Samsung Q7F vs TCL C69K / Q6C

Unfortunately, the Samsung Q7F is not one of the bright televisions, which directly impacts the quality of HDR films. The peak brightness of the panel is only around 250 nits, which is definitely insufficient for claiming a true cinematic experience. In practice, the HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During testing of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performance came from shots with small, intensely glowing elements – the global dimming technique used reacted very aggressively in those cases, dimming the entire screen to maintain the black effect. However, it is worth noting the presence of a QLED coating that broadens the colour spectrum. For a budget QLED model, the Q7F performs quite decently here: the DCI-P3 colour gamut coverage is around 93%, and BT.2020 reaches 70%. This means that despite the low brightness, the colours can still look quite vivid and attractive.

In terms of brightness, TCL C69K / Q6C is a moderate model. In optimal movie conditions, it shows its full potential, reaching a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, giving a cinematic glow. However, it's important to keep in mind that when managing the backlight zones, there are situations where parts of the image are dimmed, and at times become barely visible. This suggests that there is still a lack of proper optimization of the algorithms, although considering the technical parameters in this price range, the overall construction still looks very good.

The reproduction of factory colours in the Samsung Q7F is definitely not one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There’s too much red on the screen, while blue is lacking. The effects are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image appear a bit unnatural, while bright areas of the scene can seem unrealistic. The problems are even more evident in HDR content. The charts show that the TV has significant errors in the Color Checker palette, which results in visible inaccuracies in the real image. In practice, this means that colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can be dimmed. This makes the image seem flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. In HDR materials, this is particularly frustrating because every detail matters. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the lighting or, conversely, suppresses elements that should attract the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

The Filmmaker Mode, which has been introduced in this year's TCL TVs (including the C69K / Q6C), is definitely the best choice "to start with". This is the mode we recommend for everyday movie and series viewing. Unfortunately, as is often the case, best does not mean perfect. In SDR materials, the image turned out to be too warm, with a strong red tint in the white balance. The opposite impression was had with HDR content – here the image became cooler than it should have been, due to an excess of blue. Additionally, there is the brightness characteristic, which at times resulted in overexposures. In practice, this translated to fairly noticeable errors in color tests, which is difficult to accept in a mode branded as "by the creators".

After professional calibration, we managed to bring the Q7F to order – at least in terms of SDR content. The image in this mode looks really good: the white balance has been set correctly, the colours appear natural, and the errors in the colour palette have dropped to levels practically invisible to the eye. Gamma behaves exemplary, and the only minor flaw remains a slight lightening of smaller elements, which stems from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly more challenging to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to appear unnatural – what was meant to be subtly darker can sometimes be overly bright, and the bright parts of the image can occasionally be dimmed. The final effect is better than in factory settings, but it’s clear that the construction limitations of the Q7F do not allow for fully utilising the potential of HDR materials.

Through white balance adjustment, we were able to significantly reduce the tendency of ChooseTV C69K / Q6C to distort colours, which resulted in a very good final outcome. After calibration, the problem of excessive warming of scenes in SDR and over-cooling of the image in HDR disappeared. However, it's worth analysing the brightness characteristics more closely. While in SDR content there are few complaints – the picture looks really good, especially in older films, TV programmes, or on YouTube – it performs much worse with HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the actual construction become evident. This model tends to excessively brighten small parts of the frame, while in other situations, it darkens the entire scene too much. The effect of calibration is therefore undeniable, and in terms of colourimetry, ChooseTV C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

Upscaling and digital image processing in the Q7F is a bit of a rollercoaster. On one hand, we have really nice upscaling – weaker sources look better than you might expect. The image becomes clearer, sharper, and even older films or free-to-air TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients is still there. It's a bit of a shame because we expected more from a model that is aimed at users looking for a display for SDR content.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content is presented acceptably, and due to the lack of overscan issues, the image is displayed in full without any cropping. However, don’t expect miracles – materials of very low quality won’t gain a second life here, as the image processor has its limitations.

On thin lines and details, there is noticeable jaggedness, which reveals the lack of more advanced image enhancement algorithms. It's also a shame that the C69K / Q6C lacks a feature for smoothing tonal transitions. As a result, in older films or video materials, color banding can be visible and may become distracting during extended viewing.

Motion blur and motion fluidity in the Q7F is probably the most budget-friendly aspect of this television. The 60 Hz panel makes the motion blur quite noticeable, especially in dynamic scenes, and it's rather hard to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long trail, similarly, the ball in a football match would leave behind streaks.

On the positive side, the presence of motion smoothing is worth noting. In films, it really makes a difference – especially since most materials are recorded in 24 frames. Here we can decide whether we prefer a more "cinematic" image, with a slight judder typically found in cinema, or a smoother, more “TV-like” one. This actually works quite well and helps improve the viewing comfort for series or movies.

The use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. This represents an important step forward compared to its predecessor (C655 PRO), which only offered 60 Hz at 4K. The difference is particularly noticeable when watching sports or gaming – the ball, players, and dynamic action in games are displayed more clearly and without losing detail. An interesting feature is also the panel's ability to operate at 240 Hz (which the manufacturer does not officially mention) – we will revisit this topic in relation to the PC gaming mode. TCL has also added a feature for movie fans: “Motion Clarity.” This allows users to adjust the picture to their own preferences using two simple sliders. We can either leave the visible film frame or opt for a very smooth one, "

Features for gamers in the Samsung Q7F are a topic that stirs up quite a few mixed emotions. On one hand – no sensible person expected miracles here because after all, it’s a 60 Hz TV and from the start, it was clear that it wouldn't be a device for squeezing the maximum out of a console or PC. On the other hand, since the manufacturer promised specific solutions in the promotional materials, it’s only natural that we wanted to see them in practice. At the outset, it's pretty decent. The automatic game mode (ALLM) works, so there's no need to manually fiddle with settings; the console switches the TV to low latency mode on its own. We also have the Game Bar, which looks impressive and allows you to peek at a few basic parameters without leaving the game. And this is where the good news ends.

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

The biggest problem with the Q7F is VRR, or rather its absence. Yes, a relevant icon appears in the menu, you can even see it in the Game Bar, but throughout the test, the feature remained dormant and could not be activated in any way. The issue with HGiG is even more painful; this option was actually available at the start, but after the software update, it disappeared completely, which is simply unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play more relaxed titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they'll be disappointed. This is not a TV you buy with the intention of gaming, and it's better to be aware of this before making a purchase.

TCL C69K / Q6C is a television that can confidently be called equipment designed for gamers. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, which is a panel with the most important settings within easy reach – handy when we want to change something quickly during gameplay (e.g., aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is noteworthy. However, this option is mainly for PC gamers looking to go below native 4K resolution. In this case, the television can spread its wings and show additional smoothness, particularly in fast e-sport titles. For consoles, we stick to the standard limit of 120 Hz, but even so, the possibilities are truly extensive. The only minor criticism is slight ghosting that can sometimes be seen in dynamic scenes. Other than that, C69K / Q6C offers everything gamers expect from a television.
