TCL P755 vs Samsung U8000F (IPS)

TCL P755 provides average HDR effect quality. The maximum brightness of the TV is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, affecting the overall impression of contrast. However, the TV offers wide coverage of the DCI P3 colour gamut, reaching about 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

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.

The colour reproduction in the P755 in "Cinema" mode, although it is the best factory setting, leaves much to be desired. The biggest issue is the white balance, where the chart clearly shows a spike in the red colour and a drop in the green colour. This leads to a shift in colours towards red, causing the colours on the screen to appear less natural and may look incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed shifted towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows significant fluctuations, particularly in the dark areas of the image, where values drop below the optimal level of 2.4. As a result, darker areas may be displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, sits slightly above the reference curve. The graph shows a slight increase in brightness to about 50%, after which there is only a minor drop. This leads to excessive brightness enhancement in the mid-range of the image and may result in loss of detail and distortion in brighter scenes.

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, the colour reproduction on the television significantly improves when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the dip at the beginning of the graph to the values is still present, the overall accuracy of colour reproduction is much better. The “Colour Checker” test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvements in HDR content. The white balance has been corrected, translating to more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and preserving more details.

Although the image from the device does not achieve full perfection, calibration brings significant improvement. After adjusting the settings, the television performs much better, offering more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

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.

The “Gradual Smoothing” function works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which can affect the quality of tonal gradation in higher dynamic range materials.

In the case of image scaling, the television does not perform its best. There are noticeable edge cut-offs, particularly evident on the model's figure and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Additionally, SD quality image is displayed with slight cropping at the top as well as the bottom.

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".

The television offers decent, though not perfect, results in terms of motion smoothness. In the case of movies, the television has a "Flicker Reduction" feature that allows for adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the image appearance to cinema or more theatrical preferences (with lower or higher speed).

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.

The device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the TV to low latency mode, significantly improving responsiveness to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating the tearing effect and providing smoother gameplay. Dolby Vision for gamers enhances picture quality by offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as response time.

However, the TV has some limitations. The 60 Hz panel prevents the display of signals with higher refresh rates at different resolutions, which may affect the fluidity of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact the quality of gameplay on a computer. It is also worth noting that the HGiG mode, which aims to improve image quality in HDR games, does not work correctly on this model, negatively affecting the visual experience in HDR-supported 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.
