# Set up and enable MultiViewer

MultiViewer displays a custom mix of video sources including Channel on the HDMI output port in a convenient grid for confidence monitoring with minimal impact to the system's processors. MultiViewer features differ by Pearl Nano:

- **Pearl Nano** - two video sources. Side-by-side grid.

The HDMI pass-through port only displays the identical video signal with audio that is received at the HDMI IN port on Pearl Nano.

Save processing power so you can do more with your Pearl Nano while previewing multiple video sources on the HDMI output port. With MultiViewer, the video output displays at a lowered frame rate to economize CPU usage. Using MultiViewer does not lower the frame rate of channel recordings and live streams.

No audio signal present at the output port, but audio meters do display for Channel and video sources that have embedded audio signals.

Use the Admin panel to choose which video sources appear in the pre-configured MultiViewer grids and to set the video output port resolution. You can enable MultiViewer for the output port using the Admin panel, the Pearl Nano screen, and using local console.

Deleted network sources or Channel may appear in MultiViewer.
