output preview monitor

Running OBS on a Dell desktop and a Blackmagic Atem mini Switcher. Currently two cameras connected to switcher. Unable to see preview or any image on separate monitor connected to "hdmi out" from switcher. Was previously able to see a mirror of our main computer monitor with both cameras when switcher was in "Program Preview" mode in Atem Mini setup window. In Atem Mini setup window, under Panel Settings we changed to Program Preview instead of Cut Bus. In Atem Software Control Window, under "Output" dropdown, we are on preview mode. Still no image on monitor coming from HDMI out from switcher. Any suggestions. Thanks in advance

Multiview won't serve?

Mini doesn’t have multi view.

No great advice to offer except cycle power, replug connections, revert to preview settings and try again, etc.
