Atem Mini and Hollyland 400 Problem?

ATEM mini and Hollyland 400 problem Hey guys! Maybe you know whats going on. So, ATEM Mini user here. I have my Hollyland 300 plugged into HDMI1 and Hollyland 400 plugged into HDMI 2. This way everything is working perfectly. But if I plug the 400 into HDMI 1, I get a picture that looks as if it were fake colors. I have two 400's and both introduce the same fake color image on channel HDMI 1 only. No problem with 400's on other channels. No problem with 300's on ANY channels. Just the 400 on channel one.
