Screen mirroring used to be so simple. Now it's difficult just to view a movie from my iMac hard drive to projector. Why is that?

i would need to know a few things to help.

what year is your Mac?

what adapter are you using? and

what is happening when you try?

i used to use a projector, now i have an HDTV. i'm also on a newer mac since my projector days. however, the only change i made was a new USB-C to HDMI adapter vs. a mini DisplayPort to VGA adapter with the old setup. the mirroring options (in display preferences) were the same for both setups.
