Panasonic Z95A vs Philips OLED820

Panasonic Z95A demonstrates class when it comes to HDR performance. In brightness tests, it reaches a level of 1800 nits, which has a real impact on watching movies. Scenes from Life of Pi or Gemini Man look great – the television effortlessly reproduces details and the 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. Nonetheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers excellent coverage of wide color gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This ensures that colors are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colors appear 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. Thanks to this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel that we find in its biggest competitors – LG C5 or Samsung S90F. This means we can count on truly solid performance. This year, mid-range OLED panels are capable of exceeding the threshold of a thousand nits, and the model tested reaches around 1300 nits in some films. This is an outstanding result that allows for an extremely precise depiction of the director's vision, as contemporary productions are mastered in such brightness ranges. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the movie The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and wide coverage of the DCI-P3 color gamut at 99% make the picture simply look great.

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

In terms of gamma brightness characteristics, it performs very well, with only minor issues when lightening small details. The EOTF curve, which is responsible for controlling brightness in 4K HDR content, poses greater difficulty. Here, a slight boost in brightness above the reference value can be observed, making the image sometimes too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice in the Z95A, these aspects require refinement to fully exploit the potential of the television.

The color reproduction in the factory settings really surprised us, and positively so. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of color. The white balance was relatively accurate, though with a slight lack in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a flaw that particularly interferes with everyday viewing. A larger problem arose with the brightness characteristic. The gamma chart clearly deviated from the ideal, with the line being below the expected values, causing the image to be overly brightened, and the colors looked as if they were covered with a light milky filter. This effect was also noticeable in tests using the Colour Checker pattern, where more pronounced errors appeared.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect image. The television provides great adjustment capabilities, which we have fully utilized. The white balance after calibration is presented almost perfectly, and errors in SDR content at the level of 0.5 fall within an absolutely reference standard. The same is true for 4K HDR content – any pink tint on the screen has been completely eliminated, and the white balance is now exemplary.

The color palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 is a result that will satisfy both professional calibrators and enthusiasts of cinema-quality images. Significant changes have also occurred in brightness characteristics – the EOTF curve has been leveled, eliminating previous issues with excessive image brightness. And the small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it is a completely different league. It is a true 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 color reproduction.

After calibration, both the Filmmaker mode and the game mode gained quite a lot. A slight adjustment of the white balance and an improvement in brightness characteristics resulted in excellent outcomes for SDR content – the image looked almost perfect, natural and very close to the reference. In the case of HDR materials, the situation was similar; the colors looked stunning and it was hard to find anything to criticize. However, we noticed a certain feature that we had already pointed out when comparing scenes from the movie Billy Lynn. An analysis of the EOTF curve revealed that the television has a slight tendency to dim details in the blacks, which means that the darkest sections are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is remarkable, and the OLED820 stands out as one of the more interesting screens in its class. It just needs a little bit of fine-tuning, and there's really nothing to be afraid of.

In the case of lower quality materials, the "Gradient Smoothing" function 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 vibrant and pleasant to the eye, making lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noticed, such as "jaggies" on edges, e.g. branches in the background. Nevertheless, this does not significantly impact the overall viewing experience, and the television handles this material in an acceptable manner.

Fortunately, the earlier effects of the aforementioned posterization can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted color banding, improving the smoothness of tonal transitions. It does happen, however, that it works a bit too aggressively and smooths out some details – such as minor skin imperfections of the actors – but despite this, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes even too much so, although this can be alleviated by slightly increasing the sharpness in the picture menu – it’s a matter of personal preference. The lack of overscan issues with very low-resolution content is also commendable, meaning we don't have to worry that the image will be unnecessarily cropped.

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

As a result, viewers can adjust the settings to their own preferences. Films and less dynamic materials appear smooth and natural, which should satisfy most users.

Motion fluidity is an area where OLEDs always shine, and the Philips OLED820 confirms this rule. The panel itself offers a refresh rate of 144 Hz, which will mainly benefit PC gamers, but even with standard television sources or consoles, where 120 Hz is used, the motion is fast, sharp, and simultaneously smooth, without traces of ghosting. This is thanks to the outstanding response time between pixels, which ensures the image retains clarity in every dynamic scene. The manufacturer has also added its own smoothing feature called "Motion Style." In the menu, we find two sliders – the first, responsible for fluidity, allows us to adjust the amount of artificially added frames in movies. This way, we can choose a raw, cinematic character with a clearly visible film frame or a more theatrical image with smooth motion. The second slider is for reducing blurring, especially useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers practically everything one could expect from a device in this category. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a significant plus for gamers using various setups.

Attention should also be paid to the unique and somewhat specific "Game Bar." Its intuitive interface stands out from the competition and allows quick adjustments to key settings such as VRR, brightness level, or picture mode without interrupting gameplay.

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

Philips OLED820 is one of the most complete televisions for gamers. It practically has everything you could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (too bad there aren't four), variable refresh rate VRR, automatic game mode ALLM, support for Dolby Vision in games, and a good implementation of the HGiG mode. The television also handles lower resolutions at 120 Hz without any issues, so you can count on great flexibility when choosing different picture modes on the console. Philips also adds Game Bar – a panel that allows you to change picture modes, add a crosshair, or view parameters. Although it looks quite clunky and is less polished than that of the competition, it serves its purpose. In practice, therefore, the OLED820, besides having a full set of four HDMI 2.1 ports, offers almost everything a gamer might need.
