Sony Bravia 7 (XR70) vs Sony Bravia 9 (XR90)

Since we know that the television performs well with contrast, let's check how it fares in terms of HDR effects. The luminance graph shows the very high capabilities of this model – 1500 nits is truly an impressive result. HDR effects are particularly striking in scenes where most of the screen is covered in light, as seen in the 1st, 3rd, and 5th test scenes. Minor shortcomings, typical of this technology, are still noticeable with very small light effects, such as in the scene from the movie "Sicario 2," where brightness drops to 500 nits. Although these are not stunning results, they can be considered decent. Additionally, it is worth praising the television for its high coverage of a wide color gamut – DCI-P3 at 96%, which allows for vibrant, saturated colors.

The brightness performance of the Sony Bravia 9 is exceptional. Each scene reaches over 1500 nits, and the television can shine even brighter during movie playback. This level of brightness provides an extraordinary viewing experience, allowing for immersive interaction with high-quality video content. Thanks to its extensive coverage of the DCI-P3 colour gamut, the image is vibrant, and when combined with such high luminance, it almost feels alive. With its impressive peak brightness, viewers can fully appreciate the colour range, even in the most challenging scenes involving dynamic lighting changes. The Bravia 9 also supports Dolby Vision and HDR10 formats, further elevating the viewing experience.

The IMAX Enhanced mode on the Sony BRAVIA 7 television is definitely the best mode available on this model, although it is not without its flaws, as its name might suggest. The biggest issue is white balance – both in HD and 4K HDR content, there is a noticeable dominance of red color, which makes the image take on pinkish shades. This is particularly evident on the tested snow screen, where the pinkish hue becomes very noticeable. Errors in the Colour Checker test also confirm these deviations – although they are not catastrophic, there is a tendency to lean towards warmer tones. As for brightness characteristics, gamma remains at a decent level with a slight bump but without major issues. However, the biggest challenge is 4K materials. It is clear that the EOTF curve is significantly above the reference chart, which causes the image to become too bright.

The "IMAX Enhanced" factory mode has remained the best option in Sony televisions for years, and it was used throughout the entire testing process. While it aligns closely with the reference compared to other predefined settings, improvements could be made for a better viewing experience.

In SDR materials, the gamma shows a noticeable boost, which leads to over-contrasting the image. Additionally, the beginning of the graph deviates significantly from the reference, resulting in merged details in the darker areas, creating an unpleasant uniform blotch. The EOTF curve in HDR content, on the other hand, appears mostly correct, with only minor deviations from the reference.

However, the most prominent issues affect the white balance. There is a persistent green colour dominance, leading to problems with grey tones and overall colour misalignment. This imbalance in the white balance gives the image an unwanted greenish tinge, negatively impacting the overall visual quality.

Sony BRAVIA XR70 offers a wide range of tools that allow for customizing the picture to personal preferences, which has enabled us to make significant adjustments to the settings. The white balance has been free of the issue of red hue dominance – snow no longer ends up with pink shades, which was previously noticeable. Although one can detect minor deviations at the end of the white balance chart concerning a drop in blue color, they are acceptable and hard to notice in everyday use. The Colour Checker test confirms that color reproduction errors are no longer as pronounced and rarely exceed a value of 2, which is a very good result. As for brightness, gamma, while not requiring significant improvement, has been slightly adjusted. However, the most notable change has been observed in the EOTF curve – the television no longer has issues with overly brightening the entire image in 4K content. However, upon closer analysis and enabling EOTF characteristics in films, certain limitations of the television arise due to the previously discussed dimming algorithm. Some small elements may be slightly more illuminated, but these errors are so minor that most users will not notice them. Overall, the calibration results are very, very positive.

The colour reproduction after the calibration process on the Sony Bravia 9 is nothing short of excellent. Regardless of the signal, whether SDR or HDR, the image comes remarkably close to the director's intended vision. Nearly every flaw in the image has been meticulously modelled and corrected to a high degree.

This impressive result can be attributed to the advanced tools available for calibration, which Sony has been offering in its televisions for years. Notable tools include the 2- and 20-point grayscale calibration and a very comprehensive CMS (Colour Management System). These features allow for precise adjustments, ensuring that the colours and overall image quality are as accurate and faithful to the source material as possible.

Since we know that the television performs very well with high-quality materials, it is worth checking how it fares with lower-quality content. Here the television shows its potential, and the applied graphics processor works really well. On the test board with the light bulb, there are no visible issues with color transitions, and the smooth gradation function works very well – we recommend setting it to "Medium".

When it comes to digital processing, or so-called upscaling, the television sharpens the image quite a bit, which leads to slight aliasing, for example on branches in the background, but it does not remove desired details. Nonetheless, the overall appearance is truly attractive and may appeal to most users. However, if we prefer a softer, more plastic image, this effect can be reduced in the settings by adjusting the sharpening level to our personal preferences.

When analysing the quality of tonal transitions and image scaling, especially for lower-quality materials, the improvement after activating the function for tonal transitions is clear. By default, the quality is quite average, but once the function is turned on, even at the lowest setting, the results are among the best we've seen. This feature can be enabled without worrying about negative side effects, such as film grain blur.

Sony's "XR" processor, which the brand has been touting for several years, lives up to its reputation for image scaling. The image quality is incredibly sharp while maintaining a very natural look. This reinforces that Sony's processing technology is one of the best available, particularly when handling lower-resolution content.

The Sony BRAVIA 7 television with a 120 Hz panel will satisfy most users in terms of motion smoothness. Additionally, Sony offers the Motion Flow feature, which allows for the selection of three different picture settings, adjusting them to personal preferences: Smoothness – Film: This setting improves motion smoothness, giving the image a more cinematic or theatrical character. Smoothness – Camera: This setting provides even greater smoothness, useful when watching dynamic scenes such as sports broadcasts. Clarity: This setting focuses on minimizing noise and motion artifacts, resulting in a more stable and clear image.

The maximum refresh rate of the Sony Bravia 9 is 120 Hz, the minimum for those primarily watching sports or other high-motion content. This refresh rate ensures the image remains sharp and smooth, even during fast-paced scenes. For more demanding users, Sony has implemented an advanced motion smoothing system, divided into three distinct segments: Smoothness (Film), Smoothness (Camera), and Clarity. These settings can be adjusted to various degrees, allowing users to fine-tune the picture to their preferences. For example, a setting with slight smoothing can be used to avoid the "soap opera effect," delivering a more natural and cinematic viewing experience. This level of customisation ensures that viewers can find their ideal balance between smoothness and clarity.

Sony Bravia 7 has significantly improved its capabilities for cooperation with consoles compared to previous models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and it is compatible with graphics cards, ensuring smooth display. The auto low latency mode (ALLM) effectively reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look great during gameplay.

Sony Bravia 7 also offers a Game Bar feature that provides quick access to settings and allows monitoring of parameters during gameplay. An interesting option is the ability to enable a virtual crosshair on the screen, which can give a slight advantage in shooting games. However, compared to the Bravia 9 model, the HGIG feature in the Bravia 7 does not perform as well, which may be noticeable for more demanding gamers – especially since the HGIG mode is becoming more popular in the gaming world as the preferred method for reproducing HDR effects.

A downside is the lack of support for 1440p@120 Hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony Bravia 7 is equipped with two HDMI 2.1 ports, one of which is often used to connect an audio system via eARC, limiting the number of available ports for connecting next-generation consoles.

The Sony Bravia 9 television is equipped with four HDMI ports, but what is puzzling for a device of this class is that only two of them operate in the 2.1 standard. Despite this, it should not detract from the fact that nearly all features work excellently, providing a positive experience when using them. Games running in HDR10 or Dolby Vision benefit from low input lag, ensuring a comfortable gaming session. The solid implementation of the HGIG mode is a noteworthy feature, as, after proper calibration, it closely aligns with Dolby Vision.

Sony introduced the GameBar feature to its televisions last year, a standard for many manufacturers. This feature allows for quick adjustment of settings without exiting the game. Its implementation has been seamless, offering conveniences such as a crosshair grid, black level adjustment, and reducing the screen to gaming monitor proportions.

The Sony Bravia 9 will find its fans, particularly among PlayStation enthusiasts. It is a natural pairing since the console and the television share identical capabilities. However, more broadly speaking, despite the minor issues with Dolby Vision in games, the Bravia 9 remains a very good television for gaming overall.
