TCL A300W NXTVision vs Samsung The Frame 2026 (LS03H)

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 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 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.

For assessing the factory colour output we chose the Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to reproduce a film or series as faithfully as possible. The TV then switches off most of the extra picture enhancement features, and the colours and luminance characteristics are intended to be as close as possible to what the creators of the material intended. And it must be admitted that The Frame 2026 performs really well in this respect straight out of the box. The biggest deviation is visible in the white balance. As brightness increases the blue starts to drop out and green increases slightly. As a result the picture shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer cast.

The luminance response for both the gamma and EOTF curves looks good. Across most of the range they stay fairly close to the target, although in the darkest parts of the picture there is a larger deviation. In practice some details emerging from black may therefore be rendered a little more strongly. However, this is not an error that stands out during normal viewing. Overall Filmmaker Mode is a good starting point here. However the picture is a little too warm by default and not all hues land exactly where they should.

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.

After calibration we mainly managed to remove that warmer tint and better even out the white balance. We also smoothed the brightness response a little, which made the picture more neutral and predictable. There are, however, things calibration won't fix here. It's mainly the black behaviour, which stems from the backlight design and the lack of local dimming. In some scenes blacks will therefore still be slightly lifted and you simply have to accept that. It's more a characteristic of this model than something that can be fixed with the settings. HDR is also a limitation. Samsung doesn't allow full freedom when working with the widest colour gamut, so not all colours can be reproduced perfectly. In normal viewing it's probably 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 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.

As with many of Samsung’s newer TVs, this one also uses the NQ4 AI processor, only the older, second-generation version. And you have to admit it handles digital image processing quite well. Lower-resolution material is sharpened effectively, and after upscaling to 4K it still looks natural. The TV can also somewhat "tidy up" weaker sources, like older recordings or lower-quality broadcasts. That doesn't, of course, mean it will suddenly turn poor footage into 4K, but at closer viewing distances the difference compared with simpler models with weaker processors is easy to spot. Edges are clearer, and fine details don't get lost as much to signal compression.

Samsung also offers a few additional image-enhancing features, but as usual it's best to use them sparingly. At stronger settings, noise reduction can very effectively reduce posterization, but it also noticeably interferes with the image. The picture then simply starts to look very artificial, for example by heavily smoothing characters' faces. So it makes the most sense with really poor sources when various types of noise are seriously distracting.

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.

Samsung again used a panel with a maximum refresh rate of 144 Hz. Refresh rates up to 120 Hz primarily offer greater possibilities with material that contains a lot of motion. The TV can use additional motion-smoothing systems that can improve fluidity in sports and other fast-moving 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, and consequently fairly pronounced motion blur. With rapidly moving objects, especially on a dark background, trails are easy to notice. There is also a slight doubling of edges, which can be visible even when additional motion-enhancement systems are switched off. We saw similar behaviour in last year's The Frame 2025, and it's a shame Samsung hasn't addressed this issue. The 144 Hz itself provides a good foundation, but the panel's response time still limits this TV.

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.

In terms of gaming features, The Frame is practically on a par with Samsung’s top televisions. When a console is connected the TV automatically switches to Game Mode thanks to ALLM, so we do not have to change settings manually each time. There is also VRR, which matches the screen refresh rate to the number of frames produced by the console or PC. This helps avoid the characteristic screen tearing when frame rates drop. The Frame of course supports 4K at 120 Hz, so you can take advantage of the capabilities of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR properly configured on the console, the TV does not try to brighten the picture further on its own, so bright effects in games are displayed as they should be. Samsung also includes a Game Bar. It is a handy menu you can bring up without leaving the game. There you can check VRR operation and the current frame rate, and quickly change the most important gaming-related settings. With a PC the possibilities are even greater, because the aforementioned Full HD mode lets you increase the refresh rate up to 240 Hz. There is essentially one feature missing that Samsung has already got us used to, namely Dolby Vision Gaming. Xbox owners will notice this most, as that console can use Dolby Vision in games. There is one more thing worth mentioning specific to this model. Its One Connect module has only one HDMI 2.1 port, so you must plug the console or PC into that port if you want to use 4K at 120 Hz. Fortunately Samsung did not combine this port with eARC. The soundbar can therefore be connected separately (3) and you still have a full HDMI 2.1 available for the console.
