Sony X90L vs Samsung Q6F (IPS)

HDR on the Sony X90L television looks promising. The luminance chart showed that the TV has a solid power reserve, reaching a maximum of 1000 nits in synthetic tests. But how does it perform in real scenarios? In scenes such as the first one from Life of Pi or the final sequence from The Meg, the TV can deliver this power on HDR content, achieving around 800 nits. Unfortunately, displaying small light elements on a black background, as in the scene from Sicario 2, poses greater challenges for the X90L – here the results reach about 600 nits. Despite this, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The color gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, indicating good color reproduction in HDR content.

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even speak of any "high dynamic range" effect, or HDR. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another problem is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and brightness can drop below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not top-notch, as the coverage of the DCI-P3 color gamut does not exceed 90%. As a result, colors in HDR content may just seem under-saturated.

The best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the color reproduction right out of the box is average. In the case of lower quality materials, such as HD – regular TV or YouTube – it is worth paying attention to the white balance. It is characterized by a deficit in red and an excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite decent, but a slight boost may cause the image to become washed out and appear as if it is behind a light fog.

In 4K HDR content, the situation looks a bit different. The white balance shows a significant boost in blue, which makes the image appear unnaturally sharp and gives it an artificial feel. Such an exaggeration in color reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L looks quite decent at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the appropriate brightness to avoid overexposing larger elements.

We tested the television in Filmmaker mode, which showed us two completely different faces of this model. Looking at SDR content, we were honestly shocked at how good this TV looks straight out of the box. It was really hard to nitpick anything here. Despite a slight “haze” in the white balance or somewhat brightened details in the blacks (which directly results from the IPS panel's design), color errors hovered around the “2” level. This is surprisingly good, even outstanding, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colors after switching to HDR mode was a very unpleasant surprise. The errors in color reproduction and palette were so huge that our charts literally ran out of scale. Of course, since Samsung even in such an inexpensive model offers very advanced calibration possibilities, we decided to approach the subject professionally and check what could be done about it during calibration.

Sony offers many tools to improve image quality, including two additional image modes that we decided to use during testing and apply calibration to them. This solution significantly facilitates the calibration work and is very effective, provided that the right tools are available. In the case of HD content, the white balance has been almost perfectly aligned – only one shade of gray exceeds the error value of "1", which is an excellent result. The same can be said about the brightness characteristic (gamma), which looks nearly perfect, with microscopic deviations of around 0.01.

In the case of 4K HDR content, the situation is not as ideal. Although the white balance has been significantly improved, it has not been possible to completely eliminate the dominance of blue color. Nonetheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that image distortions are practically unnoticeable. As for the EOTF curve, it is worth activating the filter in the upper right corner "EOTF in Movies" – the graph looks correct, but the television encounters difficulties illuminating very small elements, which results from the limited number of backlight zones. Despite these minor flaws, it is thanks to the calibration carried out that the IMAX Enhanced mode in the Sony X90L makes watching movies resemble a true cinema experience.

After our calibration, the colors in SDR mode looked even better – the result is quite surprising, as color errors at level "1" are something usually seen in devices costing several thousand dollars. In this regard, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our interference in HDR mode did not bring about a noticeable improvement. The television, due to its poor black levels and low coverage of a wide color gamut, still has significant problems with proper color saturation, especially red. This is an example of a device where HDR mainly exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

The Sony X90L TV features a tone transition smoothing function known as Smooth Gradation, which is incredibly effective. Even at the "low" setting, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which gives a natural effect and makes everything look cohesive. It is evident that the engineers really put effort into this aspect, creating a solution that impresses and works well in everyday use. Because of this, even when watching content like regular television or YouTube, where the image is not inherently stunning, one can enjoy a smooth, cohesive, and visually pleasing experience.

The Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good here, even for such a budget TV from the QLED series. The only downside is when we watch very low-resolution material, like 576p (typical for old DVD players) – then the image may be slightly cropped. This is because the TV does not allow for the Overscan feature to be turned off, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, which is the attempt to smooth the image from unwanted artifacts. Here, the TV completely fails. Although we find a function in the menu called "Noise Reduction", it yields no visible results regardless of the slider setting. The only thing it seems to do is introduce unwanted errors into the image. Despite its presence in the system, we definitely do not recommend using it.

Sony X90L with a 120 Hz panel is a great choice for both gamers and movie enthusiasts. The TV is equipped with the Motion Flow smoothness feature, which allows you to adjust motion smoothness using two sliders: "smoothness" and "clarity." The "smoothness" slider controls the level of motion fluidity, which helps reduce image stuttering, while "clarity" is used to reduce blurring and improve motion sharpness, which is especially useful in dynamic scenes.

The 60 Hz panel in the Samsung Q6F is the standard in this price range, which makes it a rather average model for dynamic sports or gaming. However, in the case of movies, the TV performs quite well thanks to the smoothing feature. The "Motion Smoothing" option allows you to adjust the fluidity of motion to your own preferences – from maintaining a cinematic feel to full fluidity.

Sony X90L is a television that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth play in high resolution and at a high frame rate. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which provides smooth gameplay without screen tearing. Game Bar is an additional advantage – an intuitive tool that allows for quick access to the most important settings and gaming features, making it easier to control gameplay.

Unfortunately, in terms of HDR in games, the Sony X90L has its limitations. There is no support for HGiG, a standard that many gamers consider essential for precise HDR reproduction in games. Although the TV supports Dolby Vision, which theoretically could improve image quality in games, the practical application of this feature is problematic. Dolby Vision in game mode is associated with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, it is not possible to enable Dolby Vision along with VRR. This means that despite numerous advantages, gamers seeking perfect HDR in games may feel a sense of disappointment.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does have features like ALLM (Auto Low Latency Mode) and VRR frame synchronization for consoles, the list of benefits pretty much ends there. Besides these basics, the TV offers nothing more that might satisfy those who spend a lot of time in front of a console. It’s a real shame that such a useful tool as Game Bar is missing here, which in Samsung’s higher models allows for quick control of game parameters. In terms of gaming, this is an absolutely basic model and is only suitable for "casual" gamers.
