TCL P755 vs Samsung U8000F (IPS)

TCL P755 provides average HDR effect quality. The maximum brightness of the television 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, which affects the overall impression of contrast. However, the television offers a wide coverage of the DCI P3 colour gamut, reaching around 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 does not mean good – and that is exactly how to summarise the capabilities of 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 light effects. An interesting situation was observed during the measurement of the fourth scene from the film Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which remain weak anyway). One might even suggest that the device is using some form of 'global dimming', but unfortunately – the results 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 one cannot expect truly vibrant colours. The HDR image here looks more like a slightly brightened SDR, and it is this form that we would suggest sticking to when it comes to this television.

The colour reproduction in the P755 in "Movie" mode, although it is the best factory setting, leaves much to be desired. The biggest problem is the white balance, where the graph clearly shows a spike in red and a drop in green. This leads to a shift in colours towards red, making the colours on the screen less natural and potentially looking 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 skewed towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows considerable fluctuations, particularly in dark areas of the image, where values drop below the optimal level of 2.4. This results in darker areas being displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, is slightly above the reference curve. The graph shows a slight boost in brightness to around 50%, followed by only a minor decrease. This leads to excessive brightness enhancement in the mid-tones of the image and may result in loss of detail and distortion in brighter scenes.

The Samsung U8000F has been tested in the best possible picture mode built into the television, namely Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference picture without unnecessary enhancements. In the case of SDR content (mainly HD/SD), the television, out of the box, showed itself surprisingly well. Errors in white balance hovered around a value of 3, which is roughly on the edge of perceptibility. The only complaint could be about brightness management – the gamma graph showed a slight tendency to lighten or darken certain sections, but even so, the overall performance is quite good 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 in the Color Checker graph, where almost every sample hit outside the target point. The picture in HDR simply looks unnatural, and the colours can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide colour gamut (DCI-P3). The television is physically unable to display correct colours in the HDR standard – and unfortunately, this is felt in every more demanding material.

After calibration, the colour reproduction on the television improves significantly when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the drop at the beginning of the graph to value 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 improvement in HDR content. The white balance has been improved, resulting in a 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 tonal quality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and retaining more detail.

Although the device's picture does not achieve complete perfection, calibration brings significant improvement. After adjusting the settings, the television presents itself much better, offering a 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.

Although the U8000F already offered a fairly well-balanced image in SDR straight out of the box, we were able to refine it a bit further. We managed to eliminate a slight purple tint and adjust the gamma to a more sensible level. However, the television still has a tendency to overexpose the smallest and brightest parts of the image – the gamma chart shows a characteristic 'dip' that is difficult to completely straighten out.

Unfortunately, the situation is worse in HDR. It's hard to speak of any significant improvement here – the television is simply not designed for HDR content. We tried to correct the image in the advanced settings, but despite our efforts, the colour errors remained substantial – a delta E above 7 indicates very noticeable deviations. It's a bit disappointing, but that's the nature of budget construction. In SDR, the U8000F performs reasonably well, whereas HDR is just 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 may affect the quality of tonal gradations in higher dynamic range materials.

When it comes to image scaling, the television does not perform at its best. There are noticeable edge cuts, particularly evident on the figure of the model 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. Moreover, SD quality images are 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 – namely the DU7192 model, which theoretically occupies the same spot in the range.

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

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

The television offers decent, although not perfect, results in terms of motion fluidity. For films, the television features a “Flicker Reduction” function that allows for motion fluidity adjustment on a scale from 1 to 10. With this option, we can customise the appearance of the image to a cinematic or more theatrical preference (with a slower or faster pace).

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

The television offers a single motion smoothing slider – a function called “Motion Blur Reduction”, which allows us to adjust the smoothness of the image in films. Higher settings provide a more “theatrical” and smoothed effect, while lower settings maintain the original character of the film with a slight 24p effect. An interesting feature is “LED Clear Motion”, which is a BFI mode – that inserts black frames between frames of the image to improve motion clarity. However, in practice, the screen flickers quite a bit when this feature is activated, and it should be regarded more as an experiment than something that genuinely enhances the comfort of gaming.

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 television to low latency mode, significantly improving response 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 screen tearing and providing smoother gameplay. Dolby Vision for gamers enhances picture quality, 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 reaction time.

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

The Samsung U8000F offers a basic set of features for gamers, which may still prove sufficient for less demanding users. It includes an automatic game mode – upon launching a game on the console, the television automatically switches to low latency mode, significantly improving response times. We also find a VRR feature, meaning variable refresh rate, which operates within a range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the effect of screen tearing – provided, of course, we stay within this range.

Unfortunately, that is about it when it comes to advantages. Add-ons like Game Bar or higher refresh rates are reserved for higher models of Samsung's 2025 line. In theory, the television also supports the HGiG function, which should adjust HDR images to the intentions of game developers. Unfortunately – despite this feature appearing in brochures and retail materials – its configuration on the Xbox console has proven to be... impossible in practice.
