Sharp GP7 vs LG OLED B5

In terms of HDR, Sharp GP7 can pleasantly surprise us. A maximum brightness of around 500 nits is the threshold at which the real benefits of high dynamic range become visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to clearer differentiation of elements in both bright and slightly darker scenes. Additionally, the DCI-P3 colour space coverage was around 95%, allowing for vibrant, visually pleasing colours. Of course, this is not the highest league, but considering this price range – it’s a big plus.

The LG B5 is a moderately bright OLED television. Regardless of the scene, it can generate around 500 nits of peak brightness. Interestingly, it achieves this even in full-screen shots saturated with white, where most OLEDs typically struggle. So is this screen suitable for HDR films? Indeed – and very much so, because such brightness allows you to truly feel the magic of HDR effects. However, it is 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 quite a significant difference. Fortunately, the television compensates with another advantage – excellent coverage of the DCI-P3 and BT.2020 colour gamut. As a result, HDR films look really colourful, vibrant, and impress even in more demanding scenes.

Upon removing it from the box, in movie mode, GP7 does not perform poorly at all. In HD materials, we noticed slight disturbances in white balance – drops in red and blue, which made the image have a somewhat greenish hue. This is evident, for example, on the faces of characters, which become less three-dimensional. The gamma is somewhat brightened in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone additionally comes to the fore, making the colours appear less natural. On the other hand, looking from the perspective of "straight out of the box," these settings are not bad – only minor adjustments are needed, and with the help of specific tools, we will try to improve them.

We tested the B5 in Filmmaker mode and... we would love to see more TVs like this straight out of the box. Truly. The white balance is set very well – there's practically nothing to complain about. Well, if one were to nitpick, one might notice a slight deficiency in blue, which makes the overall image seem slightly yellowish. But that’s just our editorial quibbling. Most of you probably wouldn’t even notice it. We also have minimal reservations about brightness management in HDR format. The EOTF curve – which is responsible for how the TV distributes brightness in a scene – is slightly below ideal. In practice, it may happen that the darkest parts of the image are displayed too dark and simply… disappear. But these are details that only come out in measurements. Generally: we are impressed. However, we also know that LG TVs respond very well to professional calibration. You can achieve almost reference-quality picture from them, so – while it's already very good out of the box – we allowed ourselves to go a step further and refine everything to perfection.

Calibration really makes a difference in Sharp GP7. After making adjustments, we achieved a better white balance in HD content, and the colours began to appear much more natural, with minimal deviations and without a noticeable dominance of individual hues. In 4K HDR, the change is not as spectacular, but still noticeable. The gamma has been brought to a more neutral level, although there remains an issue with a slight boost in the brightest details on the screen. The lack of control over dynamic tone mapping limits our manoeuvrability, but nonetheless, it is a significant step forward compared to the factory settings.

We must admit that we didn't have much work with the LG B5. It's one of those televisions that look good right from the start, but after calibration… they can really impress. The white balance was brought to almost perfect levels – to the point of errors that are invisible to the human eye, unless you are a professional colourist with a magnifying glass at the screen. We also managed to master the tendency of the television to slightly dim the darkest details, particularly in HDR scenes. After proper tuning, everything looks cohesive: black remains deep but does not consume information. Highlights maintain their natural sparkle, and colours align with the director's vision. This is truly one of those models that shows you don't have to spend a fortune to have an almost reference-quality picture. If you can opt for professional calibration – it’s definitely worth it in the case of the B5.

The television is quite capable of scaling lower quality content. Our test patterns were well reproduced, and although there was minimal banding on fine, delicate shapes (for example, thin branches), it still looked satisfactory. Additionally, Sharp GP7 offers a "10-bit colour reproduction" feature to smooth tonal transitions in poor quality materials. It is useful, but at the cost of some details, so we recommend turning it on only when we are truly watching something subpar.

LG B5 really positively surprised us in terms of handling lower quality content. Thanks to the enhancement and smoothing features, materials in HD resolution or even SD gain a second life. Importantly – when this option is activated at the "low" or "medium" level, we do not feel that the image is artificially softened or smoothed out unnecessarily. Details remain intact, film grain does not disappear, and the edges of objects do not look washed out 😉. This is truly a useful tool – especially if you are watching terrestrial television, archival materials, or content from YouTube in lower resolutions. The image is clear, coherent, and simply pleasant to the eye.

Scaling as such works very well – even content of poor quality is reproduced with surprising fidelity. Unfortunately, there was a slight hiccup. Although the menu contains the option to disable overscan, the television still has issues with correctly displaying images of very low resolution. It may seem like a detail, but when watching older materials – it can be irritating.

With a 60 Hz panel and an average response time, it’s hard to expect miraculous smoothness. In dynamic tests, such as the one with the “little green man”, it’s evident that the picture can stutter and occasionally lose sharpness. For watching films and series, this is acceptable, especially as you can make use of a motion smoother with three levels of adjustment. However, if we are keen on ultra-smooth sports broadcasts or super-responsive gaming, we may feel unsatisfied.

LG B5 is a television with a 120 Hz OLED panel. It may not sound as impressive as the marketing claims of “144 Hz” or “165 Hz” found in gaming monitors, but honestly? The smoothness is excellent nonetheless. The picture is sharp, fluid and simply enjoyable to watch – even when there is a lot happening on screen. The organic panel does its job – the pixel response time is almost instantaneous, meaning there’s no sign of smearing or blurring that can spoil dynamic shots. Sport, fast-paced games – everything looks clear and distinct.

We also have the classic LG smoothness enhancer, TruMotion. This allows you to smooth out films shot at 24 frames per second – which, to put it bluntly, is 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 a cinematic look – with a slight judder, but without any artificiality. Higher settings? A soap opera effect is guaranteed. Fortunately, LG gives you the option to tune everything to your liking.

Let's not kid ourselves – GP7 Sharp is not a television for the most demanding console gamers. Yes, it has ALLM which automatically switches the TV to low latency mode, but it lacks VRR or G-Sync. We also won't find any advanced menu to assist in selecting settings during gameplay. Dolby Vision in games? It's there, but with such a high input lag that it's hard to speak of comfort. If we play occasionally and are not aiming for the highest standards, it can be managed, but fans of technological innovations will be disappointed.

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