Samsung QLED Q70D / Q74D / Q77D vs Panasonic W95B

The brightness of the Samsung Q70D is fairly average, yet it delivers a noticeable HDR effect. With brightness exceeding 400 nits, the distinction between SDR and HDR materials becomes evident. As observed in the discussion about contrast and black levels, the TV's performance varies across different scenes. In a scene featuring a bright sun against a darker foreground, the measured luminance is lower. However, in a scene with a large, bright light source dominating the frame, the TV achieves its peak brightness, reaching nearly 500 nits—a commendable result for its price range and display class.

Despite these strengths, the relatively low coverage of the wide DCI-P3 color gamut occasionally results in less vivid color reproduction. Even so, the TV offers rich colors and precise shade reproduction, enhancing the movie-watching experience. Furthermore, the Q70D excels in motion blur elimination during dynamic scenes, making it a solid choice for enjoying sports broadcasts and gaming.

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 Samsung Q70D is "Filmmaker," and it is the one we used when conducting various tests. Before the calibration process, it had several flaws that effectively prevented the conveyance of the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green colors. As a result, there was a characteristic yellow tint on the image, causing whites to appear yellowed and creating issues with skin tones, which were noticeably too warm. The reduced gamma in the standard color gamut materials caused a significant drop in the already low contrast. This resulted in an emphasis on details in the blacks but also in blown-out images in brighter scenes. The EOTF curve, in this case, turned out to be much better and only lightened those scenes with relatively low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, the frame from the movie "Billy Lynn" was unnaturally bright and lacking depth.

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.

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, where we can find 2-point and 20-point grayscale adjustments as well as advanced CMS. Thanks to this, we were able to significantly improve the quality of SDR and HDR materials. The vast majority of errors have been corrected, and the image that the Samsung Q70D now generates is definitely closer to the reference. Higher deltaE errors in the high dynamic range materials are primarily due to the display's insufficient luminance.

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.

The function responsible for improving gradation is named "Noise Reduction" in the menu. As we have confirmed, it is worth activating as it has a positive effect on tonal transitions. More importantly, it does not negatively affect film grain or fine details, which sometimes the competition "offers" us.

Image scaling in Samsung Q70D should be rated as average. The manufacturer aims not to artificially sharpen the image but to leave it naturally softened.

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 Samsung Q70D is the first model in the manufacturer's range to feature a 120Hz panel, resulting in more advanced motion smoothing capabilities compared to lower-category models. Within the menu, three functions are dedicated to improving motion fluidity: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." The third option will be discussed separately. The first function enhances sharpness during motion, while the second adjusts the degree of smoothing. The smoothness feature on the Samsung Q70D performs well, with each setting delivering a noticeable effect. This allows viewers to customise the level of fluidity, making it suitable for those who dislike the typical stuttering of films or enjoy watching sports. The accompanying picture illustrates a configuration with mild smoothing, avoiding the soap opera effect.

The panel employed in the Samsung Q70D offers a commendable response time for its class. While it won't deliver razor-sharp motion clarity, it is a strong choice for sports enthusiasts at this price point.

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 tested television, Samsung Q70D, has four HDMI 2.1 ports, all offering a bandwidth of 40 Gbps. Despite this, no negative effects were noticed during testing. More importantly, the TV supports all features associated with the HDMI 2.1 standard. This will certainly please gamers, as it ensures optimal gaming performance using a console or a PC. While HDR Dolby Vision is absent, the correct implementation of HGIG mode and the absence of any calibration checkerboard issues are noteworthy. Additionally, Samsung stands out by allowing gaming with the smoothness enhancer activated without significant performance degradation. This means that 30 fps titles are perceived similarly to those running at a native 60 frames per second.

Samsung was one of the first manufacturers to introduce the Game Bar, which has been consistently improved. It provides all necessary gameplay information and allows users to adjust "on the fly."

In summary, the Samsung Q70D performs excellently with both consoles and computers. All functions worked seamlessly, and there were no issues. The ability to activate the smoothness enhancer without a noticeable increase in input lag is a game-changing feature.

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.
