Fire TV 4k + Plex + 4K TV = Problem/bug

I Found a problem/bug, Ok first the setup.

1) If you hold Select & Down Arrow (at the same time) for 5 sec. then release and push the menu button a dev menu pops up.
2) Enable System X-ray (it will show you system stats)
3) If you look on the top left you will see where it shows you what mode the fire tv is currently in

Ok now the problem, from what i read on the forum is that fire tv dont switch to 4k mode unless you have a 4k h.265 movie playing, from what i found out this is false. If you open youtube app, as soon as you open the app you will see that the fire tv switched to 4k mode (but when you open plex it stays in 1080 mode). So saying that the only way to get to 4k mode is to play a 4k h.265 movie is not true. If plex program the plex client to start in 4k mode even if you play a 1080p movie/show/whatever it will be played in 4k mode (test it open youtube and play a 1080 video it stays in 4k mode it dont switch). So people like me who have 4k movies in H.264 format, if fixed, will be able to watch them in true 4k. Would love to hear back from a dev about this or anyone else.

    I've noticed the same thing with my Plex app for FireTV v2. Trying to stream a H265 4k file from Plex Cloud. It plays fine, no buffering, no skipping, but will only play in 1080p. I can't for the life of my get the TV to recognise it as a 4K file. YouTube, as you mention, automatically switches to 4K mode.

    I've used the steps above, and mine is outputting in 1080p 60FPS (HDCP 2.2) with a HEVC 3840x2160 movie file.

    I was running in to the same problem, so did some research and found the dev menu. Im hoping devs fix this problem/bug. seeing as they advertise that plex on fireTV v2 support 4k when in truth it dont. Im going to chuck this up to amazon change the way 4k works in a firmware update, and not plex lying to its customer. Im hoping this gets fixed ASAP seeing how slow plex devs are to fix bugs sometimes <.<

    I have this same problem. I can transcode (eww) some h264 content to h265 to get a file that will direct play. However the Fire TV remains in 1080p, the same as you.

    I went through the arduous process of capturing logs and submitting them without any results. After whatever symptom @MovieFan.Plex expected didn't appear, I decided not to waste any more time on this problem. To put my money where my mouth is, I also cancelled my monthly Plex Pass.

    Areas Plex needs to improve:

    • Document "supported" hardware. There is no guide for getting 4K content to direct play on a Fire TV. Please correct me if I'm wrong--I had to scrape the forum. (FYI use h264 for at most 1080p content. You must use h265 for 4K content.)
    • Cease false advertising. I have yet to get Plex to deliver 4K content to my TV. https://www.plex.tv/apps/streaming-devices/amazon-fire-tv/ makes it a selling point!

      4K glory
      Enjoy your 4K media in all its beauty with the latest generation of Amazon Fire TV devices. With four times as many pixels as 1080p, Plex looks even more gorgeous.

    • Address this problem. Not only is it difficult to even get 4K content to direct play, once it does play, the Fire TV still pushes a 1080p signal.

    To reiterate: I have a Fire TV Generation 2 capable of 4K output. I frequently view 4K content through Amazon, and until recent events, 4K content through the YouTube app. My content does play back through Plex on the Fire TV without any transcoding--Direct Play shows on screen within Plex--but the Fire TV still spits out a 1080p signal.

    Best of luck to @Alacardjr and @ZeusMedia.TV
