Buying Guide
- Purpose and placement: Decide whether you need HDMI distribution (extenders), a streaming media box, or in-wall cable management. For layout simplicity, wall-mounted or recessed solutions keep cords out of sight.
- Video and audio features: If you require high-definition distribution across rooms, prioritize HDMI over IP extenders with long range and low latency. For legacy displays, a digital-to-analog converter provides compatibility.
- Connectivity options: Look for devices with Ethernet, Wi-Fi, or both. A Gigabit Ethernet port and dual-band Wi-Fi support improve streaming reliability.
- Compatibility and standards: Check for 1920×1080 or higher support, as well as HDCP compliance where applicable. TAA compliance may matter for certain procurement requirements.
- Ease of installation: In-wall kits should include templates and clearly labeled instructions. Recessed outlets should be compatible with common wall thicknesses and mounting standards.
- Security and safety: UL certification on in-wall components and cable management accessories adds assurance of electrical safety in home setups.
- Future-proofing: Android TV boxes with Android 13.0 and WiFi 6 offer longer usability as streaming apps evolve. Consider storage capacity and expandability for apps and media files.
- Aesthetics and finish: Black boxes tend to disappear into AV racks or behind TVs; ensure the chosen solution matches room decor and mounting options.
