Samsung QD-OLED S90D / S94D vs TCL A300W NXTVision

In the HDR effect category, the Samsung S90D delivers remarkable performance. On the luminance graph for up to 10% of the window, the television surpasses the 1000 nits mark, which is a notable achievement. However, in the film scenes we tested, these values were slightly lower. In scenes with fullscreen sun glare the brightness drops to about 500 nits, but this is still considered a very good result. It is also worth noting that this model stands out due to its very high colour gamut coverage, thanks to the QD-OLED panel, giving it an edge over televisions with WOLED panels, which cannot achieve such a wide spectrum of colours.

When it comes to brightness, the TCL A300W is definitely the darkest television 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 a mere 400 nits, and on test film patterns, this value dropped to 350 nits. This is definitely too little to experience the true “magic” of bright HDR effects. As a consolation – the television is equipped with a PFS LED coating (which is something like QLED), providing very good coverage of a wide colour gamut, both DCI-P3 and BT.2020. In addition, it has full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the lack of brightness and helps improve the overall perception of content in this quality.

The Samsung 65" S90D with a QD-OLED panel has been tested in Filmmaker Mode, which the manufacturer has used for years to deliver optimal picture settings. In this mode, the TV offers a very good image, but there are some shortcomings worth noting.

In terms of white balance, viewers may notice a red dominance in HD content, which can make skin tones appear unnatural and create a warm overall scene, potentially affecting immersion. This issue becomes more apparent in scenes where subtle colour differences are important. The same effect can be observed in 4K HDR content, though the red shift is less pronounced. This shift can prevent certain details and colours from being fully realised, diminishing the naturalness of the image.

As for contrast, the gamma performance is decent but still has some issues. The gamma values fall short of the reference level of 2.4, resulting in bright areas of the image appearing washed out and dark areas lacking detail. This limitation can make certain scenes feel less dynamic and impact the depth and richness of the picture. However, the EOTF curve for contrast in 4K HDR content performs well, showing the TV's ability to handle differences in brightness. That said, these values still fall slightly below the ideal range, indicating room for further optimisation.

Overall, the Samsung S90D in Filmmaker Mode offers solid colour reproduction, but some adjustments are needed to fully unlock its potential, particularly with different types of content.

TCL A300 offers several picture modes, but without a doubt, the best is the movie mode. Unfortunately, although it is the best option available, it is not free from errors. In both HD and HDR content, the image has a noticeably too warm hue - it leans slightly towards pink, which is particularly noticeable in scenes with snow. Instead of pure white, we get a pinkish tint that spoils the natural perception of colours.

The management of brightness is also not very good. In the case of older HD material, the image often seems too dark - which is confirmed by the inflated gamma value. Conversely, with HDR content, the effect is the opposite - the image is overly bright, which we observed in scenes from the film Pan. Such a lack of consistency also affects the accuracy of colour reproduction - a test with the ColorChecker showed that many samples clearly deviate from the reference values.

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

The quality improves more than anticipated after calibrating the S90D television in movie mode. The white balance for HD and 4K HDR content has been fine-tuned to near perfection. While minor imperfections are still noticeable, they are subtle enough not to significantly impact the overall picture quality. Colours have become more cohesive, promoting a natural reproduction of details, particularly in scenes where precise colour representation is essential. It’s important to note that this particular model, in this size, uses a QD-OLED panel, which offers a broader colour gamut compared to other versions of this model equipped with a WOLED panel.

The contrast has also seen a marked improvement. After calibration, the gamma chart is much closer to the expected curve, resulting in a better balance between the bright and dark areas of the image. The EOTF curve, which previously indicated issues with overexposed scenes, now shows significantly better results. This improvement allows for greater preservation of details in the brighter parts of the image, particularly in HDR content.

After our professional calibration, the TCL A300 has literally received a new lease of life. The image has stopped being too warm, and the colours finally look as they should – which was confirmed by the ColorChecker test, where the colour samples finally started to hit their marks, at least to some reasonable extent. 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 is still present, but that is a characteristic of the technology and not something that can be eliminated even after professional settings.

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

The television excels at smoothing tonal transitions, allowing colours to blend seamlessly, resulting in a natural and fluid image. The built-in noise reduction feature can further enhance these transitions, useful in certain situations. However, it is important to note that activating this option may overly smooth out the desired film grain structure, potentially compromising the authenticity and atmosphere of the image. Therefore, caution is advised when using this feature, to maintain the character and depth of the content.

The S90D model handles lower-resolution materials effectively, as demonstrated in the displayed image. The model's silhouette remains sharp and naturally reproduced, with fine details preserved. Additionally, the branches of the trees are well-defined, free from any visible jagged edges that might otherwise degrade the image quality. Thanks to efficient scaling, even lower-resolution content appears attractive on the screen, which is sure to please users who rely on a variety of content sources, such as standard cable or antenna television.

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

Image scaling is also not one of A300's strong points. On the test chart, the main character actually looked better than on the raw signal, but with thin lines – such as fonts or background details – there was noticeable jaggedness and aliasing. On the positive side, the television does not crop the image and has no problems with overscan, but the overall quality of scaling is rather average.

The S90D TV, featuring a 120 Hz refresh rate matrix and up to 144 Hz in the appropriate PC configuration, delivers excellent motion fluidity. Samsung highlights a range of sharpness settings on a ten-point scale, allowing users to fine-tune the display to their preferences. In UFO tests, the OLED matrix showcases its strengths by eliminating any blurring. The ultra-fast pixel response ensures dynamic movements are faithfully reproduced.

Similar results can be seen in other sizes of this model with a WOLED matrix, which also offer outstanding image fluidity. Organic technology, in this case, is considered among the best on the market. The S90D image, regardless of the matrix type, is exceptionally sharp and detailed, making this television perfect for dynamic scenes, whether for gaming or sports broadcasts. Additionally, its refresh rate and sharpness capabilities guarantee that every movement is smooth and natural, satisfying even the most discerning users.

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 image is clear even during fast-paced scenes. Additionally, the television offers motion enhancement functionality called "Motion," where we find two sliders on a 10-point scale. These allow you to adjust the effect to your own preferences – from a classic, cinematic look with visible frames to a very smooth (though somewhat unnatural) image reminiscent of soap opera effects. This way, everyone can find a setting that suits them.

The S90D television is an excellent solution for gamers, offering a range of advanced features that elevate gaming quality to a new level. Equipped with HDMI 2.1 standard, the model supports modern technologies such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Thanks to these solutions, the image is incredibly smooth, and the response to commands is instantaneous, which is crucial in dynamic titles. Additionally, the S90D supports HLG (Hybrid Log-Gamma) as well as G-Sync and FreeSync image synchronisation. This enables a perfect connection with Xbox, PlayStation, or PC, eliminating issues with tearing and stuttering. The built-in operating system offers the Xbox Game Pass app, providing access to a vast library of games directly from the television. This solution makes gaming even more convenient and accessible. The Game Bar feature provides quick access to essential information, such as current settings, performance statistics, and the ability to adjust image options. This allows for on-the-fly display parameter modification, which is extremely useful during intense gameplay. Despite lacking support for Dolby Vision, the S90D still offers excellent HDR image quality, allowing for full utilization of the potential of games and movies. As a result, the S90D represents a unique combination of modern technologies, outstanding image quality, and intuitive features, perfect for any gaming enthusiast.

TCL A300 is a television designed not only to transport us to a digital art museum but also to a full-fledged gaming world. Here, we find practically everything one could expect from gaming equipment: two full-bandwidth HDMI 2.1 ports, 144 Hz refresh rate, VRR support, and ALLM.

The proper implementation of the HGIG mode also deserves praise – something that competitor Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which older console or PC owners will appreciate.

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