TCL A300W NXTVision vs Samsung The Frame 2026 (LS03H)

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 Frame 2026 is a genuinely bright TV. Its peak brightness reaches around 650 nits and, importantly, it maintains similar levels regardless of the type of scene being displayed. It doesn’t really matter whether we’re watching a very bright full-screen image or just a small highlight occupying part of the screen. The backlight remains powerful, allowing bright parts of the image to stand out clearly.

This gives The Frame a solid foundation for HDR. Bright highlights can look impactful, and the picture doesn’t appear flat or overly dim. Unfortunately, there is a compromise. Without local dimming, the TV cannot darken the black areas surrounding very bright objects.

This is clearly visible in scenes 2 and 4 of our test procedure. Bright elements look impressive, but at the same time, the blacks around them become noticeably raised. As a result, the image loses some of its depth, especially when watching in a dark room. This is why The Frame performs best with HDR in bright and moderately bright scenes, where its high brightness works to its advantage. In darker scenes, the situation is quite the opposite.

Colours

The Frame also performs well when it comes to colour reproduction. As a QLED TV, it can display a wide colour gamut and produce rich, saturated colours. DCI-P3 coverage reaches around 94%, while BT.2020 comes in at around 72%. These are good results, and you can see the difference in actual content.

Colours look vivid without appearing washed out, particularly in bright and colourful scenes. Animations and other content with plenty of saturated colours can look really good on The Frame. With this type of material, the TV shows one of its stronger sides.

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.

For assessing the factory colour setup we chose the Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to reproduce films and TV shows as faithfully as possible. The TV then turns off most additional image enhancers, and the colours and luminance response are intended to be as close as possible to what the creators intended. And it must be said that The Frame 2026 performs quite well in this respect straight out of the box. The biggest deviation is seen in the white balance. As brightness increases, blue starts to fall short and there’s a slight increase in green. As a result, the image shifts towards warmer tones. So white isn’t perfectly neutral, and in some scenes you can notice a subtly warmer cast.

The luminance response, both gamma and EOTF, looks pretty good. Through most of the range they stay fairly close to the target, although larger deviations are visible in the darkest parts of the image. In practice, some shadow details emerging from black may therefore be a bit more pronounced. However, it’s not an error that jumps out during normal viewing. Overall, Filmmaker Mode is a good starting point here. However, the factory picture is a bit too warm and not all hues land exactly where they should.

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 calibration we mainly managed to remove that warmer tint and better even out the white balance. We also smoothed the brightness response a bit, which made the picture more neutral and predictable. There are, however, things calibration won't fix. It's mainly the black performance, which comes from the backlight design and the lack of local dimming. In some scenes the blacks will therefore still be slightly lifted, and you just have to accept that. It's more a characteristic of this model than something you can fix with the settings. HDR is also somewhat limited. Samsung doesn't give full freedom to work across the widest colour gamut here, so not all colours can be reproduced perfectly. In normal viewing it will probably be hard to notice, but it's worth being aware of.

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.

As with many of Samsung’s newer TVs, this one also uses the NQ4 AI processor, albeit the older, second-generation version. I must admit it handles digital image processing quite well. Lower-resolution material is sharpened effectively, and when upscaled to 4K it still looks natural. The TV can also tidy up weaker sources a bit, such as older recordings or lower-quality broadcasts. That doesn’t, of course, mean it will suddenly turn poor footage into true 4K, but at close viewing distances the difference compared with simpler models with weaker processors is easy to spot. Edges are clearer and fine details aren’t lost as much to signal compression.

Samsung also provides a few extra picture-enhancing features, but as usual it’s best to use them sparingly. At stronger settings, noise reduction can very effectively reduce posterisation, but it also noticeably interferes with the image. The picture then starts to look quite artificial, for example by heavily smoothing faces. So these features make most sense with really poor sources when all the noise is very distracting.

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.

Samsung again used a panel here with a maximum refresh rate of 144 Hz. Refresh rates up to 120 Hz mainly offer greater flexibility with high-motion content. The TV can use additional motion smoothing systems that can improve smoothness in sports and other fast-paced content. However, a high refresh rate alone does not solve everything. The Frame still uses a VA panel, which has a fairly slow response time, resulting in quite pronounced motion blur. With fast-moving objects, especially against dark backgrounds, the trails are easy to notice. There's also a slight double-imaging of edges, which can be visible even after turning off additional motion enhancement systems. We already saw similar behaviour in last year's The Frame 2025, and it's a shame Samsung hasn't fixed this. The 144 Hz itself provides a good foundation, but the panel's response time still limits this TV.

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.

When it comes to gaming features, The Frame is practically on par with Samsung’s flagship TVs. Once a console is connected, the TV automatically switches to Game Mode thanks to ALLM, so there’s no need to change the settings manually every time. There’s also VRR, which matches the screen’s refresh rate to the frame rate generated by the console or PC. When the frame rate drops, this helps prevent the characteristic screen tearing that can otherwise occur.

The Frame naturally supports 4K at 120Hz, allowing you to take advantage of higher frame rates on the PlayStation 5 and Xbox Series X. HGiG also works correctly. Once HDR has been properly calibrated on the console, the TV doesn’t try to additionally brighten the image on its own, so bright highlights in games are displayed as they should be.

Samsung also includes its Game Bar. This quick-access menu can be opened without leaving the game and lets you check things like VRR operation or the current frame rate, while also giving you quick access to the most important gaming settings. PC users get even more flexibility, as the Full HD mode mentioned earlier allows the refresh rate to be increased all the way up to 240Hz.

There is really only one feature missing, and by now it’s something we’ve come to expect from Samsung TVs: Dolby Vision Gaming. Xbox owners will notice this the most, as Xbox consoles can actually use Dolby Vision in supported games.

There is one more limitation worth mentioning that applies specifically to this model. The One Connect box has only one HDMI 2.1 port, so this is the only input you can use for a console or PC if you want to play at 4K 120Hz. Fortunately, Samsung hasn’t combined this port with eARC. This means you can connect a soundbar separately to HDMI 3 and still keep the full-bandwidth HDMI 2.1 port available for your console.
