Good afternoon, I got a sudent problem with my iMac and my 2 displays. it was working well since a year and now without any change, when my 2 displays are connected it start to flickering and my display stop every 5 second 1 by 1.
When my iMac isn't connected to them it work well.
Any idea how to fix my issue please.

If truly nothing has changed, then most likely something, component or components, has experienced a fatal event.
How old are all your various devices? How do you know nothing has changed as Macs do have background processes that often update automatically. Have you had any error messages of any type leading up to the failure? Has any of the devices acted oddly but still functioned? Any intermittent problems? Have you moved the devices around and possibly loosened connections? Lots of possibilities.
