My current setup is a Visio PX65 hooked up to an Onkyo TX-N585 and the roku ultra hooked up to the onkyo. Recently I have been having an issues where the roku will default to 1080P. I can manually set it to 4K but once the roku reboots it is back to 1080P. I have also since hooked an AppleTV up and it connects at 4K everytime.
I would like to use the roku at 4K and ideas on what I may be able to do?
I have the Roku Ultra. Yes I goto the Display setting and select either of the 4K options it test fine and then I select OK to keep settings... Once the device reboots I get a screen stating the display settings were change back to the 1080P and I once again need to go back to setting to get 4K.
