TCL C69K / Q6C vs Samsung S85H

In terms of brightness, TCL C69K / Q6C is a moderate model. In optimal movie conditions, it shows its full potential, reaching a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, giving a cinematic glow. However, it's important to keep in mind that when managing the backlight zones, there are situations where parts of the image are dimmed, and at times become barely visible. This suggests that there is still a lack of proper optimization of the algorithms, although considering the technical parameters in this price range, the overall construction still looks very good.

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 lineup. In the same film scenes last year’s model sat closer to about 700 nits, while the S85H can reach roughly 800 nits. That’s not a change that completely transforms the HDR experience, but the extra headroom is noticeable, especially with point highlights, reflections or stronger special effects. Around 800 nits is a very good result for an entry-level OLED and in most films it’s enough for HDR to have the necessary punch. Bright elements can clearly stand out against perfect blacks, and that contrast is still doing most of the work here. However, you need to remember the typical limitation of OLED technology. When a very bright scene covers a large portion of the screen, brightness can drop to almost half. This is the result of panel protections that limit its output with large bright areas.

Colours

The S85H can deliver very pleasant, saturated colours and in most HDR films it looks really good in that regard. We measured around 95% coverage of DCI-P3, so the palette most commonly used in films is reproduced to a very high degree. Skin tones, greens and stronger reds still have appropriate intensity and under normal viewing it’s hard to have major complaints. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was about 70%, a bit less than WOLEDs of the previous generation and noticeably less than QD-OLED panels. In films this isn’t a big loss, since most productions rarely use such heavily saturated colours. You’re more likely to notice it in games, where developers more often opt for more intense colours.

The Filmmaker Mode, which has been introduced in this year's TCL TVs (including the C69K / Q6C), is definitely the best choice "to start with". This is the mode we recommend for everyday movie and series viewing. Unfortunately, as is often the case, best does not mean perfect. In SDR materials, the image turned out to be too warm, with a strong red tint in the white balance. The opposite impression was had with HDR content – here the image became cooler than it should have been, due to an excess of blue. Additionally, there is the brightness characteristic, which at times resulted in overexposures. In practice, this translated to fairly noticeable errors in color tests, which is difficult to accept in a mode branded as "by the creators".

To evaluate colours we of course used Filmmaker mode, and in SDR our S85H unit was set very well from the factory. The largest deviation appears in the white balance, where as brightness increases it starts to lose a bit of blue. In practice this means whites and greys have a slightly warmer tint than they should. However, it's not a big fault and during normal viewing it generally isn't very noticeable. Gamma also stays close to the reference value, so the picture is neither overly bright nor unnecessarily dim. The S85H's SDR picture therefore looks really good straight out of the box. A few more imperfections appear in HDR. Here the white balance shifts more with rising brightness, with blue starting to dominate and the red component clearly lacking. This also results in larger errors in some colours. These aren't yet colour errors that completely change the character of the picture, but in direct comparison with the reference the difference is easier to spot. Overall, Filmmaker mode is a very good starting point before professional calibration.

Through white balance adjustment, we were able to significantly reduce the tendency of ChooseTV C69K / Q6C to distort colours, which resulted in a very good final outcome. After calibration, the problem of excessive warming of scenes in SDR and over-cooling of the image in HDR disappeared. However, it's worth analysing the brightness characteristics more closely. While in SDR content there are few complaints – the picture looks really good, especially in older films, TV programmes, or on YouTube – it performs much worse with HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the actual construction become evident. This model tends to excessively brighten small parts of the frame, while in other situations, it darkens the entire scene too much. The effect of calibration is therefore undeniable, and in terms of colourimetry, ChooseTV C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

Calibration delivers really good results on the S85H. First and foremost, we were able to set the white balance almost perfectly, which removes the slightly too-warm picture tone previously seen in SDR. Colour reproduction also improves significantly, with most errors falling to very low levels, and in everyday viewing it's hard to find any visible inaccuracies. You can also improve HDR quite a bit, although some issues remain that stem from the TV's inherent characteristics. The S85H doesn't always hold the luminance curve perfectly. The darkest parts are slightly boosted, while, as you approach the panel's limits, you can see small deviations in the brightest highlights. Add to that the limited coverage of the wider BT.2020 colour gamut, which of course cannot be overcome by any calibration. Despite that, the end result is very good, and after calibration the S85H can deliver a really well-tuned, natural image.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content is presented acceptably, and due to the lack of overscan issues, the image is displayed in full without any cropping. However, don’t expect miracles – materials of very low quality won’t gain a second life here, as the image processor has its limitations.

On thin lines and details, there is noticeable jaggedness, which reveals the lack of more advanced image enhancement algorithms. It's also a shame that the C69K / Q6C lacks a feature for smoothing tonal transitions. As a result, in older films or video materials, color banding can be visible and may become distracting during extended viewing.

Samsung's S85H uses the same proprietary AI processor, AI NQ4 Gen2, as last year’s S85F, and in terms of digital image processing it performs quite well. Upscaling is one of the model's stronger points. Lower-resolution material is well sharpened, edges look natural and the picture doesn't come across as overly artificial. Just remember a common quirk of Samsung TVs: at very low resolutions you can't completely turn off overscan, so the TV may slightly crop the left edge of the picture. The "noise reduction" function, that is smoothing weaker tonal transitions, also works very well. The processor can effectively remove posterisation and other artefacts visible in lower-quality material. However, be careful with the strength of this function, because Samsung can be fairly aggressive here. When it's activated, along with unwanted artefacts, fine details such as skin or clothing texture also start to disappear.

The use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. This represents an important step forward compared to its predecessor (C655 PRO), which only offered 60 Hz at 4K. The difference is particularly noticeable when watching sports or gaming – the ball, players, and dynamic action in games are displayed more clearly and without losing detail. An interesting feature is also the panel's ability to operate at 240 Hz (which the manufacturer does not officially mention) – we will revisit this topic in relation to the PC gaming mode. TCL has also added a feature for movie fans: “Motion Clarity.” This allows users to adjust the picture to their own preferences using two simple sliders. We can either leave the visible film frame or opt for a very smooth one, "

The S85H uses an OLED panel, so it performs brilliantly when it comes to motion blur. Pixels respond almost instantly, so moving objects don't produce the characteristic ghosting seen on some LCD TVs. This is especially noticeable with sport or fast-paced games, where the picture stays very clean even during rapid motion. The panel itself runs at 120 Hz. That's more than enough for movies, TV shows, sport or console gaming. It's a shame Samsung didn't include a higher refresh rate aimed at PC gamers, as more and more TVs now offer 144 or even 165 Hz at 4K. However, that doesn't affect motion handling in films or sport.

There's also the classic motion smoothing feature with two settings: blur reduction and judder reduction. So you can choose whether films should keep their cinematic 24 frames per second, or whether you'd prefer to smooth them a bit. The S85H gives plenty of freedom here, and the interpolation itself works well and, with sensible settings, doesn't generate too many artefacts.

TCL C69K / Q6C is a television that can confidently be called equipment designed for gamers. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, which is a panel with the most important settings within easy reach – handy when we want to change something quickly during gameplay (e.g., aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is noteworthy. However, this option is mainly for PC gamers looking to go below native 4K resolution. In this case, the television can spread its wings and show additional smoothness, particularly in fast e-sport titles. For consoles, we stick to the standard limit of 120 Hz, but even so, the possibilities are truly extensive. The only minor criticism is slight ghosting that can sometimes be seen in dynamic scenes. Other than that, C69K / Q6C offers everything gamers expect from a television.

Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a computer. The manufacturer didn’t skimp on connectors and all four HDMI ports support full HDMI 2.1. That means you can use 4K at 120 Hz, VRR and ALLM without worrying which input to plug your console into. With multiple devices that matters a lot, since you don’t have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very complete. The S85H supports VRR, FreeSync and automatic switching to Game Mode, and Samsung also offers its expanded Game Bar, which lets you quickly view the key signal parameters and change settings without leaving the game. The only real omission is Dolby Vision, which will matter mainly for Xbox owners. That’s a typical trait of Samsung TVs. Game Motion Plus performs very well and it’s one of the features that has set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as large an increase in input lag as a classic motion interpolator. In practice, for slower-paced games, racing or action titles it can genuinely improve motion perception, especially if you’re sensitive to low frame rates.
