Sony X75WL vs Panasonic Z95A

The luminance chart for the Sony X75WL revealed a peak brightness of just 350 nits, which is underwhelming for an HDR-capable display. This limited brightness means that HDR scenes lack the depth and impactful highlights expected for immersive viewing. Additionally, the subpar coverage of the DCI-P3 colour gamut results in a less vibrant colour representation, negatively impacting the overall quality of HDR content. The combination of insufficient brightness and poor colour gamut coverage significantly diminishes the intended HDR effect, making this model a less compelling choice for those prioritising HDR performance.

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.

Colour reproduction tests on the X75WL model, conducted in movie mode, reveal strengths and weaknesses. While movie mode offers some of the best image settings, it is not flawless. One of the most significant issues with the X75WL is the white balance, particularly for HD and 4K HDR content, where a blue hue dominates the image. This results in a noticeably cold tone throughout. The colour checker confirms these discrepancies, showing a clear shift towards cooler shades.

Regarding brightness, the contrast gamma level is generally acceptable, but the EOTF curve presents more challenges. There are noticeable problems with maintaining consistent brightness, with the image sometimes appearing too washed out or too dim. These issues affect the overall visual experience and hinder the accurate perception of content.

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 X75WL is one of those cases where image calibration may not lead to a dramatic transformation, but it does offer a notable improvement in colour perception. The white balance for HD and 4K content, has been significantly enhanced, eliminating the strong dominance of cooler tones. The gamma chart also appears more stable, resulting in better image quality overall. However, the main issue remains the EOTF curve, which controls brightness in 4K content. Due to the technological limitations of the television (such as the IPS panel and the absence of local dimming), a significant improvement is difficult to achieve, as the model’s capabilities are constrained. Despite these limitations, the tonality of the image has been substantially improved.

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.

The X75WL struggles with low-quality tonal transitions. The lack of any function to improve tonal gradation results in noticeable imperfections in colour transitions, which detracts from the overall image quality. However, the digital processing is commendable, with the image displayed without overscan, and relatively sharp presentation. This added sharpness may appeal to some users, though it does not compensate for the tonal transition issues.

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.

The X75WL features a 60 Hz panel, making it more suited for movie-watching than high-speed gaming. It is equipped with a motion smoother function called Motionflow, which allows users to adjust picture fluidity on a 10-point scale. This function adds intermediate frames, improving motion smoothness and creating a more cinematic effect by reducing choppiness. Additionally, the clarity adjustment helps reduce motion blur, making it particularly beneficial for fast-paced scenes like sports or dynamic action sequences in films. With these settings, users can fine-tune the fluidity and sharpness of motion to their preferences.

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.

The X75WL is not the best television for gamers, as it lacks some key features that more demanding users expect. While it includes the Auto Low Latency Mode (ALLM) and a basic Game Bar, these are not sufficient for a truly immersive gaming experience. In this price range, features like VRR (Variable Refresh Rate) and a 120 Hz refresh rate—at least in Full HD—have become standard, but unfortunately, these are missing in the X75WL. This is a significant drawback for Sony, as the competition offers more advanced gaming features at a similar price.

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.
