Description of issue / Feature request

The videos are not shown as spanned across the screens, although the settings are correct in the Aerial settings.
Any way to fix this?

Please make sure :

• you are running Aerial 3.3.4 (latest)
• you actually have Aerial selected as your screen saver for all screens, and not Apple's own implementation that doesn't support spanning :
  
• On that same screen, make sure that "show on all spaces/screens" is checked top right too

Apple does silently disable your selected screen saver on upgrade to Sonoma, so it's very likely you are not running mine.

Hi,

yes, I am running 3.3.4, have selected Aerial as "show for all spaces", and have selected the Aerial screensaver under "Other Screensavers" in settings.
In the Aerial settings itself, I have selected "Play videos on: All displays" and "Viewing mode: "Spanned", Aspect "Fill screen".

Any thing else that could fix this?
Thank you!

Thanks for your quick follow up !

Can you go into System Settings, displays, and make a screenshot of how you have aligned your screens ?

The only thing I can think of is you have a less than 50% vertical overlap between displays, there's a discussion here that you may be interested in, it might be what you are experiencing ?

macOS Sonoma completely broke multi monitor support, we do have a "decent" workaround but as we found out recently, there are some edge cases where it still fails. Apple did ping me about that bug - somehow - so maybe they'll ultimately fix the root issue.

In any case, let me know about your alignment, there might be something I can glean from it, there also could be another edge case we haven't encountered yet for our workaround.

Since they are on top of each other, I guess the vertical alignment is 0 :D
This setup did work with previous versions though.

I'll try to test it and let you know !

This was a fine setup under macOS 13 but macOS 14 broke everything again, so, yeah, annoying. I'll try to get back to you asap.

[WetTiger]

Thank you! And no rush, I'll use "cloned" for now.

Can confirm your configuration trips up whatever mess they made in legacyScreenSaver. I reported it to Apple again...

I may have a workaround for "simple" cases like yours when both screens have a different resolution in the meantime, I'll get back to you!

Aerial not spanned across multiple displays? Any fix?

@anthonybaldaccini follow the steps here : #1334 (comment)

This should fix it, it's probably not enabled and you're using the sonoma thing.
