Yeah, I'm watching this unfold and I don't see how the other person can't see the problem.

Someone spends a thousand, or two thousand dollars on a high-end device with state-of-the-art ports and graphics and processing, and because "OS notifications sometimes pop up if you don't disable them", real pros buy a piece of middleware hardware that does nothing but filter out a software issue?

Yes, exactly. If you need to be able to control what goes to the display and take that away from the OS, you need a hardware I/O device.

OS notifications and alerts are just examples of any number of things that could be displayed that are unwanted. In situations where something like that makes the setup "unusable", you have to have a hardware I/O device. There's not another option.
