OREI support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I contact OREI technical support?

    You can contact the OREI support team via email at info@orei.com, by phone at 877-290-5530, or through the live chat feature on their website. Support hours are Monday to Friday, 9:00 a.m. to 5:00 p.m. Central Time.

  • Where can I register my OREI product for warranty?

    You can activate your warranty by registering your product online at www.orei.com/register.

  • What should I do if my HDMI extender shows no video output?

    Troubleshooting steps may include: 1) Ensuring source resolution does not exceed the extender's limit (e.g., try 1080p if 4K fails), 2) Checking that high-quality CAT6/7 cables are used, and 3) Verifying that all HDMI cables are compliant with necessary standards (like HDMI 2.0 or 2.1).

  • Do OREI splitters extend the desktop or duplicate it?

    Most standard OREI HDMI splitters are designed to duplicate (mirror) the source screen to multiple displays. For extending a desktop to show different content on multiple screens, check if the specific device supports MST (Multi-Stream Transport) mode, which is more common in DisplayPort products than standard HDMI splitters.
