I have a Roku Express, and when I stream anything in 1080p, there is a vertical green bar (looks like the Matrix), offset to the right, that sometimes pops up. This doesn't happen when in 720p. It only happens with streaming. I have a new, higher-end Optoma laser projector (1080p), 8K passthrough Denon receiver, and Dish network. This doesn't happen on any DVR playback. Any thoughts would be helpful.
