Accessibility Features in Smart TVs GARI (Generic)
Smart TVs have many different accessibility features built into them. In addition, there are TVs designed specifically for different disability groups.
The Global Accessibility Reporting Initiative (GARI) collects all of the information on smart TVs from each manufacturer and provides a detailed search capability to allow you to find smart TVs with just the features you are interested in. Because the TVs that are available change every month -- we do not list the individual models here in the Unified Listing. Instead, we provide this generic entry describing all of the different types of features that can be found in smart TVs from different manufacturers -- along with a link to the GARI site where you can find the latest information on which devuces are available with which features from each manufacturer and each area of the world.
