I'm running a new iMac Pro 10c with a USB-C hub with HDMI out. The HDMI -> DVI cable goes in my 24inch JVC DT-V24L1D broadcast monitor. Video Preview out is NOT working in AE, while it works perfectly in Premiere Pro ! And I troubleshooted almost everthing I know. Reconnected the HDMI, because I've read AE sometimes maps video wrong? Tried other USB-C ports. Switching live between Premiere Pro and AE, hoping AE picks up the videolink. Turned on/off mercury and choosing OpenGL/METAL and Software mode. Nothing seems to work! I'm very angry and frustrated because I'm a pro motiondesigner and I bought the 5k JVC screen + 2k blackmagic in 2011. And AE NEVER ever outputted the preview on external monitor in realtime. Previews were always at 15fps! Now after so many years and the introduction of USB-C -> HMDI I wanted to give it another shot... grrr still buggy as hell. I hope someone can help me out, so I can finally start using that JVC screen. My AE setup. My Premiere Pro layout. This works perfectly. It outputs 1080p to my JVC LCD when scrolling the timeline of the clips.
