avedio links 8K HDMI Splitter 1 in 2 Out - Mirror 8K/4K Duplicate

Our review finds the avedio links 8K HDMI Splitter 1 in 2 Out is a practical choice for someone who needs to mirror a single HDMI source to two displays with minimal fuss. It is designed for users who want to show the same 8K or 4K content on two TVs or a TV and projector at once, and the biggest reason to buy is its support for high-bandwidth HDMI 2.1 features like 8K@60Hz and 4K@120Hz so modern consoles and media players can display high frame rate video without a complicated setup. This review focuses on real-world use, compatibility limits, and the splitter's straightforward plug-and-play operation.

Key Features

• Mirror Output: Duplicates one HDMI input to two outputs simultaneously so both connected displays show identical content with no switching required.
• High Resolution Support: Handles up to 8K@60Hz and 4K@120Hz for sharp, high frame rate video on compatible sources and displays.
• HDCP 2.3 Compatibility: Uses upgraded HDCP 2.3 chips to work with most modern HDMI devices and protected streams.
• EDID Management: Auto and Copy EDID modes help match the best common resolution or force output 1s resolution for consistent playback.
• Wide Backward Compatibility: Backward compatible with 1080i, 720P, and 576P and supports HDR10, Dolby Vision, HDR10+, VRR and ALLM for gaming and HDR video.
• Plug and Play: No driver or software setup is required; connect source and two displays and the unit attempts to match the best shared resolution.

Who It's For

The splitter is best for homeowners, small venues, or gamers who want to mirror a single HDMI source to two displays, such as sending the same console output to a TV and a projector.
