I’ve suddenly run into a problem when streaming through the BT Sport app on my Roku Streaming Stick+. It’s just started turning the screen really dark as soon as I join the live stream. All good while I’m in the menu but as soon as I go into a live stream it goes dark. It also sorts itself once I go into either Manager or Hype mode. I’ve restarted the Roku but doesn’t make any difference. Assuming it’s a bug that needs an update?
My Roku's fine.
Presumably your TV has different picture settings for different inputs (live TV, HDMI, etc) I suspect your problem lays there.
