FX30 Live-streaming Problems

[mixnchris20]

Hello, I bought the FX30 for live-streaming and content creation from my desk. I set up an HDMI to HDMI using a capture card (elgato) and am noticing a flickering or glitch on screen when using Zoom, OBS or other live streaming software. I have it set up on 4k 15p and backed down to HD 1080 and still glitching. 

I am hoping I can get 4k out of the camera when live-streaming and can solve the glitch on the screen. What am I not doing or doing wrong? I tried an 8k HDMI cord and still glitching and limitations on output settings.
