LG OLED B5 vs Samsung Q7F

LG B5 is a moderately bright OLED TV. Regardless of the scene, it can generate around 500 nits of peak brightness. And interestingly, it does this even in full-screen shots flooded with white, where most OLEDs usually fall short. So, is this screen suitable for HDR movies? 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 model B4, the new B5 is darker – by about 100 nits. It may seem like a small difference, but at such average peak values, it makes quite a significant difference. Fortunately, the TV makes up for it with another advantage – excellent coverage of the DCI-P3 and BT.2020 color gamut. As a result, HDR movies look really colorful, vibrant, and impressive even in more demanding scenes.

Unfortunately, the Samsung Q7F is not one of the bright televisions, and this directly affects the quality of HDR movies. The peak brightness of the panel is only about 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it hard to talk about any "wow effect" that usually accompanies us while watching such films. During testing movie scenes, the image simply looked dim, and brightness almost invariably hovered around the mentioned 250 nits. The worst performance was observed in shots with small, intensely glowing elements – the applied global dimming technique reacted very aggressively, dimming the entire screen to maintain the black effect. On the plus side, it is worth noting the presence of a QLED coating that expands the color palette. As a budget QLED model, the Q7F performs quite decently here: its DCI-P3 color coverage is about 93%, and BT.2020 reaches 70%. This means that colors, despite the low brightness, can look quite vivid and attractive.

We tested the B5 in Filmmaker mode and... we would like to see more TVs like this straight out of the box. Really. The white balance is set very well – there is practically nothing to complain about. Well, if one were to be very picky, one might notice a slight deficiency in blue, which makes the overall picture have a slightly yellowish tint. But that’s just our editorial nitpicking. Most of you probably won't even notice it. We also have some minor reservations about brightness management in HDR format. The EOTF curve – that is, the one responsible for how the TV distributes brightness in a scene – is slightly below the ideal. In practice, it can happen that the darkest parts of the image may be displayed too dark and simply... disappear. But these are details that only come out in measurements. Overall: we are impressed. But we also know that LG TVs respond very well to professional calibration. They can produce nearly reference-quality images, so – even though it's already very good out of the box – we allowed ourselves to take an extra step and fine-tune everything to perfection.

The factory color reproduction in the Samsung Q7F definitely isn't one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There's too much red on the screen, while blue is noticeably lacking. The effects of this are very easy to see – white, instead of being neutral, takes on warm, almost slightly orange tones. Over time, this makes the entire image look somewhat unnatural, and bright areas of the scene can seem unrealistic. The problems become even more apparent in HDR content. The graphs show that the TV has significant errors in the Color Checker palette, which translates to visible inaccuracies in the real image. In practice, this means that colors are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can appear dimmed. As a result, the image seems flattened, and instead of helping to bring out details, contrast only highlights its own limitations. This is particularly frustrating in HDR materials, as every detail matters there. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the brightening or, conversely, suppresses elements that were meant to draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we get more of a simplification effect.

We must admit that we didn't have much work with the LG B5. It's one of those TVs that looks good right from the start, but after calibration… it can really impress. The white balance was brought to almost perfect levels – to a degree of error invisible to the human eye, unless you are a professional colorist with a magnifying glass at the screen. We also managed to control the TV's slight tendency to dim the darkest details, especially in HDR scenes. After proper tuning, everything looks coherent: the black is still deep, but not information-hungry. The highlights retain a natural sparkle, and the colors align with the director's vision. It's really one of those models that show you don't have to spend a fortune to get almost reference-quality image. If you can decide on professional calibration – it's definitely worth it for the B5.

After professional calibration, we managed to bring the Q7F in order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colors appear natural, and errors in the color palette have dropped to values that are practically invisible to the eye. The gamma behaves excellently, and the only minor drawback is a slight brightening of smaller elements, which results from the lack of local dimming. For everyday TV watching or standard quality films, the Q7F performs surprisingly well.

It was much more difficult to tame HDR content. Despite adjusting the white balance, the television continues to manipulate brightness significantly, causing scenes to sometimes look unnatural – what was meant to be subtly darker can end up being overly brightened, and bright parts of the image sometimes appear dull. The final effect is better than in the factory settings, but it is evident that the design limitations of the Q7F do not allow for fully utilizing the potential of HDR materials.

LG B5 really surprised us positively in terms of dealing with lower quality content. Thanks to the enhancement and smoothing features, HD or even SD materials get a new 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 intact, film grain does not disappear, and object edges do not look washed out 😉. It's a really useful tool – especially if you watch terrestrial TV, archival materials, or content from YouTube in lower resolutions. The image is clean, cohesive, and simply pleasant to the eye.

Upscaling as such works very well – even content of poor quality is rendered with surprising fidelity. Unfortunately, there was a small hiccup. While the menu offers an option to turn off overscan, the television still struggles to display very low-resolution images correctly. It’s a minor detail, but when watching older materials – it can be annoying.

Upscaling and digital image processing in the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older movies or terrestrial TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it looks rather unrefined. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients remains. It's a bit disappointing because we could have expected more from a model that is aimed at users looking for a display for SDR content.

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

We also have LG's classic motion smoother, TruMotion. This feature allows you to smooth out films shot at 24 frames per second – in other words, most of what you watch on Netflix or on Blu-ray discs. If you set the “De-Judder” slider to lower values, you'll get an image 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 as you like.

Motion blur and motion fluidity in the Q7F is probably the most budget-conscious element of this TV. The 60 Hz panel is noticeable, with blur being quite evident, especially in dynamic scenes, and it's rather difficult to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long tail, and the ball in a football match would leave trails behind it.

On the plus side, the presence of motion smoothing is commendable. It really makes a difference in movies - especially since most materials are recorded at 24 frames. Here we can decide for ourselves whether we prefer a more "cinematic" image, with the slight jerkiness characteristic of cinema, or a smoother, more "television-like" one. This actually works quite well and helps improve the viewing comfort for series or movies.

There are already a few televisions on the market with the label "for gamers" that don’t really understand what that means. The LG B5 is not one of them. Everything here is right – there are four HDMI 2.1 ports, it has 120 Hz, VRR and ALLM, and it also has a Game Bar that is actually useful, not just looks good in the promotional folder. 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 not in the sense of "it theoretically supports it," but rather it really turns on, looks good, and you don’t have to fiddle with the settings for half an hour. On top of that, there’s the HGiG picture mode, which LG has implemented correctly – meaning that HDR in games doesn’t turn the screen into a flashlight 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. Kudos to the LG B5!

Features for gamers in the Samsung Q7F is a topic that evokes quite a bit of mixed emotions. On one hand – no sensible person expected miracles here, after all, it's a 60 Hz television, and it was clear from the beginning that it wouldn't be a device to extract the maximum from a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it's natural that we wanted to see them in practice. At the start, it's quite decent. The automatic game mode (ALLM) works, so there's no need to manually fiddle with the settings; the console switches the TV to low latency mode by itself. Additionally, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, a relevant icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the function remained dead and could not be activated in any way. The issue with HGiG is even more painful; this option was actually available at the beginning, but after a software update, it disappeared completely, which is simply unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play more mellow titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television intended for gaming, and it's better to be aware of this before purchasing.
