Samsung S85D vs TCL C655 Pro

Brightness is an important factor in televisions, and the S85D offers a level similar to older OLED models. While it’s not outstanding in this area, it comes at a very competitive price. With peak brightness at 600 nits, HDR content looks sharp, delivering a hint of cinematic quality at home. Like many budget OLEDs, though, very bright, full-screen scenes—such as the final shot in The Meg—may cause the brightness to drop by nearly half, which is noticeable compared to pricier models. However, with 99% DCI-P3 colour coverage, the S85D delivers vibrant, accurate colours.

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

The Filmmaker mode on the Samsung S85D offers the best factory settings, but it is not free from flaws, particularly noticeable in colour reproduction. The white balance chart for HD and HDR content shows clear issues – both red and blue are significantly weakened, leading to a dominance of green. The result is an unnatural yellowish glow that can affect the perception of realistic scenes. The Colour Checker test also highlights issues, with colour samples deviating from expected values – for HD materials, colours tend to be too saturated, with a noticeable shift towards green, as seen in the white balance chart. In contrast, for 4K HDR content, colours appear too dull and lack depth, diminishing the attractiveness and naturalness of the image. 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.

When it comes to brightness, the gamma chart for HD content produces positives, but there is a noticeable spike at the end, exceeding a value of 2.4. Although this is not a major problem in most scenes, in more demanding sequences it can affect the clarity of bright details. For 4K content, the problematic aspect is the EOTF curve, responsible for delivering brightness. The initial part of the chart shows a small spike. 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 the Samsung S85D’s factory settings are reasonable, especially in Filmmaker mode, it is worth considering a manual adjustment of settings to improve some imperfections, particularly in colour reproduction.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with the TCL 655 PRO model.

In the case of HD content, the white balance clearly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation looks better, but there is a tendency to excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

After calibration, Filmmaker mode on the Samsung S85D truly stands out. White balance adjustments across all content types yield significantly more natural colour reproduction. In the Colour Checker test, colour reproduction errors are minimal and well within acceptable limits, reflecting precise and true-to-life hues. Factory settings fell short in this regard, but now colours appear realistic, as though accurately rendered according to the creators’ intent. This marks a substantial improvement over previous generations, where colours often appeared distorted or overly saturated.

Brightness also benefits from calibration, becoming sharper and more refined. The Gamma, already fairly consistent, is now even more stable, delivering a deeper and more natural image. Adjustments to the EOTF curve enhance detail visibility in darker areas and improve contrast balance. With these refinements, the television provides a nearly reference-quality image, greatly enriching the experience of movies and HDR content.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

Samsung S85D performs excellently in image scaling and smoothing tonal transitions. Like other Samsung models, the TV offers three noise reduction modes: off, standard, and high. While it improves gradation well, it unfortunately also removes film grain, which many viewers desire to give the image a cinematic character. Grain often adds authenticity and a certain rawness to films, which is lost after smoothing. Removing grain can make the image look too sterile and smoothed out, which takes away some of the charm of the original film material. As for image scaling, the Samsung S85D handles lower resolution content perfectly – the model in the photo and the branches in the background are shown correctly, without significant jagged edge issues. The only noticeable drawback is the presence of overscan, which can sometimes cut off parts of the image, which may not be to everyone's taste.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

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

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

The Samsung S85D is an excellent choice for gamers due to its many modern features that facilitate and enhance gameplay. The TV 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) function that automatically switches to low latency mode when it detects a gaming device. This way, you don't have to manually switch settings—the TV takes care of ensuring a quick response time, which is crucial in games where every second counts.

The VRR (Variable Refresh Rate) feature and G-Sync support are further elements that make gameplay smoother. VRR adjusts the refresh rate to match the frame rate generated by the console or PC, 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's worth appreciating. Thanks to it, the image in games becomes smoother—30 frames per second looks like 45, and 60 Hz gains fluidity, approximating a 90 Hz effect. Meanwhile, there is no significant increase in input lag, which remains below 25 ms, distinguishing this feature from others available on the market. Gamers can enjoy smoother visuals without worrying about a decline in responsiveness.

Samsung has also taken care of something extra—the TV has a built-in Xbox Game Pass app, which means you can play in the cloud without the need for 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 vast library of games at your fingertips. This makes the Samsung S85D a great choice for both casual gamers and more advanced ones.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.
