Samsung OLED S90D / S94D (WRGB OLED) vs Haier Q80FUX

In the tested film scenes, the Samsung S90D television achieves impressive brightness results, exceeding the 1000 nit barrier in the first four shots, which can be considered a remarkable outcome. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nit, but it still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour space coverage value of 98%, which guarantees extraordinarily rich and realistic colour reproduction, further enhancing the image quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

Alright, let's move on to the topic that really sparks discussions, which is the capabilities of the TV in HDR mode. Let's be clear from the start: the Haier Q80FUX is certainly not a brightness demon. The panel of this set can generate about 350 nits at peak, which in today's reality is an absolute minimum to even talk about the presence of HDR expanded dynamic range. On the plus side, this brightness is at least stable – regardless of the test pattern or film scene we used, measurements consistently hovered around 300-350 nits. These are at best adequate results, definitely far from the dazzling display of capabilities that we know from more expensive models. Fortunately, there is one aspect where the Q80FUX makes up for these shortcomings and does so considerably. We are talking about a QLED TV (or more precisely PFS LED), which means that thanks to the quantum dot filter used on the panel, it can generate truly juicy, vibrant colours. These are not empty promises – covering nearly 95% of the DCI-P3 colour gamut is an impressive result and directly translates into very pleasant, saturated colours for the eye.

The S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem too warm, and users who have switched from Standard mode might experience a slight shock. It’s worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to appear warmer than they should. In practice, this means that certain shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates slight fluctuations, which may result in the image being minimally darker, especially in the shadows. This can affect the clarity of details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is located above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, Samsung S90D delivers a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

Factory settings for movie mode are seldom perfect, but in the case of the Q80FUX, we encountered a noticeable imbalance. In SDR content, the image was definitely too warm, due to an excessive amount of red in the white balance, giving the overall picture a slight sepia tone. Conversely, in HDR materials, the television fell into the other extreme – an excess of blue caused an unnatural, cool effect in perception. However, it wasn't the fickle white balance that was the biggest issue with this TV. The real culprit, responsible for the previously described problems, was hiding deeper. It turned out that the Q80FUX has completely miscalibrated gamma values and, crucial for HDR, a poorly executed EOTF curve. It was these erroneous factory settings that caused the notorious clipping of the brightest parts of the image, imposing that characteristic milky filter over them. Thus, we found the source of the problem. This situation led to general, significant colour inaccuracies that were easy to catch even for an untrained eye. Like every television we tested, we decided to calibrate this model as well, and you can find the results of these adjustments in the next paragraph.

After calibration, the Samsung S90D TV in movie mode looks even better than one might expect. The white balance for both HD and 4K HDR content has been improved almost to perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, leading to a natural reproduction of details, especially in scenes that require a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of a wide colour gamut and does not offer as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

The contrast has also seen a significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between bright and dark areas of the image. The EOTF curve, which showed problems with overexposed scenes before calibration, now demonstrates better results. This effect allows for greater detail to be preserved in the bright parts of the image, especially in HDR materials.

The results of our calibration procedures must, unfortunately, be regarded as twofold. Generally speaking, the picture is undeniably better than before the adjustments; however, the biggest winner of this process has been SDR content. It is precisely here, after correcting the gamma curves and white balance, that we achieved results that can safely be called very good. Once set up, the Q80FUX truly shines in standard dynamic range, displaying only slight errors in the most challenging skin tones. Unfortunately, the weakest link remains HDR content. And here's the paradox: even though we managed to calibrate the white balance to near perfection, the overall colour errors still remain at quite a high level. The reason is that the television still interprets the static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate image clipping effect, which inevitably leads to significant distortions. Although we successfully eliminated the factory excess of blue, due to this electronic interference, the screen can still veer into somewhat too cool tones. That’s just how this television is.

Television S90D handles tonal transitions very well. Thanks to the technology used, transitions between colours are smoother and more natural. You can also use the noise reduction feature, which further smooths out tonal transitions, which can be useful in certain situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing out of desirable film grain, thereby reducing the cinematic feel of the image. For this reason, caution is advised when using this feature, as it’s better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels in scaling images from lower resolutions. The S90D Samsung TV effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-represented, showing no significant jaggedness that could degrade image quality. With effective scaling, even materials in lower resolution present attractively on the screen, satisfying users who prefer various sources of content such as regular antenna/cable television.

If there's one area where Haier clearly shows it still has a lot to catch up on compared to the market leaders, it's digital image processing. The upscaling, well... it's just okay. And that's really all that can be said about it. It does what it's supposed to do: ensures that lower resolution signals don't scare you with harsh pixelation on the screen and don't look like a forcibly enlarged postage stamp. However, it's far from the finesse and "intelligent" sharpening that more experienced players in this market have developed over the years. The biggest issue with the Q80FUX software is the almost complete lack of additional "cleaning" and smoothing features for the image. The receiver offers no noise reduction mechanisms or gradient enhancement. This means that with older or highly compressed materials, we simply have to accept that all the imperfections in tonal transitions or colour blending, which we mentioned earlier, will constantly accompany us during viewing.

Samsung S90D TV is equipped with a 120 Hz panel, with the ability to overclock to 144 Hz with the right PC configuration, providing exceptional motion smoothness. For years, Samsung has offered a variety of ten-point settings for image clarity, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any motion blur. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D an ideal choice for gamers and sports enthusiasts.

The issue of motion fluidity and blurring is largely predetermined by the use of a 60Hz panel, which naturally makes it difficult to recommend this receiver to enthusiasts of very dynamic content. Fortunately, in the Q80FUX, we find a few options (although, as will soon become clear, really just one) intended to enhance the experience with older film productions. There is a "De-Judder" slider available, which indeed affects motion fluidity and allows us to adjust it to our preferences: from raw, cinematic frame rates to a more theatrical, smoothed presentation. However, a true surprise awaits us right next to it in the menu. There is also a second slider, supposedly dedicated to removing blur – this is a feature we typically encounter in 120Hz panels, aimed at combating blurring in sports. As we expected, recalling memories from testing the K85F model, here too this slider is merely a façade. Its adjustment contributes absolutely nothing to the picture and simply seems to be an oversight by the product engineers who left a non-functional option in the software for this type of panel.

The Samsung S90D television is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly enhancing comfort and performance during intense gaming sessions. An additional advantage of the television is the special Game Bar, which allows for easy management of game settings. This functionality enables quick adjustments of parameters, such as changing the aspect ratio of the television screen, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the television while gaming even more convenient and enjoyable. As for PC users, the television pleasantly surprises. When connecting a computer, the panel is able to achieve a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. However, it should be noted that the television does not support Dolby Vision, which may be a downside – although it is worth considering that Dolby Vision is not as popular in the context of games as it is in films. Nevertheless, the S90D television still offers excellent features for gamers, making it a great choice for gaming enthusiasts looking for outstanding picture quality and modern technological solutions.

Entering the realm of gaming, the Haier Q80FUX proves to be quite a good companion for the "casual gamer." It is equipped with some highly sought-after features today such as VRR (variable refresh rate) and ALLM (automatic low latency mode). However, the biggest surprise is something else. Even though we don't have a 4K@120Hz panel here, the television can accept and display a 120Hz signal at a lower resolution (Full HD). This is a very useful feature, allowing you to consciously switch the console to a lower resolution mode in exchange for significantly higher fluidity, which is a perfectly acceptable compromise in the gaming world.

We won't particularly complain about the lack of additions like the "Game Bar," as it's just a nice extra. However, the most concerning issues arise when we enter the world of HDR in gaming. Due to the fact that the television continuously adapts the signal "in its own way," setting the brightness on the console according to the HGIG standard is almost impossible to accomplish according to the instructions. Worse still, in Dolby Vision mode for gaming, the input lag increases to around 50 ms, which is a high enough value that essentially makes this mode unusable. Generally speaking, we still wouldn't recommend gaming on this television in HDR mode, so these aren't that serious shortcomings. What’s most pleasing is the presence of 120Hz in Full HD, making the Q80FUX quite a cool television for the occasional gamer.
