Samsung Q8F vs TCL P89K / TCL P8K

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.

The maximum brightness of the TCL P8K peaks at around 300 nits, although in real film scenes the television typically maintains closer to 250 nits. These are values that cannot be considered sufficient to achieve a true HDR effect – they are more aligned with a solid base for SDR content. Therefore, we won’t see spectacular flashes, bursts of light, or moments where the screen actually “blinds” as is the case with more expensive models. The image is consequently a bit flat, and the differences between light and shadow – more symbolic than realistic. Fortunately, TCL has a few aces up its sleeve that save the overall impression. One of these is the coverage of the DCI-P3 colour gamut at around 93-94%. Thanks to an additional QLED layer (PFS LED), colours gain depth and intensity, clearly surpassing standard LCD panels. As a result, while the typical “wow effect” associated with HDR brightness is lacking, the image itself can impress with its richness and vibrant tones, making the film scenes pulse with colour and not appear significantly washed out.

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.

In Filmmaker mode, the TCL P8K revealed certain imperfections in image reproduction from the start. We noticed that the TV had a tendency to slightly brighten scenes – its gamma was somewhat lowered, which made the image appear softly "washed out," lacking depth, as if the contrast had slipped out of control. This was most noticeable in HDR content, where the EOTF brightness curve clearly deviated from reference values. As a result, darker areas of the image looked too gloomy, and brighter ones did not always reach the correct level of luminance. The second noticeable issue was a slight blue overdrive – the TV stubbornly boosted this colour, causing some parts of the image, especially skin tones and reds, to have a slight purple tint. It is not a major flaw, but to a discerning eye – noticeable. Fortunately, most of these errors could be adjusted during calibration. You can see the results of this calibration in the charts and photos below.

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 calibration, the TCL P8K revealed a completely different side. It managed to achieve nearly perfect, even reference-level colour reproduction for both SDR and HDR content. The screen no longer had a tendency towards a cool tint, and the white balance was perfectly aligned. The gamma values for SDR materials finally look as they should – the image has the right depth and no longer appears washed out. The only concern that can still be raised about the P8K pertains to its "Chinese" traits, known from most TCL models. The TV still likes to manipulate saturation in HDR content in its own way – sometimes it gently boosts it, other times it smooths it out, making the effect not always fully predictable. Nevertheless, after calibration, the colours look stunning, and their accuracy is truly impressive. In most cases, measurement errors dropped below values of 1–2, which is a performance that much more expensive models would not be ashamed of.

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.

The TCL P8K performs somewhat weaker when it comes to the fluidity of tonal transitions in lower quality materials. The television does offer a feature to smooth out unwanted bands, but its effectiveness leaves a lot to be desired. Even at the highest setting, it's hard to speak of a real improvement—at times, the effect is even opposite to what was intended, as the feature can introduce small artifacts and unnatural blurring on the screen.

On the other hand, the upscaling, which involves scaling the image to 4K resolution, looks definitely better. The P8K handles this task surprisingly well—HD content, and even SD, is enhanced in an aesthetically pleasing way without excessive loss of sharpness. There are indeed slight “hard” edges typical of this class of equipment, but this can be easily adjusted using the sharpness slider according to personal preferences. The final effect is more than satisfying, especially considering the price range this model is in.

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 P8K is one of the cheapest televisions offering a 144 Hz refresh rate, which in itself is a significant advantage in this price segment. Thanks to the fast panel, this model can confidently be recommended to both sports fans and gamers – the image is smooth, and the movements of the ball or dynamic actions look natural. However, this does not mean that the P8K is suitable only for sports. On the contrary – it can also maintain the right dynamics in movies without introducing an artificial 'theatrical' effect, as long as the settings are adjusted thoughtfully. The television is equipped with a motion smoother called 'Motion Clarity', which features two sliders: blur reduction and flicker reduction. The first is responsible for smoothing the image by generating additional frames, which increases fluidity but can cause a slight soap opera effect. The second, on the other hand, reduces flicker and improves sharpness in motion, although it may slightly dim the screen. Properly adjusting these two parameters allows for a truly good balance between natural motion and fluidity. The 60 Hz screen is good for dynamic content, though more discerning users will notice that it is not a top-tier panel in terms of motion clarity.

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.

Although the TCL P8K is a budget television, it absolutely cannot be said that it is unsuitable for gaming. On the contrary – this screen can pleasantly surprise any gamer. On board, we find two HDMI 2.1 ports, which allow us to effortlessly send a 4K image at 120 Hz. If someone plays on PC, they will also be pleased to know that the television can operate even with a refresh rate of 240 Hz at a lower resolution – a small thing, but it’s appreciated. Additionally, there is a full set of gaming-specific features: automatic game mode, a Game Bar with quick parameter previews, VRR, HGiG, and support for Dolby Vision in games. All of this makes gaming on the P8K a truly enjoyable experience – the image is smooth, the response is quick, and the television works well with next-gen consoles. The TCL P8K shows that a cheap screen doesn't have to mean giving up on fun. Definitely not when it comes to gaming.
