hdmi ultra hd deep color

I have a question, Hopefully someone can answer it. I have a 4 k lg freesync monitor that supports 4k 60 hrz on hdmi outputs , but only if the ultra hd deep color setting is enabled . This is an lg 4k display with freezync I use with my gaming pc no problem
. In order to have access to 4k content on my xbox one s. I have to enable ultra hd deep color in the settings for 4k through the hdmi 2.0 ports seeing as xbox does not have display port option. When I enable this my display does not work properly and flashes
here and their , so my question is does xbox support hdmi ultra hd deep color ? I have tried enabling 30 bit in color options in the xbox one s still no go , so is it not compatible with lg ultra hd deep color setting ?? My friend has the same problem only
with his lg tv . Is this an lg issue with xbox ? My monitor has hdmi 2.0 when hdmi ultra hd deep color is enabled .

XBOX ONE S & HDR

Nevermind. Found it. For anyone who might stumble across this, it was in my LG TV All Settings --> General --> HDMI ULTRA HD Deep Color menu.

 

The Xbox One S and my tv

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.
