Samsung U8000F (VA) vs TCL C6KS / C69KS / Q6CS

While the U8000F with its VA panel can still be praised for decent blacks, there are no such accolades when it comes to brightness—particularly in HDR scenes. The television only achieves a maximum of just under 250 nits, which is simply too low to talk about any impressive light effects. Bright elements appear washed out, and scenes that should shine look rather flat. An interesting situation occurred during our testing of a scene from the movie Sicario 2— the screen noticeably darkened, as if the television was trying to hide its limitations in displaying blacks. One might get the impression that the device artificially darkens the image to improve contrast, but in practice, the effect doesn't make much difference, apart from the fact that we see less on the screen. Additionally, there’s the issue of colours—the U8000F doesn’t support a wide colour gamut, so one shouldn’t expect vibrant, saturated hues known from better models. The HDR image here resembles a slightly brightened SDR and... maybe that’s not such a bad thing. For this model, it’s not worth expecting a cinematic experience—better to treat HDR as a modest addition.

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in 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, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92%.

Samsung U8000F has been tested by us in the best picture mode it offers out of the box – that is, Filmmaker Mode. This profile is supposed to theoretically provide a neutral, cinematic image, free of unnecessary enhancements and artificial beautifications. In the case of SDR content – mainly in HD or SD resolution – the television already presented itself surprisingly reasonably right out of the box. The only noticeable imperfection was brightness management. The gamma chart showed some deviations – slight brightening or dimming of certain tones – but in practice, this did not significantly affect the viewing experience. For a television in this segment, it performs quite well.

However, the situation in HDR mode looks significantly weaker. Although white balance was still acceptable, colour errors were very evident. In the Color Checker test, almost every sample was outside the target point, and the image itself appeared unnatural – colours were skewed, sometimes too cool, and at other times simply dull and lifeless. The main issue lies in hardware limitations – the U8000F does not support the wide colour gamut of DCI-P3, so it is physically unable to reproduce the colours that the HDR standard intends. Unfortunately, this is evident in almost every more demanding scene.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture profile to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K would give you better colours – the answer is: no, in both cases the base is the same and requires slight adjustments.

Right out of the box, the U8000F offered a pretty decent picture in SDR for its price range. We managed to tweak it a bit further – we reduced a slight purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the TV still has a tendency to overly brighten the brightest details – the gamma chart shows a clear break that cannot be fully corrected.

On the other hand, in HDR mode, it’s noticeably weaker. It's hard to talk about any significant improvement – despite attempts to fine-tune the settings, the picture still presents considerable colour errors. A Delta E exceeding 7 indicates noticeable deviations that we couldn’t effectively reduce. Unfortunately, this is a limitation of the construction itself – the U8000F simply wasn't designed for serious HDR. In daily SDR viewing, it performs quite well, but for HDR content... it’s best not to have overly high expectations.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, 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 colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed in the C6K test.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup. This year’s model is equipped with a feature that improves the smoothness of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but still – it can be confidently said that it works effectively. However, not everything has gone perfectly. The U8000F has noticeable issues with slight image stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must be prepared for the image to look slightly “choppy”.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

The Samsung U8000F comes with a 60 Hz panel, so right from the start, it's clear that you can't expect miracles. It's simply the standard in this class – sufficient for everyday viewing, but without any fireworks. The TV offers one motion smoothing slider – a function called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in films. Higher settings provide a more "theatrical" and smoothed effect, while lower settings maintain the original character of the film with a slight 24p effect. Interestingly, there is the "LED Clear Motion" feature, or BFI mode – which inserts black frames between the frames of the image to improve motion sharpness. However, in practice, the screen flickers significantly when this is activated, and it's best to treat this as more of an experiment rather than something that genuinely improves the gaming experience.

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

[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.

Samsung U8000F offers a basic set of features for gamers, which can still prove sufficient for less demanding users. Here we have an automatic gaming mode – when a game is launched on the console, the TV switches to low-latency mode by itself, significantly improving response time. We also find the VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the 'tearing' effect on the screen – as long as we stay within this range.

Unfortunately, that's about it when it comes to advantages. Add-ons like Game Bar or higher refresh rates are reserved for higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust the HDR image to the intentions of game developers. Unfortunately – despite this feature appearing in advertising brochures and store materials – its setup on the Xbox console turned out, in practice, to be... impossible.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.
