Compare TCL C855 vs TCL A300W NXTVision

The TCL C855 is a standout television in the TV market, showcasing a versatile performance across various applications and excelling in its price range. With Mini LED backlighting, the TV achieves impressive contrast and black levels, resulting in deep, vivid images. Its algorithm effectively maintains black uniformity, minimizing blooming effects, a significant advantage for viewing HDR content.

While the TCL C855 can reach brightness levels of up to 1800 nits, which is commendable, it is worth noting that brightness can significantly drop to around 200 nits when bright but small elements appear on-screen. Additionally, the mid-tone boost can compromise contrast and reduce fidelity to the director's original vision.

For gamers, the TCL C855 shines brightly, offering extremely low latency and high-quality performance thanks to its full implementation of HDMI 2.1 features. The inclusion of the Google TV operating system adds to its appeal, providing nearly limitless options for application installation, including support for APK files from outside the official store.

The TCL C855 is an excellent choice for those seeking a reliable and versatile television. While it may have some drawbacks, its overall image quality, gaming performance, and advanced operating system make it a strong contender in the market.

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.

The TCL C855 features a high-contrast VA matrix, achieving an impressive ANSI contrast ratio of 5238:1 without dimming. This level allows for very good black levels. Furthermore, the panel incorporates multi-zone Mini LED backlighting, divided into 1344 independent dimming zones for the 65-inch model. Such a configuration yields excellent results in our tests. Notably, TCL is among the few manufacturers offering such advanced panel specifications at a reasonable price, unlike the traditional big four brands. In the majority of scenes we evaluated, the performance was impressive, particularly in the first three tests; even in the third, with a ratio of 54,000:1, the black level and contrast were far from weak, demonstrating satisfactory results. However, performance does dip in two specific scenarios: scenes with movie strips and when the screen contains many elements surrounded by black. While the last test scene maintained excellent contrast, the final scenario revealed some blooming in the blacks. A frame from the movie "Oblivion" showcased the TCL C855's capabilities, with black levels that can rival those of OLED screens—a notable achievement. The television also demonstrates commendable light separation, which is no small feat. In our flagship scene from "Sicario 2" the contrast was equally impressive, although some loss of detail in the blacks across the first, second, and third planes was evident. The backlight control algorithm effectively minimizes halo and blooming effects, which is praiseworthy. However, it's important to note that very small elements, like stars, can occasionally be completely dimmed by the TCL C855.

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.

The TCL C855 delivers a highly varied HDR effect. At times, the television truly excels, while at other moments, it appears reminiscent of a low-end model equipped with FALD backlighting. Inconsistency is frequently found with this brand, so it didn’t come as a surprise. The first and last scenes, which feature large light elements, are nothing short of spectacular, boasting brightness levels of 1470 and 1820 nits, respectively. Such brightness can make viewers squint their eyes, allowing them to feel the extraordinary dynamism of the scene. It genuinely immerses the audience, creating a sensation of being inside the movie itself. However, the situation shifts dramatically when small or subtle elements with high luminance appear against a dark background. In these instances, the TCL C855 significantly reduces brightness to levels as low as 240 nits to mitigate halo effects. This reduction is disappointing, as it can make the movie appear as if it was not filmed in HDR. Despite these shortcomings, the HDR effect on the TCL C855 enhances the viewing experience during dynamic scenes, making it feel more engaging and allowing the viewer to feel part of the action. Even with smaller high-luminance elements, the television retains details without excessive dimming. Additionally, the TCL C855 adjusts image brightness according to scenes with rich detail, further enhancing viewing comfort.

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.

The best factory mode for the TCL C855 is the "Film" setting, and all our tests were conducted using this mode. However, like many predefined modes, it has flaws that should be addressed to achieve an image closer to the producer's original vision. In our examination of the colour characteristics for both SDR and HDR materials, issues were found.

Focusing first on SDR content, there is a noticeable dominance of green in the white balance, which leads to an unpleasant greenish tint across the entire image. The gamma chart, crucial for image contrast, shows a significant deviation from the reference line marked at 2.4. Initially, there is a pronounced spike in the measured value, resulting in an over-contrasted image where details can merge into a dark blob. This condition persists for nearly 20% of the chart before it dips below the reference line, causing the image to brighten and resulting in a substantial drop in contrast.

In HDR materials, the factory mode performs somewhat better; the white balance appears more balanced overall, although the green tint resurfaces in the latter half of the spectrum. When we look at the Electro-Optical Transfer Function (EOTF) curve—unlike gamma, which reflects contrast—we identify two main errors: the darkest scenes are too dark, while the brightest ones become overexposed. This discrepancy was evident in our review of the scene from the movie "Pan," further illustrating the TCL C855's HDR performance issues.

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.

TCL, like most manufacturers, offers advanced calibration tools within its televisions. These include both 2-point and 20-point adjustments for grayscale, as well as a comprehensive colour management system. As a result, we achieved impressive results in SDR materials, bringing the image significantly closer to the reference standard. We successfully eliminated both the green tint and the gamma issue, although a slight "kink" at the very beginning of the gamma curve still persists.

In contrast, the situation with HDR materials was less favourable, as the TCL C855 did not allow for precise modelling. We were only able to make minor adjustments to the EOTF curve while significantly enhancing the overall colour accuracy. This limitation suggests that while calibration tools are effective, they may require further refinement for optimal HDR performance.

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.

Another important aspect of assessing image quality is tonal transitions. To achieve a clean image free from posterisation effects, a television must employ highly effective algorithms for smoothing colour gradations. We must acknowledge that the algorithm used in the TCL C855, known as "Gradual Smoothing," ranks among the best we've had the opportunity to test. In nearly every scene, the performance is impressive, leaving little room for criticism. A prime example of this capability is the scene from "The Green Knight," which poses a challenge due to the multitude of fine and subtle transitions in the fog. The C855 successfully smooths out the details within this scene, allowing the viewer to fully appreciate its suspenseful atmosphere. The only instance where slight posterization is noticeable occurs in a frame from "The Green Knight," where the reds in the upper left part of the screen create a contrasting effect.

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.

Once again, we will take a look at the function of smoothing tonal transitions, but this time also image scaling. The latter is particularly important when watching materials of lower quality, such as some television programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes from the previous test where it performed excellently and smoothed out practically all the inconsistencies, here it had issues. Using the menu responsible for the operation of this function, we found that no setting—even the strongest—was helpful.

Image scaling in TCL C855 is defined as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural to our eye. Even small, fine branches do not have jagged edges, and there is no white halo around figures, a characteristic of weaker scaling systems.

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 maximum refresh rate you can set on the TCL C855 is 144 Hz. Naturally, this is only possible after connecting the TCL C855 TV to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we want to watch primarily sports or materials with a lot of motion dynamics. For those who require high image fluidity, the manufacturer has implemented a multi-stage motion smoother. It is divided into two separate sliders which control the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be adjusted from 0 to 10, with each level affecting the degree of fluidity, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect. The matrix of the TCL C855 features a very good response time. This is particularly important since VA panels often struggle with the so-called ghosting effect, where a black halo can be observed behind a fast-moving object. where a black halo can be observed behind a fast-moving object.

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 TCL C855 TV has fully-featured HDMI 2.1 ports, boasting a full bandwidth of 48 Gb/s. During our testing, we confirmed the seamless operation of all functions included in this connection standard. As highlighted, all checkboxes are illuminated in green, a feature that will undoubtedly be appreciated by gamers, whether on consoles or those using the TV as a computer monitor. Additionally, the TCL C855 supports both AMD FreeSync and NVIDIA's G-Sync, which can be easily activated in the graphics card settings. Those with powerful configurations can feed a 144 Hz signal to the C855, which handles this effortlessly. It is also worth noting the implementation of the HGIG mode, which can be excessively bright due to the shortcomings of the "Game" mode, making proper configuration on the screen challenging. Fortunately, the TV excels with the Dolby Vision format.

TCL, as one of the pioneering manufacturers, has equipped its televisions with a special GameBar, allowing for extensive adjustment of settings "on the fly" without the need to exit the game. This feature includes options like an additional crosshair grid, black level correction, and settings designed for individuals with disabilities. The image showcases the next generation of this solution.

In summary, the TCL C855 TV is an ideal choice for those seeking a screen for all forms of electronic gaming. With comprehensive features supporting such entertainment, it provides an extremely engaging experience. It is also important to emphasise that it maintains very low input lag, regardless of the selected settings, including when using the Dolby Vision HDR format.

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 input lag of the TCL C855 is impressively low across all scenarios. Even the most dedicated gamers will appreciate the minimal input lag of just 7 ms at demanding 4K 120 Hz settings with HDR. Furthermore, this lag remains consistent when enabling Dolby Vision HDR, which is not always the case with competing models. As such, the TCL C855 merits the highest rating and recommendation.

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.

When connected to a computer as a monitor, the TCL C855 performs exceptionally well. This is largely due to its very low latency time along the mouse-eye-screen line and excellent font readability, achieved through a chroma 4:4:4 at all resolutions, including 4K@144Hz.

The subpixel layout is BGR, which does not negatively affect usage in the Windows environment. However, this situation may change when using macOS or other software that cannot adjust fonts to accommodate this subpixel layout.

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.

A well-known drawback of VA panels without an angle coating is their poor performance regarding viewing angles. This holds true for the TCL C855, where even a slight deviation from the central axis results in noticeable image fading and colour degradation.

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 glossy finish of the TCL C855 panel prevents it from achieving the highest rating for daytime viewing performance. However, this finish contributes to impressive black levels during the day. The high brightness in SDR material makes the actress's face stand out prominently against reflections. A downside of this panel is that light falling directly on the screen tends to "spill" rather than being contained in one area. Generally speaking, if sunlight does not directly hit the panel, the TCL C855 remains a solid choice for well-lit rooms.

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 TCL C855 operates on the Google TV platform, which offers a significant advantage over TVs with proprietary systems from other manufacturers, where installing applications from a USB drive can often be challenging or impossible. With Google TV, users can install virtually any application, whether from the official store or directly from online repositories via APK files.

This system also provides various conveniences in terms of control. Users can connect a keyboard with a touchpad, making it easier to enter queries. Additionally, thanks to integration with Google, voice control features via the remote work very well, although minor issues may occasionally arise with function translations. It's worth noting that Google TV regularly receives updates that enhance functionality and introduce new options. However, according to reports from users of older models, the software can sometimes have its off days, leading to occasional performance hiccups.

In summary, Google TV is currently one of the most popular systems on the market. Thanks to its efficient CPU, it runs very smoothly, avoiding freezing and stuttering for the majority of usage. This makes it an excellent choice for those looking to fully utilise the capabilities of the TCL C855 and who appreciate the openness of the system.

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 default file player on the TCL C855 performs admirably with nearly all the media formats tested. Most video formats are supported, providing a versatile viewing experience. However, a notable drawback is the lack of functionality to change font colours. When it comes to photo playback, the TV handles high-resolution images well, but it is worth mentioning that it does not support Apple's HEIC or SVG file formats.

On the audio front, the TCL C855 manages to play various audio files without any issues, although it's unlikely that many users are reliant on formats like AIFF or DSD64. A significant advantage of the C855, alongside its operating system, is the ability to download alternative media players from the app store, ensuring compatibility with a wider range of file types.

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.

When evaluating the sound quality of the TCL C855, several key aspects come into play, such as clarity, balance, and the absence of dominant frequencies. In this case, the sound performance is commendable; it is well-balanced and does not evoke any negative sensations, providing an overall good audio experience.

For those who utilise a home theatre system, the TCL C855 supports a wide range of audio codecs, including the two most significant ones: DTS-HD Master Audio and Dolby Atmos. This support ensures high sound quality, making it a suitable choice for users seeking an enhanced audio experience.

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.
