My Roku Ultra will flash a black screen intermittently, ~ once an hour when I stream at 1080P. If I lower the resolution to 720P the flashing stops.
When I use my Game Station or Samsung DVD player at 1080P the display is fine. Only with the Roku Ultra does my TV flash a black screen.
The last 4 months I ‘ve been using my Roku Ultra at 720P to avoid the black screen flashing. My TV has been effectively down graded to a 720P TV.
CAN THIS BE FIXED?
