Our verdict

The Samsung Q70D delivers solid performance for its price range, with standout features that will appeal to a wide range of users. Its gaming capabilities, in particular, are impressive, offering features like smooth gameplay and low input lag that make 30 fps titles feel like they’re running at 60 fps. The well-executed HGIG mode, which performs similarly to Dolby Vision, is another highlight for gamers. Additionally, the Samsung Q70D pairs easily with Canal+ decoders, a feature many other TVs struggle with.

When it comes to daytime viewing, the Samsung Q70D shines with bright SDR content that makes it ideal for well-lit rooms. However, there are a couple of downsides. The lack of Dolby Vision is noticeable, as the TV’s brightness could have benefited from it, and light leakage can be seen in dark scenes with low brightness settings. While these issues are not dealbreakers, they are worth noting.

On the plus side, the Samsung Q70D has one of the best motion smoothers in its class, making it perfect for sports or fast-action content. The system runs smoothly and has all needed apps. Overall, the Samsung Q70D is a strong addition to the manufacturer's seventh series, with consistent improvements in quality and growing popularity.

At first glance, it's clear that the TCL A300 NXTVision wants to be more than just an ordinary television. It offers an image display mode that – unlike its competitors from Korea, Samsung The Frame – is completely free of charge. Additionally, like its rivals, freebies are included. In the package, in addition to the television, we find extra frames imitating light wood as well as a flat wall mount, allowing the television to truly resemble a gallery piece. In terms of everyday use, the Google TV system makes the biggest impression – it's extensive, fast, and offers access to a vast number of applications. And if we feel like stepping out of the digital museum and jumping straight into the gaming world, the A300 can surprise us. Two HDMI 2.1 ports, 144 Hz, VRR, ALLM, and very low input lag mean that even demanding gamers can feel at home here. Well... maybe except for those who are sensitive to ghosting – because that's still one of the model's major issues. There are also downsides. Although the picture mode is free – and that's worth appreciating – the quality of the available graphics clearly falls short of what Samsung offers in its paid ART Store. The images displayed resemble photos rather than realistic reproductions of artworks. Unfortunately, the A300 – like the competing Hisense S7NQ – performs poorly in this regard and additionally has some software issues. The brightness of the television itself also leaves much to be desired – it is the darkest television of the entire “frame trio,” which translates to average experiences during the day and limited HDR effects. Nevertheless, the TCL A300 NXTVision is a quite reasonable alternative to Samsung The Frame or S7NQ – especially if we are looking for a more affordable solution without additional fees for access to the "gallery" mode and with an operating system that doesn't limit us in terms of the number of applications. However, it should be noted that this is a proposition with a lot of compromises. If we want to save a bit and aren’t expecting top-end picture quality, then the A300 could be a picture-perfect choice. Otherwise, it’s worth looking at its competition.

Halo effect and black detail visibility:

The Samsung Q70D and its related models, like the Q77D and Q74D, feature a VA panel, which generally provides excellent contrast. Compared to IPS/ADS screens without advanced local dimming, the contrast on these models is several times better. However, the contrast results can vary significantly due to the non-uniformity of the panel. This means that sometimes the contrast is great, but at other times it can be noticeably worse, though it tends to remain fairly consistent overall, except for light bleeding.

To illustrate this, we look at two film scenes from "Oblivion" and "Revenant." In the first scene, the lights are well-separated, which is a positive as it suggests that detailed visibility in bright areas should be good in future tests. What stands out in this frame is the sharpness of the smoke under the light and the deep navy blacks in the background. In contrast, the second scene from "Revenant" reveals uneven backlighting, which is quite noticeable and impacts the overall image quality. Despite this, the details in the movie remained clearly visible.

TCL A300, also known as NXTVision, uses a VA panel, so right from the start, decent contrast could be expected. In our test patterns, the television did indeed show typical results for this type of panel – in the best case, the contrast reached about 5000:1, which is not a bad result for this segment.

However, it should be noted that the model is not equipped with any local dimming technology, which unfortunately shows in practice. Black, although at times quite deep, often shifts to blue or gray – especially in darker scenes. In short: for a television without local dimming, it's not bad, but there’s no point in comparing it to models that already have that feature on board.

TCL A300W NXTVision

Samsung QLED Q70D / Q74D / Q77D

The brightness of the Samsung Q70D is fairly average, yet it delivers a noticeable HDR effect. With brightness exceeding 400 nits, the distinction between SDR and HDR materials becomes evident. As observed in the discussion about contrast and black levels, the TV's performance varies across different scenes. In a scene featuring a bright sun against a darker foreground, the measured luminance is lower. However, in a scene with a large, bright light source dominating the frame, the TV achieves its peak brightness, reaching nearly 500 nits—a commendable result for its price range and display class.

Despite these strengths, the relatively low coverage of the wide DCI-P3 color gamut occasionally results in less vivid color reproduction. Even so, the TV offers rich colors and precise shade reproduction, enhancing the movie-watching experience. Furthermore, the Q70D excels in motion blur elimination during dynamic scenes, making it a solid choice for enjoying sports broadcasts and gaming.

When it comes to brightness, the TCL A300W is definitely the darkest TV among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, this is immediately noticeable. In our measurements, the peak luminance reached only about 400 nits, and on test film screens, this value dropped to 350 nits. This is definitely too little to feel the true "magic" of bright HDR effects. As a consolation – the TV is equipped with a PFS LED coating (which is something like QLED), which provides very good coverage of a wide color palette, both DCI-P3 and BT.2020. Additionally, there is full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the shortcomings in brightness and helps improve the overall perception of materials in this quality.

After calibration

The best factory mode on the Samsung Q70D is "Filmmaker," and it is the one we used when conducting various tests. Before the calibration process, it had several flaws that effectively prevented the conveyance of the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green colors. As a result, there was a characteristic yellow tint on the image, causing whites to appear yellowed and creating issues with skin tones, which were noticeably too warm. The reduced gamma in the standard color gamut materials caused a significant drop in the already low contrast. This resulted in an emphasis on details in the blacks but also in blown-out images in brighter scenes. The EOTF curve, in this case, turned out to be much better and only lightened those scenes with relatively low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, the frame from the movie "Billy Lynn" was unnaturally bright and lacking depth.

TCL A300 offers several picture modes, but without a doubt, the movie mode performs the best. Unfortunately, although it is the best choice among the available options, it is not free from errors. Both in HD and HDR content, the image has a noticeably too warm tint – leaning slightly towards pink, which is particularly noticeable in snowy scenes. Instead of pure white, we get a pinkish hue that spoils the natural perception of colors.

The brightness management doesn't perform well either. For older HD materials, the image often seems too dark – as confirmed by the inflated gamma value. Conversely, with HDR content, the effect is reversed – the image is overly brightened, which we observed in scenes from the movie Pan. This lack of consistency also affects color reproduction accuracy – a test with the ColorChecker showed that many samples deviate significantly from the reference values.

Fortunately, TCL allows manual adjustment of the settings, so we decided to check how the television would perform after our professional calibration. The effects of this correction are described below.

Color reproduction after calibration

8.1/10

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, where we can find 2-point and 20-point grayscale adjustments as well as advanced CMS. Thanks to this, we were able to significantly improve the quality of SDR and HDR materials. 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 the high dynamic range materials are primarily due to the display's insufficient luminance.

After our professional calibration, the TCL A300 literally got a new lease on life. The image is no longer too warm, and the colors finally look the way they should – which was confirmed by the ColorChecker test, where the color samples finally started hitting their marks, at least to some reasonable degree. It was also possible to partially correct the brightness management – the image is now more balanced and less "wobbly" between different types of content. Of course, certain limitations cannot be overcome – a slightly noticeable blooming effect still occurs, but that's a characteristic of the technology, not something that can be eliminated even after professional settings.

Generally: after calibration, the A300 looks significantly better and gains a completely new quality.

Smoothness of tonal transitions

6.9/10

8.6/10

Considering how important light play is in films and series, the overlapping structures and the fluidity of tonal transitions are an extremely significant element in assessing image quality. The color grading on the tested television is at quite a decent level. It cannot be said that it is outstanding, but it is also not bad. We rate it as acceptable. Brighter scenes perform the best here, showing the least amount of stuttering. In scenes recorded in darker settings, slight deficiencies in grading can already be noticed; however, this is not an issue that would cause discomfort while watching. This may be disrupted by the bleeding backlight, clearly visible in the last photo.

TCL A300 NXTVision is another frame-style television that really handles the smoothness of color transitions well. It's hard to find clear bands or sharp transitions between shades of the same color here – the overall look is natural and smooth.

However, it must be honestly admitted that among the three tested models (The Frame and S7NQ), TCL performs the weakest in this category. In darker and lighter scenes, delicate imperfections can be noticed. Nevertheless, looking at it as a whole, for a TV in this price range – it really presents itself solidly. It may not be the best among all, but it maintains a very good level.

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

Image scaling in Samsung Q70D should be rated as average. The manufacturer aims not to artificially sharpen the image but to leave it naturally softened.

TCL A300 handles tonal transitions in high-quality films very well, but the question arises – how does it perform with weaker materials? The television is equipped with a tonal transition smoothing feature, but its effectiveness can be described in one word: "random." In one scene it may work and improve the gradation, and when turned off… the effect remains the same. There is a lack of consistency and predictability.

Image scaling is also not one of the A300's strong suits. In the test pattern, the main character actually looked better than on the raw signal, but with thin lines – like fonts or background details – there was noticeable jaggedness and aliasing. On the plus side, the television does not cut off the image and has no issues with overscan, but the overall quality of scaling is rather average.

The Samsung Q70D is the first model in the manufacturer's range to feature a 120Hz panel, resulting in more advanced motion smoothing capabilities compared to lower-category models. Within the menu, three functions are dedicated to improving motion fluidity: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." The third option will be discussed separately. The first function enhances sharpness during motion, while the second adjusts the degree of smoothing. The smoothness feature on the Samsung Q70D performs well, with each setting delivering a noticeable effect. This allows viewers to customise the level of fluidity, making it suitable for those who dislike the typical stuttering of films or enjoy watching sports. The accompanying picture illustrates a configuration with mild smoothing, avoiding the soap opera effect.

The panel employed in the Samsung Q70D offers a commendable response time for its class. While it won't deliver razor-sharp motion clarity, it is a strong choice for sports enthusiasts at this price point.

The TCL A300 is equipped with a 144 Hz panel, which should immediately satisfy practically everyone – both gamers and sports fans. The motion is smooth, and the picture is clear even in fast scenes. Additionally, the television offers a motion enhancement feature called "Motion," where we can find two sliders on a 10-point scale. These allow for adjusting the effect to personal preferences – from a classic, cinematic look with visible frames to a very smooth (though already unnatural) image reminiscent of a soap opera effect. Thanks to this, everyone can find a setting that suits them.

The tested television, Samsung Q70D, has four HDMI 2.1 ports, all offering a bandwidth of 40 Gbps. Despite this, no negative effects were noticed during testing. More importantly, the TV supports all features associated with the HDMI 2.1 standard. This will certainly please gamers, as it ensures optimal gaming performance using a console or a PC. While HDR Dolby Vision is absent, the correct implementation of HGIG mode and the absence of any calibration checkerboard issues are noteworthy. Additionally, Samsung stands out by allowing gaming with the smoothness enhancer activated without significant performance degradation. This means that 30 fps titles are perceived similarly to those running at a native 60 frames per second.

Samsung was one of the first manufacturers to introduce the Game Bar, which has been consistently improved. It provides all necessary gameplay information and allows users to adjust "on the fly."

In summary, the Samsung Q70D performs excellently with both consoles and computers. All functions worked seamlessly, and there were no issues. The ability to activate the smoothness enhancer without a noticeable increase in input lag is a game-changing feature.

TCL A300 is a television designed not only to transport us to a digital art museum but also to a full-fledged gaming world. It offers practically everything you would expect from gear for gamers: two HDMI 2.1 ports with full bandwidth, 144 Hz refresh rate, VRR support, and ALLM.

The correct implementation of the HGIG mode is also a plus – something that competing Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which will be appreciated by owners of older consoles or PCs.

In addition, there’s an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is truly well-prepared for gaming at the highest level – it's just a shame that issues with motion blur slightly tarnish its overall image as a gaming device.

The delay performance of the Samsung Q70D is excellent, regardless of the signal or resolution. Gamers will certainly appreciate the manufacturer's efforts, as a game running in 4K at 120 Hz with HDR experiences only 7 ms of delay, which is practically imperceptible even in online games. It is also worth noting that enabling the motion smoother doubles the lag, but it still provides a very comfortable gaming experience.

In terms of input lag, the TCL A300 performs really well. Values below 10 ms at a 120 Hz refresh rate are something many gamers dream of – such low lag is practically imperceptible, both during everyday gaming and in more demanding esports titles. One could indeed point out the result of 23 ms in Dolby Vision mode at 60 frames, but it is still a low enough value that it's hard to have serious objections. In this category, the A300 truly excels.

After connecting the Samsung Q70D to the computer and using it as a monitor, input lag is impressively low at just 13 ms, making it virtually imperceptible in the mouse-to-screen experience. Thanks to the proper implementation of chroma 4:4:4, font readability is excellent, meaning the TV can confidently serve as a monitor for text-based work.

The subpixel arrangement is BGR, which doesn’t negatively affect using the TV as a monitor. However, since most operating systems are not designed for this subpixel format, it may result in slightly less sharp contours. This is a minor issue, barely noticeable to most users.

If we plan to use the TCL A300 as a monitor for a computer, we may be pleasantly surprised. The television performs really well in this role. It is equipped with a 144 Hz panel, supports G-Sync, and, as we mentioned, offers very low input lag, so gaming on it with a connected PC is pure pleasure.

Working with text is also possible, although with some limitations. The TCL A300 has slight issues displaying dark fonts and thin lines – this stems from the structure of the subpixels, which can be somewhat bothersome in everyday use, even though it looks better in pictures than in reality.

The television supports chroma 4:4:4, but only up to 120 Hz. That's why we noted that this feature is available, but with a limitation – if we care about perfectly legible fonts, it's worth sticking to a refresh rate of 120 Hz. At 144 Hz, the sharpness of the text may suffer slightly.

Due to the VA panel, the Samsung Q70D struggles with off-angle viewing. Even a slight shift in position leads to a noticeable drop in contrast and a significant loss of colour accuracy.

The viewing angles on the TCL A300 NXTVision are – let's be honest – average. The television is equipped with a VA panel, which inherently has quite limited angles, and unfortunately, you can clearly see that here. The film below speaks for itself – even a slight deviation from the axis results in a noticeable drop in contrast and color saturation. It’s a pity that this is another frame-style television that hasn’t done anything about it. After all, we don’t always have the option to sit perfectly straight in front – especially if the device is also meant to serve a decorative function in the living room.

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

The TCL A300 NXTVision is equipped with a matte panel very similar to the one found in one of its Chinese competitors – the Hisense S7NQ model. Such a surface does quite well in suppressing reflections, although it must be admitted that it performs worse than Samsung's The Frame, which offers a definitely higher level in this respect. As is often the case with matte displays, blacks during the day lose depth and appear more gray than black – and this is no different here. Unfortunately, the fact that the A300 is the darkest television among the tested trio does not help either. As a result, it has a real problem standing out in heavily sunlit rooms.

The Tizen system powers the operation of the Samsung Q70D. It is a well-known software, as the manufacturer has been developing it for its televisions for a long time. Its main advantage is smooth operation and the absence of significant stuttering, which is confirmed by our tests. However, its biggest downside is its closed nature. Although the app store is quite extensive, users are still at the mercy of the manufacturer. As a result, we cannot install missing apps, even from a pendrive. On the other hand, an advantage—especially for Apple device users—is the implementation of AirPlay functionality, which allows easy screen mirroring from the device to the television. Thankfully, Samsung has also included the option to connect a keyboard and mouse for much faster navigation through the television menu. It’s worth noting that this year, the manufacturer has included a Bluetooth remote, which often wasn’t the case.

The Tizen system has another advantage: it integrates very well with external devices, such as the NC+ decoder or soundbars. The connection process is quick and doesn't require special skills. One of the standout features of the Samsung Q70D in our tests is the speed of application operation, with apps loading almost instantly and eliminating annoying delays. Additionally, users can utilize the built-in voice assistant, simplifying navigation and content searching.

In summary, the Tizen system is very efficient software and certainly a strong advantage of the television. While more advanced users may complain about the lack of apps like KODI, the majority will be satisfied.

TCL A300 is a television styled like a painting, which in everyday use can successfully imitate a work of art hanging on the wall. It is equipped with a special image display mode, additional frames in a light wood tone, and a flat wall mount that allows the TV to be hung like a real painting – flush against the wall.

A significant advantage of the picture mode is that it is completely free. We have access to dozens of artworks from which we can choose what should be displayed in standby mode – instead of a black screen, the image selected by us stays on the wall. The quality of the graphic reproduction is decent, but it must be admitted that it clearly falls short compared to that of Samsung's ART Store. Although access to the images there is paid, the quality of the scans is significantly better – you can see the texture of the paint, canvas, and details. In the TCL A300, it resembles high-quality photos more than realistic reproductions of artworks. Additionally, the implementation of the picture mode in the system leaves much to be desired. For example – if we set the brightness in picture mode to 10%, this same value automatically transfers to the regular viewing mode, where we could easily set the brightness to 50% or even 100%. It also works the other way around – when we set the brightness to 100% in regular mode, after switching to gallery mode, the images are displayed with that same maximum brightness, shining too intensely and losing the entire effect of "a picture on the wall." These are minor but annoying errors that can ruin the impression of what was supposed to be visually subtle and elegant.

Moving on to more classic features – the A300 runs on the Google TV system, which currently offers by far the largest selection of applications (full list available below). The well-functioning voice assistant with support for the Polish language is also a significant plus. As is standard – as in most TCL televisions – there is a lack of USB recording functionality or picture-in-picture (PiP) mode.

The built-in player of the Samsung Q70D is a major advantage. It handled almost all video and audio files prepared for testing excellently. The only exceptions were the Dolby Vision format (which is not surprising) and some less popular codecs. On the positive side, the player supports Polish characters and allows users to change font colours. However, its performance with photo formats is lacking, as it only supports the popular JPEG format. Other formats, such as PNG or Apple's HEIC, are notably absent.

The built-in player in the TCL A300 works as it should – most popular video and photo files play without any issues. Although it lacks support for the HEIC format from Apple (which is quite common in many TVs), most users still rely on the AirPlay feature, so it shouldn't pose a major problem. If someone is not satisfied with the default player, the Google TV system offers considerable options – it's easy to install an alternative app that better matches our preferences. Nonetheless, it must be admitted that the factory solution is completely sufficient for everyday use.

Constrained by its slim design, the built-in audio system of the Samsung Q70D is not particularly remarkable. The sound is relatively balanced overall, but increasing the volume beyond 2/4 of the scale is not advisable. On the other hand, for those with a home theatre system, the TV supports a range of audio codecs, including the most essential ones: DTS-HD Master Audio and Dolby Atmos.

When it comes to sound, the TCL A300W – like its competitors – sounds quite... flat, after all, we are talking about a super slim TV. For everyday watching of news or series, this level is completely sufficient, but during movie screenings, it may clearly lack depth and space. On the plus side, it’s worth noting that the TV supports both Dolby Atmos and the increasingly rare DTS:X – which provides more options when connecting an external audio system. It’s also worth mentioning that the A300 PRO model is equipped with a dedicated, flat soundbar. And it's no ordinary one – it sounds better than most of the TVs we tested.
