Panasonic W70A vs Samsung R85H / R86H

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 “burst” with light look rather flat, and fine details in bright areas often get lost in the average luminance of the panel. On the positive side, the HDR effect is at least stable. The television does not fall into excessive brightness or lose details during rapid scene changes. Everything is predictable and calm, although unfortunately rather unimpressive. Another issue is the colour gamut coverage. The W70A has not been equipped with an additional layer of quantum dots (often known as QLED), which means the colours appear rather mediocre. There is a lack of depth in reds, saturation in greens, and precision in reproducing subtle shades.

When it comes to brightness, the R85H performs really respectably. In most of our test scenes the TV reaches around 800 to 900 nits, and with larger bright elements it can exceed 1000 nits. These are not, of course, levels on a par with the pricier Mini-LEDs, but they are more than enough for watching films and TV shows in HDR, and the effect can already be quite noticeable. The problem reappears in more demanding scenes where there is a small bright element on a very dark background. Here the TV can significantly limit its brightness so as not to light up too large a portion of the screen. In our measurements such small highlights fell even to around 200 to 250 nits, so it is clear that a small number of zones combined with the particular behaviour of the algorithm has consequences here. Fortunately, this is not something that disturbs viewing all the time. In typical mixed HDR scenes the R85H looks good and can deliver appropriate image dynamics. It's just that with very small points of light you shouldn't expect an effect as strong as on TVs with many more zones or on OLEDs.

The Panasonic W70A was tested by us in movie mode, which theoretically should guarantee the most natural image reproduction. Unfortunately, as is often the case with budget TVs, the reality proved far from ideal.

In HD (SDR) content, the white balance was severely disrupted by an excess of red and a noticeable drop in blue tones. The effect? The image had a distinctly warm, almost yellowish glow, which is clearly visible in the comparison photo. In the case of 4K HDR material, 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. As for brightness characteristics, both gamma and the EOTF curve showed significant issues. The image tended to excessively brighten certain areas, disrupting balance and leading to a loss of detail in darker and lighter 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 a solid calibration is needed to extract the TV's full potential.

In Filmmaker mode our R85H sample performed acceptably in SDR, but a few things stood out immediately in the measurements. In the white balance red increased with rising brightness while blue decreased. As a result the brighter parts of the picture had a slightly too warm tint. Gamma only held to the target value at the start. It then gradually fell, which left most of the image a little too bright. The combination of these two effects also showed up in the colours, with errors growing particularly in the brighter and more saturated samples. It did not look bad, but for Filmmaker mode we had expected a bit more accuracy. Interestingly, in HDR our sample fared noticeably better. The white balance was much more even and, over most of the range, the individual components stayed close together. Only in the very brightest areas did red start to be lacking, causing white to shift subtly. The EOTF curve, by contrast, looked very good and followed the target luminance levels across almost the entire range. That does not mean HDR colours were perfect. The Colour Checker still showed some deviations, especially for some of the more saturated hues, but the errors were clearly smaller than in SDR.

Panasonic W70A, despite its limitations, provided us with considerable scope during calibration. Thanks to well-developed tools, we managed to achieve a significantly better white balance in both HD (SDR) and 4K HDR content. The issues with excess red in SDR and overly cool images in HDR have disappeared. The gamma brightness characteristic has also improved, maintaining stability and preventing 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 color gamut means that the television cannot fully reproduce colours in HDR material. There is a lack of saturation, and subtle colour transitions still appear somewhat "flattened." Another limitation is brightness management, which results from the applied IPS panel. In the comparative image with the actress's face in colourful clothing, it is clearly visible how some shades are noticeably muted, and colours lose their depth and vibrancy.

Calibration has extracted from the W70A as much as possible. The image is now significantly more natural, and the errors in the factory settings have been effectively corrected. Unfortunately, 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.

After calibration the R85H shows it has genuinely substantial capabilities in colour reproduction. It performed best in SDR, where the white balance could be brought almost perfectly into line and the gamma stays very close to the target value across most of the range. This also translated into very low errors on the Colour Checker, so there is really little to pick fault with. HDR also shows a clear improvement, although some things can no longer be corrected as well. At the highest brightness levels the character of the backlight begins to make itself felt and the individual components of the white balance start to drift apart. The same applies to the most saturated colours, which do not always land exactly where they should. Despite these limitations the overall image is much more accurate than with the factory settings, and the biggest difference is definitely seen in SDR. There is, however, one thing calibration cannot fix. With heavily saturated elements the colour can slightly bleed onto adjacent bright areas of the image. It is easiest to notice this on white, which can pick up a faint tint of a neighbouring colour. It does not appear in every scene, but when the material is demanding the effect can be visible. This is more a characteristic of the way the RGB backlight works than a matter of picture settings.

We checked how the Panasonic W70A performs when improving content of lower quality than 4K, and it must be said that in this regard, the television does quite respectably. The "Zeroing Counter" function is responsible for smoothing tonal transitions. The optimal setting turned out to be the Average option, which effectively smooths out issues with colour gradation 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 panel with a model was positively received – the details on her clothing were well reproduced, and the contours of her face retained clarity. In the background, we noticed slight "jaggies" on thin branches, but these are details that only a very keen eye would catch. However, it is worth noting a certain drawback of this model – the television tends to overscan, or slightly cropping the edges of the image. This is not a very intense phenomenon and will be practically unnoticeable for most users, but if we care about a perfect fit of the frame, it is worth keeping this in mind.

In the R85H image processing is handled by the Micro RGB AI Processor. The name is new, but when it comes to upscaling lower-quality material the TV’s behaviour is very similar to what Samsung has shown before. And that’s not a bad thing, because the manufacturer has dealt with this aspect quite well for years. Lower-resolution content is displayed cleanly, edges do not become excessively soft, and the TV does not try to artificially extract details at any cost. The result is simply well balanced, and with regular broadcasts or older recordings the R85H performs as you would expect from a Samsung in this class. There remains only a minor drawback in the form of overscan, which cannot be completely turned off at the lowest resolutions. A separate matter is the additional processing of weaker sources. The R85H can smooth posterisation and somewhat tidy up heavily compressed footage, but it is worth emphasising that it does this relatively aggressively. At stronger noise reduction settings it begins to remove not only compression artefacts but also fine details and the natural film grain. It is therefore best used only when the material truly needs it.

The Panasonic W70A is equipped with a 60 Hz panel, which immediately suggests that the television is best suited for watching films, series, or everyday TV 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 degrees of adjustment - low, medium, and high.

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

The R85H has a 144 Hz panel, so motion is really smooth here. Just bear in mind that the extra hertz above 120 are mainly used when connected to a PC, so in this category we don't treat them as any particular advantage. For films and TV, what's more important is that the panel is fast enough to provide access to an advanced motion-smoothing feature, "Motion Clarity", which lets you set motion anywhere from more film-like to very smooth. The panel's response time is a bit worse. Because it's a VA panel, fast-moving objects can leave a slight trail. On bright backgrounds this isn't very noticeable, but the darker the scene, the more pronounced the smearing becomes. This is a typical trait of this type of panel and it's easiest to notice in dark shots.

The Panasonic W70A is a television that is more suited to occasional gamers than to avid players. The 60 Hz panel does not allow for the full potential of next-generation consoles to be realised, especially in dynamic titles. The lack of HDMI 2.1 somewhat limits its capabilities, but fortunately, it features functions such as ALLM, which automatically switches to game mode, and VRR, which helps minimise screen tearing. It is worth noting the support for Dolby Vision in games and HGiG, which makes HDR more predictable and looks solid. It is just a shame that there is no Game Bar. This feature has become standard in many televisions and provides quick access to the most important settings for gamers. The W70A performs adequately for gaming, but it has its limitations. It will work well for calmer titles, but more demanding gamers may feel a lack of fulfilment.

Samsung has been steadily expanding its gaming features for several years, and the R85H really doesn't miss anything important here. The TV supports 4K at 120 Hz, VRR and ALLM, so we can easily take advantage of the PlayStation 5 or Xbox Series X. HGiG also works correctly, so with HDR properly set on the console, games retain the correct brightness and we don't unnecessarily lose detail in the brightest parts of the picture. The only major omission is Dolby Vision Gaming, which Samsung does not support on any of its TVs. The Game Bar is also very useful — a handy menu you can bring up without leaving the game. We can quickly check the frame rate, VRR status or change key picture settings. Samsung also adds a few less obvious features, such as the ability to change the aspect ratio and Game Motion Plus, which can further smooth games running at 30 or 60 frames per second. Of course this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting addition for some people.
