Streaming 4K Video to Roku via Plex 

4K Ultra HD gives you a better viewing experience by increasing the pixel resolution – it’s four times that of HD! Nowadays, big-budget films (and an increasing number of TV series) are being filmed in 4K, and you can also record some 4K footage with 4K capable camera or camcoder. For 4K video lovers, you may wish to watch the 4K videos on Roku via Plex so that you can conveniently and remotely control the designed interface from your couch.

 

However, although the Roku Ultra, Roku Premiere+, Roku Premiere and 4K Roku TV models all support streaming 4K up to 60 (fps to give you smooth and clear motion no matter how frantic the car chase or drawn-out the instant replay), the Roku only supports a limited number of local media files like MP4 (H.264) & MKV (H.264) video / AAC & MP3 audio / JPG & PNG image). It indicates that you may fail to stream some 4K videos to Roku via Plex, such as XAVC S, Prores, MXF,etc.

Video — H.264/AVC (.MKV, .MP4, .MOV), on Roku 4 only: H.265/HEVC (.MKV, .MP4, .MOV); VP9 (.MKV)
