    I’m not aware of anyone having tried Atari ST(e) with Pro, but some time ago I debugged one 7800 that didn’t sync. In that case the reason was cable, or fundamentally bad design from Atari. Essentially pin 2 of the AV connector carries either composite video or TTL composite sync depending on the model. If you happen to have RGB cable designed for the other sync circuit type, you may end up with sync level which is either too weak or high enough to potentially damage modern receivers. If the cable is suitable, you could try adjusting Analog sync Vth on Pro’s sync menu (although this should not be needed if sync level is right).
