Sony X75WL vs TCL A300W NXTVision

The luminance chart for the Sony X75WL revealed a peak brightness of just 350 nits, which is underwhelming for an HDR-capable display. This limited brightness means that HDR scenes lack the depth and impactful highlights expected for immersive viewing. Additionally, the subpar coverage of the DCI-P3 colour gamut results in a less vibrant colour representation, negatively impacting the overall quality of HDR content. The combination of insufficient brightness and poor colour gamut coverage significantly diminishes the intended HDR effect, making this model a less compelling choice for those prioritising HDR performance.

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.

Colour reproduction tests on the X75WL model, conducted in movie mode, reveal strengths and weaknesses. While movie mode offers some of the best image settings, it is not flawless. One of the most significant issues with the X75WL is the white balance, particularly for HD and 4K HDR content, where a blue hue dominates the image. This results in a noticeably cold tone throughout. The colour checker confirms these discrepancies, showing a clear shift towards cooler shades.

Regarding brightness, the contrast gamma level is generally acceptable, but the EOTF curve presents more challenges. There are noticeable problems with maintaining consistent brightness, with the image sometimes appearing too washed out or too dim. These issues affect the overall visual experience and hinder the accurate perception of content.

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.

The X75WL is one of those cases where image calibration may not lead to a dramatic transformation, but it does offer a notable improvement in colour perception. The white balance for HD and 4K content, has been significantly enhanced, eliminating the strong dominance of cooler tones. The gamma chart also appears more stable, resulting in better image quality overall. However, the main issue remains the EOTF curve, which controls brightness in 4K content. Due to the technological limitations of the television (such as the IPS panel and the absence of local dimming), a significant improvement is difficult to achieve, as the model’s capabilities are constrained. Despite these limitations, the tonality of the image has been substantially improved.

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.

The X75WL struggles with low-quality tonal transitions. The lack of any function to improve tonal gradation results in noticeable imperfections in colour transitions, which detracts from the overall image quality. However, the digital processing is commendable, with the image displayed without overscan, and relatively sharp presentation. This added sharpness may appeal to some users, though it does not compensate for the tonal transition issues.

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 X75WL features a 60 Hz panel, making it more suited for movie-watching than high-speed gaming. It is equipped with a motion smoother function called Motionflow, which allows users to adjust picture fluidity on a 10-point scale. This function adds intermediate frames, improving motion smoothness and creating a more cinematic effect by reducing choppiness. Additionally, the clarity adjustment helps reduce motion blur, making it particularly beneficial for fast-paced scenes like sports or dynamic action sequences in films. With these settings, users can fine-tune the fluidity and sharpness of motion to their preferences.

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 X75WL is not the best television for gamers, as it lacks some key features that more demanding users expect. While it includes the Auto Low Latency Mode (ALLM) and a basic Game Bar, these are not sufficient for a truly immersive gaming experience. In this price range, features like VRR (Variable Refresh Rate) and a 120 Hz refresh rate—at least in Full HD—have become standard, but unfortunately, these are missing in the X75WL. This is a significant drawback for Sony, as the competition offers more advanced gaming features at a similar price.

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.
