I have a projector, Arc, Amp and 2 Subs. I had purchased an HDFury Arcana and had nothing but issues with the unit their tch support helped as much as they could.
So I purchased a new Epson projector, LS12000, with eARC. Source is a 4K Apple TV.
The CEC works perfect from the Epson remote control. The system is now reliable enough for my family to use. I’ve also remapped, using Pro Control, a Lutron Pico to control the projector and lighting in the room. One button turns on the projector and lighting and another turns everything off.
Next, I’ll be looking to hack the Atmos and install in ceiling speakers and use the internal amplifiers, hopefully it’ll offer better sound.
