LG UT8100 (IPS) vs Philips OLED910

The LG UT8100 television unfortunately does not meet expectations in the HDR effect category. The peak brightness of only 300 nits on the luminance graph is significantly below the required value to fully enjoy 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 color palette is only 82%, which further limits the ability to present vibrant and rich colors. Instead of impressive visual experiences, we get a muted and washed-out image. For those looking for a television to fully utilize HDR content, the LG UT8100 model proves to be highly disappointing.

OLED910 is simply an absurdly bright television for an OLED. All thanks to the new panel from LG Display, the Tandem RGB OLED, which Philips has dubbed its "META OLED." It is this panel that allows for over 2000 nits of brightness in films, which was previously completely unattainable in OLEDs. The way the television handles full-screen scenes drenched in bright light is also commendable. Usually, in OLEDs, brightness drops significantly, but here it remains at an excellent level - around 1400 nits. These are almost reference values, and combined with the great color gamut reproduction at 99% DCI P3 and 82% BT.2020, it gives us an HDR effect that can confidently be called one of the best in the world.

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

As for brightness characteristics, both HD and 4K content feature a high tonal boost. The gamma curve in both cases remains well below the reference value of 2.4, leading to excessive brightening of darker elements in the image. A similar problem is evident in the EOTF curve – in the case of 4K content, the TV struggles with proper brightness management, resulting in issues with screen brightness. This means that the factory settings of this model require significant adjustment to achieve better image quality.

Unfortunately, when it comes to color reproduction right out of the box, the Filmmaker mode on the OLED910 performs poorly. The television overly emphasizes the color blue, and at times it almost looks like a store mode. It gives the impression that the manufacturer hasn't quite calibrated the device properly. The result is that colors look unnatural, and the overall effect resembles a somewhat exaggerated display from a market showcase. HDR content looks much better, where aside from a slight loss of detail in blacks, it's hard to find fault with anything. The problem is that in everyday viewing, it is the SDR materials that matter the most – and on the OLED910, they simply look bad and are far from what we would expect from a television of this class.

After calibrating the Filmmaker Mode, the gamma has been aligned to practically ideal, reference values, which significantly improved the overall tonal characteristics in HD content. 4K HDR content also looks better, although some issues are still visible at the end of the graph, where the curve deviates from the ideal. The EOTF curve performs worse, as the television struggles to maintain appropriate brightness values. As a result, the image in some scenes may be overly bright or slightly dimmed, which stems from the device's design. Nevertheless, the calibration has brought significant improvements, especially in the case of HD content, where tonal balance and color reproduction are now at a much higher level.

Fortunately, it quickly turned out that it was not the panel that was responsible for the issues, but rather the way Philips had calibrated the OLED910 from the factory. After calibration, the television displayed its full potential, and only then could we see what the new panels produced by LG Display were truly capable of. We primarily corrected the white balance and brightness characteristics, which allowed us to tame the excessive blue and give the image a natural look. The final effect can be described as excellent. Errors on the Color Checker palette rarely exceeded a value of 3, which in practice means an image close to perfection and colors presented in accordance with the creators' intentions. In SDR content, the effect was remarkable, and in HDR, the improvement was even more noticeable – gradients became cleaner, and colors fuller and more believable. After calibration, the OLED910 transformed from a disappointing television into equipment that can easily be called reference-level in terms of color reproduction.

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

Image scaling on LG UT8100 performs very well. The image presents itself decently, without major issues with edge aliasing. Details are preserved at a satisfactory level, which makes lower-resolution materials look really solid on this TV. As a result, users can enjoy watching older content without obvious quality flaws.

The previously visible color artifacts can largely be eliminated thanks to a feature called "distortion reduction." Similar to the OLED820, it's best to set it to a medium level, as it then produces quite decent results – smoothing out unwanted tonal transitions while not taking away too many details from the image. Although there may be times when the effect is a bit too aggressive, it can generally be considered a useful feature for everyday viewing.

As for image scaling, the OLED910 performs really well. The test material with the model had a characteristic soft look typical of Philips – at times even too soft – but the sharpness slider can be adjusted at any moment to tailor the image to personal preferences. It's also worth noting that the TV has no issues with overscan, which still occurs in some competing models. It's a small detail, but it's pleasing because it means that all content, even the oldest, is displayed as it should be.

LG UT8100, equipped with a 60 Hz display, will be especially suitable for people watching movies. The television offers the TruMotion system with de-judder effect adjustment, allowing users to customize the fluidity of the image – from more choppy to exceptionally smooth, reminiscent of a soap opera effect, depending on user preferences.

The OLED910 is a television with a refresh rate of 144 Hz. It's a bit disappointing that Philips didn't choose 165 Hz, because we know that the panel used in it is capable of that. On the other hand, such a bonus would mainly benefit PC gamers, as in everyday use, the most important refresh rate is 120 Hz, which is fully sufficient. Combined with the advantages of an OLED panel – lightning-fast pixel response time and no motion blur, the image is impeccably sharp and fast, even in dynamic action scenes. Kudos also goes to Philips' traditional motion smoother called "Motion Style." We can easily adjust it to our preferences: the "Smoothness" slider is for movies and allows you to choose between a more "frame-like," cinematic character and a smooth, theatrical image. Meanwhile, the "Blur Reduction" slider is for sports; it is worth setting it to the maximum value here to ensure that the image is clear and distinct during very fast shots.

LG UT8100 offers basic features for gamers, such as ALLM and Game Bar, which makes access to settings easier. The TV 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 will be more suitable for less demanding gaming applications.

The OLED910 is excellent for gaming. It supports 144 Hz, so if someone has a powerful PC, they can easily take advantage of that potential. On consoles, 120 Hz is the most important, and everything works perfectly here. There is VRR, an automatic game mode, and even Dolby Vision in games along with an HGiG mode, so we actually get a full package of gaming features. Philips also added a Game Bar, which is a quick menu that shows basic information and allows you to enable a few useful things. It may not look as modern as the competition, but it works and serves its purpose. The only downside is the number of HDMI 2.1 ports. There are only two, which can be somewhat disappointing for a TV in this class. If someone is connecting two consoles and something additional to eARC - like a soundbar (which doesn't make much sense in this model, but we'll discuss that in the sound section), they'll need to figure things out a bit more. Other than that, the OLED910 has everything we expect from a gaming TV.
