Compare: Samsung QLED Q70D / Q74D / Q77D vs Panasonic Z85A

Samsung Q70D performed in the test just as it should for its category – very well. The strongest points of the television are undoubtedly its efficiency when using a console and the colour reproduction after undergoing the calibration process. The former will certainly not allow gamers to remain indifferent to the range of benefits that Samsung Q70D can offer, and there are indeed many, including this almost exclusive feature for the manufacturer’s units – the ability to smooth out gameplay while maintaining a reasonable input lag, which allows titles running at 30 fps to perform like those at native 60 frames per second. In the context of gaming, one cannot forget the well-implemented HGIG mode, which, when correctly set up, is on par with games using Dolby Vision. One should also not overlook the ease of pairing the television with the Canal+ decoder, which is not such an obvious advantage, but we know that many people struggle with this issue. Staying on the topic of television, it must be acknowledged that the Samsung Q70D offers very good brightness in SDR materials for its price range, making daytime viewing more than comfortable. A downside for the tested television has to be the lack of Dolby Vision, which would have greatly enhanced the maximum brightness of the Samsung Q70D. One should also not overlook the construction flaws of the device, which may (though not necessarily) lead to light bleed, which can be noticed in dark conditions on less bright scenes. What cannot be taken away from Samsung Q70D is the fact that it features one of the better motion smoothing technologies in its price range, which works excellently in the context of sports events or fast-paced action scenes. The system that operates the television runs very smoothly, and the only complaint one might have is the lack of the Tidal app. In summary, the Samsung Q70D is a good continuation of the manufacturer's seventh series, which year after year gains – both in quality and popularity.

The Panasonic Z85A is the entry-level OLED model from the Japanese manufacturer, which fully utilises the potential of its panel. Thanks to OLED technology, we can expect phenomenal picture quality at the highest resolution – perfect blacks, excellent contrast, and superb HDR effects, especially after professional calibration. Additionally, it supports a full range of HDR formats, so we can easily choose a film in the best possible quality. Although Panasonic is usually associated with home cinema equipment, the Z85A performs just as well with sports and games. A 120 Hz panel, support for VRR, ALLM, and even functioning Dolby Vision in games guarantee smooth gameplay without any motion blur. The sound also deserves praise – although we won't find an impressive soundbar like in the model Z95A, it is still quite pleasant and has noticeable bass. Downsides? Primarily the Amazon Fire TV – an operating system that still has growing pains. Many popular applications are missing, and some functions are unavailable or poorly translated (e.g. lack of support for external subtitles). Another issue is the not very high brightness, typical of older WOLED panels – this may be a problem in a brightly lit room. Despite these shortcomings, the Panasonic Z85A is a great option for cinema enthusiasts and gamers looking for a versatile television with exceptional picture quality and solid sound. If we can overlook certain limitations of the system and the not-so-high brightness, the Z85A still has a lot to offer. However, if complete user comfort and a richer application ecosystem are crucial for us, then it is worth considering other OLED televisions from competitors as well.

Samsung Q70D and its related models, such as Q77D and Q74D, utilise a VA panel, which in itself should provide decent contrast. Typically, it is several times higher than in IPS/ADS screens that are not equipped with an advanced local dimming system. The contrast results, as you can see, are quite varied, which is caused by the non-uniformity of the panel. Therefore, at times we can achieve good contrast, whereas at other times it is significantly degraded, but generally fairly consistent, not counting light leakage. Let’s take a look at the film scenes we prepared from the films "Oblivion" and "Revenant". As we can see, in the first one, the lights are well separated from each other, which is a positive phenomenon, as visibility of details in the whites in further tests should be equally good. What stands out the most here is the unusual over-sharpening of smoke visible under the light and the navy black in the background. In the frame from the second film, the first thing that stands out is the uneven backlighting of our scene. It was quite significant and heavily affected the perceived image. Nevertheless, the details in the film were well visible.

The Panasonic Z85A uses a WOLED panel, which means one thing – perfect black and infinite contrast. Each pixel lights up and dims independently, so there is no question of any streaks or glow around bright objects on the screen. Even in the most demanding scenes, the image looks simply exemplary. There is no room for compromise in this regard, which is still present even in the most expensive LCD televisions. Here, Panasonic shines, utilising organic technology provided by LG Displays, and does so in truly impressive style.

The brightness that the Samsung Q70D can offer is at a fairly average level, although it cannot be said that the HDR effect will be unnoticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR materials. As was the case in the paragraph about contrast and black levels, this time we can observe that the first scene, featuring a bright sun and a dark foreground, possesses the lowest luminance among the measured ones. The result, which can be considered very good for this price range and class of display, is the latter. In a scene where we see a large light source filling a significant part of the frame, the brightness of the television is at its highest, reaching nearly 500 nits. It is worth noting the quite low coverage of the wide DCI-P3 colour gamut, which occasionally results in noticeable gaps in the colour palette. Additionally, users can enjoy rich colours and high precision in shade reproduction, making movie screenings a special experience. It is also worth noting that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

The Panasonic Z85A is an OLED television, so one can immediately expect great effects in films. And indeed – our tests have shown that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result that performs well in most demanding HDR scenes, allowing viewers to enjoy a dynamic and detail-rich image. However, like any OLED, the Z85A has its limits. In very bright scenes covering the entire screen – such as the final sequence from the film 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 brightly sunlit living room, it is worth keeping this in mind. The coverage of the DCI-P3 colour gamut at 98% also deserves high praise. Thanks to this, the television reproduces a wide range of colours that stand out with vibrancy and depth, and details in HDR scenes are sharp and precise. In short – the Panasonic Z85A delivers a solid HDR effect that will satisfy any film enthusiast.

The best factory mode on the Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before calibration, it had several flaws that effectively prevented it from conveying the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green. As a result, there was a characteristic yellow tint on the image, causing white to appear yellowed and resulting in skin tones that were noticeably too warm. The lowered gamma in standard colour gamut materials resulted in a significant drop in contrast, which was already not the highest. This caused detail in the blacks to be accentuated but also led to overexposure in brighter scenes. The EOTF curve, in this case, proved to be much better and only brightened those scenes with relatively low luminance. This was perfectly evident in the section where we measured the television's maximum brightness in HDR materials. At that point, the frame from the film "Billy Lynn" was unnaturally bright and lacking in depth.

The Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It is rare for a television to be so well tuned straight out of the box, and the unit we had the opportunity to test really surprised us positively.

However, there were a few minor shortcomings. In the SDR signal, we noticed a slight deficit of red and blue, which resulted in the image having a cooler hue than it should have. This is especially noticeable in the comparative photo. Conversely, in 4K HDR content, the situation was the opposite – an excess of red made the image appear warmer than the creators intended. In terms of brightness characteristics (gamma) and the maintenance of the appropriate EOTF curve, it's hard to find fault. There are slight deviations, but they are so minimal that the average viewer is unlikely to notice them.

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

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, including 2-point and 20-point grey scale adjustment as well as advanced CMS. This allowed us to significantly improve the quality of SDR and HDR content. The vast majority of errors have been corrected, and the image that the Samsung Q70D now generates is definitely closer to the reference. Higher deltaE errors in wide dynamic range content are primarily due to the display's insufficient luminance.

The Panasonic Z85A offers truly wide possibilities when it comes to image settings, so we enthusiastically set about calibration. Although we mainly focused on correcting the white balance, the final result exceeded our expectations. Both HD and 4K HDR content now display nearly perfect colour reproduction, with minimal errors that are hard to catch with the naked eye. Well-calibrated televisions are a rarity, and we must admit – it is truly gratifying. Although the gamma and EOTF curve did not require drastic adjustments, it was possible to further stabilise their characteristics across the entire brightness range. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The image is precise, the colours are natural, and every scene looks exactly as the director intended.

Considering how important lighting is in films and series, the overlapping structures and the fluidity of tonal transitions constitute an extremely significant element in assessing the quality of the image. The colour grading in the tested television stands at a fairly decent level. It cannot be said to be outstanding, but it is also not bad. We assess it as adequate. Brighter scenes perform best here, showing the least amount of stuttering. In scenes recorded in darker settings, slight deficiencies in grading can already be noticed, although this is not an issue that would cause discomfort while watching. This may be disrupted by the bleed of the backlighting, which is clearly visible in the last image.

The Panasonic Z85A handles the smoothness of tonal transitions really well. Colours blend together naturally, without noticeable artefacts or visible banding. However, in brighter scenes, such as the opening sequence in the film Kingsman, minor imperfections can be discerned. This is typical of WOLED panels, which have their limitations compared to Samsung Display's QD-OLED designs due to the use of white sub-pixels. The differences are not colossal, but a trained eye will pick them up, especially in more demanding scenes with subtle colour gradients. Despite these minor reservations, the Z85A offers a level that will satisfy the overwhelming majority of users. Tonal transitions are smooth, and the image maintains consistency even in complex scenes. This is a solid result, which in practice will rarely be a hindrance during everyday viewing of films or series.

The function responsible for improving gradation has been named "Noise Reduction" in the menu. As we have confirmed, it is worth enabling, as it has a positive effect on tonal transitions. More importantly, it does not negatively affect the film grain or the fine details, which the competition sometimes "blesses" us with.

The image scaling on Samsung Q70D should be rated as average. The manufacturer does not intend to artificially sharpen the image, but rather to leave it naturally softened.

Now that we know how the Panasonic Z85A performs with tonal transitions in 4K content, it’s time to take a look at its "Gradation Smoothing" feature. It works, but unfortunately not entirely effectively. Regardless of the chosen value – whether it’s low, medium, or high – we were unable to achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this feature to an intermediate level. Although it may slightly blur fine details, at least the issue of film grain loss does not occur, which for many viewers can be crucial when watching classic productions.

As for image scaling, the television performs quite well. It’s noticeable that the image is slightly sharpened, and slim lines may at times appear a bit jagged. However, this is standard in most TVs, and fortunately, it can be adjusted using the sharpness slider. This gives us complete control – we can achieve a more plastic, blurred image or a clearer one, although it may be more “harsh” and artificially sharp. It all depends on user preference and the type of content we are watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution materials.

Samsung Q70D is the first model in the manufacturer's portfolio featuring a 120Hz panel. Consequently, its motion smoothing functions are more advanced than those in lower-tier models. Within the menu, we find three functions responsible for improving smoothness: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We will discuss the third one later. The first function is responsible for sharpness in motion, while the second adjusts the level of smoothing. The smoother in Samsung Q70D performs satisfactorily, and each setting brings noticeable changes. Therefore, those who dislike the characteristic juddering in films or are avid sports viewers will be able to achieve a personalised level of smoothing. In the picture, we present a setting with slight smoothing, without the soap opera effect.

The panel used in Samsung Q70D features a fairly good response time for this type of display. Of course, it won't be as sharp as a proverbial razor, but at this price, it is a recommendable choice for all kinds of sports.

The Panasonic Z85A features a 120 Hz panel, which will certainly please both gamers and sports fans. Admittedly, it is not 144 Hz like some gaming TVs, but in practice, the difference is really hard to notice. In games, the image is stable and clear, and during fast action, there is no sign of any blurring. The same applies to sports – a fast-running footballer or a dynamic car manoeuvre looks smooth and natural. The TV also has the “Intelligent Frame Creation” function, which is a motion smoother. There are two sliders here – one is for reducing blur, and the other is for motion smoothness. With these, you can adjust the image to your own preferences – whether it be more of a cinematic effect with gentle transitions between frames, or a maximally smooth image ideal for watching sports.

The tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the conducted tests, we did not find any negative effects related to this state of affairs. Moreover, and more importantly, Samsung Q70D supports all functions resulting from the aforementioned standard. This news will surely please all gamers, as it means that whether using a console or a PC, we can count on the highest possible comfort during gameplay. Given the typical absence of HDR Dolby Vision for this manufacturer, it is significant that the HGIG mode has been correctly implemented and there is no issue with setting the calibration checkerboard. We particularly note that Samsung, as the only manufacturer, allows gameplay with the smoothener turned on, without significant degradation. This means that titles running at 30 fps will be perceived like those with native 60 frames per second.

Samsung, as one of the first manufacturers, introduced the Game Bar to its televisions, which it has consistently refined since then. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

To summarise: Samsung Q70D performs excellently both with a console and a computer. All functions worked perfectly and there were no issues with them. The ability to enable the smoothener without a significant increase in input lag is a true game changer.

Panasonic is mainly associated with home cinema televisions, but the Z85A demonstrates that it can also step into the gaming world with a really strong impact. This hardware can easily be called a gaming beast – it has everything needed for comfortable gameplay.

Although there are 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 key features are supported: ALLM automatically switches the television to game mode, VRR ensures smooth images without stuttering or tearing, and with correctly 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 clear, circular menu. It may not look as impressive as the competition's, but it is intuitive and contains all the important settings we would like to have at hand during gameplay.

In summary – the Panasonic Z85A is equipment that truly surprises with its gaming capabilities. It is a television on which both console gamers and PC players will feel at home. It is smooth, dynamic, and simply good.

The latency results in Samsung Q70D are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which allow for a game running in 4K 120 Hz with HDR to have a mere 7 ms latency, which is virtually unnoticeable even in online games. It is worth adding that the lag with the smoothness enhancer switched on increases by about twice, which still means very comfortable gaming in this case.

Since the Panasonic Z85A has also been designed with gamers in mind, the input lag had to be refined here. And indeed – the results are truly excellent. At 120 Hz, the lag is only 5 ms, and at 60 Hz, it is 13 ms. These are values that will satisfy even the most demanding gamers, whether we are talking about fast-paced shooters or precise fighting games. The responses to our movements with the controller are practically instantaneous, and the gameplay is smooth and responsive. Importantly, the Dolby Vision mode also works flawlessly here. Just a few years ago, using Dolby Vision in games often resulted in high input lag, but in the Z85A, this problem has been effectively eliminated.

After connecting the television to the computer and wanting to use it as a monitor, we can expect a low input lag of 13 ms, which is practically unnoticeable along the mouse-screen-eye line. Thanks to the correct implementation of chroma 4:4:4, the readability of fonts is at a high level, so one can confidently connect the Samsung Q70D to the computer as a monitor and anticipate comfortable work with text.

The subpixel arrangement is BGR, which does not negatively impact the use of the television as a monitor. However, since operating systems are not adapted to such a subpixel format, this may cause slightly less clear outlines. Nevertheless, this is practically negligible and only a handful of people may notice it.

Using the Panasonic Z85A as a computer monitor performs really well. The text is readable and clear, making it easy to browse websites or work with documents. However, one must keep in mind certain limitations of the WOLED panel – the distinctive way it displays fonts may hinder more demanding users, especially those who spend long hours working with text. In terms of gaming on PC, the television performs just as well as with a console. Low input lag, a 120 Hz refresh rate, and proper implementation of G-Sync and FreeSync ensure a smooth and responsive image without annoying stutters or frame tearing.

Due to the VA panel, the performance of the Samsung Q70D in terms of viewing angles is its Achilles' heel. Even a slight shift from the axis results in a significant loss of contrast and a substantial degradation of colours.

The viewing angles on the Panasonic Z85A are really good – after all, it's OLED. Whether we're looking at the screen straight on or at a steep angle, the colours remain vibrant, and the contrast hardly loses quality. Of course, the Z85A is somewhat outperformed by televisions with MLA micro-lenses or Samsung's QD-OLED panels, which currently set the highest standard in this regard. However, the differences are subtle enough that most users won't notice them during everyday viewing.

The satin finish of the panel in the Q70D allows for quite good performance in a strongly sunlit room. It is worth noting that the reflections do not extend beyond their source, thus not spilling over onto the rest of the panel. We also commend the maximum brightness of the television in SDR materials, which is 450 nits, allowing for comfortable content consumption during the day.

The Panasonic Z85A leaves something to be desired during the day. The panel, despite being matte, moderately suppresses reflections, which can be noticeable in bright rooms. The reflections are not excessively visible, but there is one catch – they take on a bluish tint. In certain situations, especially in strong daylight, this can be slightly annoying and distract from the content on the screen. Additionally, the maximum brightness is just under 280 cd/m². That simply isn't enough to comfortably watch television in a brightly lit room. If we are planning a viewing in the middle of a sunny day, it will be necessary to cover the windows to ensure the image looks good.

The operation of the Samsung Q70D is powered by the proprietary Tizen system. It is quite a well-known software, as the manufacturer has been developing it in its televisions for a really long time. Its main advantage is smooth performance and the absence of significant stutters, which we can confirm through conducted tests. The greatest downside, however, is its closed nature. Although the app store is quite extensive, we are still at the mercy of the manufacturer. Therefore, we will not be able to install missing items, even from a pendrive. A perfect example of this is this year's discontinuation of support for the Tidal app. On the other hand, a benefit, especially for users of Apple equipment, is the implementation of AirPlay, which allows for easy mirroring of content from a device to the television. Fortunately, Samsung has also provided the option to connect a keyboard and mouse for much quicker navigation through the television's menu. It is worth mentioning that the manufacturer has luckily included a remote that connects via Bluetooth this year, which often did not occur in the past. The Tizen system has one more advantage. It integrates very well with external devices such as the NC+ decoder or soundbars. The connection process is very quick and does not require any special skills.

In summary: The Tizen system is very smoothly functioning software, which is certainly a strong advantage of the television. Although more advanced users may complain about the lack of at least KODI, the rest will be satisfied.

The operating system in the Panasonic Z85A is Amazon Fire TV, which is still a relatively new solution in the Polish market. Until now, we mainly associated it with portable smart devices, and now it is also making its way into televisions – similar to the flagship model Z95A.

On the plus side, it must be noted that the system operates smoothly and responsively. It is also quite intuitive, so navigation does not pose major problems. Unfortunately, when it comes to the availability of applications, it is somewhat lacking. In the Amazon store, we do find icons for popular services such as SkyShowtime, Rakuten, or Viaplay, but… they cannot be downloaded. This is a significant drawback for those who use these platforms daily. Additionally, some functions are poorly translated, which means in certain areas one has to guess what is meant. However, we believe that these are just growing pains, and over time they will be improved – both in terms of translations and application availability.

As for user functions, the situation is much better. The television supports recording to USB and the PiP (picture-in-picture) feature. There is also support for AirPlay, which will surely please users of Apple devices. We also have Bluetooth here, but unfortunately, we cannot connect headphones to it – it only works with keyboards and other control devices. Fortunately, it is possible to connect headphones or a home cinema system via cable, which resolves this issue.

In summary – the Panasonic Z85A offers a solid set of user functions that work well for everyday use. The Amazon Fire TV system is a step in the right direction, especially when compared to Panasonic's old system. However, at this moment, it is difficult to praise it unequivocally. There is potential, but the manufacturer still has a lot of work ahead to ensure everything functions as it should.

The built-in player Samsung Q70D is one of its major advantages. It handled almost all video and audio files prepared for the testing process excellently. The only exceptions in this regard are, of course, the Dolby Vision format (which is not surprising) and less popular codecs. Additionally, credit should be given for the support of Polish characters and the ability to change font colours. However, it performs worse with photo formats, as it only supports JPEG among the popular ones. There is definitely a lack of formats such as PNG or Apple's HEIC.

In terms of playback of files from USB, the Panasonic Z85A performs rather mediocrely. The built-in media player does handle most popular video formats, but it has one rather significant drawback – it does not support external subtitles. So, if we have older films on the drive or USB stick with separate subtitle files, we must reckon with the fact that the television simply will not display them. This is a considerable disadvantage, especially for those who use their own media libraries instead of streaming services. Of course, this problem can be circumvented by using an external media player (e.g. via a console or Smart TV box), but this is an additional step that could be avoided if the built-in application were better developed.

The built-in audio system Samsung Q70D, due to its slim design, is not among the most outstanding. The overall sound is fairly balanced, although we wouldn't advise increasing the volume above 2/4 of the scale. However, if we have a home cinema system, a number of codecs await us, notably featuring the most important ones, namely DTS-HD Master Audio and Dolby Atmos.

In terms of sound, the Panasonic Z85A is pleasantly surprising. The television delivers a pleasant and clear sound, and it can also generate a noticeable bass, which adds depth to both films and music. The surround effect is also quite well reproduced, making watching films or playing games more immersive. Unfortunately, there is one "but". The television does not support the DTS:X format, which is quite popular among more advanced home cinema systems. Therefore, if we plan to use this sound standard, it will be necessary to connect the audio equipment first to the amplifier or soundbar, and only then to the television.
