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

The brightness that the Samsung Q70D can offer is at a rather average level, although it cannot be said that the HDR effect will not be noticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR content. As was the case in the paragraph about contrast and black levels, we can also observe here that the first scene, featuring a bright sunny sky and a darker foreground, has the lowest luminance of those measured. The result, which can be considered very good for this price range and display class, is that one. In a scene where we see a large light source filling a significant portion of the frame, the brightness of the TV is at its highest, reaching nearly 500 nits. However, it is worth noting the rather low coverage of the wide DCI-P3 colour gamut, which sometimes results in noticeable shortcomings in the colour reproduction. Additionally, users can enjoy rich colours and high precision in rendering shades, making movie screenings a unique experience. It is also worth mentioning that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

Television Samsung Q60D, regardless of the tested scene, achieves brightness levels above 500 nits, which is above average for this class of devices. Such a level of brightness allows for a taste of true home cinema, with clearly visible details in bright areas of the image and well-rendered contrast dynamics, especially when watching content from streaming platforms or films played from Blu-ray. This means that movie 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 in Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before the calibration process, it had several flaws that effectively hindered the presentation of the director's intentions. In both SDR and HDR material, the white balance was dominated by red and green colours. As a result, there was a characteristic yellow tint on the image, which caused whites to appear yellowed and skin tones to be noticeably too warm. The reduced gamma in standard colour palette materials caused a significant drop in contrast, which was already not the highest. This led to the highlighting of details in the blacks, but also to clipping in brighter scenes. In this case, the EOTF curve proved to be much better and only brightened those scenes with quite low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, a shot from the film "Billy Lynn" appeared unnaturally bright and lacking depth.

Samsung has been offering a "Filmmaker" mode in its TVs for several years now, aimed at providing the most faithful picture settings straight from the factory, in line with the vision of filmmakers. This is certainly a big step towards cinematic quality at home, but it is worth noting that this mode is not without its issues.

For example, the white balance in both SDR and HDR modes exhibits an excessive amount of red, which makes the image too warm. As a result, the skin tones of actors and bright scenes can appear unnaturally flushed. The Colour Checker test further confirms this problem – colour samples often shift towards red hues, deviating from the neutral colour representation that would be more desirable in a professional setup.

When it comes to contrast, there is a noticeable strong drop at the beginning of the gamma graph, where values below 2.4 drop all the way down to 2.1. As a result, the image in darker scenes may appear less distinct, losing depth. In the case of HDR content, the EOTF curve (which is responsible for brightness reproduction) shows a strong spike at the beginning of the graph, which can 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 TVs, including 2- and 20-point grey scale adjustments and advanced CMS. As a result, we were able 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 delivers is definitely much closer to the reference. Higher deltaE errors in wide dynamic range content primarily result from 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 grayscale adjustment and an advanced CMS (Colour Management System), allowing for precise colour and shade adjustments. The white balance for both SDR and HDR has been stripped of strong peaks and tendencies towards colour drifting into red tones, significantly enhancing the naturalness of the image. Although a few larger errors can still be observed in HDR mode, the overall quality of colour reproduction has been excellently improved. Regarding contrast, although drastic changes cannot be said due to the limitations of 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 perception of the image more satisfying, allowing viewers to enjoy greater depth and realism in the displayed content.

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

The image scaling on Samsung Q70D should be rated as average. The manufacturer does not aim to artificially sharpen the image, but rather to keep 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 space. Additionally, the outlines of the model or branches of the tree are not overly jagged, resulting in a satisfactory quality of the displayed content. Although noise reduction could be more effective, the overall processing results of lower quality materials are positive and meet expectations.

Samsung Q70D is the first model in the manufacturer's portfolio with a 120Hz panel. As a result, its motion smoothing features are more advanced than those in lower-tier models. In the menu, we find three functions responsible for improving fluidity. They are "Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We'll discuss the third one later. The first function enhances sharpness in motion, while the second adjusts the level of smoothing. The smoothness enhancer in Samsung Q70D works satisfactorily, and each setting makes a noticeable difference. Therefore, those who dislike the characteristic stuttering of films or who passionately watch sports will be able to achieve their preferred level of smoothness. In the image, we present a setting with slight smoothing, without the soap opera effect.

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

Samsung Q60D is equipped with a 60 Hz panel and a feature to enhance movie smoothness, known as "Motion Blur Reduction." This function aims to minimise motion blur and improve overall image fluidity, which will certainly appeal to users who primarily seek a television for watching movies 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 image fluidity in films, for gaming, this panel may not be the best choice due to its considerable motion blur effect, which can be seen in the photo 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 testing process, we did not observe any negative effects associated with this situation. More importantly, Samsung Q70D supports all features stemming from the aforementioned standard. This news will surely delight all gamers, as it means that whether using a console or a PC, we can expect the highest possible comfort during gameplay. Given the standard absence of Dolby Vision HDR for this manufacturer, it is significant that the HGIG mode has been implemented correctly and there are no issues with setting up the calibration chessboard. We particularly note that Samsung is the only manufacturer to allow gaming with the smoothness enhancer switched 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 has since been consistently refined. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

In summary: Samsung Q70D will perform excellently both with consoles and with computers. All functions worked brilliantly, and there were no issues with them. The ability to enable the smoothness enhancer without significant increases in input lag is a true gamechanger.

Samsung Q60D has been 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 its capabilities, preventing the use of VRR (Variable Refresh Rate), which could further improve smoothness and image quality. Generally, for casual gamers, this TV 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 TV will yield significantly better results in terms of smoothness and image quality, which is crucial for gaming enthusiasts.
