OREI 4K 1 in 8 Out HDMI Splitter 4:4:4 8-bit - Reliable 4K

In this review the OREI 4K 1 in 8 Out HDMI Splitter is presented as a practical solution for duplicating a single HDMI source to multiple displays. Its main appeal is straightforward: distribute one 4K@60Hz HDMI signal to up to eight TVs or monitors without complicated setup, making it useful for locations that need identical screens. The unit emphasizes broad audio support and HDMI 2.0 compatibility, but it is important to note that this splitter duplicates rather than extends displays, which influences whether it is the right choice for your setup.

Key Features

• 1 in 8 HDMI output: Sends one HDMI input to eight displays at once, simplifying multi-screen playback in public spaces or presentations.
• 4K@60Hz support: Handles Ultra HD 4:4:4 8-bit signals so compatible sources and displays can show high-resolution video with accurate color.
• Wide audio compatibility: Supports LPCM, Dolby-AC3, DTS 7.1 and advanced formats like DTS-HD and Dolby TrueHD so multi-channel audio is preserved when supported by the source.
• HDMI 2.0 and HDCP 2.2: Backwards compatible with earlier HDMI versions and includes HDCP 2.2 support to work with protected 4K content from compliant sources.
• Simple troubleshooting options: Offers EDID settings and recommends quality HDMI cables under 30 ft to help resolve signal or clarity issues.

Who It's For

This splitter is a good fit for small businesses, bars, restaurants, houses of worship, gyms and meeting rooms that need the same HDMI content on multiple screens. Installers who want a single-source distribution solution for displays and projectors will appreciate the straightforward duplication and broad audio support.

It is not suitable for users who need extended desktops or dual-screen extension from a PC or laptop, since the device will not create independent displays. Also, installers who require very long cable runs over 30 ft should consider signal boosters or alternate distribution methods for reliability.
