LG OLED G5 vs Samsung Neo QLED QN70F / QN74F / QN77F

LG G5 with the new Tandem OLED matrix brings the biggest change in terms of the brightness of the television. And it's substantial. This is truly an astronomically bright OLED. In every scene tested – whether it was point lights or full-screen whites from the film The Meg – the brightness on the G5 exceeded 2000 nits. Just a year ago, such values on an OLED were simply unimaginable. And here we are – the G5 is approaching, and at times even surpassing, the best Mini-LEDs on the market. A new feature of the Tandem OLED matrix is also the expanded colour gamut – and here the LG G5 performs almost perfectly. DCI-P3 reaches a full 100%, and BT.2020 is maintained at around 83%. These are some of the highest values currently available on the market – it's hard to find any other television that comes close to such results, unless we are talking about the best displays with QD-OLED panels. The G5 has nearly reference-quality HDR – both in terms of brightness and colour saturation. This is an OLED that can truly shine – and not just figuratively.

The QN70F is a television that can pleasantly surprise when it comes to brightness. In ideal testing conditions, it reaches up to 800 nits, which – for this price range – is a really solid figure. Of course, this result comes from measurement charts, so we decided to check how it performs in practice, with real films. Here, the television somewhat tempers its capabilities. In most tested scenes – for example, in "The Meg" – the actual HDR brightness hovered around 500 nits. This is still a decent result, allowing for enjoyment of HDR effects, although it is far from perfect. On the other hand, we have a QLED screen with a layer of quantum dots, which means very good colour reproduction capabilities. The colours are vibrant and saturated. The QN70F covers about 94% of the DCI-P3 colour space, and in the wider BT.2020 palette, it exceeds 75%, so in this respect, there is nothing to be ashamed of.

Our test unit, the LG G5, struggled with certain issues in the factory Filmmaker mode. And although most people might have found the picture acceptable, we knew that this television was capable of much more. This mode had a clear excess of blue tint in the white balance, resulting in a significantly cooled image – particularly in HDR modes, where there was additionally a lack of red. The picture appeared cold, and its sharpness was artificially boosted and unnatural. Another significant issue was the brightness characteristics. In SDR content, the situation wasn't the worst, aside from a slight dimming of the entire image. However, it performed much worse in HDR materials – due to improper brightness management, the smallest details could completely disappear from the image, while larger, bright elements looked overexposed and lacking in gradation. Fortunately, the G5 supports calibration using 3D LUT (a tool for professionals for colour calibration), so we decided to make use of its professional capabilities and see what it could really do. Because although it wasn't tragic even before calibration, the potential of this television definitely deserved more.

We tested the QN70F in its best default picture mode, which is Filmmaker Mode. I must admit that in this particular test unit, the factory settings performed quite well. The image was calm, natural, and despite minor deviations – pleasant to watch. The biggest flaw was a slight dominance of red in the white balance, which caused a slight pinkish hue across the entire scene. However, this was not a glaring defect – rather subtle and only noticeable when directly compared to a properly calibrated screen. A somewhat larger issue arose in the brightness characteristic. The television tends to underestimate the brightness of parts of the image that should be displayed more brightly. As a result, some details can appear slightly muted – not so much lost completely, but not resonating as clearly as they should. Nonetheless, as far as televisions in this category and in these settings are concerned – we consider the result a good starting point for further calibration.

After performing the calibration process using professional tools, we can confidently state that the LG G5 offers nearly reference-quality image. Most of the errors related to white balance and the ColorChecker test are below a value of 2, which is a phenomenal result, practically imperceptible to the human eye. And while one could still nitpick that in HDR films the television still has a tendency to slightly dim the smallest elements of the image, in practice this does not negatively affect the overall impression. Kudos to LG, as once again they provide the user with enormous possibilities for adjusting their display – and this, combined with the very good parameters of the panel itself, results in an image that is truly hard to beat.

After calibration, the QN70F shows that it can offer a truly high level of colour reproduction. The white balance was nearly perfectly aligned, and the values in the Color Checker test dropped below level 3 – meaning below the threshold at which the average eye can perceive differences. The image looks natural, and the colours are faithfully rendered, without excessive saturation or the coolness known from factory settings. It must be admitted that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after proper adjustment, can come close to significantly more expensive models in terms of colour accuracy. The only thing that can still be nitpicked is the brightness characteristic. There is still a tendency to lighten the smallest areas of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final effect definitely deserves recognition.

Upscaling and digital image processing in the LG G5 are quite impressive. The television handles lower quality content very well, especially when the "Smooth Gradation" feature is set to a low level. In this mode, it effectively removes unwanted artifacts and issues with visible tonal transitions. It may also slightly smooth out some desirable details, such as the subtle texture of clothing or skin, but importantly – it does not remove film grain, so it's difficult to speak of a serious compromise here. This is one of those options that is definitely worth enabling.

The G5 also performs well with upscaling, which improves the quality of older materials. The test image with the model looked really solid – slight jaggedness was visible, but that's an effect that cannot be completely avoided. Additionally, there were no problems with overscan, which – contrary to appearances – is not at all obvious, even in 2025.

Samsung QN70F offers a distortion reduction feature that enhances the smoothness of tonal transitions. In "Standard" mode, it works quite well – it smooths out problematic transitions without significantly interfering with the structure of the image. Film grain is somewhat reduced, but details such as texture and skin structure remain visible. The "High" mode is much more aggressive. The smoothing is stronger, but it comes at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or completely turning this function off. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to scaling low-quality content, the QN70F performs very well. Tests with lower resolution images were really very good. Despite slight edge ringing, everything looks clean and clear, even if the original content was very poor. It’s just a pity that the television has an issue with overscan, which cannot be completely turned off. As a result, images with very low resolution may be slightly cropped, which is mainly noticeable on subtitles or interfaces.

The motion smoothness on the LG G5 is simply phenomenal. The television is equipped with a 165 Hz refresh rate panel, and this, combined with the instant response time of the OLED matrix, delivers incredible results. The image does not tear or stutter like on traditional LCD televisions. Like most LG models, the G5 is equipped with a motion smoother, which can be useful when watching films – we are, of course, referring to the TruMotion mode. With the "De-Blur" and "De-Judder" sliders, we can adjust the smoothness of older materials according to our own preferences, whether we want to maintain the characteristic film stuttering or lean towards a more fluid, television-like effect.

The QN70F is a television with a refresh rate of 144 Hz, which in itself places it among the top when it comes to image fluidity. Whether we are watching dynamic sports broadcasts or playing on a console – the picture looks very good. There is no sense of stuttering, choppiness, or the typical "tearing" associated with weaker models during fast motion. Samsung also allows you to adjust the fluidity to your own preferences. In the picture clarity settings, we find options such as blur reduction and judder reduction – each of which we can adjust independently. This is especially useful when watching content with a lower frame rate and wanting to give it a smoother, more theatrical character – or conversely, to maintain the natural cinematic "feel" of 24 frames.

Features for gamers? Perfect. That should be sufficient for you to know what level we are dealing with here. The G5 is a television designed with gamers in mind, so we will find literally everything you could expect from a gaming screen. There is a Game Bar, there is support for high resolutions with high refresh rates – that is, 4K at 120 Hz, and even more, as the panel has a refresh rate of 165 Hz (which PC gamers will benefit from). The television supports variable refresh rate (VRR), automatic low latency mode (ALLM), and also correctly handles HDR in games thanks to the HGiG function. All of this adds up to one of the best sets of gaming features available on the market. Well done, LG.

Samsung QN70F is truly a solid choice for gamers. Here we have as many as four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at a refresh rate of 144 Hz. Additionally, we have all the essential features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar that provides information on mode, resolution, and frame rate. Also noteworthy is the Game Motion Plus feature, which allows for the addition of artificial frames to games running at 60 fps or lower. It works surprisingly well and improves the smoothness of gameplay in many titles – especially those where consoles struggle to maintain a stable frame rate – without significant lag.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

Unfortunately, there are also some drawbacks. The lack of support for Dolby Vision mode is not surprising – that is a standard at Samsung. But the absence of the HGiG feature is much more disappointing. What's worse, it was removed by a software update, which may come as a shock to users who previously relied on it. Without HGiG, it is impossible to manually set the maximum HDR brightness from the console, resulting in some games appearing slightly washed out – especially if the television misinterprets the tonal range. Why did Samsung, a brand that has set the standards for gaming features for years, choose to take such a step? It's hard to say. At the time of writing this review, the tested television was running on software version 1110 – and to be honest, if you care about full support for gamers, it’s better to temporarily refrain from updates.
