TCL 55R515

Is anyone getting an error when trying to set the HDR level in the Roku app for the TCL TV is? I keep getting please restart the TV if problem persists when I’m playing on my Xbox one and trying to change the mode to hdr bright. Anyone else seeing this?

The TV was actually a 55R615 not 515. I figured it out. It was on the dashboard of the xbox and the dashboard may not allow HDR to be used so I think the mode wasn't enabling. BUT when I changed it to a game that supported HDR I was able to cycle through the 3 choices of HDR available fine. So I think it was just having something being displayed that allowed HDR to be utilized.

Thanks everyone.
