Samsung QLED Q70D / Q74D / Q77D vs Samsung Q60D / Q67D / Q68D

The brightness that the Samsung Q70D can offer is at a fairly average level, although it cannot be said that the HDR effect will be unnoticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR materials. As was the case in the paragraph about contrast and black levels, this time we can observe that the first scene, featuring a bright sun and a dark foreground, possesses the lowest luminance among the measured ones. The result, which can be considered very good for this price range and class of display, is the latter. In a scene where we see a large light source filling a significant part of the frame, the brightness of the television is at its highest, reaching nearly 500 nits. It is worth noting the quite low coverage of the wide DCI-P3 colour gamut, which occasionally results in noticeable gaps in the colour palette. Additionally, users can enjoy rich colours and high precision in shade reproduction, making movie screenings a special experience. It is also worth noting that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

The Samsung Q60D television, regardless of the scene being tested, achieves brightness above 500 nits, which is above average for this class of devices. Such a level of brightness allows one to experience a taste of true home cinema, with clearly visible details in bright parts of the image and well-reproduced contrast dynamics, especially when watching content from streaming platforms or movies played from Blu-ray. As a result, film screenings gain greater depth and realism, particularly in well-lit scenes. Despite the use of quantum dot technology (QLED), the television does not achieve outstanding results in colour reproduction. The coverage of the DCI-P3 colour space is only 90%, which may be noticeable in more demanding scenes, where the richness and saturation of colours play a key role in image quality.

The best factory mode on the Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before calibration, it had several flaws that effectively prevented it from conveying the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green. As a result, there was a characteristic yellow tint on the image, causing white to appear yellowed and resulting in skin tones that were noticeably too warm. The lowered gamma in standard colour gamut materials resulted in a significant drop in contrast, which was already not the highest. This caused detail in the blacks to be accentuated but also led to overexposure in brighter scenes. The EOTF curve, in this case, proved to be much better and only brightened those scenes with relatively low luminance. This was perfectly evident in the section where we measured the television's maximum brightness in HDR materials. At that point, the frame from the film "Billy Lynn" was unnaturally bright and lacking in depth.

Samsung has been offering a "Filmmaker" mode in its televisions for several years, aimed at providing the most faithful picture settings straight from the factory, in accordance with the vision of filmmakers. This is certainly a significant step towards cinematic quality at home; however, it is worth noting that this mode is not without its problems.

For instance, the white balance in both SDR and HDR modes exhibits an excessive amount of red hue, causing the picture to appear too warm. As a result, the skin of actors and bright scenes may seem unnaturally pinkish. The Colour Checker test further confirms this issue – colour samples often shift towards red tones, deviating from the neutral colour reproduction that would be more desirable in a professional setting.

When it comes to contrast, there is a noticeable drop at the beginning of the gamma graph, where values below 2.4 drop all the way down to 2.1. Consequently, the image in darker scenes may appear less distinct, losing depth. In terms of HDR content, the EOTF curve (responsible for brightness reproduction) shows a strong spike at the beginning of the graph, which may lead to excessive brightness in the lighter parts of the image, disrupting the natural tonal balance.

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, including 2-point and 20-point grey scale adjustment as well as advanced CMS. This allowed us to significantly improve the quality of SDR and HDR content. 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 wide dynamic range content are primarily due to the display's insufficient luminance.

After professional calibration of the Samsung Q60D television in film mode, users can enjoy a significant improvement in image quality. Samsung televisions have always offered 2- and 20-point grey scale adjustments, as well as an advanced CMS (Color Management System), which allows for precise colour and shade adjustments. The white balance for both SDR and HDR has been free from strong spikes and tendencies for colours to shift to red hues, greatly enhancing the naturalness of the image. Although a few more significant errors can still be observed in HDR mode, the overall colour reproduction quality has been excellently improved. Regarding contrast, although drastic changes cannot be mentioned due to limitations in the television's technology, the improvement is noticeable. Thanks to calibration, details in dark scenes are more visible, and the differences between light and dark elements of the image have been enhanced. This makes the overall viewing experience more satisfying, allowing viewers to enjoy greater depth and realism in the displayed content.

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

The image scaling on Samsung Q70D should be rated as average. The manufacturer does not intend to artificially sharpen the image, but rather to leave it naturally softened.

However, when it comes to processing and scaling lower quality materials, the television performs quite well. The image is rendered without overscan, which ensures full use of the available screen area. Additionally, the outlines of the model or the branches of the tree are not overly jagged, which translates to a satisfactory quality of the displayed content. Although noise reduction could be more effective, the overall results of processing lower quality materials are positive and meet expectations.

Samsung Q70D is the first model in the manufacturer's portfolio featuring a 120Hz panel. Consequently, its motion smoothing functions are more advanced than those in lower-tier models. Within the menu, we find three functions responsible for improving smoothness: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We will discuss the third one later. The first function is responsible for sharpness in motion, while the second adjusts the level of smoothing. The smoother in Samsung Q70D performs satisfactorily, and each setting brings noticeable changes. Therefore, those who dislike the characteristic juddering in films or are avid sports viewers will be able to achieve a personalised level of smoothing. In the picture, we present a setting with slight smoothing, without the soap opera effect.

The panel used in Samsung Q70D features a fairly good response time for this type of display. Of course, it won't be as sharp as a proverbial razor, but at this price, it is a recommendable choice for all kinds of sports.

Samsung Q60D is equipped with a 60 Hz panel and a film smoothness enhancement option known as "Motion Blur Reduction." This feature aims to minimise motion blur and enhance overall image smoothness, which will certainly appeal to users who are primarily looking for a television to watch films and series. Thanks to this technology, viewers can enjoy a more fluid visual experience, even in dynamic action scenes where details are crucial. However, it is worth noting that while "Motion Blur Reduction" improves the smoothness of images in films, for gaming, this panel may not be the best choice as it exhibits significant motion blur, which can be seen in the picture below.

The tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the conducted tests, we did not find any negative effects related to this state of affairs. Moreover, and more importantly, Samsung Q70D supports all functions resulting from the aforementioned standard. This news will surely please all gamers, as it means that whether using a console or a PC, we can count on the highest possible comfort during gameplay. Given the typical absence of HDR Dolby Vision for this manufacturer, it is significant that the HGIG mode has been correctly implemented and there is no issue with setting the calibration checkerboard. We particularly note that Samsung, as the only manufacturer, allows gameplay with the smoothener turned on, without significant degradation. This means that titles running at 30 fps will be perceived like those with native 60 frames per second.

Samsung, as one of the first manufacturers, introduced the Game Bar to its televisions, which it has consistently refined since then. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

To summarise: Samsung Q70D performs excellently both with a console and a computer. All functions worked perfectly and there were no issues with them. The ability to enable the smoothener without a significant increase in input lag is a true game changer.

Samsung Q60D is equipped with features such as ALLM (Auto Low Latency Mode), HGiG (HDR Gaming Interest Group) and Game Bar, which significantly enhance the gaming experience. However, the lack of HDMI 2.1 implementation limits capabilities, preventing the use of VRR (Variable Refresh Rate), which could further improve smoothness and picture quality. Overall, for casual gamers, this television should perform well in everyday use, providing satisfactory gaming experiences. However, if we are more demanding in terms of gaming, it is worth considering models with a higher refresh rate and HDMI 2.1, which will ensure full functionality and better support for the latest games. In such cases, investing in a more advanced television will yield significantly better results in terms of smoothness and picture quality, which is crucial for gaming enthusiasts.
