Philips PUS7000 vs LG OLED C6 (WOLED)

Unfortunately, the PUS7000 is not suitable for watching HDR content. The screen is simply too dark. A brightness level of 200 nits is insufficient to properly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a standard SDR recording. Therefore, it is better to stick with the latter format to avoid errors in displaying bright scenes, as discussed below. The situation is not improved by the fact that this is a classic LCD model without additional layers enhancing colours, such as QLED or PFS. As a result, colours in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

The HDR performance of the LG C6 is really very good. LG Display's new WOLED panel has primarily brought a considerable increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can deliver similar values in many typical film scenes. That gives the HDR the necessary impact. Bright highlights, lamps and sunlight can be really intense, and most HDR films simply look very impressive. Of course it's still an OLED, so brightness falls in scenes with a lot of white. This is well illustrated by the fifth scene in the film The Meg, where the C6 reached around 600 to 700 nits. That's still a very good result, but it also shows that the new panel hasn't shed all the limitations typical of OLEDs.

Colours

When it comes to colours, there is also little to complain about. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice the colours are very saturated and, importantly, stable across different scenes. This is worth emphasising, because not every TV behaves the same in this respect. In some RGB Mini LED models colour saturation can depend more strongly on image brightness. A wider colour palette is nowadays offered mainly by QD-OLED TVs and new SQD models with a new generation of quantum dots. However, the C6 still performs very strongly here and is able to produce suitably saturated colours in most film scenes.

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, after connecting the calibration equipment, its biggest flaw came to light. The PUS7000 has significant shortcomings in displaying red. Poorly tuned white balance and overly low saturation of this colour cause the image to appear too cool. As a result, one may get the impression that the displayed content is simply lacking in 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 may appear somewhat washed out. Fortunately, in the Philips menu, we find quite a few functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

Right out of the box the LG C6 is pretty well set up, especially if you choose Filmmaker mode. In SDR material the white balance is decent, although as brightness increases it starts to lack a bit of red. The picture becomes a little cooler as a result, but it’s not such a big difference that it stands out during normal viewing. More happens in the brightness response itself. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 over much of the range. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses some 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 about 20–30% brightness the white balance starts to drift more and more. As brightness rises there’s more red and a noticeable lack of blue. In the brightest highlights the difference is already significant and also affects reproduction of some colors. The EOTF curve itself is handled fairly well over most of the range. The C6 only has a tendency to slightly brighten the image, which we also saw during our film comparisons. The largest deviation appears around the brightest highlights, where the TV begins to adapt the signal to the panel’s capabilities. So the out-of-the-box Filmmaker mode in HDR isn’t perfect, but overall it performs well. The biggest room for improvement is the white balance, especially at high brightness.

After professional calibration, it is evident that the PUS7000 responds well to image adjustments. In this price range, this is not at all a given. The effects should be evaluated in two scenarios, depending on what content we plan to watch. SDR performs the best. After our adjustments, the picture looks really good. Most colour errors have fallen below level 3, which is the threshold at which distortions usually begin to be visible to the naked eye in measurements. Films, series, sports, and regular television look natural, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable immediately. However, it must be clearly stated that the PUS7000 is still not a television suited for reasonable HDR, and calibration changes very little in this regard. The reason lies in the hardware: the colours remain too unsaturated. The television lacks solutions to expand 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 apparent in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it stems from the design of the backlighting and the panel itself.

LG TVs have been very receptive to calibration for years and the C6 is no exception. After adjustment the white balance was set almost perfectly, and most colour errors dropped to values below 3, often even around 2. In practice this means very accurate colour reproduction, both in SDR and HDR. An interesting quirk only appeared with the luminance response in HDR. On a standard EOTF chart everything looks almost ideal and at first glance it would be hard to criticise. Only when we measured the TV's behaviour with filters based on actual film scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.

This is not a huge difference and many people may even view it positively, because HDR consequently looks a little more striking. From the perspective of fidelity to the source material this is not ideal, however, as some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is rather unusual for LG. In previous generations the brand's TVs typically stuck very closely to the reference picture characteristic after calibration. With the C6 we are still very close to the standard, but this subtle brightness boost is indeed noticeable in films and TV series.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at low settings. However, it has a drawback: if applied too aggressively, it can introduce undesirable artifacts on the screen. Therefore, it would be a good idea to experiment with this setting to find a happy medium between a smooth image and detail clarity.

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

Here the LG C6 has taken a real 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 considerable plus, because in this area LG's processor this year performs excellently. The "Smooth Gradation" function in particular works very well. With heavily compressed material it can effectively hide ugly banding and artefacts that often appear, for example, in lower-quality streaming. It's best to leave it set to "Low". That way the improvement is clear and the TV does not yet start blurring fine details. Higher settings smooth the image more aggressively but can already remove some of the natural texture of objects on the screen. Upscaling itself also performs very well. Lower-resolution content is sharpened correctly, edges look clean, and the processor quite effectively reconstructs fine details. In this respect the C6 is already very close to LG's best TVs and the differences compared with the G6 are small.

In this respect, 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 is actually the norm, and it is hard to expect anything more. However, the worst part is that the television does not have any features to improve motion smoothness. There is a lack of any supporting systems, both in films and in sports. We must 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, the motion can appear choppy or unclear. We do not have the option to enable any smoothers that would reduce this effect.

LG C6 received a panel with a maximum refresh rate of 165 Hz, which is great news above all for gamers using a powerful PC. In films, sport or on consoles we will of course make use of up to 120 Hz, but even then it is hard to fault the motion clarity. As befits an OLED, the panel's response time is almost instantaneous. Moving objects therefore do not leave the characteristic smearing or trails that we can still see on LCD televisions. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.

For films and television LG has also prepared the TruMotion motion smoothing system. In the user settings you will find two separate sliders. De-Judder primarily addresses low frame-rate content, that is mainly films and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or set a higher value if you want a very smooth image. De-Blur is useful for higher frame-rate material, chiefly sports broadcasts and 50/60 fps television.

Although the PUS7000 is not marketed as a gaming television, it does not perform as poorly in this category as one might expect. While it is true that we won’t find support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has ensured several important features that genuinely enhance the gaming experience on consoles. The most important of these are the VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This prevents the image from tearing and keeps it consistent even during sudden drops in frame rate while gaming. In contrast, ALLM is a solution that automatically switches the television to the lowest latency mode as soon as it detects 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 summoned on screen at any time. It allows for a quick preview of the current settings and connection status without interrupting gameplay, which is a very convenient solution.

LG has long focused heavily on gamers, and the C6 really lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can run at up to 165 Hz. There is also VRR from 40 to 165 Hz, ALLM and a properly working HGiG. A big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up Game Mode. It's rounded off by a Game Bar, from which you can quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is therefore one of those TVs that is really hard to fault. Whether you're gaming on a PlayStation, an Xbox or a PC, practically everything you could expect from a modern gaming TV is available here.
