HDR causing screen to flash black randomly

This is EXACTLY how my system is set up. Sound is working perfectly but the video is flashing. Not a constant flash but mainly a black screen then as if the HDR mode keeps resetting, the banner in the upper right corner of the screen signifying hdr has
initialized will get brighter, image that should be showing on screen will appear for a split second and then back to black screen all while the atmos sound never waivers.

My TV (LG 60UF7300) has the HDMI Ultra HD Deep Color as well. According to the Xbox One S support page, this is another name for HDR 10. Unfortunately, I've been having an issue with the Ultra HD Deep Color turned on. It's causing my screen to flash black
pretty frequently. It also says that HDR is turned off and that I can turn it on on a different menu, but the option is not selectable.

I’m having the same issue, but its on the Xbox One X, and its only with HDR. Screen will flicker on and off randomly. If i wait long enough screen will stay black, never come back. I had to disable HDR on the port, flicker goes away ( so does hdr). Everything
worked before the most recent update. Happens on every port, and only happens wjth my xbox. Thoughts?

Not sure if this helps but some TVs when the console detects HDR content certain TVs will automatically switch to your HDR settings which causes the screen to go black and them come back on I have a LG OLED and this happens to me alot
