Zoom will not connect to my second monitor. The second monitor works. I have the right Zoom settings

A month or so ago my Zoom stopped connecting to my second monitor. I have the correct setting for 2 monitors. I have unplugged the second monitor and replugged it etc. I use my account on two different computers, so made sure my single monitor set up was also set for 2 monitors (first computer on the account.) Nothing is working to get Zoom to use 2 monitors. What else can I do?
