Govee HDMI 2.1 Sync Box 2 – AI Sync, 8K60/4K144, VRR, Matter, DreamView

Overview

Turn your 75–85 inch TV into a resonant viewing setup with the Govee HDMI 2.1 Sync Box 2. This AI-driven bridge pairs on-screen moments with synchronized lighting, offering a more immersive feel for gaming, streaming, and daily viewing. It supports high-resolution sources and fast refresh rates to keep pace with contemporary content.

Note: Automatic signal switching is not supported when multiple devices are connected. Plan your inputs accordingly to get the most seamless experience from your chosen source.

CogniGlow AI and performance

CogniGlow AI recognition analyzes content to trigger lighting effects that match scenes, text, and color cues. When combined with VRR and ALLM, you get smoother transitions and reduced perceived latency during dynamic moments.

• AI-driven scene detection for responsive lighting
• VRR and ALLM support for smoother gameplay and viewing

Vivid, accurate lighting with RGBIC

The RGBWIC four-color mixing delivers purer whites and richer color blending, enhancing game visuals and cinematic scenes alike. A high-density LED strip works in concert with the Sync Box for a brighter, more engaging glow.

• RGBWIC color mixing for accurate whites and vibrant hues
• 75 LEDs per meter and up to 450 lumens per meter for strong ambient light

Smart home compatibility

Built for modern homes, the system works with Matter, SmartThings, and Alexa for voice and routine-based control. Only lighting-related features are supported within these ecosystems, preserving focus on ambient lighting experiences.

DreamView and HDR considerations

DreamView lets you synchronize colors across multiple Govee lights to build an immersive environment that can complement Dolby Vision content and Dolby Atmos setups. If you enable HDR, HDR10+, or Dolby Vision, color saturation may appear slightly reduced—adjustment in the app offers a quick way to tailor results.

Practical use and setup tips

For larger living rooms and entertainment spaces, the high-density strip creates a noticeable halo that pairs well with cinematic scenes and fast-paced gaming. The device is designed to work with compatible sources, but not all combinations will trigger automatic input switching when multiple devices are in use.
