Alternative for UltraStudios for output

I am working with a church and they are looking to out put video from vMix on to a projector. In the past, they used propresenter with ultra studio converters for their projector, but they have had to replace them once every three months and sometimes the firmware would bug out. They want to have a similar solution for a clean feed out of vMix without using the BMD ultrastudios. As far as I no, none exist. Does anyone know of any alternatives?
