We used the following calibration settings to review the Sony 55" A8G (XBR55A8G), and we also expect them to be valid for the 65" model (XBR65A8G). These settings should apply to most types of content, except for gaming or use as a PC monitor, which require a few additional changes, listed below.
One of the first things we did was disable all of the Power saving modes, as we don't want the TV to adjust the image during testing. From the Picture menu, we also disabled Auto picture mode, and Light sensor, as we don't want the picture settings changing during calibration.
For SDR content, there are six preset picture modes. We recommend choosing the 'Custom' picture mode, as it is the most accurate one out of the box, and allows for the most customization. We recommend leaving the Contrast to '90', Gamma at '0', the Black level at '50' and Peak luminance at 'High' For our calibration, Black adjust, and Adv. contrast enhancer were all disabled, but you should adjust these to your liking.
You should adjust the Brightness to your specific viewing conditions. Changing the brightness does not have any impact on the overall picture quality.
In the Clarity tab, we left Sharpness to the default value of '50,' which is the neutral setting. Reality Creation was left disabled, but you can enable it when watching lower resolution content, as it can help to improve the image quality. Random noise reduction, Digital noise reduction, and Smooth gradation were also left disabled, but they can help improve the image quality of low quality videos. We don't recommend leaving them enabled, as they can cause a loss of fine details in higher quality content.
HDR is automatically enabled for the native apps. When you start playing HDR content, a small HDR icon appears in the picture settings menu. Once you start playing HDR content, some of the settings change automatically, including the Brightness, which increases to 'Max.' We recommend the 'Cinema Pro' Picture Mode for HDR, and that the other settings are left to their default settings.
For HDR to work from external devices, the Enhanced Format option usually has to be enabled from the 'HDMI signal format' menu for the input you are using. Older devices may have compatibility issues if this option is left enabled, so it is recommended to only enable this setting for devices that require it.
The A8G supports Dolby Vision, from native apps and with most external devices. Some devices may require firmware upgrades in order to work with Sony's Dolby Vision firmware. As with normal HDR content, when you start playing Dolby Vision content, some settings change automatically. We recommend leaving these settings as-is, do not copy our SDR settings over.
If you find HDR content too dim, set Brightness to 'Max' and set Adv. contrast enhancer to 'High'. For an even brighter image, increase the Gamma slider.
Sony TVs usually feature great, highly customizable motion features, and the A8G is no exception. Although we disable most motion enhancing functions for most of our tests, you should adjust these to whatever looks best for you. Some settings, like motion interpolation settings, may need to be adjusted depending on the specific content you are watching.
Although we usually leave these settings disabled during testing, you should adjust the settings in the Motion tab to your liking, as different people prefer different levels of motion interpolation. If you want to enable motion interpolation, set Motionflow to 'Custom,' and adjust the Smoothness slider. Most of these settings will need to be adjusted depending on the specific content you are watching.
The Clearness option adjusts the A8G's black frame insertion (BFI) feature. We recommend this setting if you want clear motion.
The Sony A8G is able to remove judder from all sources, but some additional settings are required for some content. For a native 24p signal, like from a Blu-ray player, no additional motion settings are required. To remove judder from external 60p/60i sources, like a cable box, or for the native apps, set Motionflow to 'True Cinema', and set CineMotion to 'High'.
When the A8G's Black Frame Insertion feature is enabled, Motionflow must be set to 'True Cinema', and CineMotion must be set to 'High' to play 24p content without judder. With BFI enabled, 60p/60i sources always have judder.
From the base SDR and HDR settings, very few changes are required for a great gaming experience. When you start gaming, it is best to switch to the 'Game' Picture mode, in order to get the lowest input lag, and use the recommended settings for SDR or HDR. For HDR gaming, it is important to make sure that HDMI Enhanced Format is enabled for the input you are using.
Unlike TVs from most other brands, no special settings are required for PC use on the A8G. Just make sure you are using either the 'Game,' or 'Graphics' Picture mode, and that HDMI Enhanced Format is enabled for the input you are using. Both of these modes offer excellent low input lag, and display Chroma 4:4:4 properly, so that text is displayed properly.
When watching lower resolution content, the upscaling method may need to be adjusted depending on the specific format. The screen position and aspect ratio can be adjusted from the Screen page on each input.
Although we don't expect this to be an issue for most people, burn-in is a possibility on the A8G. There are a few options you should be aware of though, to ensure you get the most out of your new TV.
The Pixel Shift setting, as the name describes, shifts the entire image a few pixels to one side, and gradually shifts it in a different direction over time. This helps reduce the effects of burn-in from very small elements, like fine lines in a game HUD. We recommend leaving this enabled, the screen shift is not very noticeable unless you are using the TV as a PC monitor.
The Panel Refresh menu allows you to manually run a complete pixel refresh cycle. Sony recommends doing this a maximum of once per year.
The following are the results of the white balance and colorspace calibration on our unit. They are provided for reference, and should not be copied as the calibration values vary per individual unit even for the same model and same size as the TV we reviewed due to manufacturing tolerances. If you want to try them you will need to enter all values shown, as all of them are active at the same time. If you end up with worse picture quality, simply reset them to the default values.
