Samsung Q7F vs TCL C6KS / C69KS / Q6CS

Unfortunately, the Samsung Q7F is not one of the bright televisions, and this directly affects the quality of HDR movies. The peak brightness of the panel is only about 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it hard to talk about any "wow effect" that usually accompanies us while watching such films. During testing movie scenes, the image simply looked dim, and brightness almost invariably hovered around the mentioned 250 nits. The worst performance was observed in shots with small, intensely glowing elements – the applied global dimming technique reacted very aggressively, dimming the entire screen to maintain the black effect. On the plus side, it is worth noting the presence of a QLED coating that expands the color palette. As a budget QLED model, the Q7F performs quite decently here: its DCI-P3 color coverage is about 93%, and BT.2020 reaches 70%. This means that colors, despite the low brightness, can look quite vivid and attractive.

And how does the issue of HDR look? Here the C6KS performs quite well and – as is becoming a recurring theme in this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must remember the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible black levels. It’s a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional micro-details that could cause grayness on the screen. Such is the nature of local dimming technology in this price range, and one must be aware of it. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the tagline of QLED technology. Thanks to this, the colors are saturated and vibrant – our measurements showed that the coverage of a wide color gamut reaches 92% here.

The factory color reproduction in the Samsung Q7F definitely isn't 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 noticeably lacking. The effects of this are very easy to see – white, instead of being neutral, takes on warm, almost slightly orange tones. Over time, this makes the entire image look somewhat unnatural, and bright areas of the scene can seem unrealistic. The problems become even more apparent in HDR content. The graphs show that the TV has significant errors in the Color Checker palette, which translates to visible inaccuracies in the real image. In practice, this means that colors 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 appear dimmed. As a result, the image seems flattened, and instead of helping to bring out details, contrast only highlights its own limitations. This is particularly frustrating in HDR materials, as every detail matters there. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the brightening or, conversely, suppresses elements that were meant to draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we get more of a simplification effect.

Unlike the more expensive C6K model, the tested C6KS does not have an option labeled Filmmaker Mode in the menu. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of color reproduction, the absence of this specific label makes virtually no difference. The best available Film/Cinema mode here offers nearly identical picture characteristics to the aforementioned Filmmaker mode in the more expensive model. So we get a very similar image, just under a different name. So if you were wondering whether paying extra for the C6K gives you better colors – the answer is: no, in both cases the base is the same and requires slight adjustments.

After professional calibration, we managed to bring the Q7F in order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colors appear natural, and errors in the color palette have dropped to values that are practically invisible to the eye. The gamma behaves excellently, and the only minor drawback is a slight brightening of smaller elements, which results from the lack of local dimming. For everyday TV watching or standard quality films, the Q7F performs surprisingly well.

It was much more difficult to tame HDR content. Despite adjusting the white balance, the television continues to manipulate brightness significantly, causing scenes to sometimes look unnatural – what was meant to be subtly darker can end up being overly brightened, and bright parts of the image sometimes appear dull. The final effect is better than in the factory settings, but it is evident that the design limitations of the Q7F do not allow for fully utilizing the potential of HDR materials.

Thanks to the white balance adjustment, the tendency of the C69KS to distort colors has been effectively reduced, leading to a very good final effect. After calibration, we won't see excessive warmth in SDR scenes or overly cool tones in HDR. However, it's worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, television programs, or materials from YouTube. It is much more difficult to evaluate the performance of the television in HDR. Analysis of the EOTF curve suggests correct behavior, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of color reproduction, but certain limitations arising from the operation of local dimming and the way it is controlled by the C69KS cannot be avoided, as we also saw in the C6K test.

Upscaling and digital image processing in the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older movies or terrestrial 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 looks rather unrefined. 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 remains. It's a bit disappointing because we could have expected more from a model that is aimed at users looking for a display for SDR content.

C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a significant amount of detail is preserved, and the algorithm adds a subtle "rounding" effect to sharp edges, making the image appear more cohesive. However, the smoothing of tonal transitions is lacking. The television practically cannot improve them, leaving the image in a somewhat raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

Motion blur and motion fluidity in the Q7F is probably the most budget-conscious element of this TV. The 60 Hz panel is noticeable, with blur being quite evident, especially in dynamic scenes, and it's rather difficult 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 tail, and the ball in a football match would leave trails behind it.

On the plus side, the presence of motion smoothing is commendable. It really makes a difference in movies - especially since most materials are recorded at 24 frames. Here we can decide for ourselves whether we prefer a more "cinematic" image, with the slight jerkiness characteristic of cinema, or a smoother, more "television-like" one. This actually works quite well and helps improve the viewing comfort for series or movies.

C69KS offers a simplified motion improvement panel in movies, allowing you to adjust the intensity of the effect using a slider. This makes it easy to match the smoothness to your own preferences. The possibility of using higher refresh rates is also a plus – even though the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p allows you to enable 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, but in practice, the image at these settings suffers from significant motion blur. The effect is noticeable enough that the overall experience feels simply mediocre and loses its appeal in everyday use.

Features for gamers in the Samsung Q7F is a topic that evokes quite a mix of emotions. On one hand, no reasonable person expected miracles here, as this is a 60 Hz television, and it was clear from the start that it wouldn't be equipment for extracting the maximum from consoles or PCs. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. At the outset, it’s quite decent. The automatic game mode (ALLM) works, so you don’t have to manually fiddle with the settings, the console itself switches the television to low-latency mode. In addition, we have Game Bar, which looks impressive and allows you to view some basic parameters without leaving the game. And this is where the good news ends.

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

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, a relevant icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the feature remained inactive and could not be activated in any way. It’s even more disappointing regarding HGiG; this option was actually available at the beginning, but after the software update, it completely disappeared, which is just unprofessional. Therefore, the Q7F is suitable only for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television that you buy with gaming in mind, and it’s better to be aware of that before making a purchase.

If we overlook the smearing and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything you can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a reasonably functioning HGiG. The TV can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings during gaming. As a result — despite a few limitations — the C69KS can be a truly successful screen for gamers.
