TCL C75B vs Philips PUS7000

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

Unfortunately, the PUS7000 is not suitable for watching HDR content. The screen is simply too dark. A brightness level of 200 nits is insufficient to properly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a standard SDR recording. Therefore, it is better to stick with the latter format to avoid errors in displaying bright scenes, as discussed below. The situation is not improved by the fact that this is a classic LCD model without additional layers enhancing colours, such as QLED or PFS. As a result, colours in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

We tested the television in movie mode, which theoretically should provide the best and most natural colours. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw came to light. The PUS7000 has significant shortcomings in displaying red. Poorly tuned white balance and overly low saturation of this colour cause the image to appear too cool. As a result, one may get the impression that the displayed content is simply lacking in vibrant colours. The situation is worsened by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and may appear somewhat washed out. Fortunately, in the Philips menu, we find quite a few functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

After calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

After professional calibration, it is evident that the PUS7000 responds well to image adjustments. In this price range, this is not at all a given. The effects should be evaluated in two scenarios, depending on what content we plan to watch. SDR performs the best. After our adjustments, the picture looks really good. Most colour errors have fallen below level 3, which is the threshold at which distortions usually begin to be visible to the naked eye in measurements. Films, series, sports, and regular television look natural, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable immediately. However, it must be clearly stated that the PUS7000 is still not a television suited for reasonable HDR, and calibration changes very little in this regard. The reason lies in the hardware: the colours remain too unsaturated. The television lacks solutions to expand the colour gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot display the intense colours required by HDR. This is most apparent in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it stems from the design of the backlighting and the panel itself.

TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at low settings. However, it has a drawback: if applied too aggressively, it can introduce undesirable artifacts on the screen. Therefore, it would be a good idea to experiment with this setting to find a happy medium between a smooth image and detail clarity.

The upscaling, or enhancing the quality of lower-resolution materials to 4K, is adequate. The image after processing is very "soft," which is typical for nearly all Philips televisions. The edges are plastic and smooth, making the image look cohesive. If it feels too soft for someone, the sharpness slider in the menu can always be adjusted to achieve a more pronounced effect.

The TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

In this respect, we actually have no good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that is actually the norm, and it is hard to expect anything more. However, the worst part is that the television does not have any features to improve motion smoothness. There is a lack of any supporting systems, both in films and in sports. We must come to terms with the fact that the image on the PUS7000 is processed "raw". This means that during dynamic scenes or fast camera movements, the motion can appear choppy or unclear. We do not have the option to enable any smoothers that would reduce this effect.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.

Although the PUS7000 is not marketed as a gaming television, it does not perform as poorly in this category as one might expect. While it is true that we won’t find support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has ensured several important features that genuinely enhance the gaming experience on consoles. The most important of these are the VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This prevents the image from tearing and keeps it consistent even during sudden drops in frame rate while gaming. In contrast, ALLM is a solution that automatically switches the television to the lowest latency mode as soon as it detects a signal from the console. All these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be summoned on screen at any time. It allows for a quick preview of the current settings and connection status without interrupting gameplay, which is a very convenient solution.
