Potentially basic questions about splitting one large portrate monitor into 2.

[TalkSimple]

Hi! I have a very tall external monitor (portrait orientation) on my Mac and I'm experiencing two main problems:

1. Fullscreen apps stretch across the full height - This makes the screen unusable for fullscreen mode since it's too tall
2. Microsoft Teams shares the entire tall display instead of a normal-sized window (half the height)

What I'm looking for:
A way to make macOS treat my single tall monitor as two stacked displays, so:

• Fullscreen apps only use half the height
• Screen sharing tools see two separate displays instead of one very tall one

What I've tried:
I attempted to use BetterDisplay's virtual monitors feature, but I ended up with 4 screens total (my 2 physical displays + 2 virtual ones). The virtual displays wouldn't stay in place and sometimes hid content behind them, making it
difficult to work with.

My questions:

1. Is BetterDisplay the right solution for this use case?
2. If yes, what's the correct way to configure it to split one physical monitor into two virtual displays that stay properly positioned?
3. Is there a simpler approach than the PIP method I might have missed?

Any guidance would be greatly appreciated! I'm willing to purchase the Pro version if this feature works reliably for my setup.

System info:

• macOS on Apple Silicon
• BetterDisplay v4.0.4
• Tall portrait monitor 1920*2160

Huhh. It seems like I missed this one.

Sadly there is no simple solution to this, only a workaround with virtual screens and PIPs. If the display has some kind of vertical PBP support, then that might be a solution. There are hardware video-wall solutions as well, but that would be an overkill.
