Samsung S95C Dropouts Fixed!
After 8 months.. and trying EVERTHING! I found the S95C Dropout fix for gaming consoles and PCs. Can't believe I didn't realize this sooner.
1 - All Settings 2 - Connections 3 - External Device Manager 4 - Input Signal Plus (The culprit!) 6 - Deselect whichever HDMI is having dropouts.. or deselect all of them.
Dropouts fixed and gone!
