Panasonic W70A vs Samsung U8000F (VA)

HDR on the Panasonic W70A unfortunately does not impress. A brightness level of 250–300 nits is simply too low to feel the true magic of cinematic effects in dynamic, bright scenes. Images that should “explode” with light appear rather flat, and fine details in bright areas often get lost in the average luminance of the panel. On the plus side, the HDR effect is at least stable. The TV does not suffer from excessive brightening nor lose details with sudden scene changes. Everything is predictable and calm, though unfortunately lacking in impact. Another issue is the colour gamut coverage. The W70A is not equipped with an additional layer of quantum dots (often known as QLED), which is why the colours appear rather average. There is a lack of depth in reds, saturation in greens, and precision in reproducing subtle shades.

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.

The Panasonic W70A was tested in movie mode, which theoretically should guarantee the most natural image reproduction. Unfortunately, as is often the case with budget televisions, reality turned out to be far from ideal.

In HD (SDR) content, the white balance was significantly disrupted by an excess of red and a noticeable drop in blue tones. The result? The image had a distinctly warm, almost yellowish glow, which is clearly visible in the comparison photo. In the case of 4K HDR materials, the situation reversed. Here, the image became excessively cold and bluish, causing scenes to lose their naturalness and depth. The differences are visible even to the naked eye, especially in the bright areas of the image. The Colour Checker palette test confirmed our observations. Most colour samples did not hit their intended points, 'drifting' towards warmer shades in SDR and cooler ones in HDR. In terms of brightness characteristics, both gamma and the EOTF curve showed significant issues. The image tended to excessively brighten certain areas, disrupting the balance and leading to a loss of detail in both darker and brighter regions.

In summary – the factory colour reproduction settings in the Panasonic W70A leave much to be desired. The image is far from neutral, and errors in white balance and gamma mean that solid calibration is needed to extract the full potential from this television.

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.

Panasonic W70A, despite its limitations, gave us plenty of room to manoeuvre during calibration. Thanks to well-developed tools, we were able to achieve a much better white balance in both HD (SDR) and 4K HDR content. The issues with excessive red in SDR and overly cool images in HDR have disappeared. The gamma brightness characteristics have also been improved, now maintaining stability and not leading to excessive brightening or loss of detail in darker areas.

So where is the problem? Unfortunately, there are barriers that even professional calibration cannot overcome. Poor coverage of a wide colour gamut means the television cannot fully convey colours in HDR materials. There is a lack of saturation, and subtle colour transitions still appear somewhat “flattened.” Another limitation is the brightness management due to the IPS panel used. In a comparison photograph with an actress's face in colourful clothing, it is clearly visible how some shades are distinctly muted, and colours lose their depth and vibrancy.

Calibration has extracted from the W70A as much as it could. The image is now much more natural, and the factory setting errors have been effectively corrected. Unfortunately, the hardware limitations in the form of poor colour gamut coverage and an average panel mean that even after calibration, we are unable to achieve spectacular effects, especially in HDR content.

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.

We checked how the Panasonic W70A handles upscaling content that is lower quality than 4K, and I must admit that the TV performs quite decently in this regard. The feature responsible for smoothing tonal transitions is called "Zeroing Counter." The optimal setting turned out to be the Average option, which effectively smooths out colour gradation issues while not ruining the film grain. This is the setting we recommend for most users, as it provides a balance between enhancing the smoothness of transitions and maintaining the naturalness of the image.

When it comes to image scaling, the Panasonic W70A performed really well. The test chart with the model looked positive – details in her clothing were well reproduced, and the contours of her face maintained sharpness. In the background, we noticed a slight "jagginess" on thin branches, but these are details that only a very attentive eye will catch. However, it's worth noting a certain quirk of this model – the TV has a tendency to overscan, meaning it slightly crops the edges of the image. It’s not a very intense phenomenon, and for most users, it will be practically unnoticeable, but if we care about perfectly framing the shot, it's worth keeping this in mind.

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 Panasonic W70A is equipped with a 60 Hz panel, which immediately suggests that the TV is best suited for watching movies, series, or everyday television content. In more dynamic scenes, such as sports broadcasts or games, the limitations of the panel become more noticeable. However, it is worth noting the presence of a motion smoother called “Effect”, which offers three levels of adjustment – low, medium, and high.

Each setting allows you to adjust the smoothness of motion to your own preferences, minimizing the motion blur effect and improving the clarity of dynamic shots. In practice, the Medium setting seems to be the most universal – it offers better smoothness without the excessive “soap opera effect” that can look artificial in feature films. The High setting may work well for sports broadcasts, but in movies, it can disrupt the natural character of motion.

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.

The Panasonic W70A is a TV that is likely to suit casual gamers more than hardcore players. The 60 Hz refresh rate doesn't fully utilise the potential of next-gen consoles, especially in dynamic titles. The lack of HDMI 2.1 slightly limits its capabilities, but fortunately, it includes features like ALLM, which automatically switches to game mode, and VRR, which helps minimise screen tearing. It's also worth noting the support for Dolby Vision in games and HGiG, making HDR more predictable and looking solid. It's a pity, though, that it lacks Game Bar. This feature is now standard in many TVs and provides quick access to the most important settings for gamers. The W70A performs well for gaming, but it does have its limitations. It will do fine with more laid-back titles, but more demanding gamers may feel unsatisfied.

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.
