LG UR781 vs Panasonic W85

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is similar to levels typical for SDR, causing HDR effects to be insufficiently pronounced, and the image may appear less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that manage better with a wide colour gamut. In practice, this can make the image less vibrant and dynamic, and HDR effects will not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurately reproducing colours in HDR mode, resulting in content that may look less vivid.

Unfortunately, we do not have good news here. The Panasonic W85B is rather dim – its peak brightness does not exceed 300 nits, so it’s hard to talk about any true HDR effect. In practice, this means that scenes which can “shine” and make an impression on other screens simply look like ordinary SDR with a slight boost in colours here. Our measurements and film tests confirmed this – regardless of the content, the W85B will not extract anything more from HDR. Therefore, if someone is looking for a television specifically for HDR, it is better to look towards other models. As consolation, the fact remains that in terms of colours, the W85B performs quite well. It is a QLED television, so its colour gamut coverage is wide, and most films and series look natural, without a distinct “washed-out” effect. The colours are saturated, so in everyday viewing, there is no sense that something is strongly amiss.

The colour reproduction in LG UR781 in Filmmaker Mode, which although is the best mode available from the factory settings, is not without its flaws. Firstly, the issue is white balance, where the graph shows dips in blue colour levels. This phenomenon results in a shift of hues towards yellow tones, causing the image to appear warmer than it should. Such deviation means that the colours on the screen are not naturally reproduced, which can be particularly noticeable in scenes with a white or neutral background. This can be confirmed by the Test Color Checker, which showed that some colours "shift" into other shades, meaning that the LG UR781 television does not display colours in accordance with reality. This distortion can affect the visual experience, making movie scenes seem less realistic, and details might be displayed in inappropriate colours, negatively impacting the overall image quality.

In terms of contrast, the analysis of the gamma graph revealed drops to a level of 2.0, whereas the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in certain scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was observed at the beginning. This phenomenon can result in excessive brightness boost in the brightest parts of the image, leading to loss of detail in very bright scenes.

When testing the Panasonic W85B, we obviously started with Filmmaker mode, as this is today’s gold standard when it comes to watching content “as the director intended.” The problem is that this television is quite far from those intentions. The biggest issue turned out to be an excess of red – both in SDR and HDR. The image often appeared too warm because of this, and in some scenes, it was almost “blazing.” Additionally, there is the issue of brightness management. When we looked at the gamma or EOTF charts, it was clear as day that in most scenes, the television brightens the image more than it should. The effect was simply predictable. Details can get lost, there is flattening, and highlights are blown out across the entire screen. We know, of course, how to correct this, but it must be said honestly that it requires a lot of work during calibration. Out of the box, the W85B does not provide a picture close to reference – it is rather a television that will always interpret colours and brightness a little “in its own way” without professional adjustments. Unfortunately, this is to the viewer’s detriment.

After calibration, the colour representation in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across various scenes. The gamma has also been adjusted, providing more precise detail in the shadows and highlights of the image. As a result, the LG UR781 television performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is worse for HDR content. The LG UR781 television does not support a wide colour gamut, which limits the depth and richness of colours that HDR can offer. The EOTF curve deviates from the ideal, resulting in excessive highlighting of details in the bright parts of the image. Unfortunately, this results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts the quality of HDR images, causing dynamic range effects to be not fully realised, and colours to appear washed out.

Despite some shortcomings in HDR mode, the television has improved significantly after calibration, especially in SDR content. The improvement in white balance and gamma has greatly enhanced image quality, providing a more natural and cohesive colour representation. Compared to its state before calibration, the difference is clear, and the LG UR781 television now offers better performance in everyday use, particularly in the standard dynamic range.

Fortunately, calibration made a significant difference for the Panasonic W85B, particularly in SDR content. Here, the improvement was really noticeable – we managed to balance the whites and somewhat tame the tendency of the television to excessively brighten the entire image. The picture became more coherent, and the colours gained a naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has visible issues with green saturation, but overall, we evaluate the post-calibration effect in SDR very positively. The situation is a bit different with HDR. Here too, we managed to reduce the tendency to warm up the entire scene, so the image performed significantly better than in the factory settings. However, the same issue we mentioned earlier is still evident – the television interprets the image too much "on its own" and brightens the entire screen. The lack of local dimming only exacerbates this effect. In summary, briefly in SDR content, the W85B performs really well after calibration and is more than suitable for daily viewing. However, in HDR, even after adjustments, it remains difficult to unequivocally recommend it for serious viewing sessions.

Now let’s address the function of smoothing tonal transitions and its impact on overall image quality. As illustrated in the photo on the left, this function performs exceptionally mediocrely; we selected the "low" level, which does not improve quality but also does not blur the film grain. There is the option to increase the power of this function, which would soften the gradation; however, one must reckon with the fact that the image will be too softened in some scenes.

On the other hand, regarding image scaling, the television does not perform exceptionally, which can be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpness boost, which makes the image appear sharper, but this primarily results from the overlay of artificial contours. For some users, this can be an advantage, as they prefer more vivid, accentuated details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural look to the image.

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or prominent contours. However, the situation is worse when it comes to lower resolution materials. It is precisely there that the television has the most difficulty with "enhancing" the image. The lack of any option in the menu that would allow for improving gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with colour blending.

Fortunately, upscaling, or raising the quality of lower resolution content, performs much better. This is definitely a strong point of this model – the image is scaled cleanly and in detail, and the television handles this better than one might expect from such an inexpensive piece of equipment. This is thanks to the HCX processor, which Panasonic has been developing for years, and it is noticeable that even in the lower series it can do a good job.

The LG UR781 television offers quite decent smoothness for films, thanks to the "True Motion" option, which allows users to adjust the level of motion smoothing on a scale from 0 to 10. The user can choose whether they want to preserve a more traditional, cinematic effect with subtle judder (lower settings) or prefer a smoother, theatrical image that, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and games, the LG UR781 television performs worse. The television has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, it can improve fluidity in films but cannot reduce motion blur. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that quick movements of objects become blurred, and the response time of the panel is too long, negatively affecting clarity in fast scenes. As a result, the television may not meet the expectations of gamers and sports fans who are looking for a smooth, clear image without motion blur.

At first glance, everything looks good – the Panasonic W85B has a 120 Hz panel and even a 144 Hz mode, so it seems that it should cope well with smooth motion. The problem arises when we look into the settings. The options for improving fluidity are supposedly present in the menu, but in practice… they don't change anything. No matter what we choose, the image looks the same. On top of that, there is a lack of BFI, or the black frame insertion mode, which on many televisions helps sharpen motion. And suddenly it turns out that despite the strong panel, the W85B offers us no real tools to adjust motion according to our needs. It’s only good when the source itself operates at a higher frequency – for example, games at 120 Hz. But when it comes to films or sports, we simply have to accept what the television shows us, because nothing more can be done about it.

While gaming on the console, the television LG UR781 offers several important features that can affect the gaming experience, but it also has some limitations. A positive aspect is the presence of ALLM (Auto Low Latency Mode), which automatically optimises picture settings by switching the television LG UR781 into low latency mode, which is beneficial for gamers. The television also supports proper implementation of HGiG, meaning HDR games look as intended by the developers.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which may result in poorer fluidity of gameplay, particularly in more dynamic games. It also does not support Dolby Vision mode for games, which limits the HDR picture quality in games using this format. The television has a panel with a frequency of 60hz, which means it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant drawback for gamers expecting smoother gameplay at higher resolutions. It also lacks support for G-Sync technology, which limits image synchronisation in games.

However, a positive aspect is the presence of the Game Bar feature, which allows quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

On paper, the Panasonic W85B looks really solid. It has two full HDMI 2.1 ports, support for ALLM, variable refresh rates, Dolby Vision in games, and of course, a high refresh rate of the panel itself. Additionally, it features Panasonic's characteristic game tools bar – a "game bar" that allows you to preview key parameters and quickly change them if needed with a single click. This sounds great, but the problem arises when we turn on HDR. Here, the W85B suffers significantly, as there is practically no HGiG implementation – the television poorly manages brightness, and instead of an accurate picture, we get scenes that are too bright, sometimes even blown out. The solution? The simplest one – turn off HDR in the console settings and leave everything in SDR. And this is where it gets really interesting, as in this scenario, the W85B shows its better side. Low input lag, high fluidity thanks to 120 Hz – all of this makes gaming look phenomenal. Indeed, HDR can be forgone, but if the priority is responsiveness and smooth gameplay, the W85B offers a lot of fun.
