OREI 1x4 HDMI 2.0 Splitter with Scaler Audio Extractor - 4-Port 4K

In this review the OREI UHDS-104A is evaluated as a compact solution for anyone who needs to send one HDMI source to multiple displays while keeping audio options flexible. The bottom line: it is best for home theater setups, small conference rooms, or gamers who want identical 4K@60Hz feeds to several TVs or projectors and need a simple way to extract analog or optical audio. Setup is straightforward, and the main draw is reliable video scaling and broad audio format support from a single, bus-powered box.

Key Features

• 4K@60Hz support: Handles resolutions up to 4K x 2K at 60Hz so modern 4K sources display at native resolution on compatible screens.
• HDMI 2.0 with EDID control: Uses HDMI 2.0 and EDID handling to help match output resolution and format to connected displays.
• 1x4 splitting: Splits one HDMI input into four identical outputs so the same video plays on multiple TVs or projectors simultaneously.
• Audio extraction: Built-in analog and optical audio outputs let installers feed sound to a receiver or soundbar without tapping into the TV.
• Scaler capability: Can scale resolutions to match different displays, reducing manual configuration when screens differ.
• Wide compatibility: Works with common HDMI sources such as streaming boxes, game consoles, Blu-ray players and PCs.

Who It's For

The UHDS-104A is ideal for homeowners running a multi-TV setup, small businesses that need the same presentation on several displays, and gamers who want consistent 4K output to multiple screens. Its audio extractor is also useful for setups where the display lacks a convenient audio output or where a separate sound system is preferred.

It is not aimed at long cable runs or complex AV installations that need advanced matrix routing, professional-level EDID management, or distribution to dozens of endpoints. For very long HDMI runs beyond about 30 ft, or for installations requiring managed switching and switching latency guarantees, a more robust distribution system would be a better choice.

Pros & Cons

Pros

• Reliable picture quality and support for 4K@60Hz preserves source clarity across multiple displays.
• Flexible audio extraction with both analog and optical outputs supports a wide range of sound formats.
• Simple setup and broad compatibility with common HDMI devices makes it user-friendly for non-technical users.
• Includes dual voltage power supply and international adapter for easy worldwide use.

Cons

• Some users report mixed functionality depending on specific device combinations, so certain source/display pairings may need troubleshooting.
• Recommended cable length is 30 ft or shorter, so it is not optimized for very long runs without signal boosters.

Frequently Asked Questions

Can this splitter output 4K to all four displays at once?
Yes, it supports sending the same 4K x 2K @60Hz signal to all four HDMI outputs, provided the source and displays support that resolution.

Does the unit extract audio for external speakers?
Yes, it provides both analog and optical audio outputs so audio can be sent to a receiver or soundbar independently of the displays.

Are long HDMI cables supported?
The manufacturer recommends using HDMI cables 30 ft or shorter of excellent quality; longer runs may require signal boosters or active cables.
