Philips OLED950 vs TCL P7L / P79L

The OLED950 is a phenomenal television for consuming content in HDR format, primarily thanks to the innovative Tandem OLED panel. With this technology, the screen can generate astronomical brightness levels, reaching over 2000 nits in film scenes (on test patterns). This is an exceptional result that places the OLED950 among the world’s top displays available on the market. However, it is important to note a specific characteristic of this solution – at moments when full-screen bursts of light appear on the screen, brightness can drop by as much as half. It is worth emphasising, though, that values above 1000 nits on a full screen are still an outstanding result. This allows for the HDR image to be displayed exactly as filmmakers would wish, maintaining the dynamics and impact of bright scenes.

The use of the Tandem OLED panel has also brought tangible benefits in terms of colour reproduction, improving elements that traditional WOLED panels struggled with compared to their QD-OLED competition. For the OLED950, the colour gamut coverage is broader than in classic WOLED panels, reaching nearly 100% of the DCI-P3 colour space and a solid 82% of the demanding BT.2020 palette. Although these results still do not match the high standards of QD-OLED panels, the difference diminishes during real-world use. We cannot deny that in the vast majority of films, colours look simply fantastic on this model – they are saturated, vibrant, and full of depth.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV does not have much luminance headroom, so strong highlights, the sun or small light sources can't clearly 'pop' out of the picture. As a result, even well-produced HDR material looks fairly restrained and, in terms of dynamics, is closer to good SDR than to what brighter models show. That does not mean the P7L completely fails at HDR. The issue is primarily a lack of backlight power.

Looking at colours, the situation is a little better. The TV covers around 91% of the DCI-P3 gamut and about 68% of the wide BT.2020 colour space, so for this price class the colour range is quite respectable. TCL markets this model as QLED, although the nature of the solution used is closer to backlighting that uses a PFS phosphor than to a classic quantum-dot layer. What matters most to the viewer, however, is the effect: more saturated colours are on offer.

We tested the OLED950 model in Film mode. Although it is theoretically the best and most faithful preset on this television, in practice it proved not to be free from flaws. Interestingly, in the unit we tested, the biggest challenge was not the white balance itself – although it did show a slight tendency to give the image a pinkish hue. The main issue lay in the way the television managed brightness, both in everyday SDR content and in demanding HDR scenes. The analysis of the gamma graph and the EOTF curve leads to one key conclusion: the television excessively exposes brightness in the lower registers. This results in the image appearing less contrasty than the panel technology allows. Details in dark areas that should remain perfectly black (characteristic of "OLED black") are simply unnecessarily highlighted and brightened. Fortunately, these errors can be corrected using the appropriate tools, which is why – as always – we proceeded with professional calibration.

In Film mode the TCL P7L performs quite respectably without major changes to the settings, particularly with ordinary SDR material. White balance is relatively even, though as brightness increases there is a slight rise in red and blue and a touch too little green. This does not, however, produce a strongly visible tint and most colours remain close to their reference points. The Colour Checker confirms this, with a large portion of errors falling below the level that should be particularly noticeable during normal viewing. We have more reservations about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference value, so some shadow detail can be a little too subdued. The characteristic then calms down and across much of the range it is close to the intended behaviour. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory calibration is less precise. As brightness increases the excess of blue becomes more pronounced, which can make the image look cooler than it should. The number of larger colour deviations also grows, particularly in brighter hues. As for the EOTF curve itself, it is handled fairly conservatively, with the TV showing the image darker than the reference across much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

As can be seen, the OLED950, after a professional calibration process, transforms into an absolutely phenomenal display that, without a shadow of a doubt, can be placed alongside the best televisions currently available in the world. This equipment only needed a professional touch to show its full potential and eliminate factory shortcomings. The minimal errors in reproduction in the Color Checker tests and the fidelity of the colour palette speak for themselves. We are dealing with an almost perfect device here. A true window to the world, offering image quality of the highest order.

After calibration the TCL P7L can deliver a genuinely pleasant picture, especially with conventional SDR material. We managed to even out the white balance very well, and the gamma curve now tracks close to the target value of 2.4. This is also reflected in the colour measurements: most errors have fallen noticeably, and in everyday viewing it is hard to point to any obvious inaccuracies. Films, series, YouTube and ordinary broadcast TV therefore look more natural, without unnecessary warmth or a cool tint. For a model in this price bracket the SDR performance is really very good.

With HDR the situation becomes more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and cannot maintain adequate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve the way the TV interprets the signal, but they cannot overcome its physical limits. That is why calibration makes most sense for this model primarily in SDR.

Upscaling

In terms of the image upscaling, the proprietary P5 processor performs just as well as in most models from this manufacturer. Low-resolution content takes on a very soft and plastic character. This kind of presentation will certainly appeal to many people. However, if you prefer sharper contours, you can lightly enhance them with the appropriate slider in the television's menu. It's really hard to find fault in this aspect. The image simply looks very good and additionally there is no issue with the phenomenon of overscan.

Smoothing and Distortion Reduction

The function for smoothing tonal transitions performs somewhat worse. In the settings, we find an option called "Distortion Reduction." This allows for three levels of adjustment of the processor's interference. Unfortunately, the Minimum setting works poorly and the smoothing effects are negligible. The Medium level gives a decent result, but it also starts to smooth out actors' skin details. On the other hand, the Maximum setting works too aggressively. It definitely removes too much detail from the faces and background elements, and can even take away the film grain. To achieve the optimal effect, it's worth experimenting with these settings at home and adjusting them to your preference. It may seem that the Medium option is the best compromise here.

In this respect the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The banding-reduction feature, which in many budget models does little or nothing, actually manages to improve the picture here. It does not remove all banding entirely, but it can noticeably reduce posterisation and make more challenging gradients look more natural. At this price point that’s a genuinely pleasant surprise. Upscaling itself also performs well. Lower-resolution material is scaled correctly, without over-sharpening or adding artificial outlines around objects. Of course the P7L won’t turn a very poor source into a 4K-quality image, but for regular TV the result is simply solid. For a model in this class there is little to criticise.

The motion reproduction in the OLED950 model is virtually perfect. This is typical for screens of this type (OLED 120Hz+), as the panel shows no blurring at all. This allows us to enjoy perfect sharpness in practically any conditions. Much of this is thanks not only to the specifics of organic technology. Equally important work is done by the smoothing systems implemented by the manufacturer.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be regarded in everyday use. When watching films the TV mainly offers frame interpolation, so it can smooth motion and reduce the characteristic judder, but it does not deliver the fluidity typical of true 120 Hz panels.

The OLED950 is nearly the perfect television for gamers. This is not only due to the unique atmosphere created by the Ambilight system during gameplay. The most important aspect here is the robust hardware support. You will find literally everything you should expect from a modern gaming display. The manufacturer has implemented two HDMI 2.1 ports with full bandwidth of 48 Gb/s. This gives us access to gaming in 4K resolution at 120 frames per second. Of course, support for VRR technology and the automatic ALLM game mode is also included. The device handles any HDR signal without difficulty, whether we are using Dolby Vision or the HGiG standard.

Access to all settings is available from one place thanks to the special Game Bar overlay. Although this interface may not be the most visually appealing on the market, it fully accomplishes its purpose. It displays all the important signal parameters and offers useful extras. Gamers can take advantage of the minimap zoom feature or add a permanent crosshair on the screen, which can be seen as a small aid in online competition. The contrast range adjustment also proves to be useful, as it allows you to brighten shadows and gain better visibility of enemies hidden in dark corners of the map.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL also includes its Game Bar, which lets you quickly check the key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn’t work here as it should, but at this price point it’s hard to complain about the feature set. The most interesting part starts when you give up 4K. At that resolution the TV runs at up to 60 Hz, but at 1440p and 1080p it can display at 120 Hz. And that’s not just a line in the specs. In fast-paced games that support that frame rate you can really notice the improvement in smoothness, so if you value smoother motion more than maximum image detail, that mode can make a lot of sense. Of course, that doesn’t turn the P7L into a proper 120 Hz TV. Even so, those extra modes are exactly what make the P7L perform very well for gaming.
