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 comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look 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 handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

Unfortunately, we don't have good news here. The Panasonic W85B is quite a dark television – its peak brightness doesn't exceed 300 nits, making it hard to talk about any real HDR effect. In practice, this means that scenes which can 'shine' and impress on other screens simply look like regular SDR with a slight colour boost here. Our measurements and film tests confirmed this – regardless of the content, the W85B won't draw anything more from HDR. So if someone is looking for a television specifically for HDR, it's better to look at other models. On a positive note, the W85B does quite well in terms of colours. It's a QLED television, so its colour gamut coverage is wide, and most films and series look natural, without a noticeable 'faded' effect. The colours are saturated, so in everyday viewing, there's no feeling that something is seriously off.

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

Testing the Panasonic W85B, we obviously started with the Filmmaker mode, as it's the gold standard for watching content "the way the director intended." The problem is that this TV 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 looked too warm because of this, and in some scenes, it was almost "on fire." Added to this is the issue of brightness management. When we looked at the gamma and EOTF charts, it was clear as day that in most scenes, the TV brightens the image more than it should. The effect was easy to predict. Details can get lost, leading to flattening and clipping across the entire screen. We obviously know how to fix this, but to be fair, it does require a lot of calibration work. Out of the box, the W85B doesn't produce an image close to reference quality – it's more of a TV that, without professional adjustments, will always interpret colours and brightness a bit "in its own way." Unfortunately, this is to the detriment of the viewer.

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

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach 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 HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

Fortunately, calibration made a significant difference for the Panasonic W85B, especially for SDR content. Here, the improvement was quite evident – we managed to even out the white balance and reasonably tame the TV's tendency to overly brighten the entire image. The picture became more coherent and the colours gained the naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has noticeable issues with green saturation, but overall, we rate the post-calibration effect in SDR quite positively. The situation with HDR is a bit different. Here too, we managed to reduce the tendency to warm up the entire scene, so the image performed definitely better than in the factory settings. However, there is still the same problem we mentioned earlier – the TV interprets the image too strongly "in its own way" and brightens the whole screen. And the lack of local dimming only exacerbates this effect. In summary, briefly, in SDR content, the W85B performs really well after calibration and is perfectly suitable for everyday viewing. However, in HDR, even after adjustments, it is still difficult to unambiguously recommend it for more serious viewing.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or clear outlines. However, the situation is worse with lower resolution materials. This is where the TV has the biggest problem with "beautifying" the image. The lack of any menu option to improve gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with colour blending.

Fortunately, upscaling, or enhancing 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 TV handles this better than one might expect from such an inexpensive setup. This is thanks to the HCX processor, which Panasonic has been developing for years, and it shows that even in the lower series, it can do a good job.

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on 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 like it should handle smooth motion really well. The problem starts when we delve 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’s a lack of BFI, or black frame insertion, which in many TVs helps sharpen motion. And suddenly, it turns out that despite the strong panel, the W85B doesn’t give us any real tools to adjust that motion 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 movies or sports, we just have to accept what the TV shows us because there’s nothing more that can be done about it.

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

On the positive side, the presence of a Game Bar feature allows for 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 for the panel itself. Additionally, there's the characteristic Panasonic game bar, which allows you to view key parameters with a single click and quickly change them if needed. It sounds great, but the problem arises when we enable HDR. Here, the W85B really struggles because the implementation of HGiG is practically nonexistent – the TV poorly manages brightness, and instead of faithful images, we get scenes that are too bright, sometimes even blown out. The solution? The simplest one – turn off HDR in the console settings and keep everything in SDR. And here it gets really interesting, because in this scenario, the W85B shows its better side. Low input lag, high smoothness thanks to 120 Hz – all of this makes gaming look phenomenal. Yes, HDR can be skipped, but if responsiveness and smooth gameplay are the priorities, the W85B provides plenty of fun.
