Frequently Asked Questions
Can this splitter send 4K to one display and 1080p to the other simultaneously?
Yes, the Blackbird 136741 supports 4K to 1080p downscaling, so you can output native 4K on one display and a downscaled 1080p signal on the other at the same time.
Does this splitter support HDCP 2.2 protected content?
Yes, it is HDCP 2.2 compliant, so it can pass through protected content from streaming devices, Blu-ray players, and cable boxes.
What audio extraction options does the Monoprice Blackbird offer?
It can extract audio via both digital optical (TOSLINK) and stereo analog outputs, letting you route audio to a soundbar or receiver independent of the displays.
What is the EDID copy function used for?
The EDID copy function reads a connected display's identification data and presents it to the source device, which helps resolve handshake issues and ensures the source outputs the correct resolution.
Does this splitter require external power?
Yes, HDMI splitters that support 4K@60Hz and signal processing features like downscaling require an external power source, which is included with the unit.
