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, allowing for a very realistic image. Of course, none of them surpasses the magical thousand, yet the combination of such results and unlimited contrast and black effectively boosts the outcome optically. The last of the scenes, featuring a full-screen burst of sunlight, is actually less bright than the others, although it still represents a commendable level. It is also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will allow for achieving extremely vivid colours.

The Panasonic W95B is truly a bright screen, capable of achieving a peak luminance of around 1400 nits. In brighter, well-lit film scenes, this value translates to spectacular HDR effects that can make a big impression. However, knowing our test setup, you can probably see that in very demanding shots – such as the moon in the distance or the lights of a helicopter in the scene from Sicario 2 – the television does not impress. In such situations, brightness drops to around 200 nits, which makes the HDR effect much less noticeable. This happens because Panasonic prioritises maintaining deep blacks, not illuminating the background – for many users, this shouldn't be a cause for concern. However, it is important to remember that in these moments the image begins to resemble SDR content. The coverage of the colour palette also deserves praise, as it reaches about 93% of the DCI-P3 space thanks to the use of a PFS filter (also known from QLED technology). As a result, most films look very good in terms of saturation and colours, preserving the cinematic character of the image.

The best factory mode implemented in the tested television was "Filmmaker". It was this mode that we used during all tests. This mode proved to be quite good in terms of colour reproduction; however, other shortcomings effectively detracted from the enjoyment of viewing. Starting with the most basic aspect, the white balance, it was easy to notice that it was marked by a dominance of red, which overall changed the characteristics of the image. We could thus see a strong yellowing of the whites and a shift of all colours towards warmer shades. The gamma, which is a curve just as important, if not more so, was quite significantly lowered, resulting in a considerable drop in contrast, except at the beginning of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Taking a closer look at films with a wide dynamic range, we can observe exactly the same phenomenon of yellowing of the white balance as in films with a standard colour palette. The EOTF curve, which replaces our gamma curve, 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 veers towards red, which may cause a subtle warming of the image, and the gamma curve is slightly elevated, making the screen appear a bit brighter. It is good that the manufacturer included this mode – even in factory configuration, it provides a reasonably natural appearance for films. However, knowing how susceptible Panasonic televisions are to calibration, we decided to see 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 therefore used them to model the image in the way that the director intended. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates that this is how a film should look. It is worth looking at the colour errors on the "ColorChecker" palette here, where practically none of them exceeds "1", apart from two samples.

After professional calibration, the Panasonic W95B shows what it is truly capable of. Colour errors have mostly dropped below values of 2–3, making them practically invisible to the human eye. It was also possible to correct the excess red in the white balance, which has resulted in the image no longer having a slight pink tint, and details in dark areas are no longer lost due to excessive dimming in the gamma. In HDR content, the improvement is also noticeable – colour saturation is now more stable and does not shift so markedly towards blue as it did before. This is truly an excellent television for watching films and series in the highest possible quality. While we know that Mini LED screens are not always perfect for this, the W95B is a perfect example that with proper fine-tuning, an effect close to OLEDs can be achieved.

Once again, we will take a look at the function responsible for smooth gradation, but we will also address the one that aims to improve the quality of lower-quality materials. The default smoothing of tonal transitions, as we have seen, was not the worst, but it can still be improved. The function has a slider, which allows us to adjust its strength. We recommend using the first one, as it yields very good results and does not blur important details.

Image scaling in 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. Admittedly, there are jagged edges on the trees, but this is not a major issue compared to 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 deal of detail and a natural appearance of contours. The final effect is impressive – the upscaling here 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 noteworthy. The algorithm does not operate as aggressively as in some competing models, but as a result, it does not cause a loss of detail or blur film grain.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the television to a very powerful PC. In other cases, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sport or content with a lot of motion dynamics. For those requiring high fluidity of the image, the manufacturer has implemented a multi-step 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 within a range from 0 to 10, with each degree affecting the degree of smoothing, allowing everyone to find their golden mean.

The LG OLED C4 panel features an average response time of less than 1 ms (which directly results from our measurements), allowing for an incredibly clear image that is unattainable for LCD televisions, whose response times can be as high as several milliseconds. This is clearly visible in the pictures from the "UFO Test," showing no trailing blur behind the object.

The 144 Hz panel used in the Panasonic W95B offers excellent fluidity, although in practice, due to the appearance of television content or the limitations of new generation consoles, it is worth observing its performance at a refresh rate of 120 Hz. In this mode, the television performs superbly – despite 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.

We can already say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of compatibility with consoles and PCs. Thanks to the implementation of four full bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has included all features that enhance the gaming experience, among which we find simultaneous support for FreeSync and G-Sync technology. With such a tandem, gamers with a graphics card from AMD or Nvidia can confidently opt for C4. However, what should delight the players requiring the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The first is particularly important as it works with extremely low input lag in all settings.

A standard in the Korean manufacturer's televisions is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly" without the need to exit the game. It also enables image adjustments for visually impaired individuals, which is a very nice touch. Another important piece of information is that when VRR technology is enabled, we will not experience a drop in contrast. This is, of course, due to the panel's design and the absence of conventional backlighting. However, it is 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 of the manufacturer's OLEDs equipped with high refresh rate panels and HDMI 2.1 ports, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible performance in gaming, C4 will be an ideal 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 that gamers can expect – perhaps except for four HDMI 2.1 ports, as there are only two available. Onboard, 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. It is all complemented by an interestingly designed Game Bar, presented in the form of circles. While it may not be the most visually attractive, it serves its purpose – allowing quick access to key game parameters and adjusting settings without entering the system menu.
