LG OLED C4 vs Panasonic W95B

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

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 moon in the distance or the lights of a helicopter in a scene from Sicario 2 – the television doesn’t impress. In such situations, brightness drops to around 200 nits, making the HDR effect much less noticeable. This happens because Panasonic focuses on maintaining deep blacks, not illuminating the background – which shouldn’t be a concern for many users. However, it’s important to remember that in such moments, the picture starts to resemble SDR content. The coverage of the colour palette also deserves praise, as it reaches around 93% of the DCI-P3 space thanks to the use of the PFS filter (also known from QLED technology). This means that most films look very good in terms of saturation and colours, maintaining a cinematic quality to the image.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

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

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

After professional calibration, the Panasonic W95B shows what it’s really capable of. Colour errors have mostly dropped below values of 2–3, making them practically invisible to the human eye. The excess red in the white balance has also been corrected, which means the image is no longer slightly tinted pink, and details in dark areas no longer get lost due to excessive dimming in the gamma. The improvement in HDR content is also noticeable – colour saturation is now more stable and doesn’t lean towards blue as distinctly as it did before. It’s truly a fantastic television for watching movies and series in the highest possible quality. While we know that Mini LED screens are not always perfectly suited for this, the W95B is a prime example that with proper tuning, a result close to OLEDs can be achieved.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on 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. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

In terms of image processing, the Panasonic W95B performs exceptionally well. The proprietary processor responsible for digital image processing effectively upscales lower resolution content to 4K, maintaining a high level of detail and a natural look to contours. The end result is impressive – the upscaling is truly top-notch, and Full HD content can look surprisingly good. Also noteworthy is how the TV smooths tonal transitions in low-quality materials. The algorithm doesn’t operate as aggressively as in some competing models, which helps avoid the loss of detail or the blurring of film grain.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level 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 in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

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

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, 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 the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

Aside from the previously mentioned issue related to VRR mode, where local dimming does not work, the Panasonic W95B is a true gaming beast. The TV offers practically everything that gamers could expect – perhaps apart from four HDMI 2.1 ports, as there are only two available. On board, we find automatic low latency mode (ALLM), correctly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. The whole package is complemented by an interestingly designed Game Bar, presented in the form of circles. It may not be the most visually attractive, but it fulfills its purpose – allowing quick access to key game parameters and adjusting settings without diving into the system menu.
