Frequently Asked Questions - BG-UHD-42M BZBGear

How do I switch which input is displayed on Output A?

Press the OUT A button on the front panel repeatedly to cycle through inputs 1-4. The corresponding blue LED will illuminate. Alternatively, use the IR remote and press 1/2/3/4 under Output A section.

What is the ARC function and how do I use it?

ARC (Audio Return Channel) allows audio from the display (e.g., TV’s built-in apps) to be sent back to the matrix switcher and output via the optical port. Press the ARC button to enable (LED on). Then press Audio A or Audio B to select which output’s audio is returned. Note: the analog L/R output is muted when ARC is on.

How do I downscale a 4K source to 1080P?

Press the 4K→1080P button on the front panel to toggle the downscale function for Output A or Output B. The corresponding blue LED will illuminate. This is useful if your display only supports 1080P.

What does the EDID switch do?

The EDID switch on the rear panel selects how the source reads display capabilities: AUTO passes EDID to all outputs; COPY copies Out A’s EDID to both; STD forces 1080P as default.

How do I extract audio from an HDMI source?

Press the AUDIO button on the front panel to select which output’s embedded audio (A or B) is sent to the optical and analog L/R outputs. The corresponding LED will illuminate.

Can I control the matrix switcher with the IR remote?

Yes. The IR remote allows you to select inputs for Output A and Output B, toggle auto mode, enable 4K→1080P, control ARC, and select audio source. Ensure the remote is pointed at the IR receiver on the front panel.

How do I mount the device?

The package includes two mounting ears. Attach them to the sides of the unit using the provided screws, then mount to a rack or surface. Ensure proper ventilation.

Why is there no video signal on my display?

Check that the HDMI cable is properly connected, the source device is powered on, and the correct input is selected. Also verify the EDID setting is appropriate for your display. Try a different HDMI cable or input.
