Is there a way or an application on macOS that would allow me to display on only a part of the screen and fill the rest of the screen with black bars?
I am using an LG 55inch OLED 4K TV as an external monitor. On Windows, I used to set a lower resolution and use center scaling in order to prevent the display to be stretched to fit the screen. So I end up with black bars filling the rest of the TV screen.
I hope I can do the same on Mac.
I would like to add that over/under-scan settings don't show up to me on Monterey OS. Also I tried to use SwitchResX but it doesn't support anymore resolution full customization on Apple silicon, so most of the settings are grayed out.
