Show Cue System

I have one video I want to display on three video screens. I will select one for the audio and mute the other two.
How is the best way to sync them. Three separate cues does a better job with the 2nd and 3rd starting at the start of the first cue.
I tries sub cues, but they seem to be out of sync more.
Thanks, Tom

Seems like you want the same feature as requested in Duplicate screens. Is that correct (apart from the fact that you want 3 screens, not 2)?
