TCL C75B vs Samsung The Frame 2026 (LS03H)

During our luminance test, the TCL C75B "spat out" about 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the television does not perform badly 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 as low brightness values. However, for HDR enthusiasts seeking stronger light effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the 95% coverage of the DCI-P3 color palette. This is a very good result that easily suffices to enjoy a wide range of colors in content available on popular streaming platforms. Vivid and rich colors are definitely a strong point of this model.

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 C75B offers many picture modes, but in our opinion, the best choice is the "Film" mode. Although its settings are quite good, the television struggles with certain color reproduction issues. In tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered correct. This effect was particularly noticeable in skin tones, which appeared unnaturally warm. The main culprit of this phenomenon turned out to be the white balance, characterized by an excessive amount of blue and red in both HD and 4K HDR materials.

Another issue 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, lost in total blackness (e.g., the bottom part of the screen in the comparative photo - the area around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that a similar problem 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 see how much could be extracted from this model after professional calibration. Details are described in the next section.

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 calibrating the TCL C75B, it has clearly improved in terms of color reproduction. Although the TV does not offer many options for adjusting the white balance, we were able to refine its settings significantly. As a result, the image has stopped being overly pink, and the colors now look much more natural and harmonious.

The gamma jump, which was previously a problem, has not disappeared completely, but we managed to significantly reduce it. This has made the details in dark scenes more visible – both in HD and 4K HDR material.

Unfortunately, the lack of local dimming is still noticeable. The "glowing black" effect remains, but that's a limitation of the display itself. Despite this, the colors after calibration look vastly better, and the image is much more enjoyable to watch.

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.

The TCL C75B has a tonal transition smoothing feature, but unfortunately, we can't praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature didn't work at all. It's hard to say something positive about it because, in practice, it seems completely useless.

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

Unfortunately, a bigger problem turned out to be overscan, which is the trimming of the image edges. In our tests, it happened that news tickers or other elements close to the edge of the screen were cut off. This is definitely something worth paying 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, 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.

TCL C75B definitely has something to offer gamers. The TV 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 great results, especially for a model from the budget range.

Additionally, 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-step scale, providing a lot of customization options – everyone can set the smoothness to their liking.

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.

The TCL C75B is undoubtedly a television designed for gamers. It offers almost everything that the most demanding console users need. With the implementation of full-bandwidth HDMI 2.1, the television supports features such as ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating across 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 detail representation in HDR-optimized games. The C75B is also equipped with a very convenient interface for gamers in the form of a Game Bar, where you can check all key parameters, such as refresh rate, input lag, or picture settings – all within one click's reach.

In a nutshell: the C75B is an excellent choice for gamers, offering a wide range of features that allow for fully enjoying the capabilities of modern consoles and games.

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.
