Compare: Samsung QLED Q70D / Q74D / Q77D vs Panasonic W70A

Samsung Q70D performed in the test exactly as it should for its price range – very competently. The strongest aspects of the television are certainly its performance when using a console and colour reproduction after the calibration process. The former will undoubtedly catch the attention of gamers with a range of conveniences that Samsung Q70D can offer, and there are quite a few, including that which is almost exclusive to the manufacturer's units – the ability to smooth out gameplay while still maintaining reasonable input lag, allowing 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 set correctly, is on par with games using Dolby Vision. We must also acknowledge the easy pairing of the television with the Canal+ decoder, which is not such an obvious advantage, but we know that many people experience issues with this. Staying on the topic of television, it must be noted that the Samsung Q70D offers very good brightness in SDR content for its price range, making daytime viewing more than comfortable. A downside for the tested television is the lack of Dolby Vision, which would have significantly enhanced performance at the maximum brightness of the Samsung Q70D. The device's construction flaws should not be overlooked, as they may (though not necessarily) lead to light bleed that can be noticed in dark situations during dimly lit scenes. What cannot be taken away from the Samsung Q70D is the fact that it features one of the better motion smoothers in its price bracket, which works excellently for sports events or fast-paced action scenes. The system responsible for the television's operation runs very smoothly, and the only thing we can criticise it for is the absence of the Tidal app. In summary, the Samsung Q70D represents a good continuation of the manufacturer's seventh series, which year after year is gaining – firstly, in quality, and secondly, in popularity.

The Panasonic W70A draws attention primarily because of its advanced Google TV operating system, which gives us access to a multitude of popular applications (YouTube, Netflix, Disney+, HBO Max, etc.). In terms of picture quality, the IPS panel offers wide viewing angles, so colours do not lose their intensity even when you watch a film from an angle. Gamers will also not be disappointed, as it features VRR and ALLM, along with low input lag (around 12 ms) – all of this translates to pleasant experiences during occasional gaming, despite the standard 60 Hz refresh rate.

However, it's worth noting that this is rather a basic model and has its limitations. The contrast and blacks are simply weak, which is a typical phenomenon for IPS panels, especially in dark rooms. A brightness level of around 270 cd/m² is also insufficient in heavily sunlit rooms, so the picture can seem washed out. Certain shortcomings in the software itself cannot be overlooked either. Google TV is a great foundation, but sometimes settings are scattered in surprising places, and the quality of translations leaves a lot to be desired.

It must be considered that the competition is offering more and more in a similar (or slightly higher) price range. Can the Panasonic W70A hold its own in such an environment? On one hand, it tempts with a rich app base and decent support for gamers, but on the other – the market is flooded with more polished TVs equipped with better specifications. However, if wide viewing angles and straightforward access to Google TV services are priorities, we can give it a chance. In other cases, it’s worth exploring among competitive models that often offer better blacks, higher brightness, and fewer annoying issues in the menu at a similar price.

Samsung Q70D and its related models, such as Q77D and Q74D, use a VA panel, which should inherently provide decent contrast. Typically, it is several times higher than that of IPS/ADS screens that do not come equipped with an advanced local dimming system. As you can see, contrast results are quite varied, which is caused by the unevenness of the panel. Therefore, we might sometimes get good contrast, and other times it can be significantly worsened, but generally, it remains fairly consistent, aside from light bleed. Let’s take a look at the film scenes we prepared from "Oblivion" and "Revenant." As we can see, in the first one, the lights are well separated, which is a positive phenomenon, as the visibility of details in bright areas in further tests should be equally good. What stands out the most here is the unusual oversharpening of the 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 unevenness of the backlighting of our piece. This was significant and strongly affected the perceived image. Nonetheless, the details in the film were well visible.

The Panasonic W70A is equipped with an IPS panel, which unfortunately is not the best choice if we care about deep blacks and high contrast. Additionally, the lack of local dimming means that instead of pitch-black areas on the screen, we see rather silvery and navy-blue patches. This was particularly noticeable in our tests on demanding screens with dark scenes. The contrast value, which hovers around 1000:1, is far from satisfactory – especially if we plan to watch movies in a darkened room. Scenes that should mesmerise with the depth of darkness instead look flat and lose their atmosphere.

The brightness that the Samsung Q70D can offer is at a rather average level, although it cannot be said that the HDR effect will not be noticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR content. As was the case in the paragraph about contrast and black levels, we can also observe here that the first scene, featuring a bright sunny sky and a darker foreground, has the lowest luminance of those measured. The result, which can be considered very good for this price range and display class, is that one. In a scene where we see a large light source filling a significant portion of the frame, the brightness of the TV is at its highest, reaching nearly 500 nits. However, it is worth noting the rather low coverage of the wide DCI-P3 colour gamut, which sometimes results in noticeable shortcomings in the colour reproduction. Additionally, users can enjoy rich colours and high precision in rendering shades, making movie screenings a unique experience. It is also worth mentioning that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

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.

The best factory mode in Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before the calibration process, it had several flaws that effectively hindered the presentation of the director's intentions. In both SDR and HDR material, the white balance was dominated by red and green colours. As a result, there was a characteristic yellow tint on the image, which caused whites to appear yellowed and skin tones to be noticeably too warm. The reduced gamma in standard colour palette materials caused a significant drop in contrast, which was already not the highest. This led to the highlighting of details in the blacks, but also to clipping in brighter scenes. In this case, the EOTF curve proved to be much better and only brightened those scenes with quite low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, a shot from the film "Billy Lynn" appeared unnaturally bright and lacking depth.

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.

Fortunately, Samsung provides a wide range of calibration tools in all its TVs, including 2- and 20-point grey scale adjustments and advanced CMS. As a result, we were able 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 delivers is definitely much closer to the reference. Higher deltaE errors in wide dynamic range content primarily result from the display's insufficient luminance.

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.

Considering how important lighting is in films and series, the overlapping structures and fluidity of tonal transitions constitute an extremely significant element in assessing image quality. The colour grading on the tested television is at quite a decent level. It cannot be said that it is outstanding, but it is not bad either. We assess it as acceptable. Brighter scenes perform best here, demonstrating the least amount of choppiness. In scenes recorded in darker settings, slight shortcomings in grading can already be noticeable, although it is not an issue that would cause discomfort while watching. This may be disturbed by the leaking backlight, which is clearly visible in the last image.

In terms of the smoothness of tonal transitions, the Panasonic W70A performs really well. The transitions between colours are smooth, without any noticeable and annoying "banding" or sudden jumps in hue. Even more demanding scenes, where subtle gradients dominate, look surprisingly good. Of course, a trained eye will notice some imperfections, especially in the brighter areas of the screen, where slight colour banding can be observed. However, this is not something that significantly affects the viewing experience and will be practically unnoticeable for most users.

Unfortunately, what detracts from the overall effect is the unevenness of the backlighting of the panel, which is quite noticeable and can distract from the quality of the tonal transitions themselves. This is particularly evident on uniform backgrounds, where the differences in brightness between various areas of the screen become more pronounced.

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

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

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.

Samsung Q70D is the first model in the manufacturer's portfolio with a 120Hz panel. As a result, its motion smoothing features are more advanced than those in lower-tier models. In the menu, we find three functions responsible for improving fluidity. They are "Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We'll discuss the third one later. The first function enhances sharpness in motion, while the second adjusts the level of smoothing. The smoothness enhancer in Samsung Q70D works satisfactorily, and each setting makes a noticeable difference. Therefore, those who dislike the characteristic stuttering of films or who passionately watch sports will be able to achieve their preferred level of smoothness. In the image, we present a setting with slight smoothing, without the soap opera effect.

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

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 tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the testing process, we did not observe any negative effects associated with this situation. More importantly, Samsung Q70D supports all features stemming from the aforementioned standard. This news will surely delight all gamers, as it means that whether using a console or a PC, we can expect the highest possible comfort during gameplay. Given the standard absence of Dolby Vision HDR for this manufacturer, it is significant that the HGIG mode has been implemented correctly and there are no issues with setting up the calibration chessboard. We particularly note that Samsung is the only manufacturer to allow gaming with the smoothness enhancer switched 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 has since been consistently refined. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

In summary: Samsung Q70D will perform excellently both with consoles and with computers. All functions worked brilliantly, and there were no issues with them. The ability to enable the smoothness enhancer without significant increases in input lag is a true gamechanger.

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.

Results of latency on the Samsung Q70D are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which allow a game running in 4K 120 Hz with HDR to have only 7 ms of latency, which is practically unnoticeable even in online gaming. It's worth adding that lag with the motion smoother turned on roughly doubles, which still means very comfortable gaming in this case.

In terms of signal delay, the Panasonic W70A performs really well. With a score of 12 ms, it's a value that is practically below the threshold where noticeable lag can be mentioned. Playing on this TV is responsive, and character movements or reactions in games are immediate. Interestingly, even in Dolby Vision mode, which often poses issues with input lag, the TV handled it very well. This is a pleasant surprise, as many manufacturers struggle with this, and HDR often increases the lag to a level that becomes noticeable during fast-paced games.

After connecting the television to the computer and wishing to use it as a monitor, we can expect a low input lag of 13 ms, which is practically unnoticeable on 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 you can confidently connect Samsung Q70D to your computer as a monitor and expect a comfortable experience with text.

The subpixel layout is BGR, which does not negatively affect the use of the television as a monitor. However, as operating systems are not adapted to this type of subpixel format, it may cause slightly less distinct contours. This is, however, something practically negligible, and only a handful of people may notice it.

The Panasonic W70A handles itself quite well as a work monitor. Thanks to its IPS panel and 4:4:4 chroma support, the text is clear, sharp, and readable. Even small fonts look good, without any blurring or jagged edges. For office work, web browsing, or document writing, this television is really suitable.

Gaming on PC is a bit of a different story. The 60 Hz panel means that more dynamic titles don’t look as smooth as they could on a higher refresh rate screen. The lack of G-Sync or FreeSync support doesn’t help either, so screen tearing may occur.

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

For a TV with an IPS panel, the viewing angles on the Panasonic W70A are really impressive. The image maintains decent quality even when viewed at a wider angle. Colours don't significantly lose saturation, and details remain well visible. Of course, everything comes at a cost. In this case, it's the weaker blacks, which become even more washed out when viewed at an angle. However, this is a standard compromise with IPS panels and is hard to consider surprising.

The satin finish of the panel in the Q70D allows for quite good performance in a well-lit room. It is worth noting that reflections do not spread beyond their source, and thus do not bleed onto the rest of the panel. We also commend the maximum brightness of the TV in SDR content, which is 450 nits, allowing for comfortable content consumption during the day.

The Panasonic W70A is fitted with a satin matrix that average manages to reduce reflections of light. Glare isn't overly bothersome, but in bright rooms, especially in direct sunlight, it can be noticeable. The main issue, however, is the brightness at a level of 270 cd/m². It's simply too little to comfortably watch television in full sun. The image becomes washed out, and darker scenes lose detail and depth.

The operation of Samsung Q70D is managed by the proprietary Tizen system. This is fairly well-known software, as the manufacturer has been developing it in their TVs for quite a long time. Its main advantage is smooth operation and a lack of significant stutters, which we can confirm through conducted tests. The biggest downside, however, is its closed nature. Although the app store is quite extensive, we are still dependent on the grace or displeasure of the manufacturer. Therefore, we will not be able to install missing items, even from a USB drive. A perfect example of this is this year's discontinuation of support for the Tidal app. On the other hand, a benefit, especially for Apple device users, is the implementation of AirPlay functionality, which allows for easy screen mirroring from a device to the TV. Fortunately, Samsung also provided the option to connect a keyboard and mouse for much quicker navigation through the TV menu. It’s worth mentioning that the manufacturer has thankfully included a remote that connects via Bluetooth this year, which often wasn't the case 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 special skills.

In summary: The Tizen system is very efficiently functioning software, which is certainly a strong advantage of the TV. While more advanced users may complain about the lack of something like KODI, the rest will be satisfied.

Panasonic W70A runs on the Google TV system and it's fair to say that this is one of its strong points. There are really a lot of applications – all the popular streaming services, YouTube, and even less known platforms. The system runs smoothly, and navigating through the menu is intuitive and hassle-free. The remote has a built-in microphone, so you can use voice search in Polish. This is a significant convenience, especially when you need to quickly find a movie or an application. Additionally, there's Bluetooth, which allows you to connect headphones or other wireless devices. However, there are some shortcomings. There's no AirPlay here, which could be a problem for users of Apple equipment. There's also a lack of USB recording options and picture-in-picture (PIP) functionality.

Panasonic W70A makes up for this with the functionality of Google TV and its straightforward operation. It has everything you need for using a Smart TV, but if someone is counting on more advanced options related to traditional television, they may feel slightly underwhelmed.

The built-in player Samsung Q70D is a significant advantage. It handled nearly all video and audio files prepared for the testing process exceptionally well. The only exceptions in this regard are of course the Dolby Vision format (which is not surprising) and less popular codecs. Additionally, it is worth noting the support for Polish characters and the ability to change font colours as a positive aspect. However, it struggles more with photo formats, as it only supports JPEG among the popular ones. There's definitely a lack of formats like PNG or Apple's HEIC here.

The built-in media player in the Panasonic W70A unfortunately has its limitations. Firstly, it doesn't support Polish subtitles, which can be a significant issue for many people. Additionally, there are difficulties with playing certain file formats, which sometimes results in an error message or a lack of sound.

Fortunately, thanks to the Google TV system, it's easy to install alternative media players that can handle these shortcomings. In the Google Play Store, we can find several reliable apps that support both Polish subtitles and less popular video formats.

The built-in audio system Samsung Q70D, due to its slim design, is not among the most outstanding. Overall, it's fairly balanced, although we wouldn't recommend cranking up the volume to levels higher than 2/4 of the scale. However, if we have a home theatre system, there is a range of codecs available, and we can enjoy the presence of the most important ones, namely DTS-HD Master Audio and Dolby Atmos.

The sound on the Panasonic W70A is surprisingly decent for a TV in this class. It's quite well balanced, and the low tones are subtly noticeable, which adds some depth when watching movies or listening to music. Dialogue is clear, and the overall sound quality is clean and pleasant. Of course, don't expect a cinematic experience or powerful bass – it’s still a standard audio system in a TV, and the physical limitations of its slim design take their toll.
