OREI 4x4 4K HDMI Matrix Switcher Splitter - Flexible Multi-Display

Our review of the OREI 4x4 4K HDMI Matrix Switcher Splitter finds it best suited for users who need reliable, flexible routing of multiple HDMI sources to multiple displays. The biggest reason to buy is its ability to connect four sources to four displays with full HDMI 2.0 and HDCP 2.2 support, delivering consistent 4K@60Hz HDR where available while also offering a practical built-in downscaler for 1080p screens. Setup is straightforward, and the device gives a professional-feeling solution for home theaters, small commercial installs, and mixed-resolution environments.

Key Features

• 4x4 HDMI Matrix: Routes any of four HDMI sources to any of four displays simultaneously, making it easy to mix and match inputs and outputs without swapping cables.
• 4K@60Hz HDR Support: Fully compliant with HDMI 2.0 and HDCP 2.2, it preserves Ultra HD signals with HDR and deep color for improved picture clarity on capable displays.
• Audio Extraction: Separate Optical (Toslink) and analog stereo outputs for outputs A and B plus ARC on output A allow feeding soundbars or receivers without extra adapters.
• 4K to 1080p Downscaling: The built-in downscaler ensures 4K sources can be displayed on 1080p screens in splitter mode, simplifying mixed-resolution setups.
• Plug-and-Play Operation: Designed for straightforward switching with remote control, it works well in installations where stability and ease of use are priorities.

Who It's For

The OREI 4x4 matrix is ideal for homeowners setting up multiroom entertainment, small sports bars or restaurants that need simultaneous playback on multiple TVs, and conference rooms that share several source devices across displays. It is also useful for surveillance and digital signage where multiple monitors require flexible source routing.

Those who should look elsewhere include users who need an enterprise-grade matrix with advanced network control or support for HDMI 2.1 features like 4K@120Hz or variable refresh rate, and anyone who requires integrated HDBaseT extenders for longer cable runs without additional gear.
