TCL A300W NXTVision vs Samsung The Frame 2026 (LS03H)

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.

The Frame 2026 is genuinely a bright TV. Its peak brightness reaches about 650 nits and, importantly, similar values are maintained regardless of the type of scene being displayed. So it doesn’t matter much whether we’re watching a very bright full-screen shot or just a small bright element occupying part of the screen. The backlight always has a lot of power, so bright portions of the image are strongly illuminated. That gives The Frame a solid foundation for HDR. Bright highlights can stand out, and the picture doesn’t look flat or too dark. Unfortunately, this is not a solution without compromises. Because it lacks local dimming, the TV cannot darken the blacks next to very bright elements.

This is clearly visible, among other things, in scenes 2 and 4 from our test procedure. Bright areas look intense, but at the same time the blacks around them become noticeably lifted. The picture loses depth as a result, especially when watching in the evening. For that reason The Frame performs best with HDR in bright and moderately bright scenes. There the high backlight brightness works in its favor. In darker shots the situation is the opposite.

Colors

The Frame also performs well in terms of color. It’s a QLED TV, so it can display a wide color gamut and show richly saturated colors. DCI-P3 coverage is around 94%, and BT.2020 about 72%. Those are good numbers and you can see them while watching. Colors are vivid and do not look washed out. It looks best in bright, colorful scenes. Animations or cartoons with lots of saturated hues can look really good on The Frame. In such material the TV shows one of its stronger points.

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.

To evaluate the out-of-the-box colors we chose Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to present a movie or series as faithfully as possible. The TV then turns off most additional picture enhancers, and the colors and luminance characteristics are meant to be as close as possible to what the content creators intended. I have to admit that the The Frame 2026 already performs quite well in this regard straight out of the box. The biggest deviation is visible in the white balance. As brightness increases, blue starts to drop off and green increases slightly. As a result the image shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer overall cast.

The luminance response — gamma or EOTF — looks good. Across most of the range they stay fairly close to the target, though in the darkest parts of the image there is a larger deviation. In practice, some details emerging from black may therefore appear a bit more pronounced. That said, it’s not a flaw that jumps out during normal viewing. Overall, Filmmaker Mode is a good starting point here. However, the factory image is a bit too warm and not all hues land exactly where they should.

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.

After calibration we mainly managed to remove that warmer cast and better even out the white balance. We also smoothed the brightness response a bit, which made the image more neutral and predictable. However, there are things calibration won't fix. It's mainly the behavior of the blacks, which stems from the backlight design itself and the lack of local dimming. In some scenes blacks will therefore still be slightly lifted, and you'll just have to accept that. That's more a characteristic of this model than something that can be fixed with settings. HDR is also somewhat limited. Samsung doesn't give full freedom to work across the widest color gamut, so not all colors can be reproduced perfectly. In normal viewing you probably won't notice it, 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 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.

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 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.

Samsung again used a panel with a maximum refresh rate of 144 Hz here. Refresh rates up to 120Hz primarily offer more headroom for material with a lot of motion. The TV can use additional motion interpolation systems that can improve smoothness 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 relatively slow response time, and consequently fairly pronounced motion blur. With fast-moving objects, especially on a dark background, motion trails are easy to notice. There's also a slight doubling of edges, which can be visible even with the additional motion processing systems turned off. We already saw similar behavior in last year’s The Frame 2025, and it’s a pity Samsung hasn’t fixed that element. 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. 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.

In terms of gaming features, The Frame is practically on par with Samsung's top TVs. When you connect a console the TV automatically switches to game mode thanks to ALLM, so you don't have to change settings manually each time. There's also VRR, which matches the display's refresh rate to the frames being produced by the console or PC. During drops in smoothness this helps avoid the characteristic screen tearing. The Frame of course supports 4K at 120 Hz, so you can take advantage of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR set up properly on the console the TV doesn't try to brighten the image on its own, so bright effects in games are shown as they should be. Samsung also includes a Game Bar. It's a handy menu you can bring up without leaving the game. There you can check things like VRR and the current frame rate, and quickly change the most important gaming settings. For PC use the options are even greater, since the mentioned Full HD mode allows raising the refresh rate up to 240 Hz. There is really only one feature missing that Samsung has already spoiled us with, and that's Dolby Vision Gaming. Xbox owners will notice this the most, because that console can use Dolby Vision in games. There's one more thing worth mentioning that applies specifically to this model. Its One Connect module has only one HDMI 2.1 port, so that's the only port you can use for a console or PC if you want 4K 120 Hz. Fortunately Samsung didn't tie that port to eARC. You can therefore connect a soundbar separately (3) and still have a full HDMI 2.1 port available for the console.
