TCL C75B vs Samsung U8000F (IPS)

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.

Better does not mean good – and that perfectly summarizes the capabilities of the U8092F when it comes to displaying bright movie scenes in HDR mode. The brightness of the panel is just under 250 nits, which is definitely too little to enjoy any lighting effects. An interesting situation was noted during the measurement of the fourth scene from the movie Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which are still weak). One could even suggest that the device uses some form of "global dimming," but unfortunately, the results are still very poor. To make matters worse, the television does not support a wide color gamut – the coverage of the DCI-P3 space is about 80%, so there’s no hope for truly vibrant colors. HDR images here look rather like lightly brightened SDR, and that's the form we would suggest sticking to when it comes to this television.

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.

The Samsung U8000F was tested in the best possible picture mode built into the TV, which is Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference-quality image without unnecessary enhancements. For SDR content (mainly HD/SD), the TV performed surprisingly well straight out of the box. White balance errors hovered around a value of 3, which is roughly at the threshold of perception. The only complaint could be about brightness management – the gamma chart showed a slight tendency to brighten or darken certain areas, but overall it performed quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance wasn't terrible, the TV had significant color errors – particularly noticeable on the Color Checker chart, where almost every sample landed outside the target point. The HDR image simply looks unnatural, and colors can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide color gamut (DCI-P3). The TV is physically incapable of displaying accurate colors in HDR standard – and this unfortunately shows in every more demanding material.

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.

Although the U8000F offered quite a decent picture in SDR right out of the box, we were able to adjust it a little more. We managed to eliminate a slightly purplish tint and calibrate the gamma to a more reasonable level. However, the television still tends to overemphasize the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is difficult to completely correct.

Unfortunately, the situation looks worse in HDR. It's hard to talk about any significant improvement here – the television is simply not designed for HDR content. We tried to adjust the picture in the advanced settings, but despite everything, the color errors remained quite large – a delta E above 7 indicates noticeable deviations. It's a bit of a shame, but that's the charm of a budget design. In SDR, the U8000F performs just fine, while HDR is simply not its league.

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.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup.

This year's model is equipped with a function to improve the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but even so – it can be confidently said that it works effectively.

However, not everything went perfectly. The U8000F has noticeable issues with slight frame cutting when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly “cut off.”

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.

The Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it’s clear that we shouldn’t expect any miracles. This is simply the standard in this class – sufficient for everyday viewing, but without any fireworks.

The TV offers one motion smoothing slider – a feature called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in movies. Higher settings provide a more "theatrical" and smoothed effect, while lower settings help retain the original character of the film with a slight 24p effect. Interestingly, there is a feature called "Clear Motion LED", which is a BFI mode – that inserts black frames between the frames of the picture to improve motion clarity. However, in practice, the screen flickers significantly when activated, and it should be regarded more as an experiment than something that realistically enhances gaming comfort.

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.

Samsung U8000F offers a basic set of features for gamers, which nonetheless may be sufficient for less demanding users. We have an automatic game mode here – when a game is launched on the console, the TV automatically switches to low latency mode, which significantly improves response time. We also find the VRR feature, or variable refresh rate, which operates within a range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the "tearing" effect, as long as we stay within this range.

And unfortunately, that's about it for the advantages. Add-ons like Game Bar or higher refresh rates are reserved for the higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust HDR images to the intentions of game developers. Unfortunately – even though this feature appears in promotional brochures and store materials – its configuration on the Xbox console turned out to be... impossible in practice.
