TCL P755 vs Samsung Neo QLED QN70F / QN74F / QN77F

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.

QN70F is a television that can positively surprise when it comes to brightness. In ideal testing conditions, it reaches even 800 nits, which – for this price range – is a really solid value. Of course, that’s a result from test patterns, so we decided to check how it performs in practice, on real films. Here, the television somewhat tempers its capabilities. In most of the tested scenes – e.g. in "The Meg" – the actual HDR brightness remained around 500 nits. That’s still a decent result, allowing you to enjoy HDR effects, although it’s far from perfection. On the other hand, we have a QLED screen with a quantum dot layer, which means very good colour reproduction capabilities. Colours are vivid and saturated. QN70F covers about 94% of the DCI-P3 colour space, and in the wider BT.2020 palette, it exceeds 75%, so in this respect, there’s nothing to be ashamed of.

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.

We tested the QN70F in the best default picture mode, which is Filmmaker Mode. And it must be admitted that in this particular test unit, the factory settings performed quite well. The picture was calm, natural, and despite slight deviations – pleasant to watch. The biggest error was a slight dominance of red in the white balance, which caused a slight pinkish tint over the entire scene. However, it wasn't a glaring flaw – rather subtle and only noticeable when directly compared to a properly calibrated screen. A slightly bigger issue arose in the brightness characteristics. The TV tends to lower the brightness of parts of the image that should be displayed brighter. As a result, some details can appear slightly dimmed – they don't completely disappear, but they don't stand out as clearly as they should. Nonetheless, as for a TV in this range and in these settings – we consider the result a good starting point for further calibration.

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.

After calibration, the QN70F shows that it can offer a really high level of colour reproduction. It has managed to nearly perfectly balance the white point, and the values in the Color Checker test dropped below level 3 – that is, below the threshold at which the average eye can notice differences. The image looks natural, and the colours are faithfully reproduced, without excessive saturation or the coolness known from factory settings. It must be acknowledged that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after appropriate settings, can come close to significantly more expensive models in terms of colour accuracy. The only thing that could still be picked on is the brightness characteristic. There is still a tendency to brighten the smallest sections of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final result definitely deserves recognition.

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.

Samsung QN70F offers a distortion reduction feature that improves the smoothness of tonal transitions. In "Standard" mode, it works quite well – smoothing out problematic transitions without significantly interfering with the structure of the image. Film grain is partially removed, but details like texture and skin structure remain visible. "High" mode operates much more aggressively. The smoothing is stronger, but at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or turning off this feature altogether. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to upscaling low-quality content, the QN70F performs very well. Tests with lower resolution images went really well. Despite some slight aliasing of contours, everything looks clean and clear, even if the original content was very poor quality. It's just a pity that the television has an overscan issue that cannot be completely turned off. As a result, images with very low resolution may be slightly cropped, which is mainly noticeable on subtitles or the interface.

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).

The QN70F is a television with a refresh rate of 144 Hz, which in itself places it among the best when it comes to image smoothness. Whether we're watching fast-paced sports broadcasts or gaming on a console – the picture looks fantastic. There's no sense of stuttering, clipping, or the typical "judder" seen in lower-end models during fast motion. Samsung also allows you to adjust the smoothness to your own preferences. In the picture clarity settings, we find options such as motion blur reduction and judder reduction – each of which can be adjusted independently. This is especially useful when we are watching content with a lower frame rate and want to give it a smoother, more cinematic feel – or conversely, maintain the natural filmic "feel" of 24 frames.

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 QN70F is a really solid choice for gamers. It features four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at 144 Hz refresh rate. Plus, it has all the basic features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar that displays information about the mode, resolution, and frame rate.

The Game Motion Plus feature is also worth noting, as it allows for the addition of artificial frames to games running at 60 fps or less. It works surprisingly well and improves gameplay smoothness in many titles—especially in those where consoles struggle to maintain a stable frame rate—without significant latency.

Unfortunately, there are some drawbacks. The lack of support for Dolby Vision mode is not surprising—it’s a standard for Samsung. However, the absence of the HGiG feature is far more disappointing. Worse still, it was removed in a software update, which might catch users who previously relied on it off guard. Without HGiG, one cannot manually set the maximum HDR brightness from the console, resulting in some games looking slightly overexposed—especially if the TV misinterprets the tonal range. Why Samsung, a brand that has set the standards for gaming features for years, decided to take such a step is hard to say. At the time of writing this review, the tested TV was running on software version 1110—and frankly, if you care about full support for gamers, it’s better to hold off on updates for now.
