The problem I am having is when going to picture mode settings, all that are available are "Entertain" and "Standard" when connected to the Roku Ultra. When not connected I have a bunch more. I am connected to a 2013 Samsung F8500 plasma TV. My question. Is there a way to shut off HDR on the Ultra?
Settings/System/Advanced System Settings/Advanced display settings>>
You can toggle these
Would that be the display refresh rate?
