Very disappointed that leaving many of us behind....why would Roku do this and not have Dolby Vision 30 hz option as in the past....fix this please....upgraded and now regretting
I don't have a B8, but typically DolbyVision at 60Hz requires that "Ultra HD Deep Color" is enabled. It is set for each HDMI port individually and it is disabled by default. So you'll need to go into Tutuapp9AppsShowbox the HDMI port settings for whatever port the Shield is plugged into and enable it.
