LG OLED G4 vs Panasonic Z95B

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are more engaging than ever before.

The HDR effect quality in the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, named Primary RGB Tandem OLED by the manufacturer, the television can achieve over 2000 nits of brightness in movie scenes. The effect is impressive and can amaze with its intensity of light, giving a sense of contact with the screen that goes beyond previous experiences. Similar feelings were only experienced during tests of the LG G5, Samsung S95F, or Philips OLED910. Of course, there are moments when the device's algorithms decide to limit luminance – this especially applies to full-screen bright sequences, such as the ending credits in the movie The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an extremely impressive result. Thus, it can be said that HDR in this model has been brought to a masterful form. A significant step forward is also visible in the reproduction of the colour palette. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of gamut coverage, but the gap between these solutions has significantly decreased. When watching films, the differences are subtle enough that under normal conditions it's hard to notice them, and the colours remain vibrant and saturated.

The best factory mode in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

The factory colour reproduction in Filmmaker mode, my dear friends, is a true phenomenon in the case of the Panasonic Z95B. I'm talking about our test sample, but the results were so good that it's hard to believe. The only detail that one could nitpick is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image like we have never seen in factory mode. Colour palette tests, Color Checker – everything indicated values below Delta 2. This is a much lower result than the threshold of human eye perception, which means, to put it simply, that the viewer has no chance of noticing serious deviations. It looks as if Panasonic actually calibrated this model at the factory stage. Of course, we cannot exclude the possibility that we got an exceptionally well-set specimen, but the result still makes a stunning impression. We are very strict when it comes to assessing factory calibration, and here our jaws simply dropped.

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

The colour reproduction after calibration on the Z95B is a topic that’s hard to elaborate on, as there wasn’t much to do here. A slight adjustment of the white balance was enough to eliminate the lack of blue, and at that moment, the picture jumped to an almost reference level. It must be said that we haven’t had such a small range of adjustments in a long time. If any of you are particularly perceptive, you might notice minimal deviations in the EOTF curve, but this is more related to the functioning of the dynamic tone mapping feature we mentioned earlier. In reality, this isn’t a flaw, but a characteristic of this solution, which intentionally alters the brightness profile depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great right out of the box, and after calibration, it reaches a level where we really struggle to find anything to improve.

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

Let's start with what works well. The upscaling in the Z95B is at a very high level – the image in lower resolutions is clear and sharp, and the only minor shortcomings are slight banding in some areas of the picture. It's also important that the television doesn't crop the material in any way and maintains its proportions, which is not always an obvious fact even in 2025.

The situation looks worse when it comes to digital processing. Features like "gradation smoothing" or "block noise reduction" essentially do not work – the tested material looked identical regardless of the settings. We might as well say that this feature simply doesn't exist. It's a bit disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence improving image quality. Meanwhile, in such a basic matter, the television does not deliver a real effect and it looks weaker than one would expect from top-tier equipment.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range from 0 to 10, with each increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

The OLED panel with very high refresh rates already provides an incredibly sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It's also very important that the television is equipped with the proprietary motion smoothing system 'Intelligent Frame Creation'. Among the available sliders, the most crucial one turns out to be the one called 'film smoothness', as it allows for adjusting the motion to personal preferences with 24-frame content, meaning films – from a more 'choppy' appearance to a smooth, almost theatrical effect. It's a bit disappointing that Panasonic didn't opt to push the latest OLED panel to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know that the panel is technically capable of it. On the other hand, it mainly benefits PC gamers, so in everyday viewing, it's not a significant drawback as we are limited to 120Hz.

The LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of gaming and online competitions. With full HDMI 2.1 ports with a complete bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will bring a lot of joy.

The Panasonic Z95B is fully equipped for gaming. Two HDMI 2.1 ports with a full bandwidth of 48 Gb/s guarantee support for everything you can expect from a modern screen. It features VRR frame syncing, an automatic game mode (ALLM), and full compatibility with HDR formats used in gaming. The TV supports both Dolby Vision for Xbox and the popular HGiG, which in this case has been implemented correctly, so it actually works as it should.

Although the brand is mainly associated with home cinema and equipment for filmmakers, there’s also space for gamer conveniences here. Onboard is the Game Bar (or rather Game Circles) – it looks a bit unusual visually, but it does its job and allows you to quickly check the most important image parameters. The only thing missing for complete satisfaction is actually having four HDMI 2.1 ports instead of two. It’s a minor detail, but with a TV of this class, one could expect a full set.
