OREI 8K HDMI Splitter 1x8 - Mirror Any HDMI Signal for Multiple

Our review of the OREI 8K HDMI Splitter 1 X 8 focuses on whether it is a practical solution for anyone who needs to send the same HDMI signal to multiple screens. The bottom line: this splitter is best for installers, event techs, and serious home theater or gaming users who need reliable mirroring to up to eight displays and want modern format support. Its standout benefit is broad video and audio compatibility, including 8K and 4K at 120Hz pass-through and support for advanced HDR and Dolby formats, which keeps image and sound quality intact across every output.

Key Features

• 1 IN 8 OUT HDMI: Distributes one HDMI input to eight output displays so the same content appears simultaneously on multiple screens without extra players or splitters.
• High-resolution support: Handles up to 8K and 4K at 120Hz, plus HDR, HDR10, HDR10+, Dolby Vision, and HLG pass-through for superior picture fidelity on compatible displays.
• Wide audio compatibility: Supports LPCM, Dolby Digital and TrueHD, DTS and DTS-HD Master Audio, and DSD so multichannel sources remain intact when mirrored.
• Smart EDID management: Uses intelligent EDID handling to maximize compatibility across different displays and reduce handshake issues when connecting mixed-screen setups.
• International ready: Ships with a dual voltage power supply using a US plug and includes an adapter/converter for overseas use, simplifying installation for traveling rigs or global deployments.

Who It's For

The OREI 1x8 splitter is ideal for event producers, trade show booths, retail displays, conference rooms, and multi-screen home theater systems that require a single source mirrored to several TVs or projectors. It fits scenarios where image consistency and support for modern codecs and HDR formats matter.

It is less appropriate for users who need independent screens showing different sources (use a matrix switch for that) or for installations where long passive HDMI runs exceed recommended cable lengths without extenders. For simple two-screen needs a smaller splitter may be more cost efficient.

Pros & Cons

Pros

• Supports modern formats up to 8K and 4K@120Hz, preserving high frame rates and HDR features across outputs.
• Extensive audio format support keeps multichannel and lossless audio intact when duplicating signals.
• Smart EDID management improves compatibility with mixed display types, reducing configuration time.

Cons

• All outputs mirror the same source only, so it is not suitable where different content per display is required.
• Long cable runs or marginal HDMI cables may still require extenders or signal boosters for consistent results.
