I have a 2019 27' iMac and for years I have had no issues with the 2nd display, but now it won't detect my 2nd monitor (LG 34'). This happened right after I upgraded to Monterey 12.4. I was hoping that 12.5 would resolve the issue but it hasn't. I've tried all the 'fixes' on this forum and nothing works. This issue has severely impacted my job performance. Please advise!
