LG OLED C6H (TANDEM OLED) vs Philips PQS9011 / PQS9001 (The One 2026)

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.

The Philips PQS9000 is a moderately bright TV — in our HDR scenes it reached roughly 450 to just over 500 nits. That’s enough to notice a difference compared with SDR. Sun reflections, lamps or flares have a bit more punch than on basic TVs, whose brightness often tops out around 300 nits. It’s not, however, a level where bright elements look especially striking. The biggest limitation remains contrast. Without local dimming, brightening a bright object also lifts the black level around it. So there’s no clear separation between strong highlights and a dark background, and it’s that kind of pairing that really shows what HDR can do. The PQS9000 offers more than the cheapest models, but despite decent brightness the effect remains fairly basic.

Colours

Philips deserves praise for the colours. Although the manufacturer markets this model as QLED, it actually uses a PFS phosphor instead of quantum dots. The solution itself doesn’t prevent good results. On test patterns and in measurements of film scenes we recorded about 94% DCI-P3 coverage and 75% BT.2020. For this class of TV that’s really good. In practice this means the vast majority of colours used in HDR films and series will have appropriate saturation. Lush greens or intense reds aren’t a problem and add appeal to the picture. Limitations are easier to notice in some games and rarer content that use the most saturated shades of the wide BT.2020 gamut. In those situations, displays with wider colour coverage, such as SQD or RGB LED, can show more. At its price point the PQS9000 has nothing to be ashamed of.

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.

The factory picture settings for Movie mode on the PQS9000 unfortunately need tweaking. In SDR the biggest problem is an excess of red in the white balance, which makes whites, greys and skin tones too warm, in places even slightly pink. Gamma runs below the reference across most of the range. The TV therefore brightens midtones and highlights, making the image look flatter than it should.

In HDR the white balance itself performs significantly better. Apart from minor deviations the components sit close together, so there isn’t the same obvious tint as in SDR. The EOTF curve, however, shows a slight brightening of parts of the image, and the biggest issue appears when measuring the wide colour gamut. Many shades deviate substantially from the target, with errors reaching ΔE 8–9. The good gamut coverage we praised earlier therefore doesn’t mean the TV hits specific colours accurately. It can display a wide range of colours, but out of the box it doesn’t use that range very precisely.

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.

Calibration brought a big improvement, especially with SDR content. We managed to even out the white balance and remove the earlier colour cast, and the Color Checker measurements now look very good. Colours are much closer to what they should be on screen, so with regular TV or SDR movies we can be happy with the result. Unfortunately HDR spoils that a bit. On the one hand it's limited by the panel itself, because calibration won't improve contrast or replace local dimming. On the other hand there are colour errors we couldn't correct because the CMS settings, i.e. colour management, were greyed out and inactive. That loses Philips points with us. The white balance can be fine-tuned, but without access to wide gamut controls you can't as effectively sort out colours in HDR. It's a shame, because the SDR results show the potential is there, but we weren't allowed to fully make use of it everywhere.

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.

Digital image processing on the Philips PQS9000 performs well, although we have a few reservations. The "Distortion Reduction" function helps smooth tonal transitions in lower-quality sources, but it works rather unevenly. It can improve one part of the picture, only to, moments later and still within the same scene, lose its way and show banding between shades again. On the plus side, it doesn't strip away film grain or fine noise, so the image retains its texture. We found the "Medium" setting worked best and that's the one we recommend.

The upscaling to 4K itself is adequate, though the image is very soft. Edges are heavily smoothed, which may leave some viewers wanting more clarity. In that case, it's worth slightly increasing the sharpness in the TV menu, as this will help emphasise edges more. Don't overdo the sharpness slider, though, or you'll get artificial halos instead of an improvement.

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.

In terms of motion handling the Philips PQS9000 performs exceptionally well for an LCD TV. It's not just about the 144 Hz refresh rate, but above all how quickly the panel itself responds. At 120 Hz you can hardly see the typical trailing smears behind moving objects. What's particularly pleasing is that this also applies to darker backgrounds, where many VA panels clearly struggle. Here motion remains clear, and in this respect Philips has pleasantly surprised us.

The "Motion Styles" feature is used to adjust how motion is displayed. It includes two sliders: "Smoothness" and "Blur Reduction", allowing you to tailor the effect to the material you're watching and your personal preferences. Our suggested settings are shown in the photo. Treat them as a starting point and see which level of smoothing suits you best.

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.

Features for gamers

In terms of gaming features the Philips PQS9000 has a lot to offer. Four HDMI 2.1 ports let you connect multiple devices without having to choose which one gets the full capabilities. Consoles can use 120 Hz at Full HD, 1440p and 4K, and a PC can also run 144 Hz at 4K or 240 Hz if you drop to Full HD. There's also VRR, which matches the refresh rate to the frame rate and prevents screen tearing. Its range runs from 48 to 240 Hz, with the upper limit applying to Full HD mode.

It also includes ALLM, so the TV switches itself into game mode, and a properly working HGiG, which is handy when setting HDR on the console. There's a Game Bar for quick access to settings and signal information. The list even includes Dolby Vision gaming, but it's hard to enjoy because of very high input lag. Apart from that caveat, the feature set is really solid.
