I recently purchased a 27" iMac. The specs say there are 3 video outputs. I can connect one monitor to my iMac but when I try to connect a second monitor, the second monitor does not receive a signal. If I unplug the first monitor the second monitor will receive a signal. What am I doing wrong?
First, please carefully review the Technical Specifications and see if your machine actually supports 2 external displays. The Tech Specs for a 2020 27" iMac are:
Video Support and Camera
You must be very specific when asking a question, we have no idea what configuration you bought so we cannot answer your question until you tell us what you own and which external displays and their specs you are attempting to connect. Also, I think you may benefit by speaking directly to AppleCare. You can find their phone number by clicking AppleCare contact Information
