We connected our Roku Ultra to our new Vizio PX65 4K (Costco). The Roku display auto set itself to 4K HD 60 and every few seconds it blinks in a cycle between a black screen and normal display. setting to 4K HD 30 resolves this. Is there a fix for this?
Thanks for reaching out to let us know what you are seeing.
- Have you tried swapping out the HDMI cable in use, and/or trying different HDMI ports on the TV to see if that helps clear up the issue? - Does this occur when you are simply viewing the Roku home screen, when you are trying to play content in a streaming channel, both, etc.? - Does this issue occur when you try to watch any streaming channel, or only on specific streaming channels?
With more information, we can continue assisting from there.
