TCL C75B vs Samsung The Frame 2026 (LS03H)

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 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 various picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the TV struggles with certain colour reproduction issues. In tests, we noticed that the image had a noticeably pinkish hue compared to what could be considered correct. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit of this phenomenon turned out to be the white balance, characterised by an excess of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was reproduced. 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 black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

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 calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant 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 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 C75B has a feature for smoothing tonal transitions, but unfortunately, we cannot praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature wasn’t working at all. It’s hard to say anything positive about it, as in practice it seems completely useless.

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

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 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 budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

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.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.

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.
