Samsung QLED Q70D / Q74D / Q77D vs Samsung DU8002 (IPS)

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 HDR effect in the DU8002 television leaves much to be desired. A brightness level of 300 nits is not able to provide a true high dynamic range experience, making the content viewed resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brightness and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 color palette at 92%. As a result, the colors are vivid and saturated, which may satisfy viewers who prefer rich hues, even if the HDR effect does not fully meet expectations.

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.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue color, leading to a noticeable yellowing of the image, which can be seen, for example, in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar problem occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and color inaccuracies.

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.

Samsung is one of those companies that offers advanced tools for improving image quality in its televisions, including a 20-point white balance adjustment. Even with the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, performs really well - tests on the Colour Checker palette confirm accuracy at the level of 2–1.5, which demonstrates the significant capabilities of this television in color reproduction. In 4K content, although not as perfect as in lower quality material, the overall picture looks much better.

The gamma brightness has also been heavily adjusted, ensuring that the image is not overly brightened and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it becomes apparent that the television struggles due to its low contrast panel. The EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although structural flaws, such as the type of backlighting, cannot be completely eliminated, color accuracy is surprisingly good, especially considering its price.

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.

Smoothing tonal transitions on the DU8002 television leaves mixed feelings. Although the menu offers an option for smoothing tonal transitions, in practice it yields no results and can even generate unwanted side effects.

Nevertheless, the television handles upscaling, or digital image processing, excellently. The test chart featuring a model looked really good – the image is not overly jagged, and the overall presentation is decent and pleasing to the eye. This is definitely good news for those planning to watch traditional television on this model.

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.

DU8002 with a 60 Hz panel is a television that performs better for watching movies than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out motion and giving scenes a more fluid appearance, which is useful for movie screenings. In the context of gaming, this model will rather be suitable only for occasional entertainment.

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.

DU8002 is a television that will mainly serve as equipment for casual gamers. The 60 Hz panel does not provide the highest motion fluidity, so in dynamic games there may be a lack of that extra smoothness of the image. On the positive side, it features ALLM and HGiG functions, which automatically adjust image settings for HDR games, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. When choosing this equipment, we will have to make do if we expect a full set of gaming features.
