Samsung QLED Q80D vs Panasonic W85

In the context of HDR, the Samsung Q80D television, as expected, achieves very positive brightness results in the tested movie scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing for a great juiciness of the image. Such results enable the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g., the 4th test screen from the film Sicario 2), a noticeable drop in brightness is observed, which is caused by the large size of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements on a dark background. At that point, we may experience an undesired lack of brightness, and the HDR effect resembles that of SDR.

Unfortunately, we don't have good news here. The Panasonic W85B is quite a dark television – its peak brightness doesn't exceed 300 nits, making it hard to talk about any real HDR effect. In practice, this means that scenes which can 'shine' and impress on other screens simply look like regular SDR with a slight colour boost here. Our measurements and film tests confirmed this – regardless of the content, the W85B won't draw anything more from HDR. So if someone is looking for a television specifically for HDR, it's better to look at other models. On a positive note, the W85B does quite well in terms of colours. It's a QLED television, so its colour gamut coverage is wide, and most films and series look natural, without a noticeable 'faded' effect. The colours are saturated, so in everyday viewing, there's no feeling that something is seriously off.

In "Filmmaker" mode, which is the best choice right out of the box, the Samsung Q80D television shows solid colour reproduction. For SDR content, a noticeable drop at the start of the gamma curve suggests that details in dark scenes may be less clear, affecting the overall viewing experience. Regarding white balance in SDR content, while generally correct, significant drops in blue at screen coverage above 70% can result in less natural shades in both bright and dark scenes. Users may notice that some blue elements in the image may appear less vibrant, and the overall colour will have a warmer hue.

In HDR content, the EOTF curve being above the reference line for most of the time indicates that the television may struggle to accurately reproduce brightness and details in the brighter parts of the image, which can be detrimental for the viewer. It is also worth noting the significant drop at the start of this chart, indicating that the television has difficulty reproducing brightness in the darker parts of the image, as seen in the contrast and black test, where several scenes were unable to show the full capabilities of the television’s brightness. In terms of its white balance, the initially good performance on the graph is promising, but the steep decline in red, coupled with a significant increase in blue, can lead to inaccuracies in reproducing some skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

Testing the Panasonic W85B, we obviously started with the Filmmaker mode, as it's the gold standard for watching content "the way the director intended." The problem is that this TV is quite far from those intentions. The biggest issue turned out to be an excess of red – both in SDR and HDR. The image often looked too warm because of this, and in some scenes, it was almost "on fire." Added to this is the issue of brightness management. When we looked at the gamma and EOTF charts, it was clear as day that in most scenes, the TV brightens the image more than it should. The effect was easy to predict. Details can get lost, leading to flattening and clipping across the entire screen. We obviously know how to fix this, but to be fair, it does require a lot of calibration work. Out of the box, the W85B doesn't produce an image close to reference quality – it's more of a TV that, without professional adjustments, will always interpret colours and brightness a bit "in its own way." Unfortunately, this is to the detriment of the viewer.

The movie mode after calibration looks significantly better than the one you see right out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Color Management System). Both in HDR and SDR mode, white balance has improved significantly, although there are slight errors at the end of the graph for HDR content. Contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve on the television appears to be at an ideal level at first glance. However, when we dig a bit deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. You could even say that the television is "cheating" when playing film material. Such a situation, where the EOTF curve is above the reference line, causes the screen – although it may appear brighter, which some users might find appealing – to lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

Fortunately, calibration made a significant difference for the Panasonic W85B, especially for SDR content. Here, the improvement was quite evident – we managed to even out the white balance and reasonably tame the TV's tendency to overly brighten the entire image. The picture became more coherent and the colours gained the naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has noticeable issues with green saturation, but overall, we rate the post-calibration effect in SDR quite positively. The situation with HDR is a bit different. Here too, we managed to reduce the tendency to warm up the entire scene, so the image performed definitely better than in the factory settings. However, there is still the same problem we mentioned earlier – the TV interprets the image too strongly "in its own way" and brightens the whole screen. And the lack of local dimming only exacerbates this effect. In summary, briefly, in SDR content, the W85B performs really well after calibration and is perfectly suitable for everyday viewing. However, in HDR, even after adjustments, it is still difficult to unambiguously recommend it for more serious viewing.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle gradation, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes it to blur elements that shouldn't be smoothed, such as film grain. For those who prioritise a plastic, smooth image, this can be seen as a significant advantage, especially with lower-quality content.

In terms of image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing the viewing comfort. The TV handles the conversion of lower-resolution materials, improving their quality and details. For example, in the attached image featuring a model, there are no visible artefacts or excessive fraying of branches, which demonstrates advanced image processing technology.

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or clear outlines. However, the situation is worse with lower resolution materials. This is where the TV has the biggest problem with "beautifying" the image. The lack of any menu option to improve gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with colour blending.

Fortunately, upscaling, or enhancing the quality of lower resolution content, performs much better. This is definitely a strong point of this model – the image is scaled cleanly and in detail, and the TV handles this better than one might expect from such an inexpensive setup. This is thanks to the HCX processor, which Panasonic has been developing for years, and it shows that even in the lower series, it can do a good job.

The Samsung Q80D television stands out very positively in terms of motion fluidity and minimizing blur, mainly due to the 120Hz panel and above-average panel response time. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustments in a 10-step scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of fast-moving objects. In the UFO test, there is no blurring behind the moving object, and the image is not cloned forward, indicating the absence of an overshoot effect.

At first glance, everything looks good – the Panasonic W85B has a 120 Hz panel and even a 144 Hz mode, so it seems like it should handle smooth motion really well. The problem starts when we delve into the settings. The options for improving fluidity are supposedly present in the menu, but in practice… they don't change anything. No matter what we choose, the image looks the same. On top of that, there’s a lack of BFI, or black frame insertion, which in many TVs helps sharpen motion. And suddenly, it turns out that despite the strong panel, the W85B doesn’t give us any real tools to adjust that motion to our needs. It’s only good when the source itself operates at a higher frequency – for example, games at 120 Hz. But when it comes to movies or sports, we just have to accept what the TV shows us because there’s nothing more that can be done about it.

The Samsung Q80D TV is a real gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz at 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The TV also supports HGIG (HDR Gaming Interest Group), enabling optimal HDR content display in games. Additionally, it comes with a Game Bar, providing quick access to gaming settings. Users with Nvidia graphics cards will also be pleased with the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision, which may be disappointing for users looking for that HDR format. It's also worth mentioning that since 2022, thanks to the collaboration with Microsoft, Samsung TVs offer the Xbox Game Pass app, allowing for cloud gaming. This is an added bonus for gamers who want to take advantage of a wide library of games without needing a console.

On paper, the Panasonic W85B looks really solid. It has two full HDMI 2.1 ports, support for ALLM, variable refresh rates, Dolby Vision in games, and of course, a high refresh rate for the panel itself. Additionally, there's the characteristic Panasonic game bar, which allows you to view key parameters with a single click and quickly change them if needed. It sounds great, but the problem arises when we enable HDR. Here, the W85B really struggles because the implementation of HGiG is practically nonexistent – the TV poorly manages brightness, and instead of faithful images, we get scenes that are too bright, sometimes even blown out. The solution? The simplest one – turn off HDR in the console settings and keep everything in SDR. And here it gets really interesting, because in this scenario, the W85B shows its better side. Low input lag, high smoothness thanks to 120 Hz – all of this makes gaming look phenomenal. Yes, HDR can be skipped, but if responsiveness and smooth gameplay are the priorities, the W85B provides plenty of fun.
