TCL C75B vs Philips PUS7000

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 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. This screen is simply too dark. A brightness level of 200 nits is insufficient to display this format correctly. Even if a HDR signal message appears on the screen, the image will resemble a standard SDR recording. Therefore, it’s better to stick with the latter format to avoid errors in displaying bright scenes, as you will read below. The situation is worsened by the fact that this is a classic LCD model without additional layers that improve colours, such as QLED or PFS. As a result, colours in HDR may seem washed out. Ultimately, this provides a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

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

An additional problem was the way brightness was reproduced. 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 black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described 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, when we connected the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant shortcomings in displaying reds. Poorly tuned white balance and too low saturation of this colour cause the image to appear too cool. As a result, one might get the impression that the displayed content lacks 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 can make them seem slightly washed out. Fortunately, in the Philips menu, we find plenty of features to improve these aspects, so we immediately proceeded to calibration to see what we could extract from this screen.

After calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

After professional calibration, it’s evident that the PUS7000 responds well to image adjustments. In this price range, that’s not a given. The effects are best evaluated in two scenarios, depending on the content we plan to watch. SDR performs the best. After our adjustments, the image looks really good. Most colour errors have dropped below level 3, which is the threshold at which discrepancies usually become visible to the naked eye. Movies, series, sports, and regular television present naturally, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable straight away. However, it must be said clearly that the PUS7000 is still not a television suited for proper HDR, and calibration doesn't change much in this regard. The reason lies in the hardware: colours remain too unsaturated. The television lacks solutions that widen 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 evident in reds, which still look washed out. This limitation cannot be circumvented through menu settings, as it stems from the design of the backlighting and the panel itself.

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

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs 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 unwanted tonal transitions even at a low setting. However, it has its downside: with too aggressive operation, it can introduce undesirable artifacts on the screen. It would be a good idea to experiment with this setting to find the golden mean between a smooth image and the clarity of details.

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

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 budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

In this regard, 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's actually the norm, and it's hard to expect more. However, the worst part is that the television has no motion smoothing features. There are no supporting systems in place for either movies or sports. We have to 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, motion can appear choppy or unclear. We have no option to enable any smoothers that could alleviate this effect.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.

Even though the PUS7000 isn’t marketed as a gaming TV, it doesn't perform as poorly in this category as one might expect. True, it doesn't support 120 Hz refresh rates, which is understandable at this price point, but the manufacturer has included several important features that significantly improve the console gaming experience. The most important of these are VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This means the image doesn't "tear" and remains consistent even during sudden drops in frame rates while playing. On the other hand, ALLM is a solution that automatically switches the TV to a mode with the lowest latency immediately after detecting 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 brought up on the screen at any time. It allows for a quick view of current settings and connection status without interrupting gameplay, which is a very convenient solution.
