LG UR781 vs Philips PUS7009 (VA)

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.

In terms of HDR effect quality, Philips PUS7009 performs very poorly. A brightness level of 250 nits does not allow for an enjoyable HDR experience, and the image resembles more of a standard SDR. There’s no mention of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is definitely insufficient. The lack of full colour coverage means that the colours are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects of this model that could be praised in the context of HDR.

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.

The television was tested in movie mode, which - despite its name - does not provide correct image display. The white balance in both 4K HDR and HD/SDR content shows drops in the red color, making the image cooler and the colors lose their natural warmth. The gamma brightness characteristic and EOTF curve confirm that the television struggles to maintain appropriate brightness - it excessively boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where everything looks as if a milky filter has been applied. Additionally, the limited coverage of a wide color gamut does not contribute positively to quality - color checker tests indicate significant color fluctuations, making it difficult to achieve faithful image reproduction.

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.

After calibration, the image significantly improved, especially in terms of white balance, which is now more stable, and the hues have gained a natural quality, eliminating the previous impression of an overly cool image. The calibration brought noticeable benefits in tonal quality – shadows and midtones are now more realistic, and the overall appearance seems more harmonious. Unfortunately, hardware limitations still affect image quality. Brightness characteristics remain problematic, despite our efforts, and due to poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration improved some aspects, the television still does not provide full satisfaction.

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.

When it comes to tonal transitions in low-quality material, the function called "Distortion Reduction" (setting “minimum”) effectively improves the gradation, eliminating unsightly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur grain or good quality material, it can introduce unwanted effects and blur elements that should remain clear with a poorer signal.

In terms of image scaling, Philips PUS7009 performs reasonably well. A major advantage is the lack of cropped edges of the image, meaning no overscan, which allows for displaying the full frame without losses. The image is noticeably enhanced, making characters and backgrounds, such as the model or branches in the background, appear quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desired details in the distance, the results are good enough to satisfy most users.

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.

Philips PUS7009 does not have motion smoothing features, which means there's no option to adjust the picture for a choppier or smoother, theatrical effect. Such features could positively affect the viewing of dynamic scenes. In terms of motion blur, this model is equipped with a 60 Hz VA panel, which delivers slightly worse results than the IPS panel variant. The VA panel introduces minimally greater motion blur, although the differences are not significant and should not pose a problem for most viewers.

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.

In terms of compatibility with consoles, Philips PUS7009 is likely to satisfy casual gamers. Although equipped with HDMI 2.0, it offers features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the TV to low latency mode, which speeds up responses during gaming, and VRR adjusts the refresh rate to minimise screen tearing. The Game Bar provides quick access to game settings and monitors key parameters, although visually it falls short compared to competing solutions. However, more demanding gamers may feel underwhelmed. Philips PUS7009 does not support advanced HDR formats in games, and the 60 Hz panel limits its ability to display smooth and detailed images in dynamic scenes, which may not satisfy fans of fast-paced action games.
