TCL A300W NXTVision vs Samsung S90H (WOLED)

When it comes to brightness, the TCL A300W is definitely the dimmest TV among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, you can see that right away. In our measurements, peak luminance reached only around 400 nits, and on test movie screens, this value dropped to 350 nits. That’s definitely too little to feel the real "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 colour gamut, both DCI-P3 and BT.2020. In addition, 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 experience of materials in this quality.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although it is slightly dimmer compared with the QD-OLED version. That difference is not as pronounced as in last year’s F series, where gaps sometimes reached 500 nits. Here the parameters of both panels are very similar, with differences in peak brightness of only about 100–150 nits. In small-window measurements the S90H with the WOLED panel easily reaches close to 1,500 nits. That headroom lets it phenomenally convey the dynamics of HDR effects — blooms, light reflections and explosions have the right punch, exactly as intended by the studio creators. As with most OLED displays, when a very bright scene fills the entire screen, panel protection systems kick in and brightness naturally falls to around 700 nits. It’s worth stressing that this is still an excellent result on the market, often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, very high-brightness colours don’t achieve quite the same saturation, and the wide-colour volume is slightly more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches almost 99%, meaning that for the vast majority of real film scenes both variants will present an almost identical image. The real gap only appears in rarer, especially demanding productions that use the ultra-wide BT.2020 gamut. Because of the WOLED panel’s construction, coverage of that standard is roughly 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit HDR colours may appear a touch less vivid.

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

The management of brightness is also lacking. In the case of older HD materials, the image often seems too dark – confirmed by an elevated gamma value. Conversely, with HDR content, the effect is the opposite – the image is overly bright, as we observed in scenes from the film Pan. Such a lack of consistency also affects colour accuracy – a test with a ColorChecker showed that many samples clearly deviate from 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.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the annoying oversaturation seen in more aggressive profiles. However, as is often the case without full calibration, there is unit-to-unit variation. In our test the white balance was a little deficient in the blue component, so the image leaned slightly towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at around 2.2, which caused a small lift in shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

After our professional calibration, the TCL A300 has literally been given a new lease on life. The image has stopped being too warm, and the colours finally look as they should – as confirmed by the ColorChecker test, where the colour 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 can't be bypassed – a slightly visible 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 whole new quality.

After full calibration, you can safely say the S90H in the WOLED version looks almost perfect. In SDR mode colour errors fall to ultra-low levels and Delta E values very rarely exceed 2. That's a phenomenal result, so if perfectly faithful colour reproduction matters to you, it's definitely worth getting it calibrated. The calibrated HDR mode also performs very well, where the white balance was stabilised and previous deviations eliminated. After professional tuning it's really hard to fault anything, because the TV delivers an image with almost exemplary naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the saturation limitation in extremely bright scenes, while the tuning potential and colour fidelity are at the highest level.

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

Image scaling is also not one of A300's strong points. On 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 TV does not cut off the image and has no issues with overscan, but the overall quality of scaling is rather average.

When it comes to banding reduction itself, Samsung has kept the same solutions known from last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that’s somewhat more prone to banding. However, it’s important to remember it acts aggressively. This mechanism, aside from the artefacts themselves, can remove fine film grain and subtly soften detail. Ultimately it’s a trade-off, but if you want perfectly faithful image reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so upscaling quality was almost identical. The chip sharpens lower-resolution material very well, pulling a satisfying level of detail out of it. However, Samsung still hasn’t solved the old overscan problem. For some older recordings or archival footage the edges of the image can be slightly cropped. It’s a minor drawback, but it’s a shame the manufacturer still hasn’t fixed it.

TCL A300 is equipped with a 144 Hz panel, which should instantly satisfy virtually everyone - both gamers and sports fans. Motion is fluid and the image is clear even during fast scenes. Additionally, the television offers a motion enhancement feature 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, filmic look with visible frames to a very smooth (though already unnatural) image reminiscent of a soap opera effect. This way, everyone can find a setting that suits them.

When it comes to motion handling the S90H is simply excellent. This year's panel offers its refresh rate boosted to 165 Hz, although in practice the benefit will mainly be for gamers connecting a powerful PC. For movies, TV series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, the OLED panel's lightning-fast response time does the job. Motion is clean, and the ghosting or smearing seen on LCDs simply doesn't occur here.

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

It also deserves credit for the proper implementation of the HGIG mode – something that competing Hisense sometimes struggles with. The television handles lower resolutions (e.g., Full HD) with ease while maintaining high refresh rates, which will be appreciated by owners of older consoles or PCs.

Additionally, there's an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is indeed well-prepared for gaming at the highest level – it’s just a shame that issues with ghosting somewhat detract from its overall appeal as a gaming device.

Gamers should feel right at home with the S90H, because Samsung has left few reasons to complain in this area. The TV has four HDMI 2.1 ports, each supporting VRR, ALLM and high refresh rates. There's also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG. In last year's models it could cause issues when used with a console, but on the S90H it now works as it should. What really stands out against the competition is Game Motion Plus. It's a specialised motion-smoothing mode for games that works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother and latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That's important, because on many TVs enabling a similar smoothing feature causes such a big increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There's still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be the more useful feature.
