LG UR781 vs Philips OLED809/819

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.

Philips OLED 809 delivers a more than satisfying HDR effect. The television is capable of generating brightness exceeding 900 nits in almost every scene, and sometimes even over 1000. This result allows for a full experience of content with a wide tonal range. The only moment when Philips OLED 809 is unable to generate higher brightness is in a scene from the movie “The Meg,” which features a large amount of bright white across a significant portion of the screen. However, this cannot be regarded as a poor result, as it represents a considerable improvement over its predecessor. Generally speaking, such values for OLED panels produced by LG Display, which do not feature MLA technology, are very, very good. When combined with high coverage of the DCI-P3 colour gamut, they allow for an exceptional HDR experience. The Philips OLED 809 test showed that this television supports popular HDR formats such as Dolby Vision and HDR10+.

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.

The best factory mode in which we conducted all our tests was "Filmmaker", which has become rather standard in televisions from this manufacturer. However, let's check what its characteristics were before we began the calibration process. The first aspect we will examine is white balance, as despite appearing unassuming, it determines whether the image will be free from any kind of tint. The graph clearly shows that both in SDR and HDR materials, there was a dominant presence of two colours: red and green, which resulted in a strong yellow tint that was ubiquitous across the entire image. This is perfectly visible on the "ColourChecker" palette, where all hues shifted towards their warmer counterparts. The second thing we will scrutinise is, in our opinion, the two most important graphs regarding image quality assessment: gamma and the EOTF curve. Both aim to maintain adequate brightness and contrast. The first one serves to describe the brightness level in SDR materials, while the second shows the rate of luminance increase. Analyzing the first one, we can observe that it was extremely lowered compared to the reference value marked by the orange line. This situation resulted primarily in a sharp increase in brightness and a significant reduction in contrast, almost reminiscent of that in OLED televisions. The EOTF curve exhibited greater "moderation" and only slightly brightened the entire image to 50% of the maximum brightness.

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.

Philips, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we will find both 2- and 20-point grey scale adjustments, as well as an advanced CMS (Colour Management System). As you can observe, this has brought about extremely beneficial results and profoundly changed the perceived image. Practically every one of the elements mentioned above has undergone a transformation and has been brought back to its natural state. This is particularly evident on the "ColourChecker" palette, where the measured samples are harmoniously in place. It must be said that the white balance has turned out exceptionally well, allowing us to enjoy a clean image free from any tint in both SDR and HDR materials. The biggest issue of OLED809, namely gamma, has been properly modelled and only shows minor errors here and there, which will not affect the overall picture. The EOTF curve, on the other hand, has been rid of that subtle brightening and now presents itself as reference-level.

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.

Philips OLED 809 did not perform particularly well in the test of tonal transition fluidity. Moving on to the part of the test where we assess the behaviour of the television's algorithms, we will once again check the function responsible for removing posterization. Indeed, such a function exists in the menu and has several available options. As you can see in the picture on the left, although its presence has been confirmed by us, it is not useful. Only at the highest setting does it effectively remove stuttering; however, it blurs the entire image in the process. Therefore, it is completely useless.

It happens more than once or twice that you and we watch lower quality materials. In this case, the quality of the image upscaling algorithms can have a beneficial effect. We must admit that those implemented in OLED 809 work quite efficiently and improve image quality without visible artifacts. You can only notice slight edge fringing; however, it is unlikely to be visible during normal viewing.

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.

The maximum refresh rate we can set on the tested television is 144 Hz. This value can be achieved by connecting it to a really powerful PC. In the case of consoles or television, everything remains the same. For those who require high smoothness of motion or dislike the characteristic stuttering of films recorded at 24 fps, the manufacturer has prepared a fairly extensive motion smoothing system. In the dedicated tab, we will find a slider for “Smoothness” that is responsible for eliminating stutter, and “Motion Blur Reduction,” which helps increase the sharpness of dynamic elements. The function works very well and granularly, meaning that each setting has a real impact on the perception of motion. We also mention that it works at a refresh rate of 120 Hz, as it operates on multiples of film or television materials. With such an extensive set of options, every user will find their golden mean. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

Motion is influenced not only by settings on the television but also by the response time of the panel itself. OLED televisions feature the best response time on the market, which in the case of 809 is about 0.1 ms. There are no IPS/ADS or especially VA panels that come close to the results of organic panels.

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.

The Philips OLED 809 television supports all technologies included in the HDMI 2.1 standard, and during our testing, each one activated without any problems. Therefore, we must state that this television is perfectly suited for all gamers, whether they are using a console or a computer. It is worth mentioning that the manufacturer has opted to implement the HGIG mode, which provides a great alternative to Dolby Vision, which unfortunately in the OLED809 is unplayable due to very high input lag.

A nod to gamers is also the inclusion of a dedicated GameBar, which allows for monitoring current gameplay parameters and quick changes to settings. We will also find a function to enable a crosshair, which will be very useful when shooting with a sniper rifle, but from the so-called hip. Additionally, we can also find a shadow enhancement function for better visibility in shadows and a colour filter for gamers with visual impairments.

In summary, the OLED 809 is a very good and versatile device for gamers. Anyone who purchases this television for gaming does not need to worry about anything, as it is simply made for gaming. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will allow for an even greater immersion in their favourite title. Lastly, we will add that the only downside of the television in game mode is the artificial image sharpening, regardless of the settings, and it cannot be 'softened'.
