4K content playback is now supported on Roku 4, Roku 4K TV, Roku Premiere, Roku Premiere+ and Roku Ultra, you can now direct play 4K video with a maximum resolution of 3840×2160 that encoded with H.265/HEVC codec with Plex app on above listed Roku models. However, for other Roku models users such as Roku 3, if you try to stream 4K H.265 to Plex via Roku 3, what condition will happen?
What’s the state of Plex app on Roku 3 with 4K H.265?
As what we have stated above, Roku 3 doesn’t support 4K playback, therefore, PLex will try to transcode the 4K resolution video down to a maximum of 1080p. What’s more, from Roku supported file formats, we can see that Roku 3 can only playback H.264/AVC MKV/MP4/MOV video. It also means that that Plex will also try to transcode the incompatible H.265 codec for Roku 3 playing.
It is well known transcoding 4K content (especially for 4K H.265 codec) can be very CPU-intensive and some lower-powered computers (especially NAS devices) might not be capable of doing so in real-time.
