TCL P755 vs Samsung S85D

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.

Brightness is a key parameter in televisions, and the S85D Samsung model offers levels comparable to other OLEDs from a few years ago. Although it does not impress in this regard, its enormous advantage is the very competitive price. A peak brightness of 600 nits ensures good image quality in HDR conditions, giving users a taste of cinematic experiences in the comfort of their home. However, as with many budget OLED models, the biggest issue is very bright, full-screen scenes – in such moments, like the final scene from the film “The Meg,” the television can lose even half of its brightness, which is noticeable compared to more expensive OLED models. Despite this, the television offers impressive coverage of the DCI-P3 colour palette at 99%, allowing for vibrant and accurate colours to be displayed.

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 Filmmaker mode on the Samsung S85D does offer quite good factory settings, but it is not free from errors, particularly evident in colour reproduction. The white balance chart for HD and HDR content shows clear issues – both red and blue colours are significantly weakened, leading to a dominance of green. The result is an unnatural yellowish hue that can affect the perception of realistic scenes. The Color Checker test clearly shows that the colour samples deviate from expected values – for HD material, the colours can be overly saturated, with a noticeable shift towards green, which is also evident in the white balance chart. Conversely, for 4K HDR content, the colours appear too dull, lacking depth, making the image less appealing and natural. This effect is particularly noticeable in delicate scenes where colour precision plays a key role, which can be disappointing for discerning viewers who expect faithful reproduction of details and colour intensity.

As for brightness, the gamma chart for HD content looks quite good; however, there is a noticeable jump at the end, exceeding a value of 2.4. While this is not a major issue in most scenes, in more demanding sequences it may affect the clarity of bright details. For 4K content, the EOTF curve, responsible for delivering brightness, turns out to be problematic. The initial part of the chart shows a small jump. This phenomenon can result in excessive boosting of brightness in the brightest areas of the image, leading to loss of detail in very bright scenes.

Although Samsung S85D offers quite decent factory settings, especially in Filmmaker mode, it is worth considering manual adjustment of settings to improve some imperfections, particularly in colour reproduction.

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.

After calibration, the Filmmaker mode on the Samsung S85D truly impressed. The white balance, regardless of the type of content, has significantly improved, resulting in more natural colours. The Color Checker test shows that colour reproduction errors are now minimal and rarely exceed acceptable values, which indicates accurate colour rendering. The factory colour reproduction left much to be desired, but the situation has now significantly improved – the colours are natural, precise, and look as if they were rendered exactly according to the creators' intentions. This is a huge step forward compared to previous generations, where colours were often distorted or too intense.

The brightness characteristics also benefited from the calibration – it is now more vivid and precise. The gamma, although fairly good previously, has become even more stable, providing a deeper, more natural image. The EOTF curve has been aligned, allowing details in dark areas to be more visible and the contrast more balanced. With all these improvements, the television delivers an image close to reference quality, greatly enhancing the enjoyment of watching films and HDR content.

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.

Samsung S85D performs excellently in scaling images and smoothing tonal transitions. Like in other Samsung models, the television offers three noise reduction modes: off, standard, and high. Although it effectively improves gradations, it unfortunately also removes film grain, which many viewers desire to give the image a cinematic character. This grain often adds authenticity and a certain rawness to films, which is lost after smoothing. Removing the grain can make the image look too sterile and smooth, which detracts from the charm of the original film material. When it comes to scaling images, the Samsung S85D handles lower resolution content beautifully – the model in the picture and the branches in the background were displayed correctly, with no major issues with edge aliasing. The only noticeable drawback is the presence of overscan, which can sometimes cut off parts of the image, which may not please everyone.

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).

As befits an OLED television, Samsung S85D offers excellent motion fluidity. Equipped with a 120 Hz panel and fast response time, the television provides very smooth playback of dynamic scenes without visible ghosting. For movie enthusiasts, there is a feature called "Image Clarity Settings," which allows adjusting the fluidity of the image to individual preferences on a 10-point scale. Motion blur reduction enhances the sharpness of rapidly moving objects, while motion smoothing smooths out movement, eliminating the "judder" effect. This way, every user can set the appropriate level of clarity that best suits their taste, from a more cinematic effect to sharper, smoother movements.

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.

Samsung S85D OLED is an excellent choice for gamers, thanks to its many modern features that facilitate and enhance gameplay. The television has four full-bandwidth HDMI 2.1 ports, allowing you to connect the latest consoles without worrying about image quality or frame rate limitations. This means support for 4K resolution at 120 Hz, which is ideal for modern titles. Additionally, the Samsung S85D has an ALLM (Auto Low Latency Mode) feature that automatically activates low latency mode when it detects a gaming device. This means you don’t have to manually switch settings – the television takes care of ensuring a fast response time, which is crucial in games where every second counts.

The VRR (Variable Refresh Rate) feature and G-Sync support are additional elements that make gameplay smoother. VRR adjusts the refresh rate to the number of frames generated by the console or computer, eliminating screen tearing and stuttering. This is particularly useful in dynamic games where the frame rate can fluctuate. Auto Motion Plus Game is a feature that Samsung has introduced with gamers in mind, and it is worth appreciating. With it, the image in games becomes smoother – 30 frames per second look like 45, and 60 Hz gains in fluidity, creating an effect close to 90 Hz. At the same time, there is no significant increase in input lag, which remains below 25 ms, making this feature stand out among others available on the market. Gamers can enjoy a smoother image without worrying about a decline in responsiveness.

Samsung has also ensured something extra – the television has a built-in Xbox Game Pass app, which means you can play in the cloud without needing to own a console. This is a great solution for those who want to enjoy gaming without investing in additional hardware. All you need is internet access, and you have a huge library of games at your fingertips. This makes Samsung S85D a fantastic choice for both casual gamers and those who are more advanced.
