Panasonic Z85A vs SAMSUNG QN80F

The Panasonic Z85A is an OLED television, so you can immediately expect excellent effects in films. And indeed – our tests showed that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result, performing well in most demanding HDR scenes, allowing viewers to enjoy a dynamic and detailed picture. However, like every OLED, the Z85A also has its limits. In very bright scenes that fill the entire screen – like the final sequence from the movie The Meg – the television reduces brightness to around 400 nits. This is standard behaviour for this technology, so if someone plans to watch films in a heavily sunlit living room, it is worth keeping this in mind. The coverage of the DCI-P3 colour gamut at 98% also deserves high praise. This allows the television to reproduce a wide range of colours that stand out with vibrancy and depth, while details in HDR scenes are sharp and precise. In short – the Panasonic Z85A delivers a solid HDR effect that will satisfy any film enthusiast.

QN80F is quite a bright screen – in synthetic tests, it reached nearly 1000 nits, which allows for reasonable expectations of HDR content. And indeed, in many scenes, the TV can truly shine. Sequences with a lot of light – like shots from the movie Life of Pi or wide, bright surfaces in The Meg – look impressive. Brightness stays around 700 nits, which provides a solid effect, enough to feel the true "HDR magic." Unfortunately, not every scene looks this good. In content with small, bright details on a dark background, like in Sicario 2, the TV can struggle – it can significantly dim individual elements, sometimes to the point where they disappear from the image. This is a result of the limited number of dimming zones, forcing the device into compromises: either stick to inky blacks or sacrifice some detail. QN80F usually chooses the former. As a consolation, it offers quite decent coverage of a wide color palette – DCI-P3 at 93%. It's not the highest score on the market, but it's more than enough for most content on streaming platforms.

The Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It's rare for a TV straight out of the box to be so well calibrated, and the unit we had the opportunity to test truly impressed us.

However, there were some minor shortcomings. In the SDR signal, we noticed a slight deficit of red and blue, which made the picture appear cooler than it should have been. This is particularly evident in the comparison image. In contrast, with 4K HDR material, the situation was the opposite – the surplus of red made the image seem warmer than intended by the creators. In terms of brightness characteristics (gamma) and maintaining an appropriate EOTF curve, it's hard to find faults. There are slight deviations, but they are so minimal that the average viewer is unlikely to notice them.

It's also worth highlighting that our observations relate to a specific unit of the TV. Two identical models may differ from each other due to natural production variances. Nevertheless, the piece we had in hand looks really solid and deserves praise. Now it's time for our calibration – we'll see if we can squeeze even more out of this screen!

We always test TVs in the best available factory mode – for the Samsung QN80F, this is the Filmmaker mode, and indeed, it provides the settings closest to the creators' intentions. However, this doesn’t mean everything looks perfect. In SDR content, the biggest issue was an unbalanced white balance – slight deficiencies in green and a noticeable excess of red led to noticeable colour errors, and one could say the screen had a pinkish hue. This was clearly visible in the colour checker test, where colours “escaped” outside their target fields – to such an extent that a sensitive viewer's eye could catch it even without the help of a meter.

In HDR content, the white balance was much better, but another issue arose – brightness management. The EOTF curve caused an overly bright image most of the time, which affected the perception of contrast and made the screen slightly “flicker” during dynamic changes in light. We’ve already discussed this in the paragraphs about black levels and HDR. Fortunately, Samsung offers users plenty of options. The QN80F features a rich set of calibration options, including a 20-point white balance – which is why we decided to check what this TV is really capable of after a proper calibration.

The Panasonic Z85A offers truly wide-ranging capabilities when it comes to picture settings, so we eagerly set about calibrating it. Although we mainly focused on adjusting the white balance, the final effect exceeded our expectations. Both HD and 4K HDR content now showcases nearly perfect colour reproduction, with minimal errors that are hard to catch with the naked eye. Well-calibrated TVs are a rarity, and we must admit – it’s truly satisfying. While the gamma and EOTF curve didn't require drastic adjustments, we managed to further stabilise their characteristics across the entire brightness scale. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The picture is precise, the colours are natural, and every scene looks exactly as the director intended.

After conducting a thorough calibration, it was possible to bring most image parameters to a really good level. The white balance in both SDR and HDR presents itself almost perfectly – the image is natural, neutral, and free from the previously noticeable redness. Colours have gained depth, and the overall visual experience has become more pleasant and cohesive. It was also possible to partially manage brightness, which in the factory version could cause issues. The EOTF chart shows that the television performs much better with brightness after calibration – there is no longer excessive dimming of certain elements. In films, it can still be noticed that the QN80F has a tendency to slightly brighten the smallest bright details – this is already a consequence of the device's construction and the limited number of dimming zones. In short: not everything can be overcome, but what was possible has been improved. After calibration, the QN80F makes a really good impression, looking simply more mature and professional.

Now that we know how the Panasonic Z85A handles tonal transitions in 4K material, it’s time to take a look at its "Gradation Smoothing" function. It works, but unfortunately not entirely effectively. Regardless of the chosen value – whether it’s low, medium, or high level – we couldn’t achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this function to an intermediate level. While this may slightly blur fine details, at least it avoids the problem of losing film grain, which can be crucial for many viewers when watching classic productions.

When it comes to image scaling, the TV performs quite well. It’s noticeable that the image is slightly sharpened, and thin lines can sometimes appear a bit jagged. However, this is standard for most TVs, and fortunately, it can be adjusted using the sharpness slider. This gives us full control – we can achieve a more vivid, blurred image or a clearer one, although it may appear more "harsh" and artificially sharp. It all depends on the user's preferences and the type of content we’re watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution material.

If you notice strange colour transitions or unwanted artefacts while watching lower quality materials – for example from YouTube – it's worth checking the settings and enabling the noise reduction feature. In our opinion, the best setting is at the 'medium' level – it effectively smooths out problematic colour transitions without overly blurring the entire image. However, it's important to know one thing: this option tends to remove film grain. If someone values preserving that effect (e.g., in older films), it's better to simply turn it off – regardless of the level, the grain always disappears.

Regarding resolution scaling (also known as upscaling), Samsung – as usual – performs very well in this area. The QN80F doesn't quite match the top models costing tens of thousands, but for its price class, it performs impressively. Materials of very poor quality (e.g., from SD television or older video files) are noticeably improved and look surprisingly decent. The only noticeable downside is the typical Samsung issue with overscan – which is a slight cropping of the image edges at very low resolutions, such as 576p.

The Panasonic Z85A features a 120 Hz panel, which will surely please both gamers and sports fans. Sure, it’s not 144 Hz like some gaming TVs, but in practice, the difference is really hard to notice. In games, the picture is stable and sharp, and during fast action, there’s no sign of any blurring. The same goes for sports – a player’s quick run or a car’s dynamic maneuver looks smooth and natural. The TV also has an “Intelligent Frame Creation” feature, which is a motion smoother. There are two sliders here – one controls motion blur reduction, while the other adjusts motion smoothness. With these, you can tailor the picture to your own preferences – whether you prefer a more cinematic effect with gentle transitions between frames or a maximally smooth image ideal for watching sport.

QN80F is truly a “fast” TV. The panel used offers a refresh rate of up to 144 Hz, which in practice means that the screen keeps up with the action – whether we’re watching a movie, playing games, or browsing dynamic content online. The image doesn’t stutter, isn’t overly blurred, and everything simply looks smooth and pleasing to the eye. Of course, the manufacturer hasn’t forgotten about cinema fans – in the settings, we find an option to adjust motion smoothness, allowing us to tailor the effect to our own preferences. You can leave a more “frame-y” look (for those who enjoy the classic film vibe) or crank up the smoothness to a higher level to achieve a theatrical smoothing effect. Importantly, the choice is ours. Watching movies and playing on the QN80F is just plain fun.

Panasonic is mainly associated with home cinema televisions, but the Z85A shows that it can also step into the gaming world with a truly strong punch. It's a device that can easily be called a gaming beast – it has everything needed for comfortable gameplay.

Even though it has only two HDMI 2.1 ports, both operate at full bandwidth, so we can easily connect both a next-gen console and a gaming PC. All the key features are supported: ALLM automatically switches the television into game mode, VRR provides smooth visuals without stuttering and tearing, and with properly implemented HGIG and Dolby Vision, HDR games look really good – colours are vivid, details are sharp, and dark scenes are clear. We also find a Game Bar in the form of a transparent, circular menu. It may not look as impressive as the competition's, but it's intuitive and includes all the most important settings we’d want at hand during gameplay.

In summary – the Panasonic Z85A is a device that truly surprises with its gaming capabilities. It's a television where both console gamers and PC gamers will feel at home. It's smooth, dynamic, and just good.

Samsung QN80F is a television that delivers on almost every front when it comes to gaming. It features a 144 Hz panel, four fully-fledged HDMI 2.1 ports, support for gamers with variable refresh rate (VRR), automatic game mode (ALLM), and even one of the best-designed gamebars on the market. The icing on the cake is the motion smoother which – uniquely in the world – works in games without significantly increasing input lag. Sounds like an almost perfect gaming TV? And indeed, it is almost that.

[UPDATE] We have updated our Samsung TV tests from the 2025 model year due to the release of firmware version 1131, which restored the crucial gaming feature HGiG.

As usual, Samsung doesn’t support Dolby Vision in games, but that’s no longer surprising. However, what is much more surprising is that... the HGIG feature has disappeared – meaning the system that allows the console (e.g., PlayStation 5 or Xbox Series X) to accurately match HDR tone mapping to the capabilities of the television. In the latest firmware update for the 2025 models, this option simply vanished. It looks more like a bug than a deliberate move, but it must be honestly noted that at the time of writing the review, the HGIG feature is simply absent.

And it’s precisely because of this one absence that the QN80F goes from being an almost perfect gaming television to a “nearly” perfect device. What a shame – because everything else indicated that Samsung could once again set the bar very high in this generation.
