PHILIPS PUS9010 (IPS) vs LG OLED C6H (TANDEM OLED)

In the Philips PUS9010 version with an IPS panel, the HDR brightness sadly performs worse than in the previously tested 55-inch variant with a VA panel. The difference reaches about 100 nits, which is noticeably significant given the relatively low values. While the VA version could exceed 500 nits, here the maximum brightness reaches around 400 nits. This level still allows for watching movies and series in HDR, especially on streaming platforms, but the effects are clearly more subdued. Bright elements don't have the same impact, and scenes requiring high luminance are less impressive. On the plus side, the coverage of the DCI-P3 colour gamut is commendable. The IPS version offers about 91%, which is roughly 5% more than the variant with a VA panel. This translates into slightly better colour saturation in HDR content, despite the lower brightness. Colours can appear more vivid and cohesive, especially in colourful scenes.

And the biggest advantage of the Tandem OLED panel is most obvious with HDR. The C6H's brightness is simply very high and, in our measurements across most film scenes, hovered around 1,900 to 2,300 nits. That's the kind of level at which bright highlights, the sun or small light sources can look truly spectacular. The scene that impressed us most was the fifth scene from the film The Meg. It's particularly demanding for OLEDs because almost the entire screen is extremely bright. Even so, the C6H reached about 1,650 nits in that scene. By comparison, the standard C6 with a classic WOLED panel managed roughly 600 to 700 nits at the same point. So we're talking about more than double the brightness, and in places the difference approaches three times as much. And that's probably the best example of what Tandem OLED delivers. It's not just a higher score on a small test window. The C6H can maintain very high brightness even when much more of the screen is illuminated. That gives HDR a much wider dynamic range, and in this respect the C6H is considerably closer to flagship OLEDs than to typical mid-range models.

Colours

Tandem OLED also brings improvements in colour. DCI-P3 coverage remains virtually complete at around 99%, while in the much wider BT.2020 colour space we measured about 82–83%. That's roughly 7 percentage points more than the standard C6. In everyday viewing this won't be a difference you notice in every scene, because most films don't use such a wide palette. However, when very highly saturated colours appear, the C6H has noticeably greater capability, especially with reds. Reds benefit the most, becoming deeper and more saturated. It's still not at the level of the best QD-OLED panels or SQD TVs, but for a WOLED panel the result is really very good.

We evaluated colour reproduction, as always, on factory settings, focusing on the movie mode, which in the case of Philips usually offers the best starting point. This is also a good moment to show how much the same model of TV can vary depending on the panel used. Looking at the white balance, the overall tendency remains similar to the version with the VA panel. There is still excessive red in the whites, however, in the tested unit with the IPS panel, there are also losses in the blue channel. As a result, the picture has a slightly different colour character, which is well illustrated in the comparative materials. This is a very good example showing why ready-made settings downloaded from the internet do not always work even within the same model.

However, returning to the assessment itself, this unit performs quite well, especially in SDR content. Colour tests show correct saturation and colour consistency, without glaring errors that could hinder everyday viewing. In HDR materials, it is possible to notice slight losses in reds, but these are not flaws that completely spoil the image perception. The biggest limitations do not stem directly from the colours, but rather from the whites and blacks. The use of an IPS panel and slightly lowered gamma means that the image is slightly boosted in brightness, and weak blacks further affect perceived contrast. This makes everything look brighter, but at the same time, it lacks depth, especially during evening viewing.

Right out of the box the LG C6 is pretty well set up, especially if you select Filmmaker mode. In SDR content the white balance is good, although as brightness increases it starts to lack red slightly. This makes the picture a bit cooler, but not enough to be very noticeable during normal viewing. More is going on in the luminance response. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 across a large part of the range. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses a little depth compared with how it should look in a dark room.

In HDR the situation is a bit more interesting. The start of the grayscale looks very good, but from around 20–30% brightness the white balance starts to drift more strongly. As brightness increases red builds up and blue becomes noticeably lacking. In the brightest parts the difference is already significant and also affects the reproduction of some colours. The EOTF curve itself is handled quite well across most of the range. The C6 only has a tendency to slightly brighten the picture, which we've already seen in our film comparisons. The biggest deviation appears around the brightest sections where the TV starts to adapt the signal to the panel's capabilities.

So the factory Filmmaker setting in HDR is not perfect, but overall performs well. The biggest room for improvement is the white balance, especially at high brightness.

After calibration, the picture has been brought to a really reasonable level. The whole thing looks cohesive and natural, and when it comes to colour reproduction, it's hard to definitively say whether we're dealing with a VA or IPS panel. This is a good sign, showing that the television has a solid foundation for further adjustments. The larger colour gamut in this variant is a plus, as it can subtly enhance the depiction of colourful scenes, especially in HDR content. However, this advantage is largely offset by the boosted blacks resulting from the use of an IPS panel. The limited depth of black affects perceived contrast, particularly when watching in a dark room. As a result, despite noticeable improvement post-calibration, the final rating remains the same as that of the variant with a VA panel. Better colours are not able to fully compensate for the weaker blacks.

LG TVs have long responded very well to calibration, and the C6 is no exception. After adjustment, the white balance was set almost perfectly, and most colour errors fell to values below 3, often around 2. In practice this means very accurate colour reproduction in both SDR and HDR. An interesting detail only showed up with the HDR luminance response. On a classic EOTF chart everything looks almost perfect and at first glance it would be hard to fault. Only when we measured the TV’s behaviour using filters based on real film scenes did it emerge that the C6 has a slight tendency to artificially boost image brightness.

It isn’t a huge difference and many people may even see it as a positive, since HDR looks a bit more punchy. From the point of view of fidelity to the source material it’s not ideal, though — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is quite atypical for LG. In previous generations, this brand’s TVs usually stuck very closely to the reference picture characteristics after calibration. With the C6 we’re still very close to the standard, but that subtle boost in brightness can indeed be noticed in movies and TV shows.

In the Philips PUS9010, we find another iteration of the P5 Perfect Picture image processor, which aims to improve the quality of lower-grade materials. One of the components of this system is a distortion reduction function that smooths tonal transitions. It works effectively and actually reduces visible banding. Unfortunately, it does so quite aggressively. In practice, it can mute details such as material textures or film grain. This is a clear compromise, so we wouldn't particularly recommend it for movie sessions. For more casual content, like YouTube or regular television, it performs much better. The P5 processor also handles lower resolution materials quite well. The image is soft, at times even too soft, but it can easily be corrected using the sharpness slider, adjusting the effect to personal preferences. A positive aspect is also the absence of edge cropping in SD materials, which is still not standard in this class of televisions.

Here the LG C6 has taken a really big step forward. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very similar. That's a big plus, because in this area LG's processor this year performs excellently. The 'Smooth Gradation' function works especially well. With heavily compressed material it can effectively hide unsightly tonal banding and artefacts that often appear, for example, in lower-quality streaming. It's best left on the 'Low' setting. That way the improvement is clear, and the TV doesn't yet start to blur fine details. Higher levels smooth the picture more, but can begin to remove some of the natural texture of objects on screen. Upscaling itself also performs very well. Lower-resolution content is properly sharpened, edges look clean, and the processor quite effectively reconstructs fine details. In this respect the C6 is already really close to LG's top TVs and the differences compared with the G6 are small.

Philips PUS9010 has a 4K panel with a refresh rate of 144 Hz, which will be appreciated mainly by sports fans and gamers. This is especially noticeable in dynamic scenes where the motion is sharp, and annoying blur is almost non-existent. When it comes to movies (standard 24 fps), Philips offers us a proven set of settings known from its higher series. Two sliders are used to control motion. “Smoothness” allows you to adjust the picture to your liking: at low settings, it maintains a cinematic character, while moving the slider to the right gives us a perfectly smooth, albeit slightly “theatrical” effect. Meanwhile, “Motion Blur Reduction” is a feature designed for sports – it ensures that fast-moving objects do not lose detail and remain clear.

The C6H with a Tandem OLED panel can also run at a refresh rate of up to 165 Hz. PC gamers will get the most out of that, of course, because with consoles, films or sport we're still looking at a maximum of 120 Hz. The panel itself performs excellently in motion. OLED pixels respond almost instantly, so even with fast-moving objects you don't see the usual trailing. The picture stays clean both when watching sport and in fast-paced games.

If you prioritise smoothness over motion clarity, TruMotion is available. LG lets you adjust two parameters separately. De-Judder mainly works with films and series shot at 24 fps and reduces their characteristic judder. De-Blur is intended for 50/60 fps content, so it's mainly useful when watching sport or TV.

Philips PUS9010 is a solid machine for gaming. It has everything that’s important: VRR, automatic game mode (ALLM), and support for HGiG. The latter is fantastic – it allows you to set HDR in games exactly the way the developers envisioned. The TV handles 120 Hz refresh rates effortlessly at every popular resolution (1080p, 1440p, and 4K). It doesn’t matter if you connect a PS5, Xbox, or a powerful PC – everything runs smoothly and just as it should. Gamers will also appreciate the Game Bar. It’s a quick, clear menu where you can immediately see if the low latency mode is active. This is especially useful when frequently switching between different consoles. The whole experience is enhanced by Ambilight. Evening sessions with this backlighting create a whole different level of atmosphere; the image seems larger, and dynamic scenes are even more impressive. Even if someone isn’t a fan of such “gimmicks,” it’s hard to deny that it makes an impression.

The C6H offers virtually a full gaming feature set. On consoles you can easily use 4K at 120 Hz, while PC users can push the refresh rate up to 165 Hz. The TV also supports VRR from 40 to 165 Hz, ALLM and a correct implementation of HGiG. Dolby Vision is available in game mode too, which remains a big plus for Xbox owners. All the key info can be seen in the Game Bar, which provides quick access to VRR settings and the current signal parameters. The tandem OLED doesn’t change the actual feature set for gamers, but with such high panel brightness HDR games can look even more impressive. Functionally, the C6H is simply a very complete TV for consoles and PC.
