LG OLED B5 vs Hisense U7Q

LG B5 is a moderately bright OLED TV. Regardless of the scene – it can generate about 500 nits of peak brightness. And interestingly, it does this even in full-screen shots flooded with white, where most OLEDs usually struggle. So, is this screen suitable for HDR films? Yes – absolutely, because such brightness really allows you to feel the magic of HDR effects. However, it’s worth noting that compared to last year's B4 model, the new B5 is darker – by about 100 nits. It may seem like a small amount, but at such average peak values, it makes a significant difference. Fortunately, the TV makes up for it with another strength – excellent coverage of the DCI-P3 and BT.2020 colour gamuts. This means HDR films look truly vibrant, lively, and impressive even in more demanding scenes.

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good outcome when it comes to brightness and overall HDR quality. Unfortunately, we have to disappoint you a bit here.

The U7Q is quite a bright television – under the best conditions, it can reach around 800 nits, which indeed impresses in some scenes, especially in scenes like those from the movie The Meg. Bright segments can shine, and the HDR effect is noticeable. The problem arises when very small, bright elements appear on a dark background – for example, in Sicario 2 or in the second scene from Life of Pi. At such moments, the dimming algorithms operate too aggressively. Yes, the blacks look great at that point, but the brightest spots can almost completely disappear, causing the HDR effect to vanish and details to be barely visible. That’s just the charm of this technology in this price segment.

As a consolation, it is worth mentioning that the U7Q is marketed as a QLED (in practice, a PFS layer is used, which operates very similarly), and it can indeed display a wide colour gamut – a DCI-P3 coverage of around 94% is a very good result for this class.

B5 was tested in Filmmaker mode and… we’d love to see more TVs like this right out of the box. Seriously. The white balance is very well set – there’s practically nothing to nitpick. Well, if you really want to, you might notice a slight deficiency in blue, which can make the overall picture have a slightly yellowish tint. But that’s just our editorial nitpicking. Most of you probably won’t even notice. We also have minimal reservations about brightness management in HDR format. The EOTF curve – which is responsible for how the TV distributes brightness across the scene – sits just below ideal. In practice, it may happen that the darkest parts of the image appear too dark and simply… disappear. But these are details that only come out in measurements. Generally: we are impressed. But we also know that LG TVs respond very well to professional calibration. You can extract nearly reference-quality picture from them, so – although it’s already very good out of the factory – we took the liberty to go a step further and fine-tune everything to the max.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This mode is supposed to provide the most "cinematic" experience that aligns with the creators' intentions – straight out of the box. Unfortunately… even this professionally sounding name doesn’t guarantee a perfect image.

In our unit, the problem lay in the poorly set white balance. In both HD and 4K content, the image had too much blue and red, resulting in a slightly pinkish hue on the screen. It didn’t look terrible, but it was noticeable – especially in bright scenes and on white backgrounds. That alone could have been forgiven, but the biggest issue is managing brightness in HDR content. The EOTF curve from the measurements confirms what we saw earlier during scene tests: the television can overly dim the smallest bright elements, causing them to nearly disappear, or conversely – excessively brighten the brightest parts, which affects the naturalness of the image.

We have to admit that we didn't have much work with the LG B5. It's one of those TVs that look good right from the start, but after calibration… they can really impress. The white balance was nearly perfect – down to a level of errors invisible to the human eye, unless you're a professional colourist with a magnifying glass at the screen. We also managed to control the TV's tendency to slightly dim the darkest details, especially in HDR scenes. After proper tuning, everything looks cohesive: blacks remain deep but don't swallow information. Highlights maintain a natural sparkle, and colours are true to the director's vision. This is truly one of those models that show you don't have to spend a fortune to have an almost reference-quality image. If you can opt for professional calibration – it's definitely worth it for the B5.

Thanks to specialist tools, we managed to correct the colour quality in SDR content to almost perfection. In materials with lower dynamics, delta E errors dropped below 0.5, which can be considered an almost reference result. The picture on television, YouTube, or classic Full HD looks really good after calibration. Well then – but where was it not so easy to improve the image? Primarily it concerns HDR quality content. Although we managed to somewhat "tame" the white balance and eliminate pink tints in most scenes, unfortunately, we did not have full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of overly strong dimming or brightening of details that calibration simply could not eliminate. And although the overall reception of content is much better, one must reckon that the U7Q will always have something to say at the end with "but".

LG B5 really surprised us positively in terms of handling lower quality content. Thanks to the enhancement and smoothing features, HD or even SD materials come to life. Importantly – when this option is turned on at the "low" or "medium" level, we don’t get the impression that the image is artificially softened or overly smoothed. Details remain in place, film grain doesn’t disappear, and the edges of objects don’t look washed out 😉. It’s a really useful tool – especially if you’re watching free-to-air TV, archival materials, or content from YouTube in lower resolutions. The picture is clear, consistent, and simply pleasant to the eye.

Upgrading as such works very well – even low-quality content is reproduced with surprising fidelity. Unfortunately, it’s not without a minor hiccup. Although the menu has an option to turn off overscan, the television still has issues correctly displaying very low-resolution images. It’s a minor detail, but when watching older materials – it can be annoying.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those with limited source quality. The U7Q has been equipped with a feature called “Smooth and Gradient Image,” but unfortunately… it works very poorly. In the “Low” option, the effects are practically unnoticeable, and other settings smooth out the details but don’t improve tonal transitions. The only positive thing is that the feature doesn’t interfere with the film grain, so it doesn’t ruin the natural structure of the image.

Fortunately, content scaling performs quite well. The image is not overly sharpened, there is no artificial clarity – and while it’s known that this isn’t the level of high-end TVs, the U7Q has no problem displaying really old content in a completely acceptable manner.

LG B5 is a TV with a 120 Hz OLED panel. It may not sound as impressive as the marketing terms "144 Hz" or "165 Hz" commonly found in gaming monitors, but honestly? The smoothness is still excellent. The picture is sharp, fluid, and simply enjoyable to watch – even when there’s a lot happening on screen. The organic panel does its job – the pixel response time is almost instantaneous, which means there’s no risk of ghosting or blurring that can ruin dynamic shots. Sports, fast-paced games – everything looks clear and distinct.

We also have the classic LG motion smoother, TruMotion. It allows you to smooth out movies shot at 24 frames – in other words, most of what you watch on Netflix or from Blu-ray discs. If you set lower values on the “De-Judder” slider, you’ll get a picture closer to the cinematic experience – with a slight judder, but without artificiality. Higher settings? Soap opera effect guaranteed. Fortunately, LG gives you the choice, and you can tune everything to your liking.

U7Q is a truly fast TV, much like its more powerful version “PRO”. At 4K resolution, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD, you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it’s worth appreciating – it’s a rare feature in this price segment. Right from the start, it’s clear that the U7Q has been designed with dynamic content in mind, such as games or sports. In films, we’re not left “out in the cold” either – the U7Q offers an “Ultra Motion Smoothness” feature, where with two sliders, you can adjust whether you want a smoother, theatrical picture, or something closer to cinematic style with a visible frame. It’s good that, like most manufacturers, we have a choice here and can customise it to our own preferences.

There are already a few TVs on the market with the "for gamers" label that don't really understand what that means. The LG B5 is not one of them. Everything here is spot on – there are four HDMI 2.1 ports, 120 Hz, there’s VRR and ALLM, and there’s also a Game Bar that's actually useful, not just looking good in the brochure. You plug in a console – it works. You set it to 4K at 120 Hz – it works. You have an Xbox and want to play in Dolby Vision – it works too. And it's not just "theoretically supports," it actually turns on, looks good, and you don't have to fiddle with settings for half an hour. Plus, there’s the HGiG picture mode, which LG has implemented correctly – meaning HDR in games doesn't turn the screen into a strobe light, but shows exactly what it should. There are no surprises, no strange limitations, no "buts." And you know what? That's how it should be. Cheers to the LG B5!

The Hisense U7Q is a TV designed with gamers in mind – and you can see that straight away with its gaming capabilities. It has practically everything you could wish for: Variable Refresh Rate (VRR) – check, Auto Low Latency Mode (ALLM) – check, and high refresh rates of up to 240 Hz in Full HD, along with support for various resolutions, not just 4K. It’s truly an impressive set of features that makes the U7Q perform well with both fast-paced shooters on consoles and more demanding titles on PC. Of course – like most Hisense models – it lacks a proper implementation of the HGiG feature. It’s a shame because HGiG allows the console's brightness to be adjusted to the specific TV, which in practice makes it easier to display HDR games according to the creators' intentions. Without this, you just have to deal with some limitations in the final HDR image in games.
