Philips PUS7009 (IPS) vs LG UT8100 (IPS)

In terms of HDR effect quality, PUS7009 (IPS) performs very poorly. A brightness level of 250 nits does not allow for enjoyment of HDR effects, and the image resembles a more standard SDR. There is no talk of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is decidedly 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 for which this model could be praised in the context of HDR.

Unfortunately, the LG UT8100 television does not meet expectations in the HDR effect category. With a peak brightness of only 300 nits on the luminance chart, it is well below the required value to fully enjoy the HDR effects. In practice, the image resembles SDR quality more than true HDR, which is particularly evident in demanding high-contrast scenes. The coverage of the DCI-P3 colour palette is only 82%, further limiting the ability to present vibrant and rich colours. Instead of impressive visual experiences, we receive a muted and lacklustre image. For those looking for a television to fully utilise HDR content, the LG UT8100 model proves to be quite disappointing.

The television was tested in film mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content is characterised by drops in red, causing the image to appear cooler and the colours to lose their natural warmth. The gamma brightness characteristics and the EOTF curve confirm that the television has issues maintaining appropriate brightness – it heavily boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the entire image appears as if it has a milky filter applied. Additionally, the limited coverage of a wide colour gamut also does not favour quality – colour checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

The Filmmaker Mode in LG UT8100, although theoretically the best for watching films, has significant flaws. The biggest problem is the white balance – drops in blue colour cause a noticeable yellowing of the image, evident in both HD and 4K content. These errors are confirmed by the measurement results in the Colour Checker test, which indicate significant deviations in colour reproduction.

Regarding brightness characteristics, both HD and 4K content feature a substantial tonal boost. The gamma curve in both cases remains significantly below the reference value of 2.4, leading to excessive brightening of darker elements of the image. A similar issue is noticeable in the EOTF curve – for 4K content, the television struggles with properly managing brightness, which results in problems with screen brightness. This means that the factory settings of this model require significant adjustments to achieve better image quality.

After calibration, the picture has significantly improved, especially in terms of white balance, which is now more stable, and the shades have taken on a natural quality, eliminating the previous impression of a picture that was too cool. Calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall effect seems more harmonious. Unfortunately, hardware limitations still affect the quality of the image. The brightness characteristics remain problematic, despite our efforts, and due to the poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration has improved some aspects, the television still does not allow for complete satisfaction.

After calibrating the Filmmaker Mode, the gamma has been aligned to practically ideal, reference values, which has significantly improved the overall tonal characteristics of HD content. 4K HDR content also looks better, although certain issues are still visible at the extreme ends of the graph, where the curve deviates from perfection. The EOTF curve performs worse, as the television has difficulty maintaining appropriate brightness values. As a result, the image in some scenes may be overly bright or slightly dimmed, which is due to the very design of the device. Nevertheless, the calibration has brought considerable improvement, especially for HD content, where tonal balance and colour reproduction are now at a much higher level.

When it comes to tonal transitions in low-quality material, a feature named "Distortion Reduction" (set to "minimum") effectively improves gradation, eliminating ugly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur the grain or good-quality material, it can introduce undesirable effects and blur elements that should remain sharp when the signal is poorer.

In terms of image scaling, Philips PUS7009 performs reasonably well. A significant advantage is the absence of cropped image edges, meaning no overscan, which allows for the display of the full frame without loss. 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 desirable details in the distance, the results are good enough to satisfy most users.

The fluidity of tonal transitions is also correct, although the effect depends on the settings. The update has improved the performance of the smooth gradation function, smoothing transitions better than before, but it has introduced minor issues with detail loss, e.g. on textures.

The image scaling on LG UT8100 performs very well. The image looks decent, without significant issues with edge aliasing. Details are preserved at a satisfactory level, which makes lower resolution materials look truly solid on this television. This allows users to enjoy watching older content without noticeable flaws in quality.

Philips PUS7009 does not have any motion smoothing features for films, which means we cannot choose whether the picture should be more choppy or more cinematic. These features could improve more dynamic scenes. As for motion blur, despite using a 60Hz IPS panel, the situation looks quite good. The response time between pixels is better than in versions with a VA panel, which keeps motion blur at an acceptable level and does not significantly affect the comfort of watching dynamic scenes.

LG UT8100, equipped with a 60 Hz panel, is particularly suited for those watching films. The television offers the TruMotion system with de-judder effect adjustment, allowing you to customise the smoothness of the image – from more choppy to exceptionally smooth, resembling a soap opera effect, depending on the user's preferences.

In terms of compatibility with consoles, Philips PUS7009 is suitable for casual gamers. Despite the use of HDMI 2.0, the television offers access to features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the television to low latency mode, allowing for quicker response times during gameplay, while VRR dynamically adjusts the refresh rate to reduce the tearing effect. Game Bar is a tool that provides quick access to game settings and real-time monitoring of parameters - although we believe it appears the weakest compared to competing Game Bars.

Unfortunately, more demanding gamers may be disappointed. The Philips PUS7009 does not support advanced HDR formats in games or high refresh rates, due to the use of a 60 Hz panel. The lack of support for these features limits the television's ability to deliver smooth and fully detailed experiences during dynamic gameplay.

LG UT8100 offers basic features for gamers, such as ALLM and Game Bar, which makes access to settings easier. The television also supports HGiG, which improves image quality in HDR games. Unfortunately, the lack of support for Dolby Vision and VRR limits the capabilities of the device, as does the 60 Hz panel, which excludes support for 120 Hz resolution. This model is more suitable for less demanding gaming applications.
