The issue I described with the Nintendo Switch was resolved by changing the RGB settings in the Switch console from "full" to "limited". This completely eliminated the problem. I didn't notice a significant change in picture quality so for now I've just left it this way. After a few weeks, out of curiosity, I changed the RGB settings in the Nintendo Switch back to "full" and the issue immediately came back. I've seen several posts online describing the same issue with the Nintendo Switch so it's not just my unit. I hope they fix it in a firmware update. It is not fixed in the current latest firmware, at the time of this posting. I haven't experienced similar signal loss on other devices, but I have not tried a Playstation or a Comcast device, so this may not be helpful to you.

Samsung Q80T HDMI4 Intermittent Signal with Nintendo Switch So we have a new Samsung Q80T 65” and a new Nintendo Switch. Switch is connected to HDMI4.
