Can I Connect an HDBaseT Projector Directly to an OREI HDBaseT Transmitter or Matrix?

Direct answer

In most cases, no. Connecting an HDBaseT projector directly to an OREI transmitter or matrix HDBaseT output is generally not supported for full 4K resolution. If you need 4K performance, connect the projector through the dedicated HDBaseT receiver included with the OREI kit.

Why a direct connection may not work

It is reasonable to expect two HDBaseT devices to work together, but HDBaseT alone does not guarantee that every transmitter, matrix, and projector will communicate the same way. The chipset design inside each device, along with the supported signal formats, determines whether a direct connection will work correctly.

Some OREI transmitters and matrix switches are designed to work with their matching HDBaseT receiver instead of connecting directly to the HDBaseT input on a projector. In those cases, a direct connection may not work as expected, or it may only support a lower resolution depending on the model.

The UHD-EXB400R-K exception

Certain models, including the UHD-EXB400R-K, may support a direct connection to an HDBaseT projector under supported configurations. However, this may limit the output to 1080p at 60Hz. This is a model-specific exception and does not apply to all OREI HDBaseT transmitters or matrix switches.

Recommended connection for 4K

For 4K installations, use the HDBaseT receiver included with your OREI kit. Follow the steps in your specific product manual, since not every OREI kit uses the same ports or connection layout.

1. Connect the source device to the OREI transmitter or matrix as instructed in the product manual.
2. Connect the transmitter or matrix HDBaseT output to the corresponding HDBaseT receiver using the supported cable and connection method.
3. Connect the receiver HDMI output to the projector HDMI input.
4. Confirm that the source, OREI equipment, receiver, cable, and projector all support the desired resolution and refresh rate.

FAQ

1. Can I connect my HDBaseT projector directly to an OREI HDBaseT output?

Generally not supported for full 4K operation. Compatibility depends on the specific model, so check the product documentation before attempting a direct connection.

2. Why are both devices using HDBaseT if they cannot work together?

HDBaseT is the transmission technology, but chipset implementation and supported signal formats can differ between products. Using the same technology does not guarantee full interoperability.

3. Can I get 4K resolution through a direct connection?

Do not assume so. Some models may support direct connections with limitations, such as 1080p at 60Hz on certain configurations of the UHD-EXB400R-K. For 4K, use the receiver included with the kit.

4. What should I do if my projector has only an HDBaseT input?

Check whether the projector also has an HDMI input. If it does, use the included receiver HDMI output as recommended. If the projector only has an HDBaseT input, contact OREI Support with the exact model numbers of the transmitter or matrix and projector to confirm whether a supported solution is available.
