TCL C75B vs Samsung The Frame 2026 (LS03H)

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

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 C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

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 calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

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 C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

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 C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

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.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.

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.
