Compare: Philips OLED809/819 vs TCL C75B

Philips OLED 809 is a quite versatile television that appeals to a wide range of viewers. Its greatest distinguishing feature among all the television models on the market is the multicolour Ambilight backlighting. This often allows for an even greater immersion and engagement in the world of film. What is most important in televisions, namely contrast, black levels, and colour reproduction, is at a high level, and this is something that will always impress in OLED televisions. The tested television, although it performed quite well in our test, has some shortcomings worth noting. These include the quality of tonal transitions and the abrupt operation of the dynamic tone mapping function. In some cases, these may slightly irritate sensitive eyes. However, Philips OLED 809 excels in other respects, particularly in two areas: gaming performance and motion smoothing. The former stands out particularly strongly, as each of the implemented functions operates without the slightest hesitation, allowing for an even more immersive gaming experience. As for motion fluidity, it is at a similarly high level as the gaming support. Thanks to two sliders, whose effects are noticeable at each position, every user can find the best degree of smoothing for themselves. It’s also worth mentioning the Google TV system, which operates very smoothly and during the tests there were no "stutters".

The mid-range TV segment is expanding rapidly, and the TCL C75B demonstrates that you can get really solid equipment in this price range. This model has been clearly designed with gamers in mind – the HDMI 2.1 port offers ample scope, providing VRR, ALLM, as well as impressive 144 Hz refresh rates in 4K (or 240 Hz in Full HD), which will surely satisfy both gaming and sports fans. Operating the TV is enjoyable and intuitive, mainly thanks to the Google TV system. Although you may encounter slight stutters, the wealth of available applications and features compensates for that – practically everything we need is at our fingertips or even accessible by voice if we wish to converse with the remote in Polish. As for picture quality, the TCL C75B also performs well. Thanks to its VA panel, it boasts quite good contrast, and the presence of Dolby Vision allows for enjoyable HDR effects, even if the brightness isn't groundbreaking. Of course, it is not equipment without flaws – despite the fast panel, there is some motion blur, and the lack of traditional features (like USB recording) may disappoint some users. Nevertheless, in its price category, the C75B is a very attractive option, especially for those looking for a screen designed for high-level gaming.

Philips OLED 809, as the name suggests, uses an organic matrix. Like the vast majority of manufacturers, it comes from the LG Displays factory, which is not surprising, as other leading manufacturers like Sony and Panasonic also use them. The application of this type of panel allows for achieving an ideal result in the contrast and black testing procedure. Thanks to such results, the image is incredibly vivid and free of any blooming effect from bright text on a dark background, which is already an indispensable element of televisions with local dimming. This is made possible by the very construction of the panel, which is not made up of many layers of filters, but from conductive organic polymers, controlled by electrical impulses. Thus, if we want to achieve black, the pixel dims to a value of 0, rather than being obscured. The lights present in the test image are perfectly separated from each other, which is extremely difficult, and often impossible, for LCD televisions. One of the strongest advantages of Philips OLED 809 is its ability to render contrasts. The Philips OLED809 test showed that the television excels at separating bright elements, such as headlights, from dark backgrounds.

The TCL C75B television tested by us in size X" is equipped with a VA panel, which naturally provides quite decent contrast results – and this was also observed during our tests. On each test pattern, the television achieved a contrast ratio of around 5500:1. This is a result that can be considered very good in this price range. The black levels on this model perform really well, although of course, they are far from perfect.

Due to the C75B's belonging to the mid-range segment, we do not find local dimming technology here. This is particularly noticeable in more demanding scenes, such as those from the film Sicario 2, where we observed that the black takes on a navy shade instead of a deep black. This limitation of panels without local dimming can be especially visible in evening screenings with the lights off, when the dark elements of the image are more prominent. It is worth remembering this when choosing a television in this category, especially if we care about the best quality of black while watching films at night.

Philips OLED 809 delivers a more than satisfying HDR effect. The television is capable of generating brightness exceeding 900 nits in almost every scene, and sometimes even over 1000. This result allows for a full experience of content with a wide tonal range. The only moment when Philips OLED 809 is unable to generate higher brightness is in a scene from the movie “The Meg,” which features a large amount of bright white across a significant portion of the screen. However, this cannot be regarded as a poor result, as it represents a considerable improvement over its predecessor. Generally speaking, such values for OLED panels produced by LG Display, which do not feature MLA technology, are very, very good. When combined with high coverage of the DCI-P3 colour gamut, they allow for an exceptional HDR experience. The Philips OLED 809 test showed that this television supports popular HDR formats such as Dolby Vision and HDR10+.

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.

The best factory mode in which we conducted all our tests was "Filmmaker", which has become rather standard in televisions from this manufacturer. However, let's check what its characteristics were before we began the calibration process. The first aspect we will examine is white balance, as despite appearing unassuming, it determines whether the image will be free from any kind of tint. The graph clearly shows that both in SDR and HDR materials, there was a dominant presence of two colours: red and green, which resulted in a strong yellow tint that was ubiquitous across the entire image. This is perfectly visible on the "ColourChecker" palette, where all hues shifted towards their warmer counterparts. The second thing we will scrutinise is, in our opinion, the two most important graphs regarding image quality assessment: gamma and the EOTF curve. Both aim to maintain adequate brightness and contrast. The first one serves to describe the brightness level in SDR materials, while the second shows the rate of luminance increase. Analyzing the first one, we can observe that it was extremely lowered compared to the reference value marked by the orange line. This situation resulted primarily in a sharp increase in brightness and a significant reduction in contrast, almost reminiscent of that in OLED televisions. The EOTF curve exhibited greater "moderation" and only slightly brightened the entire image to 50% of the maximum brightness.

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.

Philips, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we will find both 2- and 20-point grey scale adjustments, as well as an advanced CMS (Colour Management System). As you can observe, this has brought about extremely beneficial results and profoundly changed the perceived image. Practically every one of the elements mentioned above has undergone a transformation and has been brought back to its natural state. This is particularly evident on the "ColourChecker" palette, where the measured samples are harmoniously in place. It must be said that the white balance has turned out exceptionally well, allowing us to enjoy a clean image free from any tint in both SDR and HDR materials. The biggest issue of OLED809, namely gamma, has been properly modelled and only shows minor errors here and there, which will not affect the overall picture. The EOTF curve, on the other hand, has been rid of that subtle brightening and now presents itself as reference-level.

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.

Equally important as colours, blackness and contrast in the context of the image quality assessment process is its purity. This category can also include the quality of tonal transitions. How many of you have experienced the effect of "banding" of colours on your older receivers? It is extremely bothersome and often effectively hinders immersion in the series or film being watched. Philips OLED 809 unfortunately has one of those qualities that are better left unspoken. However, out of editorial duty, we should take a look at them and evaluate, which will be quite simple given their lack of complexity. As you can see, practically every scene demonstrated a lack of fluidity between colours. And just as in the film "Kingsman" this is still acceptable, in other productions it is really impossible to leave them with a clean conscience, especially when looking at "The Green Knight." There, the dense fog has practically been converted into horizontal stripes and vaguely defined geometric shapes. There are televisions that can manage tonal transitions perfectly, but Philips OLED 809 unfortunately does not belong to this group. During the tests, we could observe the colour banding effect, particularly in demanding scenes, which negatively impacts the reception of the film. Philips OLED 809 test indicates that even options for removing posterization do not help sufficiently, which can be considered a serious flaw.

In terms of the smoothness of tonal transitions, the TCL C75B performs really well. The gradation of the darkest colours is particularly impressive – here the television does not disappoint and presents a high-quality image.

Some imperfections can be seen in the brightest areas of the screen, such as in a scene from the film Kingsman (the sun in the blue sky). Nevertheless, the final effect should satisfy the vast majority of users.

Philips OLED 809 did not perform particularly well in the test of tonal transition fluidity. Moving on to the part of the test where we assess the behaviour of the television's algorithms, we will once again check the function responsible for removing posterization. Indeed, such a function exists in the menu and has several available options. As you can see in the picture on the left, although its presence has been confirmed by us, it is not useful. Only at the highest setting does it effectively remove stuttering; however, it blurs the entire image in the process. Therefore, it is completely useless.

It happens more than once or twice that you and we watch lower quality materials. In this case, the quality of the image upscaling algorithms can have a beneficial effect. We must admit that those implemented in OLED 809 work quite efficiently and improve image quality without visible artifacts. You can only notice slight edge fringing; however, it is unlikely to be visible during normal viewing.

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 maximum refresh rate we can set on the tested television is 144 Hz. This value can be achieved by connecting it to a really powerful PC. In the case of consoles or television, everything remains the same. For those who require high smoothness of motion or dislike the characteristic stuttering of films recorded at 24 fps, the manufacturer has prepared a fairly extensive motion smoothing system. In the dedicated tab, we will find a slider for “Smoothness” that is responsible for eliminating stutter, and “Motion Blur Reduction,” which helps increase the sharpness of dynamic elements. The function works very well and granularly, meaning that each setting has a real impact on the perception of motion. We also mention that it works at a refresh rate of 120 Hz, as it operates on multiples of film or television materials. With such an extensive set of options, every user will find their golden mean. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

Motion is influenced not only by settings on the television but also by the response time of the panel itself. OLED televisions feature the best response time on the market, which in the case of 809 is about 0.1 ms. There are no IPS/ADS or especially VA panels that come close to the results of organic panels.

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.

The Philips OLED 809 television supports all technologies included in the HDMI 2.1 standard, and during our testing, each one activated without any problems. Therefore, we must state that this television is perfectly suited for all gamers, whether they are using a console or a computer. It is worth mentioning that the manufacturer has opted to implement the HGIG mode, which provides a great alternative to Dolby Vision, which unfortunately in the OLED809 is unplayable due to very high input lag.

A nod to gamers is also the inclusion of a dedicated GameBar, which allows for monitoring current gameplay parameters and quick changes to settings. We will also find a function to enable a crosshair, which will be very useful when shooting with a sniper rifle, but from the so-called hip. Additionally, we can also find a shadow enhancement function for better visibility in shadows and a colour filter for gamers with visual impairments.

In summary, the OLED 809 is a very good and versatile device for gamers. Anyone who purchases this television for gaming does not need to worry about anything, as it is simply made for gaming. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will allow for an even greater immersion in their favourite title. Lastly, we will add that the only downside of the television in game mode is the artificial image sharpening, regardless of the settings, and it cannot be 'softened'.

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.

The results of input lag measurements in the Philips OLED 809 are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which mean that a game running at 4K120Hz with HDR has only 5 ms of lag, which is practically unnoticeable even in online games. One should not forget the proper implementation of the gaming mode with Dolby Vision, which deserves praise for a similar reaction time of 13 ms. In this case, the Philips OLED 809 receives our highest rating.

Input lag in the TCL C75B is something that really impresses. At a refresh rate of 144 Hz, the lag is only 9 ms, which makes the TV's response to our actions on the pad or keyboard practically instantaneous. For 60 Hz, the result is 19 ms – while not record-breakingly low, it still falls within the range where delays are practically unnoticeable during gaming. One could say that the difference would not be felt anyway, which makes this TV a good choice even for more demanding gamers.

Just like in games, the tested television performs excellently, but in everyday work with text, it doesn't do so well. Although its latency is very low, the problem lies elsewhere. The television does not support chroma 4:4:4, which results in unpleasant font blurring, regardless of the provided refresh rate. While this is not usually a problem in games, it can be quite bothersome during text work due to poor readability. Additionally, the pixel arrangement in WOLED panels does not make things easier for it.

TCL C75B is quite a good choice for connecting to a computer. With high refresh rates, low input lag, and support for G-Sync, the television performs excellently in games – both dynamic ones and more demanding titles. The image is smooth, and the response to our actions is quick, which gamers will surely appreciate.

For office work, the television also does well. Text is readable, although on a dark background some imperfections can be noticed – certain fonts look as if there are missing pieces of vertical lines. This may be distracting if we work a lot with documents or text editing. However, if the computer is mainly used for gaming or watching films, the TCL C75B will easily fulfill its role as a monitor. It is a versatile piece of equipment that can handle most applications.

A widely known advantage of OLED matrices is their performance when viewed even at sharp angles. We do not experience a drop in contrast or colour saturation. However, a characteristic feature of panels produced by LG Display, which are not used in top models, is a tint in shades of sea or cyan when viewed at large angles.

The viewing angles on the TCL C75B are, unfortunately, very poor. This is a typical compromise with VA panels – better blacks at the cost of side viewing visibility. The image quickly loses quality when viewed from an angle, which is the complete opposite of what IPS panel televisions offer. If we plan to watch the television mainly straight on, this won't be a major issue. However, with a larger number of viewers sitting at different angles, the image quality may disappoint.

For many years, the issue raised regarding OLED televisions has been their performance during the day. Many people still believe that these are not receivers intended for such use. They are probably right, except when it comes to screens from a few good years back. Technology advances, and currently there are no objections to recommending such a television for today. Admittedly, a glossy panel does not sound like something that would substantiate this claim; however, it is hard to stand against the images that you can see for yourselves. Another point we indicate to pay attention to is contrast during daytime use. This, unlike QD-OLED panels, and even OLEDs equipped with MLA technology, is higher. The reason for this situation is the lack of excited quantum dots and micro-lenses.

The TCL C75B performs moderately during the day. The satin screen somewhat limits reflections, but it's not an ideal solution. The brightness is also an issue – 350 cd/m² is simply too low for comfortable viewing in a brightly lit room.

In less extreme conditions, such as in a moderately lit room, the television manages well. However, if the sun beams directly onto the screen in summer, watching may become tiring. It's worth keeping this in mind when choosing this model.

Before we move on to the software that controls the television, it is impossible not to mention the manufacturer's biggest differentiator. We are, of course, talking about the multicoloured Ambilight backlighting, which placed on the back of the device displays colours adjusted to what is happening on the screen, often allowing for an even greater immersion experience. The Philips OLED 809 is powered by the Google TV system. This is an undeniable advantage compared to some other models from the manufacturer that use the proprietary TitanOS system, which is significantly more closed and limited in terms of available applications. With Google TV, we can install almost any application, both from the store and directly from online repositories via an APK file.

The Google TV system also offers many conveniences related to control. We can easily connect a keyboard with a touchpad, which significantly facilitates typing queries and navigation. Additionally, thanks to integration with Google, we can issue voice commands using the remote, which are quickly and accurately interpreted by the system.

In summary: Google TV is currently one of the most popular systems on the market. Thanks to the use of a powerful CPU, it operates very smoothly and stably, without freezing or experiencing lags during tests. It is definitely the best option for those who want to make the most of their television's capabilities and appreciate the openness and versatility of the system.

TCL C75B is a television that is primarily based on the Google TV system. The platform offers access to most popular applications, such as Netflix, YouTube, and Prime Video, which makes it great for watching content from the internet. However, it should be mentioned that the system can sometimes be slightly laggy, which may be noticeable during everyday use.

In terms of smart features, the C75B performs well. Voice control with the help of the built-in assistant works efficiently, and thanks to AirPlay and Miracast, it is easy to stream content from your phone or laptop. Bluetooth allows you to connect headphones, controllers, or other devices without any major issues.

However, if someone is counting on traditional television features, they may be disappointed. There is no option to record programmes onto a USB drive, nor is there a picture-in-picture (PiP) feature. TCL has been omitting such features for some time, which may not appeal to users who primarily use traditional television.

The default media player in Philips OLED 809 is of a fairly high standard, although it is not without its flaws. It performs excellently in playing various types of video files, except for two less popular ones. The presence of all checkboxes confirming playback of different subtitle formats deserves a big plus. The television handles every resolution of images, making it an excellent screen for viewing family albums or studio photos. The rest, including supported photo and audio formats, is satisfactory, and those that the television cannot play are either uncommon or becoming obsolete. Anyway, this is not a problem, as we can download a program from the app store that will resolve these issues.

The built-in media player in the TCL C75B works really well. It handles most popular photo and audio formats without any issues. Although there are some shortcomings in supporting certain formats, thanks to Google TV, you can easily install an alternative player that will resolve this issue.

At the outset of this paragraph, it should be noted that sound quality is always subjective. In our opinion, the audio system that the manufacturer has equipped the Philips OLED 809 with is of a fairly high standard. The bass is well-defined, but at the same time, it does not overshadow the mid and high tones. Looking at it from another angle, when opting for a television at this price point, we will likely already have a separate audio system. In this context, the tested television will certainly not disappoint, as it supports virtually every important standard, including Dolby Atmos and, more importantly, DTS-HD Master Audio.

The sound on the TCL C75B is really pleasant, especially at lower volume levels. The bass is noticeable and enhances the sound nicely, but only up to about 40% volume. At higher settings, problems start to arise – the bass causes unpleasant vibrations, and the speakers begin to crackle. If we plan to frequently use higher volume levels, it is worth considering purchasing a soundbar, as the built-in speakers may not cope with more demanding situations.
