I have a plex server and no problem watching 1080p content on other plex devices like my Tivo or my TVs built in plex app.
Is this just me or do others get 1080p in Plex? Anything I can do about it? [Yes, I have the Roku set to 1080p].
In fact, I didn't find any roku channel doing 1080p, including Amazon Prime. I don't have a netflix account, but another forum member with the same Roku (3400x) and firmware (9.0.0) confirmed that although their roku menu is in 720p, it switches to 1080p when they watch netflix....
edit - updated problem based on post 3 advice.
