This unit is a great video monitoring solution but does not come with a power supply.

Using this Blackmagic Design MultiView 4 HD is easy. First, connect it to your video source. You'll need to provide your own power supply to get it up and running. When using it, make sure the connections are secure to avoid any signal issues. For maintenance, keep it in a clean and dry place. Regularly check the connections and the device itself for any signs of damage. If you encounter any problems, check the connections first and then refer to the official documentation for further troubleshooting.
