my bad, after installing their soft the 4K is available ;-)

hI, I bought webcam settings on App Store in order to set manually focus and brightness from the FaceTime webcam of my laptop, but on Catalina I couldn't take control over my webcam , anyone managed it? Thx

I too have a C920. But I did remove the LogiCapture software. Sometimes Isadora did not see the camera at all if I had opened the LogiCapture software at all that day. A restart fixed that. But for me once it works it was fine. Maybe remove the LogiCapture software and see? Not sure how else I can help here really. Sorry.

@dusx  The problem was solved !! The graphic card configuration was the problem. No more crashes Thanks a lot ! Best, Maxi 

@mc_monte Has one of these I think
