Blackmagic Hardware Types
There are a number of ways to route an SDI or HDMI signal out of and back into your machine, depending on your particular Blackmagic hardware. You will need to send an SDI / HDMI signal out of your Blackmagic hardware and back into either the same or different Blackmagic hardware, essentially creating a signal loop.

- UltraStudio HD Mini
- UltraStudio 4K Mini
- UltraStudio 4K Extreme 3
- Intensity Pro 4K
With these devices, you can send an SDI / HDMI signal out of the device and back into the same device (creating a loop), which can then be added to LDE. If the number of I/O ports is limited, you can send a signal out of the hardware device and into a broadcast monitor, and then from the broadcast monitor (eg. SDI loop) back into the hardware device. You can also use an HDMI Splitter instead of a broadcast monitor loop.
Out-Only Devices: Blackmagic hardware that has SDI / HDMI outputs only​

- Decklink Mini Monitor 4K
- UltraStudio Monitor 3G
With these devices, you would need to additionally use a device from either Category 1 or Category 3 to get the SDI / HDMI signal into the machine that LDE is running on (this can either be the same machine that the Category 2 device is attached to, or a different machine).
