A9F

A9F is a model designation used by Sony Electronics for a 2018 4K OLED television in the Master Series lineup. It followed earlier A-series OLEDs and was positioned as a premium flagship for picture and audio quality. The set uses an OLED panel and includes Acoustic Surface Audio+ technology, which produces sound through the screen itself. It is powered by Sony’s Picture Processor X1 Ultimate to enhance upscaling, contrast, color processing, and object-based HDR remaster, enabling strong performance with high dynamic range content.

Smart features and connectivity are built around the Android TV platform, with Google Assistant and Chromecast built-in for app access, voice control, and streaming. The A9F supports high dynamic range formats such as HDR10, Dolby Vision, and HLG, and offers multiple HDMI inputs along with standard wireless options like Wi-Fi and Bluetooth. The display is available in several sizes, notably 55-inch and 65-inch configurations, offering wide viewing angles and strong black levels typical of OLED panels.

In reception, the A9F was praised for its image fidelity, color accuracy, and the unique screen-integrated sound system. It represented Sony’s emphasis on a streamlined, high-end viewing experience in the Master Series. As a late-2010s model, it has since been superseded by newer OLED offerings, but remains noted for its combination of picture quality and screen-driven audio in its era.
