Philips PML9009 / 9019 / 9059 vs LG 55 B4

Philips PML9009 doesn't really operate at the highest values in HDR materials. Most effects with brightness around 550 nits won't leave us thrilled with the lighting effects, although they are quite stable, which is a plus, and a considerable difference can be felt between SDR materials. It's worth noting that we can achieve a good result only in one scenario, that is in the film "Gemini," where the flashlight as the sole light source can really shine. Why in this scene? The answer is quite simple. The scene itself doesn't have a large amount of black, and the flashlight isn't as large an object as the sun in the first and last scenes. Overall, the brightness measurement results in HDR materials aren't a solid basis for recommending this television for viewing productions that use a wide color gamut. However, it's worth mentioning that this model can cover it in a not too bad 93% degree in the case of the DCI-P3 palette.

The brightness results in HDR materials LG B4 are very good. It is true that none of them exceed 1000 nits, although the luminance stability is excellent and looks practically the same in every scenario. The only moment where the tested television performs worse is the last scene, although this should not come as a surprise. Large frames filled with a lot of white have always been, and will likely continue to be, somewhat of a weakness for OLED televisions. However, the combination of perfect contrast, black levels, and brightness in the LG B4 allows for a full spectrum of the HDR effect. Additionally, the incredibly high coverage of the DCI-P3 colour gamut, which reached 99%, deserves recognition. As a result, colours look incredibly vibrant and stunning.

The best factory mode used during our tests was "Filmmaker". Here, we will examine both SDR and HDR content. The key differentiator is primarily the EOTF curve in the wide colour gamut materials and gamma in those recorded "the old way". Starting with SDR films and series and the most basic thing we can observe, which is white balance, we see a significant red colour dominance. This led to a yellow tint across the whole image, causing unnaturally looking faces and yellowed whites. This issue is also clearly visible on the "ColourChecker" palette, where all colours have shifted towards their warmer counterparts. Looking at an even more significant graph, the gamma responsible for the contrast of the image, we see considerable errors beginning right from the start. From the left, the value we measured, indicated by a combined ellipsis, clearly spiked upwards, causing complete merging of details in the darkest scenes. This state of affairs persisted up to 10% brightness on the screen, after which it dove below the reference orange line, leading to a deterioration in contrast, which, as we know, Philips PML9009 is already lacking. In HDR materials, white balance issues were very similar to those in SDR content. The discrepancy appears when checking the EOTF curve, which governs the rate of brightness increase and severely limited it, resulting in an unnaturally dark image. As for the colours themselves, there were more reasons for concern here, as the television's low luminance caused a huge disparity between the actual state and the correct one, which is perfectly visible on the error graph, often exceeding the scale.

The best factory mode prepared by the manufacturer is "Filmmaker," and we used it throughout the entire testing procedure. We must admit that the unit we received straight out of the box had quite decent colour reproduction. The biggest issue in both SDR and HDR content turned out to be white balance. In the former, there was a strong dominance of red, resulting in a noticeable yellow tint in the displayed image, particularly evident on skin tones and whites. In high-quality materials, this colour was also pronounced, but due to a lack of blue, there were also signs of green visible. Besides these shortcomings, we also encountered issues with greyscale and the colours themselves.

Philips PML9009, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we find 2-point and 20-point greyscale adjustments, as well as an advanced CMS (Color Management System). The differences resulting from calibration are evident, and even someone who doesn't pay attention to image quality (although there probably aren't many like that here) will notice the positive difference. Both SDR and HDR materials have undergone quite a transformation. The former and the latter have primarily shed the ugly yellow tint resulting from the red colour dominance in white balance. As for the SDR materials and gamma, although it is not perfectly modelled and still loses dark details, the rest of it is at more than a decent level, and minor errors will not be noticeable. The colours themselves look far better, and with low deltaE errors, they are almost reference-quality. On the other hand, HDR materials, due to the unit's low luminance, have not been optimised as we would have liked. Although the white balance has been largely normalised, a slight blue tint can still be observed here and there. Fortunately, the EOTF curve turned out to be much more accessible, allowing for practically perfect geometry. Unfortunately, due to the screen's too low brightness, the colour errors remain quite high.

LG B4 has been providing very advanced calibration tools in its TVs for years. We can even say that as the only manufacturer on the market, it allows for such deep intervention in image adjustment. Thanks to these, we were able to calibrate the device so well. The evidence of this is the extremely low deltaE errors, which can be said to stand at a reference level. Both SDR and HDR materials now look exactly as the film director intended. It is no coincidence that TVs of this brand are most often used as preview screens for various graphic or post-production studios.

Judging by how PML9009 Philips handled tonal transitions, the image scaling test should perform just as well. This time, we are checking the TV’s algorithms responsible for enhancing the quality of images that were recorded in lower quality. Such images can be found, for example, in various TV shows or older films. In this regard, Philips PML9009 performs quite mediocrely and drastically blurs the image. This is particularly noticeable on fine branches or the model's hair.

Let’s revisit the issue of tonal transitions, which performed remarkably well. Within the unit, we will find several levels of smoothing. Even the lowest one can effectively eliminate any jerky tonal transitions and will be suitable for the vast majority of materials. More importantly, none of the settings for this function soften the effect of film grain, which is extremely important in terms of alignment with the director's vision. However, we would like to point out that sometimes it may turn out that fine details are blurred.

In this paragraph, we will take another look at the tonal transition smoothing feature, but we will also check how the TV handles lower quality material. As we have managed to check, the setting responsible for smooth gradation works quite effectively, although it has its weaker moments. While the feature works well with SDR content, it becomes less useful with HDR content. Even at the lowest of options, it blurs essential details, so we advise against using it.

The image scaling on LG B4 is rated fairly moderately positively. Although there is no edge splitting, the image itself is naturally "soft". We can change this by adjusting the sharpness slider.

Philips PML9009 has been equipped with a panel that has a native refresh rate of 120 Hz. This is the essential minimum for watching all kinds of sports and is recommended for comfortable gaming in favourite titles on consoles or PCs. The manufacturer, for those who dislike the characteristic judder of footage recorded at 24 fps or those requiring a high degree of motion smoothness, such as when watching football matches, has prepared an effective system for improving the sharpness of moving images. In the dedicated tab, we will find a "Smoothness" slider responsible for eliminating judder and a "Motion Blur Reduction" setting that helps to increase the sharpness of dynamic elements. The function works very well and granularly, meaning each setting has a real impact on motion perception. With such a set, every user will find their sweet spot. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

A matter directly related to motion is the response time of the pixels in the panel itself. The best in this regard are of course OLED panels, followed by units based on IPS and ADS screens, and lastly VA. Despite the generally good quality of the systems responsible for smoothening the image, the use of a VA panel carries consequences in the form of black smear behind fast-moving objects. Although in the tested television this should not occur frequently, it will be noticeable here and there.

The maximum refresh rate we can set on the LG B4 is 120 Hz. This is the absolute minimum for those who require high image smoothness. The manufacturer has implemented a multi-level motion smoother called "TruMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and stuttering (De-Judder). Both sliders can be set in the range from 0 to 10, with each level affecting the degree of smoothness, so everyone can find their sweet spot.

The LG OLED B4 panel features an average response time of 0.1 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable for LCD TVs, which have response times of even several milliseconds. This can be clearly seen in images from the "UFO Test", showing no trace of blur trailing behind the object.

Philips PML9009, equipped with HDMI 2.1 connections with full bandwidth, supports all functions dedicated to gamers. The most basic ones, such as VRR and ALLM, are a given, but G-Sync, FreeSync, or playing in HDR Dolby Vision with low input lag are not. These features activate without any problems, and during the tests conducted, they presented no obstacles. Such preparation of the television is certainly its strong point, and it can be said that it is a unit dedicated to gamers. For more advanced users, we also mention that the PML9009 is equipped with the HGIG mode, which will be particularly felt by gamers, as there are still relatively few games that support Dolby Vision. This mode primarily allows for the adjustment of HDR effects to the capabilities of the television on a special board, to prevent dimming and burning of the image.

The television additionally implements a special menu - GameBar. This allows for editing unit settings "on the fly," meaning without having to exit the game. In it, we will also find functions such as activating a crosshair or black level correction for better visibility of opponents in shadows.

In a brief summary of this paragraph, the Philips PML9009 is a unit that will undoubtedly attract gamers' attention. Thanks to its versatility, it will allow for playing any title in the highest quality without compromises. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or gameplay in HDR Dolby Vision will provide an even greater immersion in the favourite title.

The LG B4 television is equipped with four full-fledged HDMI 2.1 ports with a full bandwidth of 48Gbps. All functions corresponding to this standard activated without any issues, and throughout the entire testing procedure, they caused no problems. The combination of such extensive functionality and low input lags leads us to say that the tested television is truly designed for gaming. This is not surprising, considering that the manufacturer has always placed great emphasis on this. Therefore, we can enjoy both a properly implemented HGIG mode and gameplay in Dolby Vision with low latency. Such a tandem will surely attract the attention of all passionate gamers for whom quality is the most important.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also enables image adjustments for individuals with visual impairments, which is an extremely nice touch. Another important piece of information is that when the VRR technology is turned on, we will not experience a drop in contrast. This is, of course, due to the construction of the panel and the lack of conventional backlighting. However, it is normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and the television.

In summary: The LG B4, like all OLEDs from the manufacturer equipped with 120Hz panels and HDMI 2.1 ports, creates a harmonious whole with the console. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, the B4 will be the ideal choice.
