avedio links HDMI Splitter 1 in 2 Out - Mirror 4K 1x2 Splitter

In this review the avedio links HDMI Splitter 1 in 2 Out is evaluated for anyone who needs to mirror one HDMI source to two displays without fuss. The bottom line: it is a simple, plug-and-play solution for duplicating video and audio to two TVs or monitors simultaneously, best for basic setups that do not require extended desktop or HDCP2.2 support. The unit's clear advantage is straightforward mirroring with included 4 ft HDMI cable and USB power lead, making it a practical choice for lobby displays, presentations, or home media where identical output on two screens is the goal.

Key Features

• Mirror Only: Duplicates the same HDMI input to two outputs so both displays show identical video and audio with no complicated configuration.
• 4K Support: Handles up to 3840x2160@30Hz so users can mirror 4K content at 30Hz and enjoy improved clarity on compatible displays.
• Backward Compatible: Works with common resolutions including 1080p@60Hz and 720p, making it suitable for older TVs and projectors.
• Plug and Play: No drivers required and HDMI v1.3/1.4 compatibility simplifies setup for non-technical users.
• Includes Accessories: Ships with a 4 ft high speed HDMI cable and USB power cable so the splitter is ready to run with a standard 5V USB adapter.
• Audio Pass-Through: Passes common audio formats such as DTS and Dolby variants so mirrored displays receive both sound and picture.

Who It's For

The splitter is ideal for small businesses, event hosts, or homeowners who need to show the same feed on two screens - for example, a reception area with two TVs or a conference room mirroring a laptop to a projector and a display. Its plug-and-play nature means it fits non-technical users who want a quick setup without software.

It is not for users who need extended desktop functionality, an HDMI switcher, or advanced HDCP2.2 protected 4K@60Hz distribution. Audiophiles wanting a dedicated audio extractor or anyone requiring higher frame rate 4K should look for a powered HDMI 2.0/2.1 solution instead.
