Govee AI Sync Box 2 (for 55-65, 75-85 inch TVs)

The Govee AI Sync Box 2 is an advanced TV backlighting device that uses the HDMI signal from your PC, gaming console, or any source, to provide a dynamic ambilight effect behind your TV or monitor, extending the display and enhancing immersion. There are two models: H6603 for 27-34 inch monitors, and H6604 for 55-65 and 75-85 inch TVs. 

The Sync Box itself also includes lighting that reflects the on-screen content. 

The AI Sync Box 2 adds support for HDMI 2.1 for up to 4K 144Hz gaming, while the "AI" part refers to specific lighting effects that will react to in-game events, such as being hit or winning the round. As part of a DreamView system, the Sync Box can also control a number of other compatible Govee lighting products. 

The AI Gaming Sync Box 2 supports Matter over Wifi for basic color selection; you'll need the Govee Home app for advanced scene choices and managing DreamView.
