1. Introduction and Overview
The OREI UHD14-EX230-K HDMI Splitter and Extender Kit is designed to simplify sharing HDMI media content. It allows distribution of a single HDMI source to four remote locations simultaneously, extending up to 230 feet over a single CAT6 or CAT7 LAN cable. This product fully supports 4K Ultra High Definition media content at up to 60 frames per second and is compliant with both HDMI 2.0b and HDCP 2.2, ensuring compatibility with modern media gear.
The transmitter unit also provides local loopback functionality, allowing you to enjoy the content at the primary location while simultaneously sharing it with all four remote locations. The system employs Power over Cable (PoC) technology, meaning only a single power supply at the transmitter end is needed to operate the entire solution.

5. Setup and Installation
Follow these steps to set up your OREI 4K 1x4 HDMI Extender Splitter:
- Connect HDMI Source: Disconnect your media player or HDMI source from its local monitor. Connect the HDMI output of your media player/source to the HDMI IN port on the Transmitter unit.
- Power the Transmitter: Connect the included 12V DC power adapter to the DC 12V input port on the Transmitter. Plug the power adapter into a standard wall outlet. Finger-tighten the locking collar on the barrel connection to ensure a secure fit.
- Connect Remote Displays: Connect an HDMI cable from each of your remote displays (up to four) to the HDMI OUT port on each respective Receiver unit. Ensure you use high-quality HDMI cables for optimal 4K performance.
- Connect LAN Cables (CAT6/7): Connect CAT6 or CAT7 LAN cables from the CAT OUT (1-4) ports on the Transmitter to the CAT IN ports on each of the four Receiver units. These cables transmit both video/audio signals and power (PoC) to the Receivers. For optimal performance, shielded CAT6/7 cables are recommended.
- (Optional) Local Loop Out: If you wish to view the content at the primary location, connect an HDMI cable from the HDMI LOOP OUT port on the Transmitter to a local monitor.
- Power On: Turn on the Transmitter unit using the power switch. The power indicator LED on the Transmitter will light up after an internal self-test. The power indicator LEDs on the Receiver units will also light up once they receive power and complete their self-test.
- Automatic Adjustment: The system will automatically detect the resolution of the media content and the output displays, making necessary adjustments to provide the best possible picture.
