Frequently Asked Questions - EXH-50C BZBGear

What is the maximum transmission distance?

The BZBGear EXH-50C can extend HDMI signals up to 164 feet (50 meters) over a single Cat5e/6/7 cable.

Does it support 4K resolution at 60Hz?

Yes, it supports up to 4K2K@60Hz 4:4:4 (8-bit) and 4K2K@60Hz 4:2:2/4:2:0 (10/12-bit) with full 18Gbps bandwidth.

How do I connect the IR extender for source control?

Connect the IR blaster to the IR OUT port on the transmitter and place it near the source device. Connect the IR receiver to the IR IN port on the receiver. This allows you to control the source from the remote location.

Can I use Cat5e cable instead of Cat6?

Yes, the extender works with Cat5e, Cat6, or Cat7 cables. For optimal performance, especially at 4K@60Hz, a high-quality Cat6 or Cat7 cable is recommended.

Do both units need power?

No, the extender supports Power over Cable (PoC). Only one unit (either transmitter or receiver) needs to be powered with the included 12V/1A adapter; the other unit receives power via the Cat cable.

What is the HDMI loop output used for?

The HDMI loop output on the transmitter allows you to connect a local display (e.g., TV or projector) to monitor the source signal without additional splitters.

How do I update the firmware?

Use the SERVICE port (Micro USB) on either unit to connect to a computer. You will need the firmware file and update tool from BZBGear support. Refer to the manual for detailed instructions.

Does it support HDR content?

Yes, the EXH-50C supports HDR (High Dynamic Range) pass-through, including HDR10 and Dolby Vision, depending on source and display capabilities.

What audio formats are supported?

It supports LPCM 2.0/5.1/7.1, Dolby Digital, Dolby TrueHD, DTS-HD Master Audio, DTS:X, and more. See the manual for a full list.

Why is there no picture or signal?

Check that both units are powered (green LED on), the Cat cable is securely connected, and the EDID is correctly copied. Try a shorter cable, ensure HDCP compatibility, and verify the source output resolution is supported. Also, ensure the IR connection does not interfere.
