These instructions seem crazy to me.

The A/V output display must be set to 3840 x 2160 - that part is correct, but AFAICT that is the only correct one.

So here is my short version:

1 - Set the resolution of the Samsung display appropriately

2 - In Final Cut Pro->Settings->Playback, select the Samsung display in the A/V Output popup

3 - Window->A/V Output

4 - There is no step 4

Now this concerns only the A/V Output part, but it may also help in the Secondary Display, because if the A/V Output is already on, FCP will use the remaining display...

Let me know how it works.

So that is the deal, the Samsung as always been set to 3840 x 2160, that part has never changed, and yet the system still pops the display in the home screen until I do that process I just told you about. Always the same thing, I get the alert, the app is trying to send to the Samsung, but nope, pops up on Home Screen, and locks out the drop downs since it's attempting to go fullscreen on itself, so I have to click on another desktop to reveal the drop downs so I can click off the A/V Output. Here is the resolution setting of the Samsung.

Here's what it looks like when A/V in enabled

And here is what it looks like when I try to close the A/V output.

Notice lack of drop downs. Hope that gives you a better idea of what I am dealing with.

OK, now, brain storm, I have now shortened the list of things to do down to a simple change resolution in Preference panel. So set Samsung to 1920 x 1080, then hit A/V Output, screen does it's lay over thing.

As you can see above, since we set the resolution to 1080, the overlay is now only a portion of the screen, Now set resolution in Preferences to 3840! And it pops into the Samsung like it should! Well that is a way better process.

AHHH! That's what I was missing! DURP! Thanks!

Also, when I hit reply to your messages, do they attach to your thread? When I send them, they all land at the end of the main thread on my end! Why can't I reply like below? Screenshotting the reply isn't that efficient! I hit the Reply button under the thread I want to respond to. Something I am missing, this is what I get for not using this forum on a regular basis. 😳

Something is really weird.

A/V Output should have no effect whatsoever on your displays.

I don't know why this is happening.

You should be able to have your main FCP window on one of the Studio Displays,

optionally the Viewer (or Timeline or...) in the secondary display, AND also the A/V Output

on the Samsung, all at the same time.

Why it is behaving like this, I really don't know.

Just to make sure: you did select the Samsung as the A/V Output in

Final Cut Pro->Settings, right?

Yup, it is set as it should be.

Anyway, this saves me from having to go the Blackmagic route, so now I can save up for that 42inch OLED that I want to get for a better client monitor. Then use my Datacolor to color match all the displays!

Thanks for all your help again, you last post triggered that thought in my head on how to reduce the process down to just a couple of hops instead of the whole flipping back and fourth screen thing.

I have that option mapped to my Loupedeck what to show in the secondary display, again, it depends on which display the system boots back up into. I did you one better on deleting preferences and performed an Option launch to reset the entire app, I have done this a few times over the years with the same situation. It's rather annoying TBH. That solution fixes other issues that rarely come up and is a useful tool for launching any app in MacOS. I'll try that Etrecheck app here shortly.

So the system assigns or used to assign screen ID's, you would see them in the Display setup in system preferences, Screen 1, Screen 2, so on and so fourth. I suspect that those ID's get swapped like in my case, so the desktop will be in screen 2 or 3 and so the ID for that screen gets swapped. That's the only way I can explain it.

I hate being level 1, this shows you how often I use this system, as I have now reached my posting limit! 🙄

On a side note, since I installed and removed a few critical pieces of software, the system had to restart and now the correct display has been ID'd. The client monitor, see how long this holds out for.

The A/V output, which has never really worked for me, still attempts to load in the home desktop and not in any of the other 2 screens. BUT, I got my secondary Samsung client monitor back for now. Just a matter of time before the next restart! I really want to know what is happening here, the issue has been most vexing.
