I don't know if that's true. I think their monitor software has more than video out, they had the camera software running on the phone, so I think you could effectively operate it from the phone. Plus it was meant to be a cheapo replacement for their professional monitors specifically made for those cameras, which are very expensive.

They had a value proposition there, just... for a tiny narrow band of people who somehow owned one of a handful of very expensive cameras but were more willing to replace their phone instead of writing off the cost of additional hardware.

I think their original idea was for Youtubers and streamers using their cameras to set up with those and then complement their setup with their phone. The earlier phones came with streaming software built right in for some form of multicam streaming. It was nuts how specific the whole deal was. Fortunately setting things up like that required a lot of common sense features other phones have given up on, so now all three of us just can't go back to Samsung spyware platforms or whatever normies are using these days.
