to slight color distortions or subtly visible halo effects around bright objects. Nonetheless, the reception after calibration is really pleasant and shows how good a screen the QN85F can be if we just take a moment for the right settings.

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.

Although the native tonal transitions on the QN85F perform excellently with 4K materials, we don't always deal with content in the highest resolution. That's when it becomes crucial how the television handles upscaling and digital image processing. This process is managed by Samsung's proprietary processor – AI NQ4 Gen2. In practice, it works very efficiently. If visible color banding or other undesirable phenomena appear on the screen, for example in materials from YouTube, they can be easily smoothed out using the "noise reduction" function. Set to medium, it improves tonal transitions while not excessively blurring desired details. However, it's important to remember that – as with most Samsung televisions – this feature significantly affects the film grain. Therefore, during movie screenings, it's advisable to use it cautiously to maintain the natural character of the image.

The upscaling itself looks very good. Test materials in lower resolutions were displayed sharply and clearly, with a lot of detail. The only drawback remains the issue of overscan, which is cutting off the edges of the screen. In most situations, this is not noticeable, but with very old materials below HD quality, there may be instances where part of the image on the left side is slightly cropped.

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.

Motion blur and fluidity of motion in the QN85F is a topic worth discussing in more detail, as the television is equipped not with a standard 120 Hz panel, but with a 144 Hz panel. The additional hertz will primarily be appreciated by PC gamers, but the mere presence of such an option can be seen as a nice addition and a sign of the times – it’s hard to complain about the trend towards faster panels, since in practice, each of us would like the image to be as fluid as possible. However, the most important thing is how the television handles typical 120 Hz refresh rates – in the case of consoles, sports, or films recorded at 24 or 30 frames per second. And here, the QN85F performs really well. In movies, you can easily adjust the character of the image thanks to the “picture clarity” function, where we find two adjustable sliders. Key for viewing sessions is the one responsible for reducing motion blur. Lower values give the image a more cinematic character with preserved “frame rate,” while higher values lead to a strong smoothing that resembles television theater.

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.

The Samsung QN85F makes a great impression in terms of features for gamers. It has four HDMI 2.1 ports, so we can easily connect several devices at once. There is also variable refresh rate (VRR) to prevent screen tearing, as well as automatic game mode (ALLM), which allows the TV to switch to the appropriate settings automatically when we start the console. Additionally, it supports refresh rates of up to 144 Hz – something that PC gamers will particularly appreciate, but the mere fact that such an option is available shows that Samsung is fully supporting gamers. The Game Bar panel deserves praise as well. It's a quick glance at key parameters – from frame rate to refresh mode to shortcuts for picture settings. Instead of sifting through the entire menu, everything is at our fingertips, which turns out to be really convenient in practice. However, the most interesting addition is the Game Motion Plus feature. It's nothing more than motion smoothing, transferred into the gaming world. When enabled, the picture becomes smoother, sometimes it even looks as though we're getting several more frames, and importantly, the response delay does not increase enough to interfere with gameplay. This solution truly sets Samsung's 120Hz TVs apart from the competition.

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

The only serious downside remains the lack of proper HGiG support. This is a standard responsible for correct tone mapping in HDR games, ensuring that brightness and contrast are displayed as intended by the creators. Without HGiG, we have to adjust the brightness manually, which doesn’t always yield ideal results. The feature was available in previous models, but it disappeared from the QN85F after one of the updates. We hope that Samsung will quickly fix this issue, and we will keep checking to see if it has been resolved.

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.
