Compare: LG OLED C4 vs Panasonic Z95A

LG C4 is a television that, in its price range, will likely have no competition for many users. Thanks to its extensive capabilities, it will appeal to those looking for a television not only for films and series but also for gaming. The advanced WebOS system and a remote control that functions like a mouse will certainly be a significant convenience in everyday use, making it likely that we will stick with this brand for much longer. The OLED panel implemented by the manufacturer, resulting from over 10 years of history, shows that this brand has not yet said its last word. The brightness results in HDR materials are very solid and can deliver an incredibly dynamic and deep image. It is worth mentioning the excellently implemented dynamic tone mapping feature, which makes HDR10 content look almost as good as Dolby Vision. And when it comes to fidelity to artistic vision, one cannot overlook how calibratable LG televisions are, allowing considerable freedom for calibrators and classic calibration for home users, as well as 3D LUT for professionals. However, if we are looking for a gaming television, then the LG C4, like most of the manufacturer’s OLED televisions, will be an ideal choice. With the implementation of HDMI 2.1 ports and the full utilisation of their potential, we can enjoy incredibly smooth gameplay with all the benefits, such as VRR, ALLM, FreeSync, and G-Sync. Of course, the panel, with a maximum refresh rate of 144 Hz and an advanced motion smoother, will also provide a very smooth and sharp image during the broadcast of various sporting events. It is hard not to give a high rating to LG OLED C4, as a television in a similar price range with such advanced features is difficult to find among the competition.

During the Panasonic Z95A tests, we felt as though we were holding a television that deserves to be called one of the best on the market. When it comes to picture quality, it is exceptional! The OLED with infinite contrast, perfect blacks, and incredible brightness makes watching films a pure pleasure. The micro lens array (MLA) truly made a difference. Thanks to it, the picture gained not only in brightness, reaching a spectacular 1500 nits in HDR content but also improved viewing angles - which are already quite good in regular WOLED panels. As a result, every scene looked so realistic that we felt as if we were part of it. We also checked how it performs in various lighting conditions – it impressed without exception in both dark and bright rooms. We couldn't complain about the sound either. The built-in soundbar with Dolby Atmos surprised us with its spaciousness and dynamics, which is usually lacking in speakers integrated with televisions. This is really solid support for cinematic experiences. The Panasonic Z95A does not disappoint gamers either. We tried out its gaming features – support for ALLM, VRR, a 144 Hz panel, and playing in Dolby Vision at 120 Hz are things that every avid gamer will appreciate. Additionally, there are practical extras such as the ability to record to an external disk and a PiP function, which enhance everyday use of the television. Of course, we also noticed some downsides. The Fire TV operating system from Amazon, although better than in older models, still has its flaws. The absence of certain popular apps, such as Player.pl or TVP VOD, and poorly executed translations in the interface can be frustrating at times, especially in a television in this price range. Panasonic Z95A is a television with a capital "P" like premium. It impresses with its image quality, sound, and functionality. However, its high price may deter some, especially when there are devices on the market offering similar capabilities at a much lower price. However, if the budget is not an issue, Z95A is a television that delivers cinematic experiences at absolutely the highest level.

LG OLED C4, as the name suggests, uses an organic panel of its own production. This series definitely ranks among the most recognisable on the market. Over 10 years of experience in the construction of self-emitting panels has allowed for the refinement of each subsequent design, with the models from the 2024 vintage being the epitome of this. Of course, the use of this type of screen enables the achievement of impeccable contrast and blacks, allowing for immersion in the world created by the director. This is made possible by the OLED panel, characterised by the absence of conventional backlighting, with current passing through organic pixels instead. This allows for super-accurate control of the image, thereby eliminating issues such as the dimming of delicate fine details or the halo/blooming effect. Looking at both of our test scenes, we can observe two things: perfect separation of lights and a whole plethora of details in the film "Sicario 2".

The contrast and black levels in the Panasonic Z95A television are at a level that captures the attention of even the most discerning viewers. The Z95A, as befits an OLED, delivers remarkable results in this area. In every tested scene, the contrast is practically infinite, translating into excellent image quality in real-world conditions. During the screening of the film Oblivion, one can see how light sources, such as lamps, fall on the actor, creating an incredibly realistic effect. The Z95A Panasonic reproduces these black details with impressive precision, making even subtle differences in brightness and lighting stand out clearly. As a result, viewers experience a sense of depth and naturalness in the image that is hard to find in LED televisions, which often offer various types of compromises.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, allowing for a very realistic image. Of course, none of them surpasses the magical thousand, yet the combination of such results and unlimited contrast and black effectively boosts the outcome optically. The last of the scenes, featuring a full-screen burst of sunlight, is actually less bright than the others, although it still represents a commendable level. It is also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will allow for achieving extremely vivid colours.

Panasonic Z95A showcases class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly renders details and intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good image quality. Additionally, the television offers excellent coverage of wide colour palettes – as much as 98.6% for DCI-P3 and 74.5% for BT.2020. Thanks to this, colours are not only vivid but also deeply saturated, allowing for a full appreciation of the richness of details, especially in HDR scenes. Such coverage makes the hues look more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Because of this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

The best factory mode implemented in the tested television was "Filmmaker". It was this mode that we used during all tests. This mode proved to be quite good in terms of colour reproduction; however, other shortcomings effectively detracted from the enjoyment of viewing. Starting with the most basic aspect, the white balance, it was easy to notice that it was marked by a dominance of red, which overall changed the characteristics of the image. We could thus see a strong yellowing of the whites and a shift of all colours towards warmer shades. The gamma, which is a curve just as important, if not more so, was quite significantly lowered, resulting in a considerable drop in contrast, except at the beginning of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Taking a closer look at films with a wide dynamic range, we can observe exactly the same phenomenon of yellowing of the white balance as in films with a standard colour palette. The EOTF curve, which replaces our gamma curve, is practically perfect and cannot be faulted.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. It offers quite a good image reproduction, but it is not free from certain issues that require improvement. Firstly, the white balance, for both 4K and HD content, tends to have a dominance of red and blue hues. This causes a slight pinkish tint to the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this issue well. The Colour Checker test also confirms these discrepancies, showing slight shifts in the dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor problems when brightening small details. A greater challenge is posed by the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully utilise the television's potential.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We therefore used them to model the image in the way that the director intended. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates that this is how a film should look. It is worth looking at the colour errors on the "ColorChecker" palette here, where practically none of them exceeds "1", apart from two samples.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect picture. The television provides immense adjustment capabilities, which we have fully utilised. The white balance after calibration is positively perfect, and errors in SDR content at the level of 0.5 place it in an absolutely reference standard. The same is true for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and enthusiasts of cinematic picture quality. Significant changes have also occurred in the brightness characteristic – the EOTF curve has been flattened, eliminating previous issues with excessive brightness. And a small gamma error has been reduced.

Before calibration, the picture was decent, but now it's an entirely different league. It's a real feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of colour reproduction.

The fluidity of tonal transitions in LG televisions has always been a fairly sensitive issue, as the manufacturer, despite impeccable performance in other areas, has almost always struggled to get this right. The results of the assessment of the fluidity of tonal transitions in the tested television were quite good, and the problems are mainly visible in darker scenes, such as the last two scenes. Interestingly, this is a result that is definitely better than the highest model from the manufacturer, namely the LG G4.

The tonal transitions in Panasonic Z95A are not disastrous, but in this class of devices, one can expect more. The television struggles with smoothly blending colours, both in dark and light shades. In more demanding scenes, minor imperfections are visible, which can affect the visual experience, particularly for more discerning users. While this is not a disqualifying factor, it is an aspect that needs improvement, especially considering the price and ambitions of this model.

Once again, we will take a look at the function responsible for smooth gradation, but we will also address the one that aims to improve the quality of lower-quality materials. The default smoothing of tonal transitions, as we have seen, was not the worst, but it can still be improved. The function has a slider, which allows us to adjust its strength. We recommend using the first one, as it yields very good results and does not blur important details.

Image scaling in LG C4 is quite good; however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. Admittedly, there are jagged edges on the trees, but this is not a major issue compared to other manufacturers.

In the case of lower quality materials, the function "Gradation Smoothing" is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vivid and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noted, such as "jagged" edges, for example, branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the television to a very powerful PC. In other cases, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sport or content with a lot of motion dynamics. For those requiring high fluidity of the image, the manufacturer has implemented a multi-step 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 within a range from 0 to 10, with each degree affecting the degree of smoothing, allowing everyone to find their golden mean.

The LG OLED C4 panel features an average response time of less than 1 ms (which directly results from our measurements), allowing for an incredibly clear image that is unattainable for LCD televisions, whose response times can be as high as several milliseconds. This is clearly visible in the pictures from the "UFO Test," showing no trailing blur behind the object.

Panasonic Z95A, thanks to its 144 Hz panel, offers excellent image fluidity. For films, there is an "Intelligent Frame Creation" feature that enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in rapidly moving scenes. "Film Smoothness" – adds fluidity by creating additional frames between the originals, making motion appear smoother and more natural with a "soap opera" effect.

Thanks to this, viewers can adjust the settings to their own preferences. Films and less dynamic material look smooth and natural, which should satisfy most users.

We can already say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of compatibility with consoles and PCs. Thanks to the implementation of four full bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has included all features that enhance the gaming experience, among which we find simultaneous support for FreeSync and G-Sync technology. With such a tandem, gamers with a graphics card from AMD or Nvidia can confidently opt for C4. However, what should delight the players requiring the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The first is particularly important as it works with extremely low input lag in all settings.

A standard in the Korean manufacturer's televisions 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 visually impaired individuals, which is a very nice touch. Another important piece of information is that when VRR technology is enabled, we will not experience a drop in contrast. This is, of course, due to the panel's design and the absence 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 television.

In summary: LG C4, just like all of the manufacturer's OLEDs equipped with high refresh rate panels and HDMI 2.1 ports, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible performance in gaming, C4 will be an ideal choice.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers virtually everything one could expect from a device in this bracket. Support for ALLM (automatic low latency mode) and VRR (variable refresh rate) ensures smoothness and eliminates tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and additional support for resolutions other than 4K provides greater flexibility, which is a significant advantage for gamers using various configurations.

A unique and quite specific feature is the "Game Bar." Its ball-shaped interface stands out from the competition and allows for quick adjustments of key settings such as VRR, brightness level, or picture mode, without having to interrupt gameplay.

However, in this class of device, there is a minor disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely too few for a premium television, especially at a time when many people own more than one device requiring full HDMI 2.1 support, such as a next-gen console or an advanced computer. In this category, it's hard to accept this limitation, especially given the high aspirations of this model. Nevertheless, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.

The input lag of the LG C4 is at an incredibly low level in every scenario. Even the most dedicated gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is just 5 ms. It is also worth noting that the lag at the same settings but with Dolby Vision HDR enabled remains unchanged, which is not so obvious with the competition. Therefore, it deserves the highest rating and recommendation.

Panasonic Z95A delights with an exceptional level of input lag, making it one of the best choices for gamers in its class. Regardless of the mode, the television achieves results of around 13 ms at 60 Hz and just 5 ms at 120 Hz, ensuring incredibly smooth and responsive gameplay. Moreover, Panasonic allows playing in Dolby Vision mode with minimal delays. Well done!

LG C4 in combination with a PC performs excellently, thanks to a very low latency of just 13.5 ms, which is practically an instantaneous response between the mouse, eye and screen. A particularly important issue when working on the screen is the readability of text, which in the case of the tested television is very good. However, it is worth noting that to achieve sharp fonts, you need to enable the passthrough option in the settings.

The RWBG pixel arrangement has no significant impact on the display of fonts or letters, which is a considerable advantage over Samsung's QD-OLED panels. Users of both computers equipped with the Windows operating system and macOS will certainly be satisfied with the experience on the screen of the tested television.

Panasonic Z95A works excellently with computers, offering full chroma 4:4:4 support, which translates to very good font readability. However, one should bear in mind the characteristic way of displaying text of WOLED matrices with a white subpixel, which may be noticeable during prolonged work with documents or browsing websites. This is something worth considering if the television is to be used as a work monitor.

Additionally, the support for G-Sync technology is a plus, which is a great addition for gamers using NVIDIA graphics cards. This means that the Z95A provides smooth gameplay without tearing and delays, making it a versatile device for both work and play.

The undeniable advantage of OLED panels is their efficiency in the context of group viewing, that is, from various angles. LG C4 maintains very good contrast, colour saturation, and fidelity. Although this is not the result of organic televisions supported by MLA technology, it cannot be said that anyone who purchased the device was dissatisfied with the results obtained. However, it should be noted that at sharp angles, a slight greenish tint can be observed. This is a characteristic feature of WRGB panels from LG, without the aforementioned microlens technology, and unfortunately, there is nothing that can be done about it.

The viewing angles on the Panasonic Z95A are excellent, thanks to the use of an OLED panel with MLA technology. This ensures that the picture remains clear, full of detail, and without visible colour shifts even at large angles. In practice, this means that regardless of where we are watching the television from, the picture quality remains at the highest level.

In this respect, the Z95A ranks among the very best, competing for the title of leader with televisions based on QD-OLED panels (Samsung and Sony). It is difficult to find anything better on the market, making this model an ideal choice for larger rooms or screenings with family and friends, where everyone can enjoy a perfect picture.

The maximum brightness of the television in SDR materials is 367 nits. For an OLED television, this is a very good result that allows for quite comfortable viewing during the day. It is worth noting two things. Thanks to the glossy coating of the screen, reflections are held well in place and do not spill over onto the rest of the display. The second issue is the brightness of the screen at 100% white fill, which hovers around 220 nits, a remarkable result, as until recently OLED televisions in this range could only "boast" of brightness that was half as much. This means that conditions for watching, for example, winter sports will be very good.

Panasonic Z95A is equipped with a glossy panel that manages to reduce reflections quite well. However, due to the use of micro lens array (MLA) technology, blacks in bright environments may take on a slightly cherry hue, which is particularly noticeable in brightly lit rooms. In terms of brightness, the average SDR value is around 500 cd/m², which comfortably allows for enjoyable viewing of the television in most living rooms. However, it should be taken into account that in very sunny conditions or with intense artificial lighting, this brightness may prove insufficient to fully eliminate reflections and maintain perfect contrast. Nonetheless, in typical home conditions, Z95A performs very well.

LG uses the well-known proprietary WebOS system that has been around for many years. The system offers practically all the most important applications, and the few that are missing can be counted on one hand, such as CDA or KODI. It is also worth mentioning that the modern web browser and the remote control with a built-in mouse allow for convenient use of streaming services in this way, if there is no built-in application.

WebOS also features a highly valued ability to perform operations with a cursor that appears when the remote control is in motion. The convenience of such a function is invaluable when typing in queries or passwords for portals. WebOS, like most systems, also supports features such as screen mirroring, AirPlay, voice search in Polish, and the ability to connect headphones via Bluetooth. On more practical matters, WebOS allows simultaneous use of headphones and the TV speaker, which will certainly be a big help for people with hearing impairments. Among the more interesting features, particularly appreciated by sports fans, is the option to turn on an alert notifying about an upcoming match, ensuring that we never miss a broadcast. The home panel is also praiseworthy, allowing for the control of all smart devices connected to the home network. For example, the cycle of completed laundry will be signalled by a notification in the upper right corner.

In summary, the WebOS system, although less known and having certain limitations compared to Android TV, offers stable and fast performance and supports most features that users may need. It is a solid solution for those looking for a simple and effective operating system in their television.

Panasonic Z95A introduces a new operating system, which we believe is a very good move compared to last year's MZ2000 model. The system is called Fire TV and was created by Amazon. It is a novelty in the Polish market, distinguished by its fluidity and responsiveness, providing convenient operation and quick performance in everyday use.

Despite numerous advantages, the system still has a few shortcomings. We won’t find some popular applications on it, such as SkyShowtime, as well as Polish streaming services like Player.pl or TVP VOD. Another drawback is the quality of the interface translation – many functions have been translated in a rather imprecise manner, giving the impression that the translation was done "on the fly". Some names are incomprehensible, especially for those who haven't previously encountered other televisions, which can complicate the use of the device.

In terms of user functions, Z95A performs very well. It includes options such as USB recording, support for the PiP (picture-in-picture) function, AirPlay, and Miracast. As a result, the television offers versatility and meets most of the demands of modern users, although the Fire TV system still requires refinement to fully compete with more established solutions on the market.

The default file player in LG C4 definitely handles all image resolutions well. We can successfully play videos recorded in virtually all the most popular formats, including Dolby Vision. The only codec that the C4 does not support is H.266 VVC, although this is currently rather unused. However, it is a pity that subtitles in .txt format are not supported. Attention should be paid to the supported image formats, of which there are only three: JPEG, PNG, and, importantly for Apple phone users - HEIC. However, the tested television cannot be faulted for lack of diversity in audio files, the playback of which will not be met with a compatibility warning.

As we mentioned earlier, the Fire TV system in the Panasonic Z95A has some issues with support for the Polish language, which is unfortunately also noticeable when playing files from a USB drive. The built-in media player does not allow for the correct display of Polish characters, such as "ź", "ć" or "ł", which can be inconvenient for users relying on local subtitles for films. If the correct display of Polish characters is important to the user, it may be necessary to use an external application available in the Amazon store or to stream content through other devices.

The implemented audio system in LG C4 has been very well tuned, allowing us to experience strong bass, as well as balanced mid and high tones. We can confidently say that in its price range, it is one of the better sounding televisions. However, we believe that those deciding to purchase the C4 will already own a dedicated audio set. The presence of DTS-HD Master Audio and Dolby Atmos codecs will not be without significance.

The sound in Panasonic Z95A is one of its strong points, mainly thanks to the built-in soundbar, which provides impressive audio experiences. Dolby Atmos support makes the sound spatial and full of depth, perfectly fitting into the cinematic experience. Both dialogues and sound effects are clear and dynamic, which will satisfy even the most demanding users. Unfortunately, there is a lack of support for the DTS format, which may be disappointing for those using films or content that require it. Nevertheless, the overall sound quality in Z95A is at a very high level and successfully replaces external audio systems (at a reasonable price) in most home applications.
