Yes, the displays do provide feedback.

Do you have full feedback from the displays?

Thanks Steve,
Then how would a person create the following condition?
Display A + B can be powered up separately, but depending on what source has been selected they both may or may not need to be powered up at the same time. And here is the kicker, they both have different warm up times, and the "system is warming up" page needs to be held high during the power up cycle.
So if A takes 10s to warm up, but has been powered up at the same time as B (which takes 20s), the warm up page needs to be high for 20s.

From a more abstract/best practices standpoint, you should try to keep
the amount of timed events (steppers, delays, one-shots, etc...) you use
to a minimum. That said, I'd bet you'd need to use a >lot< of steppers
before the burden they put on system would be perceived by the
operator. Lots of variables at play and the real world threshold will
likely vary (greatly) from system to system. Note that the previous
statement(s) should most defiantly not be translated into anything like
'stop using timed events if you want your systems to work right'.
From a logical/program flow standpoint, I prefer to avoid timed events
and build logic that is condition dependent. Example: I don't
necessarily want to send an input swap command to a projector based on a
specific amount of time having passed, but rather based on real-time
conditions like the (actual) power state and current input selection.

I know there are several ways to skin a cat in Crestron world, and I am always looking at improving and following best practices. Having said that I have a question.
Is it bad to have 2 or 3 steppers running concurrently? Depending on the device being used, I like to have a stepper handle the procedure.
For example, source is selected, stepper for projector 1 is triggered, this fires up the proj and sends down the screen, whilst indicating the system is warming up.
If a different source is selected, it might be destined for other displays, which in turn will trigger their respective steppers.
So there might be a few steppers running at the same time.
