TCL C75B vs Samsung U8000F (IPS)

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.

Better doesn't mean good – and that's exactly how you can sum up 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 low to enjoy any light effects. An interesting situation was observed during measurements 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 still remain weak). One could even suggest that the device employs some form of "global dimming," but unfortunately – the effects are still very poor. To make matters worse, the television does not support a wide colour gamut – the coverage of the DCI-P3 space is around 80%, so don’t count on truly vibrant colours. The HDR image here looks more like slightly brightened SDR, and that’s the approach we would suggest you stick to when it comes to this television.

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.

Samsung U8000F has been tested in the best possible built-in picture mode on the television, which is Filmmaker Mode. This mode should – at least in theory – provide a cinematic, reference image without unnecessary enhancements. For SDR content (mainly HD/SD), the television presented itself surprisingly well out of the box. White balance errors hovered around a value of 3, which is roughly on the edge of perceptibility. The only criticism could be directed at brightness management – the gamma chart showed a slight tendency to brighten or darken certain sections, but overall it performs quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance was not terrible, the television had significant colour errors – particularly evident on the Color Checker chart, where almost every sample fell outside the target point. The image in HDR simply looks unnatural, and the colours can be shifted, muted, or too cool. This largely stems from the fact that U8000F does not support a wide colour gamut (DCI-P3). The television is physically unable to display correct colours in the HDR standard – and this is unfortunately felt in every more demanding material.

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.

Even though the U8000F already offered a fairly good picture in SDR straight out of the box, we managed to tweak it a bit more. We were able to remove a slight purple tint and adjust the gamma to a more reasonable level. However, the television still tends to over-brighten the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is hard to fully straighten out.

Unfortunately, the situation looks worse in HDR. It's difficult to talk about any significant improvement here – the television simply isn't designed for HDR content. We tried to adjust the picture in the advanced settings, but despite our efforts, the colour errors remained quite noticeable – a delta E above 7 is already significantly visible deviations. It's a bit unfortunate, but that's the charm of a budget build. In SDR, the U8000F performs reasonably, whereas HDR is simply not its league.

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.

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

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

However, not everything has gone perfectly. The U8000F has noticeable issues with slight frame stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must be aware that the picture may appear slightly "choppy".

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

The television 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 ones maintain the original character of the film with a slight 24p effect. An interesting feature is “Clear Motion LED”, or BFI mode – which inserts black frames between the image frames to enhance motion clarity. However, in practice, the screen flickers significantly when it's activated, and it's better viewed as an experiment rather than something that truly enhances gaming comfort.

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.

Samsung U8000F offers a basic set of features for gamers, which may still be sufficient for less demanding users. It has an automatic game mode – when a game is launched on the console, the TV automatically switches to low latency mode, which significantly improves response time. It also includes a VRR function, or variable refresh rate, which works within the range of 48 to 60 Hz. This means that both Xbox and PS5 won't produce the "tearing" effect – as long as we stay within this range.

And unfortunately, that's about it for the advantages. Additional features like Game Bar or higher refresh rates are reserved for higher models of Samsung’s 2025 line. In theory, the TV also supports the HGiG function, which should adjust the HDR image to the intentions of game developers. Unfortunately – although this function appears in brochures and store materials – its setup on the Xbox console turned out to be... impossible in practice.
