LG 55 B4 vs Panasonic W95B

The HDR brightness performance of the LG B4 is impressive, even though it doesn't surpass 1000 nits. Its luminance stability is consistently strong across various scenarios, delivering a reliable viewing experience. The only instance where the TV shows slight weakness is in scenes with large areas of bright white, which has long been a challenge for OLED technology. However, perfect contrast, deep blacks, and excellent brightness ensure a fully immersive HDR experience. Furthermore, the TV’s remarkable 99% coverage of the DCI-P3 colour gamut enhances its colour vibrancy, making images appear rich and visually striking. This level of colour accuracy and brightness balance firmly places the LG B4 among the top choices for HDR content.

The Panasonic W95B is truly a bright screen, capable of achieving peak luminance levels of around 1400 nits. In brighter, well-lit movie scenes, this value translates into spectacular HDR effects that can leave a big impression. However, knowing our test setup, you probably see that in very demanding shots – such as the distant moon or helicopter lights in a scene from Sicario 2 – the TV does not impress. In such situations, brightness drops to around 200 nits, making the HDR effect much less visible. This happens because Panasonic prioritizes maintaining deep black levels without lighting up the background – for many users, this shouldn't be a cause for concern. However, it's important to remember that in these moments, the image starts to resemble SDR content. The coverage of the color palette also deserves praise, as it reaches about 93% of the DCI-P3 color space thanks to the use of the PFS filter (also known from QLED technology). As a result, most movies look very good in terms of saturation and colors, maintaining a cinematic quality of the image.

The best factory preset offered by LG B4 is the "Filmmaker" mode, which we used throughout our testing. Straight out of the box, the TV delivered fairly accurate colour reproduction. However, the most significant issue in both SDR and HDR content was the white balance. In SDR, there was a noticeable red dominance, giving the image a distinct yellow tint, particularly evident in skin tones and whites. In HDR, this red hue persisted, but the lack of blue also introduced a greenish tint in certain scenes. Additionally, we observed some inconsistencies in grayscale and colour accuracy. Despite these shortcomings, the overall picture quality was still solid for most viewing scenarios.

In Filmmaker mode, the Panasonic W95B offers an image with quite accurate color reproduction, although it is not without minor imperfections. The white balance slightly leans towards red, which can cause a subtle warming of the image, and the gamma curve is slightly elevated, making the screen appear somewhat brightened. It’s good that the manufacturer has included this mode – even in its factory configuration, it provides a fairly natural look for movies. However, knowing how susceptible Panasonic televisions are to calibration, we decided to check how much the image could improve after professional tuning.

LG B4 has long been known for offering advanced calibration tools, and it remains one of the few manufacturers that allows such in-depth image adjustments. Thanks to these tools, we calibrated the device to an exceptional standard. The result was incredibly low deltaE errors, considered at a reference level. Both SDR and HDR content now display exactly as the filmmaker intended. This level of precision is one of the reasons LG TVs are frequently used as preview monitors in graphic design and post-production studios.

After professional calibration, the Panasonic W95B shows what it is really capable of. Color errors have mostly dropped below 2–3, making them practically invisible to the human eye. The excess red in the white balance has also been corrected, which has eliminated the slight pink tint, and details in dark areas no longer get lost due to overly strong dimming in the gamma. Improvements are also noticeable in HDR content – color saturation is now more stable and does not veer towards blue as clearly as before. It is truly a great television for watching movies and series in the highest possible quality. Although we know that Mini LED screens are not always perfectly suited for this, the W95B is an excellent example that with proper refinement, an OLED-like effect can be achieved.

In this section, we will revisit the smooth transition function while also examining how the TV handles lower-quality content. As we’ve found, the setting responsible for smooth gradation is generally effective, though it does have its drawbacks. While the function works well in SDR content, it becomes less useful in HDR content. Even at the lowest setting, it can blur important details, so we advise against using it in such cases.

The image scaling on the LG B4 is assessed moderately positively. While there is no noticeable edge doubling, the image tends to be somewhat "soft." This can be adjusted by tweaking the sharpness slider to improve the clarity.

In terms of image processing, the Panasonic W95B performs excellently. The proprietary processor responsible for digital image processing effectively upscales lower-resolution content to 4K, preserving a great amount of detail and a natural appearance of contours. The final effect is impressive – the upscaling is at a truly high level, and Full HD content can look surprisingly good. The way the television smooths tonal transitions in low-quality materials is also worth noting. The algorithm does not operate as aggressively as in some competing models, but as a result, it does not cause loss of detail or blurring of film grain.

The maximum refresh rate on the LG B4 is 120 Hz, the bare minimum for those requiring high image fluidity. The manufacturer has equipped the TV with a multi-stage motion smoother called "TruMotion." This feature is split into two sliders: one controls the sharpness of moving images (De-Blur) and the other adjusts judder (De-Judder). Both sliders can be set between 0 and 10, with each level affecting the smoothness, so users can easily find their preferred setting.

The LG OLED B4 panel boasts an impressive average response time of 0.1 ms (based on our measurements), delivering an exceptionally clear image that surpasses the capabilities of LCD TVs, which often have response times of several milliseconds. This is particularly noticeable in the "UFO Test" images, where no trailing blur is visible behind moving objects.

The 144 Hz panel used in the Panasonic W95B offers excellent smoothness, although in practice, considering how television content looks or the values to which next-generation consoles are limited, it's worth looking at its behavior when refreshing at 120 Hz. In this mode, the TV performs wonderfully – despite it being a VA panel, which is not known for the fastest pixel response times, motion blur here is minimal and difficult to detect with the naked eye.

The LG B4 has four full HDMI 2.1 ports, each providing 48Gbps bandwidth. This ensures smooth activation of all relevant features without issues, making the television highly suitable for gaming. With its low input lag and extensive functionality, including well-implemented HGIG mode and Dolby Vision gaming with low latency, the B4 is a strong contender for gamers who demand high quality.

A standout feature is GameBar, which allows for on-the-fly adjustments without interrupting gameplay, as well as image adaptations for those with visual impairments. Another key point is that when VRR technology is enabled, the television maintains its contrast, thanks to the OLED panel's structure, though slight flickering in grey shades is to be expected.

In conclusion, the LG B4 is an ideal choice for gamers, seamlessly combining high performance with excellent gaming features. Its 120Hz panel and HDMI 2.1 ports make it a standout option for those seeking top-tier gaming experiences.

Aside from the previously mentioned drawback related to the VRR mode, in which local dimming does not work, the Panasonic W95B is a true gaming monster. The television offers practically everything gamers can expect – except for four HDMI 2.1 ports, as there are only two available. On board, we find an auto low latency mode (ALLM), properly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. This is complemented by an interestingly designed Game Bar, presented in the form of circles. While it may not be the most visually appealing, it serves its purpose – allowing a quick glance at key game parameters and adjusting settings without entering the system menu.
