Virtual Screen Passthrough

[kman1898]

Is there anyway we can make a virtual screen pass-through? Think of it like an EDID emulator where the Mac always sees an output regardless of if there’s one connected and then you set a specific output to the virtual screen. Then if the output is disconnected, the Mac and it’s applications essentially don't see that it loses the output as it’s being emulated and then when it is reconnected, it picks it back up as if nothing ever happened.

Well, you can create a virtual screen and mirror it to an external screen - the apps are using the virtual screen and when the external screen is removed, the apps should go on happily on the virtual screen. You can also configure a virtual screen to kinda stand-in for a real screen (provided you use the same vendor/model/serial for it) when it is disconnected, but that won't really be the same as the display ID will change and apps still have to migrate to the new display. Macs currently don't provide a proper uninterrupted output when the display is disconnected, you need a hardware EDID emulator for that.
