I've been meaning to mention on this forum MY solution. Rather than using a coupler and swapping cables, I grabbed this mofo:
HDMI Switch
It's 4K HDR HDMI 2.0 compliant.
It switches between 2 ports.
I have option 1 routed directly to HDMI 1 on the TV. Option is 2 routed directly to the breakout box, which in turn is plugged into HDMI 2 on the TV.
It works perfectly. No fuss, no mess, no damaging cables by constantly coupling and uncoupling.
Edit- I have HDCP disabled too (I don't watch blue rays on my PS4.)
