Operating Instructions
The OREI UHD-PRO102 is designed for simple plug-and-play operation. Once all connections are made and devices are powered on, the splitter will automatically manage the video and audio signals.
Automatic Downscaling

The splitter features an automatic downscaling capability. If you connect a 4K source to the splitter and have one 4K display and one 1080P display, the splitter will automatically downscale the signal for the 1080P display while maintaining 4K resolution on the 4K display. This ensures optimal viewing on both screens without manual adjustment.
EDID Management
The advanced EDID (Extended Display Identification Data) management ensures that the source device outputs a signal compatible with the connected displays. The splitter intelligently reads the EDID from the connected displays to provide the best possible common resolution and audio format.

Troubleshooting

- Audio Problems: Confirm that your audio settings on the source device are correctly configured. Ensure that your displays or audio receivers support the audio format being transmitted.
- Flickering/Intermittent Signal: Try using different, high-quality HDMI cables, especially if they are longer than 30 feet. Ensure there are no loose connections.
