avedio links HDMI 2.1 Splitter 1 in 2 Out 8K@60Hz

This avedio links HDMI 2.1 splitter mirrors one HDMI source to two displays with full 8K@60Hz video, 7.1-channel audio pass-through, and smart downscaling for mixed-resolution setups.

Built for modern home theaters and gaming rigs, this 1-in-2-out HDMI 2.1 splitter lets you feed the same high-bandwidth signal to two HDMI sinks simultaneously—TV, projector, monitor, or an HDMI-input soundbar/AV receiver—while maintaining sync and fidelity. It includes a 4ft certified 8K HDMI cable and a Type-C 5V/1A power adapter to stabilize transmission and avoid signal dropouts. Note: it mirrors the source to both outputs (no extended desktop) and does not support ARC/eARC.

How does the splitter handle 8K and high-refresh gaming modes?

The splitter supports 8K@60Hz and a range of high-refresh modes like 4K@120/144Hz and 1080p@240Hz, ensuring compatibility with next-gen consoles and high-end PCs. It passes up to 48Gbps bandwidth and supports features such as VRR and ALLM for reduced latency and smoother gameplay when your devices support them.

• 8K@60Hz and 4K@120–144Hz passthrough with 48Gbps throughput
• Supports VRR and ALLM to improve gaming responsiveness
• Use HDMI 2.1 cables ≤6.6ft for guaranteed 8K performance

Will this work when my displays have different resolutions?

The unit includes a smart down scaler that detects each connected display and outputs compatible resolutions simultaneously, preventing one display from going blank or forcing both to the lowest setting. This enables one output to remain at 8K while the other shows 4K or lower without manual switching.

• Automatic mixed-resolution support (8K + 4K/1080p) without user intervention
• Prevents resolution conflicts and black screens on lower-resolution displays
• Maintains synchronized audio across both outputs

What audio and content protection standards does it support?

The splitter passes multichannel audio including Dolby formats up to 7.1 channels, letting you send full surround sound to an HDMI-input soundbar or AVR. It also supports HDCP 2.3 stripping/bypass for compatibility with protected content, so modern streaming devices and discs play without handshake failures.

• 7.1-channel audio passthrough and Dolby-compatible audio support
• HDCP 2.3 support for copy-protected sources
• HDR10+ and Dolby Vision metadata passthrough for improved color and contrast

How easy is setup and what’s included in the box?

Setup is plug-and-play: connect your source to the input using the included 4ft 8K HDMI cable, attach the two HDMI outputs to your displays, and plug in the Type-C 5V/1A power adapter. No drivers or menu configuration are required for standard mirroring use.

• Included: 4ft 8K HDMI cable and Type-C 5V/1A power adapter
• Plug-and-play with LED indicators for status and connection
• Clear labeling for input and two outputs simplifies installation

Who is this for: This avedio links HDMI 2.1 splitter is aimed at gamers, home theater enthusiasts, and professionals who need to mirror a single high-bandwidth source to two HDMI devices simultaneously—such as running a console to a TV and a projector, or feeding an HDMI-input soundbar while keeping a second display active. It’s especially useful where mixed-resolution displays exist or where HDR and high-refresh features are required across both outputs. Avoid it if you need extended displays, ARC/eARC functionality, or active switching between independent sources.
