LG OLED C4 vs Panasonic W95B

The HDR performance of the LG OLED C4 is impressive, firmly placing it in the higher tier. Most films exceed 700 nits, delivering a highly realistic image. While none surpass the 1,000-nit mark, the combination of these results with the TV’s infinite contrast and perfect blacks significantly enhances the visual experience. The final scene, with a full-screen flash of sunlight, is slightly less bright than the others but still maintains a solid level of brightness. Another highlight is the excellent DCI-P3 colour gamut coverage, which ensures incredibly vibrant colours. The HDR technology in the LG OLED C4 delivers exceptional colour and detail reproduction. The dynamic tone mapping feature optimises brightness levels, ensuring ideal light reproduction in every scene, even in the most demanding high-dynamic films.

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 mode on the tested television was "Filmmaker," which served as the basis for all evaluations. In terms of colour reproduction, this mode performed reasonably well; however, certain flaws significantly detracted from the overall viewing experience. The most fundamental issue was the white balance, which exhibited a noticeable dominance of red, skewing the image characteristics. This resulted in a pronounced yellow tint to whites and a general shift of all colours towards warmer tones.

The gamma, an equally crucial—if not more important—aspect, was notably lowered, leading to a marked reduction in contrast. Additionally, the television frequently lost detail at the start of the gamma curve. These issues were most apparent in SDR content.

When examining HDR materials, the same yellowing effect in the white balance was observed, as seen with SDR content. However, the EOTF curve, which replaces the gamma curve for HDR, was near perfect and left little room for criticism.

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.

As mentioned, LG televisions come with advanced tools to facilitate an accurate calibration process. By utilising these tools, we meticulously adjusted the image to align with the director’s original vision. Without overstating, the results were outstanding. Both SDR and HDR content now achieve a level of visual fidelity that reflects how films are intended to be seen.

Examining the colour accuracy on the "ColourChecker" palette reveals impressive results, with almost all colour errors falling below a delta of "1," aside from two minor exceptions. Post-calibration, the LG OLED C4 demonstrated a marked improvement in colour reproduction, particularly in SDR and HDR modes. Testing the TV after calibration highlighted its capacity for delivering exceptionally accurate colours, underlining the high calibre of this model. The LG C41LA offers a stunningly precise colour palette, sure to satisfy even the most discerning viewers.

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.

Let us revisit the function responsible for smooth gradation and consider its role in improving lower-quality materials. The default smoothing of tonal transitions, while decent, can be further enhanced. The feature includes a slider for adjusting its strength, and we recommend selecting the first option. This setting strikes a balance, offering excellent results without compromising important details through unnecessary blurring.

The image scaling on the LG C4 is commendable, though not entirely without flaws. By default, the image appears slightly sharper, though not to an intrusive degree. While jagged edges on elements like trees are occasionally visible, this issue is relatively minor compared to similar offerings from other manufacturers.

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 LG G4 supports a maximum refresh rate of 144 Hz, achievable only when connected to a high-performance PC. Otherwise, the television operates at a maximum of 120 Hz, the recommended setting for viewing sports or content with fast-paced motion. For those prioritising smooth image quality, LG has included a versatile motion smoothing feature called "TrueMotion." This function is split into two adjustable sliders: De-Blur, which sharpens moving images, and De-Judder, which reduces jitter. Both sliders offer a range of settings from 0 to 10, enabling users to fine-tune the motion smoothness to their preference.

The LG OLED C4 boasts an impressive average response time of less than 1 millisecond, as confirmed by our measurements. This results in exceptional image clarity, far surpassing LCD televisions, which often have response times of several milliseconds. This clarity is evident in tests like the "UFO Test," 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 C4, like nearly all OLED televisions from the manufacturer, excels in its compatibility with consoles and PCs. With the inclusion of four full-bandwidth HDMI 2.1 ports supporting 48 Gbps, the TV incorporates a range of features to enhance the gaming experience. Notably, it offers simultaneous support for FreeSync and G-Sync, making it an ideal choice for gamers using AMD or Nvidia graphics cards. For those seeking the best possible gaming quality, the integration of HDR Dolby Vision and HGIG mode is particularly impressive. HDR Dolby Vision operates with remarkably low input lag across all settings, ensuring smooth and responsive gameplay.

A standout feature in LG's televisions is the GameBar, which allows users to adjust settings in real-time without leaving the game. This includes options for customising the image for viewers with visual impairments, a thoughtful addition. Additionally, enabling VRR (Variable Refresh Rate) does not result in a loss of contrast—a benefit of the OLED panel's self-emissive technology, eliminating the need for conventional backlighting. While some slight flickering of grey tones may occur, this is a characteristic of VRR technology across all manufacturers.

In summary: The LG C4, like the brand's other OLED models equipped with high-refresh-rate panels and HDMI 2.1, provides a seamless and immersive gaming experience. For gamers demanding top-tier performance, this TV is an outstanding choice.

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.
