Hisense U7Q PRO vs LG OLED C6 (WOLED)

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price range. Such brightness – at least in theory – allows for HDR content to be displayed as intended by the creators, even in more demanding scenes with strong lighting. In practice, it is often very good, but not always perfect. In bright scenes with large areas – like the test chart with intense sunlight from the movie "Pan" – the U7Q PRO makes a huge impression. It can almost dazzle with its brightness, which is definitely an advantage in the context of HDR content. Unfortunately, it doesn't always manage to maintain this when many small bright details appear on a dark background. In such moments, the local dimming algorithms choose to dim some bright elements to maintain good black levels – and the side effect is that some details simply disappear from the frame. This is a classic compromise in mini-LED televisions – and the U7Q PRO is no exception. However, with such a large number of dimming zones, one could have hoped for a slightly more mature algorithm responsible for their control. Fortunately, the overall perception of HDR content is decidedly positive. The U7Q PRO is not only bright but also colourful, thanks to the PFS LED (QLED) coating, the coverage of the DCI-P3 colour palette is at 95%, while BT.2020 is around 73%.

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 U7Q PRO in the best possible picture mode offered by this model – Filmmaker Mode. And indeed, this mode performs the best in terms of colour reproduction. However, that doesn't mean it's perfect. In our test unit, both in SDR and HDR content, the image had a slightly cooler tone. The white balance was skewed towards blue, giving the overall impression of being a bit "colder". It may not be glaring, but it is definitely noticeable – especially on white backgrounds, which seemed slightly bluish rather than neutral. Additionally – as we mentioned earlier – the television has a tendency to slightly brighten and oversaturate the image, which is also confirmed by the gamma and EOTF graphs. All this together means that without calibration, the image can appear somewhat unnatural – too cool, with slightly exaggerated dynamics. Therefore, we decided to carry out our own calibration – and you can see its effects and graphs below.

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.

Thanks to the calibration, we managed to tame the white balance in SDR and HDR content. In the case of SDR materials, the effect is really very good – the image becomes neutral, cohesive, and simply pleasant to take in. Everything looks as it should.

HDR performs a bit worse. Although the white balance appears correct and the image overall gains in naturalness, unfortunately, the delta E errors remain noticeable. Why? Because Hisense does not give us full control over how the television manages brightness in HDR mode with the U7Q PRO model. This is where the limitation comes into play. When we look at the EOTF curve for HDR content, we can clearly see what we mentioned earlier – at the beginning of the graph, there is a distinct drop, meaning the television darkens the smallest areas more than it should. On the other hand – the brightest elements can sometimes be overly bright. As a result, some details get lost, others are too aggressive, and overall control over brightness does not always match what we are trying to achieve during calibration.

Does the image look better after calibration? Definitely yes, in terms of colour. But when it comes to managing brightness in HDR, we have to accept that the Hisense U7Q PRO will do it in its own way.

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.

If someone happens to come across older materials where the colour banding issue occurs – Hisense has a solution for that. In the U7Q PRO, we find a function called "Smooth and Gradient Image". Set to the "Medium" level, it works really well – removing most issues with gradation while not smoothing out the entire image, like blurring in Photoshop. 😉 Film grain remains, details do not disappear – this is exactly how it should work. Well done on the implementation!

As for upscaling weaker materials, it is simply good. It is not at the level of the most expensive televisions with advanced upscaling, but older content looks good. There is minor aliasing at very low resolutions, but this is completely normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect, the image is neither cropped nor artificially stretched.

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.

“Speed” – this word came up most often during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which is impressive in itself – especially since we are talking about a model in the mid-range price category. Of course, PC gamers will benefit the most from its full capabilities, but even with everyday viewing, it's clear that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the fluidity of films that were originally recorded at 24 frames. In the menu, we find a slider that allows us to adjust the effect to our own preferences – from a more cinematic look, with subtle motion, to stronger smoothing with the characteristic “telenovela 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.

The Hisense U7Q PRO is a television that seems almost designed with gamers in mind. It has practically everything one could expect from a gaming display: variable refresh rate (VRR), automatic low latency mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there is a clear and quite functional Game Bar, as well as a well-implemented Dolby Vision GAMING mode that works seamlessly with Xbox Series S and X consoles.

Sounds like perfection? Well, almost. Unfortunately, Hisense has still not implemented the HGiG feature, which means the system limitation of tone mapping on the television side. This means that when configuring HDR brightness on the console, we do it "by eye" or search for settings in online guides, as the display does not show the actual range of its brightness. It’s a pity – because HGiG indeed makes it easier to match the console to the television and helps avoid overexposure or overly dark scenes in HDR games.

Fortunately, the other features work very well. Input lag is low, responsiveness is excellent, and the handling of other functions is impeccable. And while not everything worked perfectly, the U7Q PRO can still be recommended to gamers without hesitation.

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.
